.
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.

25. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
Ponzo Illusion
Nativist Theory
Optic Chasm
Response Bias
26. The part of the world that triggers a particular neuron
Receptive Field
Light
Vision
Constancy
27. 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

Size Constancy
Differential Threshold
Optic Array
