Exam 6: Color Perception

What is the difference between additive and subtractive color mixing?

Additive color mixing is the creation of a new color by a process that adds one set of wavelengths to another set of wavelengths.

The principle whereby any single cone system is colorblind, in the sense that different combinations of wavelength and intensity can result in the same response from the cone system, is known as ______.

Color mixing in which a new color is made by the removal of wavelengths from a light with a broad spectrum of wavelengths is known as ______.

Double-opponent cells are thought to be particularly useful for detecting ______.

What theory proposes that all colors on the color circle can be represented by the following pairs of opposing mechanisms: blue-yellow, red-green, and black-white?

A psychophysical color match between two patches of light that have different sets of wavelengths is known as ______.

Gabriele Jordan and her colleagues in England have shown that at least some women with 4-cone systems in their retinae are ______.

Double-opponent cells are ______.

A lack of S-cones is known as ______.

If you stare at a bright incandescent light bulb for even a short time and then close your eyes, you will continue to see an afterimage of that light bulb for a relatively brief period.But you will notice that even though the light bulb has a yellowish hue, your afterimage will appear somewhat blue.This phenomenon supports the ______ theory of color vision?

Which of the following is the least common of the cones that are found in the retinae?

Which of the following is a statement that relates to the principle of lightness?

A light of 485 nm is presented to a person's visual system.Which of the following is the best description of what happens next?

Which of the following is a more saturated/less saturated pair of colors?

When we use color names such as red, orange, green, and indigo, we are referring to ______.

What primarily differentiates the three types of cone photoreceptors in the retina?

Colors that are associated with particular wavelengths are called ______ colors.

Cone-opponent cells are found in the lateral-geniculate nucleus, but color-opponent cells are found in V1 of the cerebral cortex.

Neurons that respond best when they are excited by the input from one cone type in the center, but inhibited by the input from another cone type in the surround, are known as ______ cells.
