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;
|
Subtractive color mixing.
