The first is called continuous perception and the second categorical perception. Categorical perception (CP) can be inborn or can be induced by learning. Formerly thought to be peculiar to speech and color perception, CP turns out to be far more general, and may be related to how the neural networks in our brains detect the features that allow us to sort the things in the world into their proper categories, "warping" perceived similarities and differences so as to compress some things into the same category and separate others into different categories date: 2003 date_type: published publication: Encyclopedia of Cognitive Science volume: LXVII number: 4 publisher: MacMillan: Nature Publishing Group refereed: FALSE referencetext: Burns, E.
