Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

20. Also known as color - is the dominant wavelength of light
Moon Illusion
Hue
Ciliary Muscles
Terminal Threshold
21. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.
Visual Pathway
Opponent Color or Opponent Process Theory
Structuralist Theory
Miss
22. Is knowing the color of an object even with tinted glasses on
Prosopagnosia
Differential Threshold
Optic Chasm
Color constancy
23. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

24. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright

Phi Phenomenon
26. Developed the visual cliff to study whether depth perception was innate
Eleanor Gibson and Richard Walk
Muller-Lyer Illusion
False alarm
Visual Field
27. Discovered that cells in the visual cortex were so complex and specialized that they respond to certain types of stimuli. For example - some cells only respond to vertical lines - whereas some respond to only right angles.

David Hubel and Torsten Wiesel
Reception
Cones
28. Saying you detect a stimulus that is not there
False alarm
Striate cortex to the visual association areas of the cortex
Purkinje shift
Mental set
29. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou
