.
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.

20. Rods and cones on the retina that are responsible for sensory transduction.
Outer ear

21. The tendency to perceive a smooth motion. This explains why motion is perceived when there is none - often by the use of flashing lights or rapidly shown still-fram pictures - such as in the perception of cartoons. This is apparent motion
texture gradient

Phi Phenomenon
Sensation
22. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing
Response Bias
Miss
Continuation
Structuralist Theory
23. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina
Thomas Young and Hermann von Hemholtz
The visual pathway
Tri-color Theory (component theory)

Rods
The visual pathway
26. Is the tendency to complete incomplete figures
Perceptual Development
E.H. Weber
Closure
Weber'S Law
27. 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.
