.
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.

Differential Threshold
16. Is composed of photons and waves measured by brightness and wavelengths

After light passes through receptors
21. The chemical that aids the receptor cells in transduction

22. 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
Amplitude
Constancy
Thomas Young and Hermann von Hemholtz
23. 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.
Minimum principle
Phi Phenomenon
Correct Rejection
Constancy
24. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.

26. The overarching Gestalt idea that experience will be organized as meaningful - symmetrical - and simple whenever possible.
Pragnanz

1000hz
Thomas Young and Hermann von Hemholtz
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
