.
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.

2. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.

15. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.
Optic Chasm
texture gradient
Moon Illusion
Ewald Hering
16. 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.

Vision
Timbre
Perception
22. The clear protective coating on the outside of the eye

23. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.

24. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward

Miss
Mental set
25. Developed the visual cliff to study whether depth perception was innate

Constancy
False alarm
26. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear
Gestalt Psychology
Cornea
Terminal Threshold
Size Constancy
27. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes
Figure-Ground Reversal Patterns (illusion)

Visual Acuity
28. Refers to how we see texture or fine detail differently from different distances
