Categorical perception effects induced by category learning.
The authors report a series of studies designed to determine whether effects similar to those observed in the innate categorical perception of color and phonemes are induced during the learning of simple unidimensional categories and more complex multidimensional ones. In Experiment 1 no evidence was found for such effects when stimuli varied on 1 dimension. Experiments 2 and 3 demonstrated a w...
متن کاملCategorical perception effects reflect differences in typicality on within-category trials.
Many studies have shown better discrimination of two stimuli that cross a category boundary than of two stimuli belonging to the same category. This finding, known as categorical perception, is generally assumed to reflect consistently good performance on cross-category trials, relative to within-category trials. However, Roberson, D., Damjanovic, L., and Pilling, M. (Memory & Cognition, 35, 18...
متن کاملCategorical effects in the perception of faces.
These studies suggest categorical perception effects may be much more general than has commonly been believed and can occur in apparently similar ways at dramatically different levels of processing. To test the nature of individual face representations, a linear continuum of "morphed" faces was generated between individual exemplars of familiar faces. In separate categorization, discrimination ...
متن کاملCategorical perception.
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 con...
متن کاملCategorical results do not imply categorical perception.
Categorical perception refers to the ability to discriminate betweenbut 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. The results are usually interpreted in terms of categorical, as opposed to continuous, perception of both speech and nonspeech c...
