Categorical Perception of Familiar Objects [PDF]

open access: yesCognition, 2002
We report three experiments where the categorical perception of familiar, three-dimensional objects was investigated. A continuum of shape change between 15 pairs of objects was created and the images along the continuum were used as stimuli. In Experiment 1 participants were first required to discriminate pairs of images of objects that lay along the ...

Categorical Results Do Not Imply Categorical Perception [PDF]

open access: yesPerception & Psychophysics, 1982
Categorical perception refers to the ability to discriminate between- but not within-category differences along a stimulus continuum. Although categorical perception was thought to be unique to speech, recent studies have yielded similar results with nonspeech continua.

Categorical perception

WIREs Cognitive Science, 2009
AbstractCategorical perception (CP) is the phenomenon by which the categories possessed by an observer influences the observers' perception. Experimentally, CP is revealed when an observer's ability to make perceptual discriminations between things is better when those things belong to different categories rather than the same category, controlling for

Categorical Perception of Race

Perception, 2002
Traditionally, 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 ...

The ABCs of categorical perception

Cognitive Psychology, 1986
Abstract 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 ...

The End of Categorical Perception as We Know It [PDF]

open access: yesSpeech Communication, 2003
Comparing phoneme classification and discrimination (or “categorical perception”) of a stimulus continuum has for a long time been regarded as a useful method for investigating the storage and retrieval of phoneme categories in long-term memory.
