Colour perception changes with basic colour word comprehension [PDF]

open access: yesDevelopmental Science, 2023
AbstractRecent work has investigated the origin of infant colour categories, showing pre‐linguistic infants categorise colour even in the absence of colour words. These infant categories are similar but not identical to adult categories, giving rise to an important question about how infant colour perception changes with the learning of colour words ...

Conflict between background matching and social signalling in a colour-changing freshwater fish [PDF]

open access: yes, 2016
The ability to change coloration allows animals to modify their patterning to suit a specific function. Many freshwater fishes, for example, can appear cryptic by altering the dispersion of melanin pigment in the skin to match the visual background ...

The Stiles-Crawford colour change [PDF]

open access: yesVision Research, 1974
Abstract To obtain the Stiles-Crawford colour change, the absorption of guided and unguided light by a cone outer segment as a function of the angle of incidence is estimated. The model is specified in two ways: the HE 1,1 model, based on a waveguide modal analysis, and the geometrical optics model.
