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.

Phi Phenomenon
Perception
16. The optic nerve is made up of...
Continuation
Ganglion cells
After light passes through receptors
Visual Pathway
17. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.
After light passes through receptors
Purkinje shift
Cornea
Fovea
18. The chemical that aids the receptor cells in transduction
Size Constancy
Phi Phenomenon
Optic Chasm
Photopigments
19. Or overlap of objects shows which objects are closer
interposition
Proximity
Ponzo Illusion
Differential Threshold
20. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing
Symmetry
Structuralist Theory
Opponent Color or Opponent Process Theory
binoculary disparity
21. Comes from the complexity of the sound wave
Timbre
Gestalt Psychology
Nativist Theory
Frequency
22. Consists of one optic nerve connection each eye to the brain.
Figure-Ground Reversal Patterns (illusion)
Visual Pathway
Frequency
Optic Chasm
23. 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
Purkinje shift
Moon Illusion
Symmetry
Receiver operating characteristic
24. He tendency to group together items that are near each other
Outer ear
Proximity
Ganglion cells
Purkinje shift
25. The physical intensity of light

Perception
Moon Illusion
Closure
binoculary disparity
27. humans best hear at

Closure
Robert Frantz

28. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.

Ewald Hering
Eleanor Gibson and Richard Walk
Optic Chasm
31. Famous for the theory of color blindness
Outer ear

32. 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
33. Is the result of regeneration of retinal pigment

34. Objects that have been drawn and can be perceived but are geometrically impossible

36. Takes place when receptors for a particular sense detect a stimulus.

37. 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.
Thomas Young and Hermann von Hemholtz
