Perceiving tomatoes as consistently red, despite shifting illumination, is an example of what? form perception, perceptual constancy, retinal disparity, or grouping.
00:14
So perception is a big trick that brain plays, because what you actually receive, the visual information you receive, is a 2d canvas.
00:24
And that 2d canvas has retinal disparity.
00:26
So you have two images, one from each eye, that are subtly different.
00:32
And the brain makes up a map of perception from it.
00:36
And so these are different ways that that perception is altered by the brain.
00:41
For example, retinal disparity, as i've said, is where the two images are slightly different, and the brain merges them into one.
00:51
So that's not all we're looking at here.

We're seeing colour that stays the same...
