.
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. The center of the retina; has the greatest visual acuity

3. 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

9. 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.
Gestalt Psychology
Purkinje shift
Depth perception
Ganglion cells
10. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision

Striate cortex to the visual association areas of the cortex
11. Objects that have been drawn and can be perceived but are geometrically impossible
After light passes through receptors

Response Bias
Impossible Objects
12. Why do cones see better than rods?
Light
Optic Chasm
Ewald Hering
There are fewer cones per ganglion cells
13. 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
14. 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.
Current thinking about sensation and perception
Optic Chasm
Fovea
Ewald Hering
15. 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.
E.H. Weber
Constancy
Visual Pathway
Vision
16. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'
Visual Cliff
Dark adaptation
Outer ear
Impossible Objects
17. Asserts that perception and cognition are largely innate
Hit
Nativist Theory
Moon Illusion
Symmetry
18. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl
Middle ear
Eleanor Gibson and Richard Walk
Ponzo Illusion
Correct Rejection
19. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward
Ponzo Illusion
Timbre
Thomas Young and Hermann von Hemholtz
Closure
20. Proposed the perceptual development and optic array
Continuation
Miss
James Gibson
Neural Pathways
21. Famous for the theory of color blindness
Hermann Von Hemholtz
Size Constancy
McCollough Effect
Amplitude
22. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green
Ewald Hering
3 steps involving sensation
Prosopagnosia
Tri-color Theory (component theory)
23. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina
Terminal Threshold
Robert Frantz
Ciliary Muscles
Depth perception
24. Refers to how we see texture or fine detail differently from different distances
Color constancy
texture gradient
Phi Phenomenon
Differential Threshold
25. 1. Reception 2. Sensory Transduction 3. Neural Pathways
3 steps involving sensation
Outer ear
Minimum principle
Ganglion cells
26. 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.

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