Significats de categorical perception en anglès

Psychophysical and cognitive aspects of categorical perception: A critical overview.

Four experiments probed the nature of categorical perception (CP) for facial expressions.

The conditions under which categorical perception (CP) occurs for unfamiliar faces are unclear.

Robust findings show that categorical perception (CP) occurs in identification of familiar faces.

At least for the domain of color, categorical perception appears to be a categorical, but not a perceptual phenomenon.

These results provide no support for the view that categorical perception is associated with increased perceptual sensitivity at category boundaries.

This finding, known as categorical perception, is generally assumed to reflect consistently good performance on cross-category trials, relative to within-category trials.

However, sensitivity to subtle changes of identity was found in previous studies using unfamiliar faces, for which categorical perception is less pronounced.

This grouping operation underlies the phenomenon of categorical perception (CP)-the experience of perceiving discrete categories rather than gradual variations in signal input.

Moreover, Categorical Perception effects were found to differ even between languages with broadly similar color categories.

Categorical Perception effects for both English and Berinmo were found, but only at the boundaries of existing linguistic categories.
