.
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.

17. 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.
There are fewer cones per ganglion cells
Receptor Cells
Gestalt Psychology
Light
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.
Timbre
Perception
interposition
Lateral Inhibition
19. 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.

20. The chemical that aids the receptor cells in transduction
J.A. Swet'S Theory of Single Detection (TSD)

Hermann Von Hemholtz
Autokinetic effect
Correct Rejection
22. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance
Optic Chasm
Receptor Cells
Ciliary Muscles
Linear perspective
23. Asserts that perception and cognition are largely innate
Timbre
Vision
Differential Threshold
Nativist Theory
24. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
Symmetry
Hit
Response Bias
Color constancy
25. Found that infants prefer relatively complex and sensational displays
texture gradient
Visual Pathway
Robert Frantz
Depth perception
26. 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.

Cones
Linear perspective
29. 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.
Structuralist Theory
Hue
Eleanor Gibson and Richard Walk
Opponent Color or Opponent Process Theory
