Categorical 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 the physical difference between the things. We consider several core questions related to CP: Is it caused by innate and/or learned categories, how…

The mechanism of color category perception: Effects of language
: Categorical perception (CP) effect indicates that people are faster and more accurately at discriminating between two colors from different categories than two colors from the same category, even
Relating categorization to set summary statistics perception
TLDR
This work relates category prototype to set mean and same/different category to in/out-of-range elements, defining a direct parallel between low-level set perception and high-level categorization.
Categorization Difficulty Increases Categorical Perception
We created an online category-learning experiment in which subjects (Ss) were trained by trial and error with corrective feedback to recognize and categorize two different kinds of computer-generated
Categorical face perception in fish: How a fish brain warps reality to dissociate “same” from “different”
TLDR
The results reveal how perception can be influenced in a top‐down manner even in the absence of a visual cortex.
No matter how: Top-down effects of verbal and semantic category knowledge on early visual perception
TLDR
The findings support cognitive penetrability of perception, with linguistic categories informing perceptual predictions down to the processing of low-level visual features.
The Irrationality of Categorical Perception
TLDR
Across both visual and auditory decision tasks, observers consistently placed too much weight on perceptual uncertainty relative to action uncertainty, indicating that normative decision making may be fundamentally constrained by the architecture of the perceptual system.
Categorical Perception Beyond the Basic Level: The Case of Warm and Cool Colors
TLDR
The findings show that categorical distinctions beyond the basic-level repertoire of one's native language are psychologically salient and may be spontaneously accessed during normal perceptual processing.

TLDR
The present model highlights how conscious and non-conscious decisions may correspond to distinct categorizations of the same stimulus encoded by a high-dimensional neuronal population vector.

Acquisition of categorical color perception: a perceptual learning approach to the linguistic relativity hypothesis.
TLDR
Evidence is provided that supports the possibility of learned categorical perception (CP) and the data are consistent with the possibility that language may shape color perception and suggest a plausible mechanism for the linguistic relativity hypothesis.

Visual categorization shapes feature selectivity in the primate temporal cortex
TLDR
This work shows that feature selectivity in the macaque inferior temporal cortex is shaped by categorization of objects on the basis of their visual features, and finds enhanced neuronal representation of the diagnostic features relative to the non-diagnostic ones.
Interactions Between Perceptual and Conceptual Learning
TLDR
This chapter reviews theoretical and empirical evidence that perceptual vocabularies used to describe visual objects are flexibly adapted to the demands of their user and extends arguments made elsewhere for adaptive perceptual representations, and describes computer simulations that provide accounts of these interactions using neural network models.
Lateralization of categorical perception of color changes with color term acquisition
TLDR
It is shown that the RH to LH switch in color CP occurs when the words that distinguish the relevant category boundary are learned, and the findings suggest that lateralization of color CP changes with color term acquisition.
Influences of categorization on perceptual discrimination.
TLDR
Four experiments investigated the influence of categorization training on perceptual discrimination and the relevance of the results for theories of perceptual learning, dimensional attention, categorical perception, and categorization are discussed.
