How is categorical perception involved in the emergence of the knowledge of colours of things?
Categorical perception provides ‘the building blocks—the elementary units—for higher-order categories’
Harnad, 1987 p. 3
‘The building blocks of all our complex representations are the representations that are constructed from individual core knowledge systems.’
Spelke, 2003: 307
View 1 : Having categorical perception of colour (or X) amounts to having colour (or X) concepts.
‘The module … automatically provides a conceptual identification of its input for central thought … in exactly the right format for inferential processes’

Acquiring colour concepts depends on acquiring colour words.
‘the course of acquisition for color is protracted and errorful’
Sandhofer and Thom, 2006

The extensions of colour terms vary between languages.
(E.g. Russian colour terms include ‘goluboy’ (for lighter blues) and ‘siniy’ (for darker blues).)

Infants’ and toddlers’ perceptual categories are not influenced by the extensions of colour terms.
Franklin et al, 2005
Therefore:
Infants’ perceptual categories do not match adults’ concepts.
