Show morePrevious research has investigated vocabulary and fluency as predictors of reading comprehension, most of it concentrating on younger school-age readers. The present study compared both passage-specific and generic assessments of vocabulary and fluency as predictors of reading comprehension in college-age readers. The comparison was done for both standardized tasks and experimental tasks and for expository and narrative text types. The study also investigated the effect of text type and question type (inferential and non-inferential) on reading comprehension. Seventy eight college-age readers completed a battery of reading comprehension, vocabulary and fluency tests. The results of the study reveal an interaction between passage type and question type on comprehension performance with students performing better on inferential questions for narrative texts, and on non-inferential questions for expository texts. Furthermore, vocabulary was found to be a better predictor of reading comprehension than fluency for both standardized and experimental tasks.

Title: Intentional Binding of Negative Items in Memory.
Creator: Zimmerman, Carissa A., Kelley, Colleen, Eklund, Robert, Charness, Neil, Kaschak, Michael, Plant, Ashby, Department of Psychology, Florida State University
Abstract/Description: Memory for individual negative items, such as words and pictures, is consistently superior to memory for individual neutral items; however, recent research has found that relational memory for pairs of negative items is not enhanced relative to their neutral counterparts. The current experiments investigated the boundary conditions for this lack of negative associative memory enhancement and repeatedly found that memory for negative word pairs was not better than memory for neutral word pairs...
Show moreMemory for individual negative items, such as words and pictures, is consistently superior to memory for individual neutral items; however, recent research has found that relational memory for pairs of negative items is not enhanced relative to their neutral counterparts. The current experiments investigated the boundary conditions for this lack of negative associative memory enhancement and repeatedly found that memory for negative word pairs was not better than memory for neutral word pairs. In fact, cued recall of negative stimuli exceeded that of neutral stimuli only when word pairs were encoded holistically, as in the case of adjective-noun pairs. Findings are discussed in terms of the important dissociation between item and associative memory, and the implications of this distinction for theories of emotional memory in general. Finally, a discrete-emotion approach to emotional memory is introduced as one fruitful avenue for exploration.

Title: An Item-Specific and Relational Processing Account of Emotional Memory Enhancement.
Creator: Zimmerman, Carissa Ann, Kelley, Colleen M., Kaschak, Michael, Plant, E. Ashby, Department of Psychology, Florida State University
Abstract/Description: Two experiments tested the competing item-specific and semantic cohesion hypotheses of emotional memory enhancement. The item-specific hypothesis predicts that emotional words receive more item-specific and less relational processing than neutral words, whereas the semantic cohesion hypothesis posits more relational processing of emotional words. In both experiments, emotional words were better remembered than neutral words. However, Experiment 1 found no support for either hypothesis;...
Show moreTwo experiments tested the competing item-specific and semantic cohesion hypotheses of emotional memory enhancement. The item-specific hypothesis predicts that emotional words receive more item-specific and less relational processing than neutral words, whereas the semantic cohesion hypothesis posits more relational processing of emotional words. In both experiments, emotional words were better remembered than neutral words. However, Experiment 1 found no support for either hypothesis; emotional and neutral words did not differ in the amount of either item-specific or relational processing, as measured by item gains and losses across repeated tests. Experiment 2 found that the memory advantage of emotional over neutral words did not differ as a function of the type of orienting task in which participants engaged. Several methodological explanations for the absence of the hypothesized findings are discussed along with future directions for research.

Show moreValidating the structure of early numeracy skills is critical to understanding the developmental trajectories of mathematics skills at early ages. However, little research has been devoted to construct evaluation of the Counting, Numerical Relations, and Arithmetic Reasoning domains. This study was designed to address this gap in the literature by (a) developing a broad and deep measure of Counting skills, Numerical Relations skills, and Arithmetic Reasoning skills, (b) examining the structure of these three skill domains, and (c) examining the relations between these three domains. In Phase 1 of this study, measure development was conducted using a sample of 306 children (50.5% girls; 46.9% White, 41.0% African American, and 12.1% other). In Phase 2, further measure development was conducted as well as evaluation of the structure of and relations between the three domains using Confirmatory Factor Analysis. Three hundred ninety-three children from the Tallahassee and Panama City areas in Florida participated in Phase 2 (51.7% girls, 55.7% White, 33.8% African American, and 10.5% other). Results indicated that the relations between the early numeracy skills were best explained by a three-factor model of Counting, Numerical Relations, and Arithmetic Reasoning. The findings from this study provide a strong foundation upon which to build future research in early numeracy skills.

Four studies (N = 570) found that belief in free will facilitated learning from emotional experiences, as deterministic beliefs were associated with reduced learning. Studies included both correlational (Study 1) and experimental (Studies 2-4) designs. Emotional responsiveness, as defined by low psychopathy scores, also facilitated learning from emotional experiences (Studies 3 and 4). The degree of learning associated with emotional experiences was measured by self-rating (Studies 1 and 2), independent evaluations of lessons learned (Study 3), and whether participants joined a campus recycling program (after being made to feel guilty about an environmental transgression; Study 4).

In Study 1, participants subliminally primed with the names of their family members subsequently performed better at an open-ended language task relative to participants primed with neutral words. Study 2 addressed two alternative ways of interpreting the results of Study 1. Participants in Study 2 who wrote a short essay about a family member with whom they had a good relationship demonstrated more self-control than those who wrote about a humorous episode or an enemy relationship, as measured by their performance on a simple but tedious math test. Study 3 was designed to demonstrate that self-control, rather than motivation, was affected by thoughts of the family. Participants primed with a visual cue of a family member ate fewer cookies than those not primed—when individual differences in eating restraint were controlled.

Title: Cannabinoid Signaling in the Auditory Brain Stem of the Chick (Gallus Domesticus).
Creator: Stincic, Todd L., Hyson, Richard, Logan, Timothy, Johnson, Frank, Meredith, Michael, Licht, Mark, Department of Psychology, Florida State University

Show moreNucleus magnocellularis (NM) is a cochlear nucleus in the avian auditory brain stem which solely receives excitatory input from the auditory nerve fibers of cranial nerve VIII (cnVIII) and bilaterally innervates nucleus laminaris. The primary function of NM neurons is to code the temporal characteristics of acoustic stimuli and pass on this information to nucleus laminaris for use in coincidence detection and ultimately sound localization. Robust and dynamic stimuli could easily overwhelm many other synapses, but NM not only faithfully encodes important features of sounds, but can also enhance the information. Synaptic depression is one consequence of the large, rapid currents produced in NM in response to acoustic stimuli. The progressive decline in postsynaptic responses could lead to a failure in temporal coding. Therefore, depression must therefore be managed to allow coding not just at the onset, but throughout the duration of an ongoing stimulus. Many synaptic adaptations can be found at the cnVIII-NM synapse which act to dynamically adjust neuronal signaling in order to maintain consistent coding. GABAB receptors, in particular, present an interesting situation where activity-dependent inhibition can lead to an enhancement of neural signaling. The increase in synaptic reliability is presumably mediated through a conservation of neurotransmitter. The cannabinoid (CB) system represents another type of signaling that can mediate negative feedback, reducing neurotransmitter release. Furthermore the cannabinoid receptor one (CB1) is present in many sensory systems and is found throughout the brain of the chick. Relevant to auditory processing, the ganglion cells which form cnVIII produce CB1 mRNA. Immunohistochemical labeling of CB1 revealed that the calyceal terminals, not the cell bodies, of NM contain the functional receptor. Activation of these receptors with WIN 55,212-2 (WIN), a CB agonist, reduces excitatory postsynaptic currents, most likely through lowering of vesicle release probability. The high safety factor of neurotransmission at the calyx synapse means that a reduction in peak amplitude does not necessarily inhibit action potentials, but does appear to reduce the degree of observed synaptic depression. Endogenous CB production has been shown to occur in an activity-dependent manner, through either activation of metabotropic glutamate receptors or postsynaptic depolarization/intracellular Ca2+ rises. High frequency stimulation was able to induce an enhancement effect in current clamp which was blocked by pretreatment with a CB antagonist. The stimulation protocol was subsequently used under voltage clamp, but did not appear to initiate endogenous cannabinoid production as measured by paired-pulses. This finding suggests that metabotropic glutamate receptor activation is not sufficient to elicit cannabinoid production or paired-pulses are not a good measure in NM. If cannabinoids are produced endogenously at this synapse then the Ca2+-sensitive production pathway could be necessary as it require postsynaptic depolarization which does not occur under voltage clamp. A second way to measure CB effects is to measure the amplitude and frequency of spontaneous postsynaptic events. Picrotoxin, a GABAA antagonist, was used to isolate effects on glutamatergic signaling for study. In most cases picrotoxin had no effect; however, the drug was able to cause a near complete cessation of spontaneous postsynaptic currents in NM. A CB antagonist AM251 had an effect in the other direction and was able to preferentially increase the frequency, but not the amplitude of spontaneous events. These findings demonstrate that the vast majority of spontaneous depolarizing events are from random GABA release and there is a basal level of CB production even in an unstimulated slice. Another possibility is that the deafferentation-induced rise in intracellular Ca2+ caused this CB release. Unfortunately at this time we did not record from NM neurons with both picrotoxin and AM251 present in the bath. This limits our ability to interpret the data as it is not clear if the additional spontaneous events are from increased GABA or glutamate release. We did not detect any CB1 mRNA labeling of the superior olive which is responsible for the GABAergic input to NM. Also, WIN had an effect on depression even with picrotoxin present. This indirect evidence points to glutamate release as the underlying cause for the increased events. This study was by no means an exhaustive examination of CB signaling in the chick auditory brain stem. Rather, we made the first steps toward a new line of research as we now clearly know that CB1 is present and able to modulate signaling at the cnVIII-NM synapse. At this time we do not fully know how, to what degree, and when CB signaling is engaged. The functional purpose of CB would appear to enhance the coding of temporal events, however, we do not know at what scale. CB1 activation could function in a synapse-specific manner, complementary to GABAB activation, reducing synaptic depression at high rates of stimulation. Another, simpler role could be to maximize the signal to noise ratio by keeping the frequency of spontaneous glutamate release low. Further experiments will be needed to clarify these intriguing results.

The 363 children who participated in this study were randomly assigned to one of four intervention groups or a control group. ANCOVA was used to determine the effectiveness of the academic interventions on both early reading skills and behavior. All three academic interventions were effective in improving their respective emergent literacy skills. Analyses of the interventions' effects on behavioral problems yielded no significant effect on inattention, hyperactivity/impulsivity, or oppositional behavior. The lack of change in behavior indicates that behavioral problems may not be altered by participation in an effective academic intervention. However, these findings are limited to the period immediately following the intervention, which may not allow sufficient time for changes to develop. Implications for future research regarding these findings are discussed.

Show moreThe influence of sex and ethnic differences on the accuracy and bias in children's perceived acceptance is an area of research that has generally been overlooked and is important to investigate because such differences may help determine how children will function when interacting with others. Additionally, the way in which children interpret these interactions may in turn impact their mental well-being. The purpose of this study was to examine the influence of sex and ethnic differences on the accuracy and bias of children's perceived acceptance as perceivers (male/female; African American/Caucasian) predicting their social standing among a reference group (same-sex/other-sex; same-ethnicity/other-ethnicity). Archival data of sociometric ratings received from children in grades 3 through 5 (n=923) was used to form measures of dyadic accuracy, dyadic perceptual bias and general perceptual bias. This study revealed the following main findings: 1) children are more accurate in determining their peer acceptance among reference groups of similar sex and ethnicity, 2) girls have overly positive whereas boys have overly negative perceptions of their peer acceptance among same-sex peers at the dyadic level, and 3) African American children tend to overestimate peer acceptance whereas Caucasian children are likely to underestimate their peer acceptance, although the pattern of results differed slightly for dyadic and general bias. This investigation has extended prior research by identifying the sex and ethnicity of children whose self-perceptions are not in line with their actual level of peer acceptance as well as the composition of those peer groups who pose the greatest challenge for them when making decisions regarding their peer acceptance.

The major evidence that fluency is a basis for familiarity is a paradigm where fluency is manipulated by briefly priming participants with an item before asking them if they have previously encountered it, based on Jacoby and Whitehouse (1989). Four experiments were run to see if this effect occurs for pictures as well as words. Experiments 1 and 2 show that priming can increase judgments that...

Experiment 3 failed to show priming for pictures of faces. Finally, Experiment 4 manipulated study time and asked participants to make a Remember/Know judgment. Perceptual fluency is used as a basis for picture memory when participants are unable to use recollective cues.

Show morePrior research suggests praise increases motivation. The present research tested pride and humility as mediators of the effect of praise on motivation. I hypothesized that pride may contribute to motivation because it is pleasant to experience and boosts perceived competence. Humility may contribute to motivation by facilitating less inflated self-assessment and greater awareness of one's room for improvement. In Studies 1a and 1b, participants recalled experiences of receiving praise or non-praise experiences and reported how proud, humble, and motivated they had felt. Participants recalled feeling more proud, humble, and motivated after praise than after non-praise experiences. Both pride and humility mediated the effect of praise on motivation. Study 2 was conducted to develop better ways of assessing humility for use in Study 3. In Study 2, participants watched a video intended to induce humility or a neutral video. Participants who watched the humility induction video compared to participants who watched the neutral video self-reported greater humility and made less inflated self-evaluations. Narcissism correlated negatively with self-reported humility and correlated positively with inflation of self-evaluations. In Study 3, participants received praise versus no feedback from a friend and an expert on an essay they had written. Participants provided self-report measures of pride, humility, and motivation, as well as behavioral measures of effort/motivation. Results were consistent with hypotheses that praise increases pride, humility, and motivation. Study 3 produced no evidence of simple mediation. However, humility showed a marginal pattern of interactional mediation, such that, after receiving praise humility was associated with greater motivation, but after receiving no feedback humility was associated with less motivation. Differences in the praise situation, including the meaningfulness and unexpectedness of the praise, may have produced the divergent findings across studies. Study 3 yielded suggestive evidence that praise may be more motivating for people with high than with low self-esteem. Humility was positively associated with gratitude across studies and tended to be negatively associated with inflated self-evaluations in Studies 2 and 3.

Show moreThis study examined the efficacy of brief functional assessment methodologies, including descriptive assessment and contingency reversal conditions, in determining function of ADHD behavior and the effects of stimulant medication in regular classroom environments. Students diagnosed with ADHD participated in a double blind placebo controlled stimulant medication trial within this functional assessment. One of the four participants showed differential responding to stimulant medication during the descriptive conditions, suggesting an effect of the medication for this participant, and also showing the descriptive measures used can be sensitive to changes in behavior due to the presence of stimulant medication. Results from the brief FBA also showed the assessment procedures are sensitive enough to show differential responding to the medication as well as across manipulated environmental variables. Three of the four of the participants displayed higher rates of off-task behavior when peer attention was delivered contingent on off-task behavior. Two of the four participants displayed the lowest levels of off-task behavior during the contingency reversal conditions, regardless of medication. Overall, results indicated the usefulness of the functional assessment procedures in common classroom environments in determining function of behavior and efficacy of stimulant medication. This study also continued to support the trend of current research by detailing the importance of individual assessment of behavior and the effects of stimulant medication on the treatment of ADHD behavior.

Direct tests of the two models provided no support for either. When BPD symptoms were controlled for, ASPD and HPD symptoms were no longer related to each other or to impulsivity. Implications of this study and recommendations for future studies are discussed.

Show moreSuicide claims the lives of approximately 32,000 Americans each year. The interpersonal-psychological theory of suicide (IPTS; Joiner, 2005) was developed in an effort to clarify the nature of suicidality as well as to enhance risk assessment and prevention approaches. The IPTS differentiates between the desire for death by suicide and the capability for suicide, which is said to be acquired through repeated exposure to painful and provocative life events. Thus far, the relationship between painful and provocative events and the acquired capability for suicide has been repeatedly supported in independent samples (e.g., Van Orden et al.,2008; Bryan et al., 2010). To date, however, no research has investigated whether the path from pain and provocation to the acquired capability is uniform across populations. I sought to test whether individuals' experiences with negative affect might moderate this relationship, with individuals exhibiting greater difficulty managing emotional distress who report greater levels of lifetime pain and provocation demonstrating the highest levels of the acquired capability. Specifically, I examined negative urgency and distress tolerance as moderators. Results utilizing structural equation modeling indicated that the proposed models were not an adequate fit for the data; however, a post hoc series of hierarchical linear regressions revealed a number of significant interactions between emotion-based individual difference variables (negative urgency, distress tolerance) and pain and provocation in the prediction of the acquired capability for suicide. These significant interactions were not in the hypothesized direction, as greater levels of negative urgency and lower levels of distress tolerance dampened the relationship between painful and provocative events and the acquired capability for suicide. These results might indicate that, although emotionally dysregulated individuals exhibit a higher rate of death by suicide (e.g., Linehan, 1993), this is true despite their emotion dysregulation, not because of it. Experiencing discomfort as highly aversive may actually serve as a buffer against suicide and require that such individuals experience greater exposure to pain and provocation in order to habituate sufficiently to such stimuli.

The concept of impulsivity, however, fails to address the potential role of negative affect in such behaviors. The UPPS Impulsive Behavior Scale attempts to address this weakness by dividing impulsivity into four subscales: Urgency, Sensation Seeking, (lack of) Premeditation, and (lack of) Perseverance. I predicted that urgency, defined as the tendency to act rashly in response to the experience of negative affect, would be related to elevations on three maladaptive coping behaviors - excessive reassurance seeking, drinking to cope, and bulimic symptoms as measured by the Eating Disorder Inventory - in both cross-sectional and longitudinal analyses in an undergraduate sample (N=70). Participants were assessed at two time points, three to four weeks apart. Urgency significantly predicted all three outcome variables cross-sectionally at both Time 1 and Time 2. Time 1 urgency significantly predicted Time 2 excessive reassurance seeking. Changes in urgency from Time 1 to Time 2 predicted changes in all three outcome variables. Results indicate a cross-sectional relationship exists between urgency and certain maladaptive coping behaviors. Additionally, some form of longitudinal relationship appears to exist between these variables.

These behaviors also appear to decrease negative affect. Why is it, however, that individuals engage in these behaviors to reduce emotional distress rather than taking a shower or talking to a friend? This study proposes the role of emotional cascades, an emotional phenomenon that occurs when an individual intensely ruminates on negative affect, thus intensifying that negative affect to the point that an individual engages in a dysregulated behavior in order to distract from that rumination. The purpose of these studies was to examine the relationship between rumination and dysregulated behaviors, and in doing so determine if there is some support for the emotional cascade model. Using two different studies we were able to demonstrate that rumination is associated with some dysregulated behaviors, both cross-sectionally using structural equation modeling, and temporally using a two time-point method.

Show moreThe current study examined whether intrasexual competition for career success may contribute to body dissatisfaction and worse eating attitudes among achievement oriented college-aged women. In order to examine this aim participants viewed pictures of other women who varied in terms of weight and career success. Compared to participants low on status aspiration, participants high on status aspiration reported greater body dissatisfaction and ineffectiveness after being exposed to the thin, successful targets. However, status aspiring participants did not report greater drive for thinness, maturity fears, or bulimic symptoms. Hypotheses regarding the impact of weight status and success on perceptions of target career accomplishment and body size were supported. Specifically, thin, successful targets were rated as more accomplished in their careers than overweight, successful targets. Participants also judged successful, overweight targets to be thinner than unsuccessful, overweight targets. It is hoped that these findings will shed light on ways career women can pursue success without jeopardizing their health.

Title: Activity-Based Anorexia in Rats: Role of the Serotonergic System.
Creator: Atchley, Deann Penly, Eckel, Lisa, Levenson, Cathy, Berkley, Karen, Contreras, Robert, Joiner, Thomas, Department of Psychology, Florida State University
Abstract/Description: Activity-based anorexia (ABA), an animal model of anorexia nervosa in which rats are given free access to running wheels but restricted access to food, induces many symptoms of anorexia nervosa. This model has been used to examine biological factors that may contribute to the development of anorexia nervosa.

Show moreActivity-based anorexia (ABA), an animal model of anorexia nervosa in which rats are given free access to running wheels but restricted access to food, induces many symptoms of anorexia nervosa. This model has been used to examine biological factors that may contribute to the development of anorexia nervosa. Here, the role of the serotonin (5-HT) system in the development of ABA was examined in female rats. In Experiment 1, susceptibility to ABA was examined in rats treated with 8-OH-DPAT, a drug that reduces 5-HT neurotransmission. In this and subsequent experiments, rats had free access to running wheels, and food was restricted to 2 h/ day. Daily treatment with 8-OH-DPAT decreased wheel running and weight loss, suggesting that decreased 5-HT activity reduces susceptibility to ABA. In Experiment 2 we determined whether antagonism of the 5-HT2C receptor decreased susceptibility to ABA. Rats were subjected to the ABA paradigm as in Experiment 1 and treated daily with RS-102221, a selective 5-HT2C receptor antagonist. RS-102221 did not affect food intake or wheel running. However, RS-102221 treatment slowed weight loss, suggesting that antagonism of the 5-HT2C receptor decreases susceptibility to ABA. Because RS-102221 did not affect food intake and wheel running, some other mechanism, such as a change in thermoregulation, must mediate these results. In Experiment 3, neuronal activation in response to fenfluramine, a 5-HT agonist, was examined in rats with ABA. Rats were allowed to lose 0, 10, or 25% of their baseline body weight in the ABA paradigm. After reaching the weight loss criterion, rats were injected with fenfluramine or saline vehicle. Two h later, rats were perfused and brains were collected and processed for c-Fos-like immunoreactivity. Weight loss interacted with fenfluramine treatment to increase c-Fos expression in the nucleus of the solitary tract. Weight loss alone increased c-Fos expression in the arcuate nucleus, and fenfluramine treatment alone increased c-Fos expression in the central nucleus of the amygdala. This suggests that brain regions important in the control of energy balance are affected by exposure to the ABA paradigm. Taken together, these data suggest that 5-HT plays an important role in the development of ABA.

Abstract/Description: Recent studies have drawn a close relationship between visual perception and language, showing, for example, that readers respond faster to a picture of a flying eagle than a perched eagle after a sentence that implicitly constrains the eagle's shape (Zwaan, Stanfield, & Yaxley, 2002).

Show moreRecent studies have drawn a close relationship between visual perception and language, showing, for example, that readers respond faster to a picture of a flying eagle than a perched eagle after a sentence that implicitly constrains the eagle's shape (Zwaan, Stanfield, & Yaxley, 2002). The present experiments pursue an ecologically-stronger design, showing how incidentally acquired connections between perceptual and linguistic experiential traces in the cognitive network can automatically affect later language comprehension. Two phases were employed here: a phase exposing participants to pictures of critical objects and a later, ostensibly unrelated reading phase. Reading times in Experiment 1 and 2 were faster when the implied shape of objects in text passages matched the shape in first phase pictures. The introduction of an articulatory suppression task in the first phase of Experiment 3, however, produced no similar advantage for the match condition in the subsequent reading tasks. These results are explained as the effect of coding mismatches between phases as well as possible strategy differences between participants. Future directions of study are proposed to provide a clearer test of two competing models of language comprehension.

Show moreThe purpose of this study was to evaluate the predictive relationship of response styles (i.e., rumination and distraction) to depression and anxiety in children and to test the hypothesis that response styles explain the emergence of sex differences in depression in adolescence. Children in the 2nd through 7th grade completed questionnaires that measure response styles, depressive and anxious symptoms, and stressors. The reliability and validity of a response styles questionnaire, designed specifically for children, was established through multisample confirmatory factor analysis, and by examining the internal consistency, retest reliability, and convergent and divergent validity of the measure. The predictive association between response styles and depressive symptoms was examined and the diathesis–stress model was tested by examining the moderating effects of stress on the relationship between rumination and changes in depressive and anxious symptoms. Results revealed that rumination and distraction were positively and significantly correlated, suggesting that they are not orthogonal in nature. In addition, results revealed that rumination predicted both depressive and anxious symptoms, and that 6th/7th grade girls ruminated more than same aged boys. Stress did not moderate the relationship between response styles and anxiety. In contrast, the interaction between rumination and stress predicted later depression; however, the direction of the interaction was inconsistent with the prediction of the theory. Implications for the downward extension of response styles to children are discussed.

Show moreThis study sought to replicate and extend previous research that used affective modulation of the eye-blink startle response (STR) to explore the emotional consequences of drinking. One of four levels of alcohol dose (including a no-alcohol control) was administered to each of 101 (48 female) young social drinkers to evaluate the extent to which increasing blood-alcohol level (BAL) differentially influences reaction to visual stimuli that vary in their emotional content. The results indicate that increasing BAL was associated with a linear decrease in the overall STR reactivity. Alcohol intoxication did not significantly alter the stereotypic modulation of the affective valence dimension of emotional responding in the low BAL group (i.e. STR responding to pleasant images was attenuated and STR responding to unpleasant images was augmented in a similar fashion). However, it did have this effect in the moderate and high BAL groups, suggesting a possible threshold for the stress-response dampening effects of alcohol. STR, which is mediated by a neural circuit that involves input from subcortical regions of the nervous system, was contrasted with the concurrently measured postauricular reflex (PAR), which is mediated by a neural circuit that does not involve input from these areas, allowing for evaluation of the functional location of alcohol's effects on the arousal component of affective responding. The results indicate that while increasing BAL was associated with a decrease in overall STR magnitude, it was not associated with an overall decrease in PAR magnitude. This suggests the observed decrease in the arousal dimension of emotional responding is likely due to alcohol's effects on subcortical areas of the central nervous system (consonant with its effect on STR magnitude), rather than its effects on motor-output components of thenervous system (which would be associated with a decrease in PAR magnitude).

Show moreThe effect of alcohol on performance during single-feature and conjunctive-features visual search tasks was examined in 18 normal, young adult participants (nine women), using a counterbalanced, within-subjects design that examined performance under intoxicated (peak blood-alcohol concentration = 0.071 gms%) and sober (no-alcohol control) conditions. Behavioral responses, including reaction times and error rates for detection of targets were examined in the study's main analyses, as were patterns of eye-movement, including saccade velocity and amplitude, number and duration of fixations, inhibition of return, and functional field of view. The results of these analyses indicated that alcohol intoxication was not associated with increased reaction times or error rates on any searches. However, alcohol intoxication was associated with decreased numbers and increased durations of fixations on trials that involve searching for conjunctive-features targets or absent targets. Alcohol intoxication was also associated with decreased fixations on distracters during conjunctive-features searches and decreased re-fixations of search elements that they had previously visited. Finally, alcohol intoxication was associated with decreased amplitudes and velocities of saccades. In sum, these findings indicated that alcohol intoxication slowed the initiation of saccades and that this effect was most pronounced on conjunctive-features searches. The results also suggested that these delays appeared to allow participants to process more parafoveal information at each fixation than they would have when sober, thus producing more efficient processing despite reduced speed. This study provided little support for alcohol-related reductions in cognitive capacity or inhibitory control suggested by the attention allocation model (Josephs and Steele, 1990) and impaired control (Fillmore, 2003) theory, respectively, as key mechanisms underlying changes in visual search while intoxicated—at least not at the dose tested in the present study. However, there was evidence of a general slowing effect of alcohol intoxication on the initiation and velocity of eye movements, as well as alteration of their amplitudes, that appeared to enable individuals to perform visual search tasks without obvious impairment by gathering more information at each fixation and consequently reducing the number of unnecessary eye movements that they made. These results are largely consistent with those of other research that has used different oculomotor tasks to examine alcohol's effects on attention (e.g., Radach, et al., 2011). Together, this work suggests that alcohol might influence attention in visual search, not by impairing top-down, controlled processes that guide eye-movements, but rather by influencing the bottom-up, automatic processes that initiate them.

Show moreI proposed that burdensomeness expectancies are subtle concerns about bearing the burden of explanation on behalf of one's group that promote avoidance in interracial interactions. Two preliminary studies demonstrated that burdensomeness expectancies are a particular concern for Black/African American individuals and are related to avoidance of interracial contact. In Study 3, I examined whether burdensomeness expectancies could be alleviated and whether doing so would decrease Black participants' avoidance toward a White confederate. Participants viewed videos in which a White peer, with whom they expected to interact, expressed culturally sensitive or insensitive opinions. A control group saw a video in which the confederate did not discuss race. I assessed self-reported desire to avoid the interaction, avoidance-focused and approach-focused self-regulatory intentions, ratings of confederates, as well as participants' verbal and nonverbal approach-related behaviors in a video greeting they prepared. The manipulation failed to influence burdensomeness expectancies as intended and did not influence the dependent variables. Theoretical and methodological considerations for future work are discussed.

Show moreActivity-based anorexia (ABA) in an animal model of anorexia nervosa, in which rats are allowed free access to running wheels but only 2 h food access per day. Rats exposed to this paradigm display symptoms similar to those seen in anorexic women. These include decreased food intake, increased activity, rapid body weight loss, and estrous cycle disruptions. Despite that anorexia nervosa is more frequent in women than in men, ABA has been studied almost exclusively in male rats. In Experiment 1, development of, and recovery from, ABA was characterized in female rats with and without access to running wheels. Food intake, wheel running, body weight and phase of the estrous cycle were monitored daily prior to, during, and after a period of restricted feeding in which access to food was limited to 2 h/day. This study confirmed that access to wheels is necessary for the development of ABA in female rats, and that pre-adaptation to the wheels may accelerate the weight loss associated with ABA. Following food restriction, recovery of body weight was closely associated with resumption of estrous cycles. Despite pronounced hyperphagia during the recovery phase, rats displayed estrous-related decreases in food intake. These findings suggest that satiogenic signals that decrease food intake during estrus override the orexigenic signals that stimulate appetite following weight loss. Studies in humans suggest that the serotonergic system is involved in the etiology of anorexia nervosa. In Experiment 2, the effects of fenfluramine, a serotonin agonist, on the development of ABA was examined in female rats. Food intake, wheel running, body weight and phase of the estrous cycle were monitored daily prior to, during, and after a period of restricted feeding in which access to food was limited to 2 h/day. During the restricted feeding period, rats were i.p. injected with 0.50 mg/kg fenfluramine or saline daily. In addition, development of ABA in a saline-injected group that was pair-fed to the fenfluramine-injected group was examined. Fenfluramine treatment increased the development of ABA; rats treated with fenfluramine lost weight more rapidly, and displayed greater disruptions in estrous cyclicity, than control rats. Interestingly, a reduction in food intake, similar to that observed in fenfluramine-treated rats, failed to increase the development of ABA in pair-fed rats. This finding suggests that elevated serotonergic activity, rather than a suppression of food intake, is the critical factor that increased the development of ABA in this experiment. The mechanism underlying this effect is unknown; however, it is possible that the serotonergic system interacts with other systems involved in the control of food intake, such as neuropeptide Y(NPY), to increase susceptibility to ABA. Further research is necessary to determine how hypothalamic NPY concentration changes in response to fenfluramine treatment in rats with ABA.

Furthermore, the interactive model was tested to see if it showed specificity to bulimic, versus depressive or anxious, symptoms. Some support for the model's specificity to bulimic symptoms was observed; however, the increase of anxious symptoms was also observed. Clinical and theoretical implications are discussed.

Show moreThe present study investigates a possible causal model for the prediction of subjective well-being in Parkinson's disease (PD). The primary hypothesis proposed that, controlling for disease severity, validation-seeking attitudes among individuals with PD would predict less use of secondary control coping strategies, more relinquishing of control in the face of PD symptoms, lower psychosocial adjustment to PD, and lower subjective well-being. I also proposed that validation-seeking would indirectly contribute to lower adjustment to PD through the type of coping strategies used, as well as indirectly affect subjective well-being through both coping strategies and adjustment to PD (operationalized as fewer restrictions to work and social participation). First, the concept of relinquished control could not be investigated due to validity issues with the measure or the construct, so the results were limited to only secondary control coping efforts. Consistent with the hypotheses, validation-seeking attitudes did predict lower positive subjective well-being and better adjustment to PD predicted better overall subjective well-being (i.e., lower depressive symptoms and enhanced positive subjective well-being), controlling for all other variables. However, hypotheses regarding relationships between secondary control coping strategies and validation-seeking, adjustment to PD, and subjective well-being were not supported. Furthermore, exploratory analyses of these relationships suggested that, contrary to the hypothesis that secondary control coping would predict positive outcomes, the use of secondary control coping strategies predicted higher depressive symptoms and poorer adjustment to PD. Closer investigation of the secondary control coping measure suggests that individuals may not have distinguished between voluntary use of secondary control coping strategies and restrictions in activities that had to be made due to PD, especially when reporting changes in what they were doing as a result of PD.

Show moreThe purpose of this study was to determine if children's performance on rapid automatic naming (RAN) tasks served as a mediator in the relation between inattention and reading. Although previous studies have produced mixed results when examining the relation between naming performance and ADHD, ADHD has typically been defined using DSM IIIR or DSM IV criteria, which do not require individuals to evidence symptoms of inattention. This study expands the literature by focusing on inattention, the component of ADHD that has been shown to be most related to reading. Children from second to fourth grade classrooms completed two individual testing sessions which included assessment of their phonological awareness, naming (RAN-letters, RAN-digits, RAN-objects, RAN-colors), and reading ability. Inattention was assessed using both the Conners Continuous Performance Task (CPT; Conners, 2000) and parent ratings. Relations between inattention, naming, phonological awareness and reading were examined using correlation and hierarchical regression analyses. Consistent with previous research, performance on RAN-letters and RAN-digits, but not performance on RAN-objects and RAN-colors, was related to children's scores on reading measures. Although CPT performance was associated with phonological awareness in this study, neither performance on the CPT nor parent-ratings of attention was associated with children's performance on the RAN tasks. Consequently, the results of this study failed to find support for the hypothesis that naming performance mediates the relation between inattention and reading outcomes.

Show moreYears of research on various forms of goal setting interventions, specifically assigned versus participative, continue to yield inconclusive results. While many articles indicate that assigned goals produce results comparable to or even better than participative goals, others argue that even minute increases in employee satisfaction suggest that participation is worth any extra effort or time. Efficacy of classroom interventions developed to assist children with emotional handicaps is almost surely a result of how cleanly the interventions are applied. Token economies, with very specific reinforcement and correction procedures should be implemented with precision and consistency. In an attempt to increase the precision and consistency with which reinforcers, specifically prosocial points, were delivered by Instructional Aides, a further variation on goal setting was implemented. Classroom aides and the teachers to which they were assigned were formed into teams. These teams were given instruction in goal setting, and then asked to set collaborative goals, or goals that could be met with combined effort. Team members worked together to deliver prosocials in order to meet the goal they set together. Effects of collaborative goal setting were examined within a multiple baseline research design. Results indicate that increases in prosocial delivery were accomplished by all subjects. Supplementary measures indicate that improvements in prosocial delivery also made small improvements in student engagement in inappropriate behaviors. Finally, all subjects reported that collaborative goal setting was an intervention that they might use again, even for a different aspect of their jobs.

Show moreThis thesis aims to show a relationship between mental imagery and sensory perception through texts that prime change blindness between mental images and visual displays. In Experiment 1, participants read short texts depicting a visual scene. Following the text, one of three types of photographs was presented: a photograph representing the scene exactly (match), a photograph representing the scene with a change (mismatch), or a photograph representing an unrelated scene (filler). Participants judged whether the picture matched the preceding text. Three types of changes were presented: color, deletion, and addition. Mirroring results from studies in visual perception, subjects showed change blindness in comparing mental images with pictures, even though critical information from the original text was recognized with a high degree of accuracy. A text variable was also included to measure the effects of language and attentional focus on change detection: each text contained a final sentence with relevant or irrelevant information related to the changed aspect of the scene. Although there were no differences in accuracy of change detection, subjects were faster to detect changes with relevant texts than irrelevant texts. Experiment 2 served as a control for comparing types of change blindness in a conventional flicker paradigm without mental imagery. As a whole, these results mirror those within change blindness studies investigating visual perception—suggesting that focused attention is necessary in comparing mental images and pictures and that mental imagery is analogous to its corresponding perceptual mode.

Show moreIt has been well established that there is a great deal of individual variability in the response to drugs of abuse as well as to stressful life events. The overall aim of this dissertation is to simply ask what are the neurobiological mechanisms that may make some individuals more to prone to succumb to addictive properties of drugs of abuse, and how may stressful life events alter susceptibility? In humans, the personality trait of sensation seeking has been highly correlated to "risky" behaviors including drug taking. In rats, there exists an animal model of sensation seeking in which a population of outbred rats can be termed High Responders (HR), or Low Responders (LR), based on their exploration of a novel environment. Past research has demonstrated that this model has predictive validity in that HR animals are more likely to become behaviorally sensitized to, and self-administer drugs of abuse than LR rats. In the first aim of this dissertation we ask what changes in gene expression within the mesolimbic circuitry may occur as a result of behavioral sensitization. In this study, adult Sprague-Dawley rats were injected daily with amphetamine (1mg/kg, i.p.) or saline for 9 days followed by a challenge injection seven days later. Our results showed that HR rats, but not LR rats, developed behavioral sensitization to the locomotor activating effects of amphetamine. Furthermore, only HR rats pretreated with amphetamine exhibited an increase in dopamine transporter mRNA in the ventral tegmental area (VTA) and substantia nigra (SN). These results demonstrate the existence of individual differences in behavioral sensitization to amphetamine and suggest that the dopamine transporter may be a critical factor in the development and expression of behavioral sensitization to the locomotor activating effects of amphetamine. In the second aim of this dissertation, we sought to examine in the context of individual differences, if exposure to repeated psychosocial stress, social defeat in particular, would alter the locomotor stimulating effects of an acute injection (0.5, 1.0, and 1.5 mg/kg i.p.) of amphetamine. In an effort to understand what mechanisms underlie stress-induced sensitization to amphetamine, we examined long-term changes in striatal gene expression of the D1 and D2 receptors, as well as TH and DAT expression in the VTA and SN. Additionally, we examined if repeated social defeat stress led to an increase in corticosterone release in response to an acute injection of amphetamine. Finally, we investigated if repeated social defeat was associated with changes in dendritic spine density in the hippocampus, prefrontal cortex and nucleus accumbens of rats that exhibit stress-induced sensitization. Following repeated social defeat, LR rats and HR rats were behaviorally identical in response to acute injections of amphetamine. Furthermore, HR non-defeated rats had less D2 mRNA expression in the nucleus accumbens core and dorsal striatum than did LR non-defeated rats. However, after repeated social defeat, HR and LR rats had identical D2 mRNA expression in both the core and dorsal striatum. Additionally, we have shown that in comparison to non-defeated rats, there is an enhancement of corticosterone release in LR defeated but not HR defeated rats in response to an amphetamine injection. Finally, there were no changes in TH, D1 and DAT expression in any of the areas examined nor did social defeat stress induce a change in dendritic spine density in any of the brain areas examined in LR rats. One fascinating aspect of sensation seeking in humans is that despite similar hormonal responses during risk taking behaviors, these individuals report a lower level of anxiety in these situations when compared to non-sensation seekers. Interestingly, in rats, it has been demonstrated that some individuals will find the "stress" hormone, corticosterone, reinforcing. Specifically, it has been demonstrated that HR rats will self administer corticosterone at levels that mimic circulating plasma levels of corticosterone observed during mildly stressful events. Furthermore, in humans, chronic use of glucocorticoids has been reported to have euphoric effects in some individuals, but aversive effects in others. As such, in the final aim of this work, we asked if corticosterone itself has intrinsic rewarding properties. For these experiments we used a well established model of reward, termed conditioned place preference (CPP), in which a context is associated with the repeated pairing of a drug and subsequently tested to see if the chamber becomes preferred over the non-drug paired chamber. Here we report that corticosterone is not rewarding, nor is it aversive to rats. Furthermore, despite the reinforcing effects of corticosterone in HR rats, we observed no individual differences in the rewarding aspects of corticosterone.

Title: If I Can't Feel Your Pain, Then I Inflict Pain on You: Emotional Insensitivity as a Mechanism Underlying Aggressive Responses to Rejection.

Show moreThe current investigation sought to investigate whether emotional insensitivity (as opposed to emotional distress) mediates the relationship between social exclusion and aggressive behavior. Results from Experiments 1 and 2 showed that social exclusion caused decrements in emotional responsiveness, as indicated by reduced empathic concern toward another person's suffering. In both experiments, the reduction in emotional responsiveness mediated the link between social exclusion and aggressive behavior. Experiment 3 provided no evidence that the lack of emotional responsiveness toward one person following social exclusion had implications for aggression toward another person. These findings extend prior evidence that rejection causes the emotion system to cease functioning normally as a means of protecting the rejected person from a negative emotional experience. Being buffered from a negative emotional reaction can have negative consequences, however, in terms of weakening inhibitions that normally reduce aggression. Without a functioning emotion system, rejected participants were unable to feel empathic concern toward the victim of aggression and hence behaved aggressively.

The possibility that effortful control is comprised of multiple subordinate constructs can be presumed from extant research. The present study was conducted to determine whether tasks designed to measure effortful control can be described by hot (affectively salient) and cool (affectively neutral) dimensions, or is best understood as a single construct. Confirmatory factor analysis revealed that effortful control is best conceived of as unitary factor.

To further explain this relationship, this paper has explored the impact of the factors of functional health limitations and fluid intelligence on technology use and age. To do this, this paper used previous data collected by the Center for Research and Education on Aging and Technology Enhancement (CREATE) consisting of a sample of 1,204 adults over the age of 18. The participants completed a battery including self-rated health, technology experience, and measures of cognitive abilities, along with other measures that were not discussed in this paper. This study was conducted using data from the CREATE I data set and analyzed variables of age, fluid intelligence, functional health limitations, and technology use. The findings in this study show a significant positive interaction between age and functional health limitations on technology use, suggesting that technology use is impacted more among younger adults with functional health limitations than older adults with functional health limitations.

Show morePupil dilation (PD) has recently been reported as an index of activity in the locus coeruleus (LC), which is known to be integral to orienting processes, where adaptive gain theory and the LC-P3 hypothesis have been important to understanding the role of this activity in motivation (Nieuwenhuis et al., 2005; Nieuwenhuis et al., 2011). Separately, recent work in the study of gambling feedback has identified separable feedback negativity (FN) and reward positivity (RP) event-related potential (ERP) components that are sensitive to loss and gain outcomes, respectively (Bernat et al., 2011). While these two lines of research have advanced a considerable amount separately, the area investigating a possible relationship between LC functioning and higher cortical areas has been underdeveloped. In the current study, thirty-two participants completed a common gambling task while electrocortical signals and pupil diameter were measured to assess coordinated responding among cortical salience and control processes, and orienting processes. Results indicated that gain feedback produced significantly greater PD than loss, consistent with the view that LC phasic activation is driven by motivationally significant stimuli that signal cognitive reward (Nieuwenhuis et al., 2005). Also consistent with this view, ERP results revealed the RP component to most strongly predict PD, with RP activity in gains being a much stronger predictor of PD than RP in losses. Interestingly, RP activity during gains had a significant positive correlation with PD, while RP activity during losses had an equally significant negative correlation with PD. This means that more PD creates more of a disparity in RP activity between gains and losses, which supports the view that task engagement is a characteristic of exploitation, which is a mode of LC functioning (Aston-Jones & Cohen, 2005). These relationships show support for adaptive gain theory and the LC-P3 hypothesis, and suggest the possibility that cognitive reward and higher-level cortical areas may gate or modulate the orienting response according to task utility.

Show moreDepression is a debilitating disorder with established prevalence and detrimental impact on the economy. Ketamine is a fast acting and long lasting treatment for depression, including treatment resistant patients. The mechanism(s) behind ketamine's effects is unknown. Thus, this study assessed the effects of acute ketamine treatment on a new chronic stress paradigm using C57BL/6J and CD1 aggressor adult male mice. The C57BL/6J mice were assigned to three groups: emotional stress (ES), physical stress (PS), and control (CON) conditions. The mice in the PS condition received social defeats, while the ES mice witnessed the defeats, for 10 consecutive days, 10 minutes each day. Twenty-four hours after the last stress session, the mice were injected with either saline or ketamine (0.20 mg/kg) one hour before a social interactions test was conducted to assess whether ketamine could rescue deficits in interaction elicited by chronic stress. Mice in the PS condition showed significantly reduced interaction time when the target was present, whereas the ES-exposed mice displayed only similar trend, regardless of drug treatment. Time spent in corners varied as a function of stress exposure but not drug treatment, with the ES- and PS-exposed mice spending significantly more time in the corners when the target was present. With the exception of the ketamine-treated controls, mice receiving saline displayed reduced interaction times when compared to a group of non-injected controls regardless of stress condition. These finding suggest that ketamine was unable to alleviate the stress-induced deficits in social interaction, however, acute ketamine may be beneficial in alleviating the effects of acute stress.

Show moreEmbodied theories of language comprehension suggest that sentence comprehension involves a perceptual simulation of the objects, agents, and event described within the sentence using the same perception and action systems we use when we interact with the world. Past research shows that within experiments, the integratibility between the perceptual stimuli and cognitive representation influences reaction time to sensibility questions. This experiment was designed to investigate the question of whether embodied cognitive representations contain visual, semantic, and phonological properties and if some of these properties contribute to integratibility more than others. Participants listened to sentences describing the transfer of an object either towards or away from their body. They were then shown two pictures of an object that was either a visual, semantic or phonological competitor to the object described in the sentence. The two pictures of the competitor created an illusion of motion that either matched or mismatched the direction of motion described in the sentence. After viewing the two pictures, participants were asked a question to which their reaction time was recorded. A compatibility effect was said to have occurred if the reaction times for the match condition were faster than the mismatch condition.

Show moreExternalizing, a factor related to a deficit in impulse control, has been widely associated with reductions in the amplitude of the P300 event-related potential (ERP) component. Recently, time-frequency (TF) signal processing approaches have been able to index separable components underlying P300 activity, and provide incremental prediction for externalizing above traditional time-domain approaches to measuring P300 (Gilmore et al., 2010). Next, shared variance from time-domain measures of P300 from different tasks and the error-related negativity demonstrated incremental prediction for externalizing above single tasks (Nelson et al., 2010), consistent with the idea of a multivariate phenotype (Iacono, Carson, & Malone, 2000). The current study integrates these approaches by using TF analysis to extract multiple overlapping TF components from each task, and then apply factor analysis across the components from all the tasks to derive latent task-based brain activations. TF amplitude (TF-AMP) and inter-trial phase synchrony (TF-ITPS) measures were assessed. Results of the factor analysis suggested a two-factor solution, which corresponded to the well-known theta (3-7 Hz) and delta (0-3 Hz) frequency ranges in both measures. Solutions with a higher number of components were assessed as well, providing greater time and frequency detail to the solutions. Finally, the TF-AMP and TF-ITPS measures were assessed with regard to externalizing, and did evidence incremental prediction above traditional time-domain measures.

Show moreNicotine use during adolescence is associated with the development of many debilitating pathologies in adulthood such as anxiety and depression. Adolescence is a time of many social pressures and biological changes occurring within the brain and body. Therefore, studying the effects of nicotine exposure during adolescence on stress and subsequent sensitivity to nicotine itself is of great interest. To examine these questions I designed experiments to assess both short (i.e., 24 hours after treatment) and long-term (i.e., four weeks after treatment) behavioral consequences of nicotine (0.32 mg/kg) exposure during adolescence (i.e., postnatal days 35-49) in C57/BL6 male mice by exposing them to social-defeat stress, social interaction, and subsequent preference for nicotine. Nicotine-treated mice in the short-term condition displayed avoidant behaviors and a preference for the lowest concentration of nicotine (5 mg/l). Interestingly, the nicotine-treated mice in the long-term condition displayed enhanced social avoidance as well, with a similar preference for the low concentration of nicotine. These results indicate that exposure to nicotine during adolescence influences social interaction behavior and increases preference for nicotine, findings that last into adulthood. Future studies using different stressors and a complete nicotine dose-response may reveal further insight into how nicotine affects this age group and its long-lasting consequences. The work presented here increases our understanding of the effects of nicotine exposure during adolescents and the later effects, which may develop over time.

However, socially anxious individuals tend to see new social targets as sources of future exclusion and tend to withdraw from others after rejection. The current research tested the hypothesis that unlike their less socially anxious counterparts, people high in social anxiety would not become sensitive to cues of social affiliation following rejection. Findings showed that following rejection participants low in social anxiety demonstrated an ability to discriminate between genuine (Duchenne) and non-genuine smiles, whereas participants high in social anxiety did not demonstrate this ability. Further analyses suggested that high levels of social anxiety were associated with a biased tendency to categorize smiles as non-genuine.

When women become working mothers, their perceptions of warmth increase, but at the cost of reduced perceived competence, whereas men who become fathers gain perceived warmth, in addition to perceived competence (Cuddy, Fiske, & Glick, 2004). In this study, participates read a short description of a candidate for a server position for a restaurant and then viewed one of four pictures (a female shown alone, a female holding a baby, a male shown alone, a male shown holding a baby). Following this, participants rated the candidate on several traits related to warmth (warm, sincere, etc.) and competence (skillful, capable, etc.). It was hypothesized that the male holding the baby would be perceived as higher in warmth compared to the same man shown without the baby, but that his competence would be rated high regardless of the picture. It was also hypothesized that the female holding the child would be rated higher in warmth compared to the same woman shown alone. Finally, it was also expected that participants would rate the woman with the baby lower in perceived competence, compared to the woman alone. The results were mixed. The male target with the child was perceived as warmer compared to the same male shown alone and his competence ratings didn't change. This finding supported one of the hypotheses of the study. However, there were no differences observed the in female target's perceived warmth or competence in either of the picture manipulations.

Show moreDisordered eating is a serious problem affecting college women today. As technology advances and social networking sites become more heavily used, it is important to study the effects that sites like Facebook may have on college women's disordered eating attitudes and behaviors. This study aimed to analyze the relationship between Facebook use and disordered eating levels in college women through a correlational design and aimed to evaluate the momentary effects of Facebook use through an experimental design. This study hypothesized that higher Facebook use is positively correlated with higher levels of disordered eating and that social comparison, self-objectification and high self-monitoring account for these associations. To examine the correlation between Facebook use and disordered eating levels, this study collected data from a mass screening of participants in the psychology subject pool. To test whether use of Facebook causes momentary changes in mood, body image, and disordered eating urges, participants from the psychology subject pool were recruited for an experiment in which they were randomly assigned to either use Facebook or Wikipedia for 20 minutes and completed self-report assessments regarding current eating concerns, weight concerns, and mood before and after internet use. Results showed a positive and significant relationship between Facebook use and disordered eating and evidence that Facebook use contributes to maintenance of weight/shape preoccupation and anxiety. Results revealed a significant correlation between disordered eating, body comparison, trait anxiety and Facebook score. Future longitudinal research should examine Facebook use as a possible risk factor in the development of body image concerns and disordered eating.

Show moreIncreasing medication adherence in patients with epilepsy is important because, if taken properly, antiepileptic medication can reduce seizure frequency, and thus, improve quality of life and reduce hospital and emergency room visits. The goal of this study was to examine if non-professionals (undergraduates) can improve medication adherence among persons with epilepsy by implementing simple, but time-intensive interventions. Participants were eleven patients with epilepsy at a neurological clinic in Tallahassee that were referred by their neurologist based on his perception that their adherence was low and that they were favorable toward research. Study design was quasi-experimental in which each participant served as his or her own control. The first phase used a self-report diary in which baseline data was collected for at least one month to establish initial levels of adherence. Interventions included customized picture reminders, Didits (inexpensive device attached to side of medication container for keeping track of medication taking), and weekly phone calls that provided support and encouragement for taking one's medication. This study demonstrated that time-intensive interventions can be implemented by non-professionals, which can make interventions more widely available. Structured interviews suggested that the interventions were generally viewed positively by participants. However, due to difficulties with the self-report diary as the primary measure of adherence, we were not able to determine if the interventions actually improved participants' adherence. Future research should employ more objective measures of adherence, such as the Medication Event Monitoring System (MEMS) (See Paschal, Hawley, St. Romain, & Ablah, 2008 for review of measures).

Show moreWhat accounts for the stark changes in emotion, cognition, and behavior in women during the premenstrual phase of the menstrual cycle? I hypothesize that, in addition to the effects of hormones, a lack of self-control may account for these changes. The metabolically expensive activity of the premenstrual phase diverts energy from metabolically expensive self-regulatory processes, making the use of self-control more difficult. In this article, I experimentally test this hypothesis with the dual-task paradigm common to self-control research. That is, participants perform one task that requires and depletes self-control—the Stroop task—followed by another task that requires self-control—a dependent measure. I randomly assigned 34 undergraduate women to either a control or ego depletion condition and to participate either during the premenstrual or postmenstrual phase of their menstrual cycles. I measured total affect, critical thinking, and aggression. Results, while preliminary, are consistent with the hypothesis that self-control depletion is not only linked to emotional, cognitive, and behavioral changes in the premenstrual phase, but also exaggerates these changes. I offer an explanation for my findings and conclude with a discussion of future work and implications.

Show moreIn the face of a competitive marketplace, businesses are searching for effective solutions to managing employee work behavior. One such approach is through the systematic application of Organizational Behavior Management. While investigations of pay-for-performance programs and incentive systems have demonstrated desired changes in workplace behavior, little research has been conducted on the Performance Matrix, a measurement system and objective feedback tool. The current study offers insight on the construction and general effectiveness of the Performance Matrix when used in conjunction with a work-contingent incentive and feedback system for small groups. Primary research questions tested the efficacy of the Performance Matrix as a tool to change the customer service behaviors of 12 retail sales associates. Secondary questions pertained to manipulations of the prioritized weight distribution feature of the Performance Matrix, how it is used, effects on non-targeted behaviors and relation to response covariation, and assessment for preference and end-user satisfaction. Results indicated that customer service-type performance was changed on average by 10 percent when weight distribution differentials were 15 or more. No detrimental effects were found for other behaviors not targeted for incentive earnings. Implications for implementing a Performance Matrix system with incentives are discussed.
