colour and motion

Question 1

what is colour dictated by

Answer 1

surface reflectance

Question 2

what is colour transduction

Answer 2

the valley of cones have 3 varieties [trichromatic vision], the combination of their responses to light waves determines colour perception

Question 3

what is colour constancy

Answer 3

our brains perception discounts variance in illumination, focusing only on the objects reflectance so that colour perception doesn’t change

Question 4

chromatic adaptation

Answer 4

reduces our sensitivity to the dominant wavelengths in the light within certain environments [allows colour constancy]

Question 5

space/position constancy

Answer 5

we factor out the effects of our own eye movement [2-3 times per second] so that the world stays stable

Question 6

how does space/position constancy work

Answer 6

by monitoring our own intentions of movement [top down] factor out motor commands
