.
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.
1. 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.

2. Is knowing the color of an object even with tinted glasses on
apparent size

12. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.
Ewald Hering

Lens
Constancy
13. 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
Middle ear
Purkinje shift
After light passes through receptors
Terminal Threshold
14. How people perceive objects in the way that they are familiar with them - regardless of changes in the actual retinal image. A book - for example - is perceived as rectangular in shape no matter what angle it is seen from.
Ganglion cells
Continuation
Constancy
Lateral Inhibition
15. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc

Inner ear
Ciliary Muscles
16. Correctly sensing a stimulus
Hit
Inner ear
Proximity
Ewald Hering
17. Failing to detect a present stimulus
Minimum principle
Inner ear
Constancy
Miss
18. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.
Depth perception
1000hz
Lateral Inhibition
Frequency
19. Refers to how we see texture or fine detail differently from different distances
Receptor Cells
Frequency
Striate cortex to the visual association areas of the cortex
texture gradient
20. Gives us clues about how far away an object is if we know about how big the object should be
McCollough Effect
Neural Pathways
apparent size
Brightness
21. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.
Hit
Sensation
Gestalt Psychology

Symmetry
Miss
24. Is composed of photons and waves measured by brightness and wavelengths
Optic Chasm
Visual Field
Visual Cliff
Light
25. Comes from the complexity of the sound wave
Thomas Young and Hermann von Hemholtz
Neural Pathways
Timbre
Ambiguous Figures (illusion)
26. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.
motion parallax
Proximity
Perceptual Development
After light passes through receptors
27. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle

28. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance
J.A. Swet'S Theory of Single Detection (TSD)
Ponzo Illusion
Linear perspective
McCollough Effect
29. 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.
