Categorical perception refers to the enhanced discernibility of stimuli that exist in different innate or learned categories. This effect has been observed in many different contexts, ranging from speech phoneme differentiation (Liberman et al, 1957) to distinguishing between simple shapes (Goldstone, 1994). While evidence for categorical perception has been found for many different types of stimuli, experiments have given mixed results regarding the existence of CP in complex (non-face) shapes. Some research found no evidence for categorical perception of complex shapes. Instead, global acquired distinctiveness, or an enhanced ability to detect dimensionally relevant differences regardless of category, was determined to be present (Folstein, Palmeri and Gauthier, 2014). This study attempted to find evidence of categorical perception in complex objects by using a variation of an experimental setup utilized by Goldstone in 1994. Subjects completed both a category learning exercise and object discrimination task within a single one-and-a-half-hour session. While no evidence for categorical perception was discovered, the amount of time participants had to learn the categories may have prevented the effect from being observed.
