Electrophysiologic responses to word/non-word CVC stimuli
Description:
The auditory P3 response is thought to be related to stimulus evaluation time. It is typically elicited using an "oddball tonal paradigm" in which "rare" acoustic events (tones) are embedded in a stream of "frequent" tonal signals. The... The purpose of this study was to determine if differences exist in the P3 response (latency and amplitude) elicited by tonal and speech signals during competing and non-competing stimulus conditions. P3 responses were obtained from 61... The addition of competing noise resulted in decreases in certain wavepeak amplitudes and increases in P3 latencies. The choice of stimulus (tones versus words) had no effect on wavepeak amplitude. However, P3 latencies were significantly...
