The electromagnetic spectrum consists of all the following:
[ ] visible light.
[ ] micro-waves.
[ ] x-rays.
[ ] infra-red radiation.
The "Principle of Univariance" states that;
Photoreceptor responses vary only along one dimension
F a species has evolved two cone types, then the second more recently acquired type of cone is typically;

Adding more than one cone type to the photoreceptor mosaic can;
A short wavelength cone (blue).


compromise the ability to discern fine details.
Chromatic aberration refers to the fact that;
An optical system cannot simultaneously focus light of different wavelengths.
Experts on the evolution of color vision such as Mollon propose that the development of trichromatic color perception made it possible for organisms to discriminate;
Red from green.
In humans, the outputs of the three cone types are compared in different ways to create "opponent" channels which transmit all of the following EXCEPT;
Absolute wavelength detection/discrimination.
The "psychological" primary colors identified by Hering do not include;
Orange
Koniocellular retinal ganglion cells are not;
Found only in primates.
A person who lacks just one of the normal compliment of cone photopigments would not be
called;
A protoanope
To achieve color constancy, the visual system appears to;
Compare the responses of different color channels across large areas of the visual field.
Neurons demonstrating color constancy activity are first found in;
V4
If you fixate on a red patch for several seconds, then move your gaze to a light gray surface, you will see a __________ patch. This is an example of __________ afterimage.
Green : negative
An observer who is unable to discriminate certain pairs of stimuli from one another which differ
only in their wavelength composition might be;
[ ] suffering from achromatopsia.
[ ] a normal trichromat.
[ ] a deuteranope.
The receptive field encoding for the exclusively color sensitive neurons in visual cortex is;
Concentric double-opponent RF's.
Mixing blue and yellow paint together to make green is an example of;
