Categorical Perception of Race
Perception, 2002Traditionally, research demonstrating categorical perception (CP) has assumed that CP occurs only in cases where natural continua are divided categorically by long-term learning or innate perceptual programming. More recent research suggests that this may not be true, and that even novel continua between novel stimuli such as unfamiliar faces can show

Modeling phoneme perception. I: Categorical perception
The Journal of the Acoustical Society of America, 1992On the basis of a number of vowel and stop-consonant discrimination experiments (AX and 2IFC fixed and roving) with natural stimuli, it is concluded that stop-consonant perception is highly categorical: there were few significant differences between the discrimination results and the phoneme identification results.

Social cognition: Categorical person perception
British Journal of Psychology, 2001In attempting to make sense of others, perceivers regularly construct and use categorical representations (e.g. stereotypes) to streamline the person perception process. A debate that has dominated recent theorizing about the nature and function of these representations concerns the conditions under which they are activated in everyday life.

The ABCs of categorical perception
Cognitive Psychology, 1986Abstract Studies of speech perception first revealed a surprising discontinuity in the way in which stimulus values on a physical continuum are perceived. Data which demonstrate the effect in nonspeech modes have challenged the contention that categorical perception is a hallmark of the speech mode, but the psychophysical models that have been ...

Categorical perception of facial expressions
Cognition, 1992People universally recognize facial expressions of happiness, sadness, fear, anger, disgust, and perhaps, surprise, suggesting a perceptual mechanism tuned to the facial configuration displaying each emotion. Sets of drawings were generated by computer, each consisting of a series of faces differing by constant physical amounts, running from one ...

Categorical relations in shape perception
Spatial Vision, 1996Many researchers have proposed that objects are perceived as structural descriptions, which specify the configuration of an object's features (or parts) in terms of their categorical relations to one another. Others have proposed that objects are perceived as views, which specify the configuration of an object's features in terms of their coordinates ...

Categorical Speech Perception in Cerebellar Disorders
Brain and Language, 1997Keele and Ivry (1991) considered the cerebellum an "internal clock" responsible for temporal computations both in the motor and in the perceptual domain. These authors, therefore, expected that the processing of durational parameters of the perceived acoustic speech signal such as voice onset time (VOT) depends upon the cerebellum as well.

“Categorical Perception” and Linguistic Categorization of Color
Review of Philosophy and Psychology, 2015This paper offers a conceptual clarification of the phenomenon commonly referred to as categorical perception of color, both in adults and in infants. First, I argue against the common notion of categorical perception as involving a distortion of the perceptual color space. The effects observed in the categorical perception research concern categorical

Categorical perception (CP) occurs when discrimination of items that cross category boundaries is faster or more accurate than discrimination of exemplars from the same category. Categorical perception of color is observed when, for example, a green stimulus and a blue stimulus are more easily distinguished than two stimuli from the same color category
