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.

Current thinking about sensation and perception
16. 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.

Constancy
17. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz

20. Is the result of regeneration of retinal pigment
Phi Phenomenon
Dark adaptation
Figure-Ground Reversal Patterns (illusion)

21. 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.
Muller-Lyer Illusion
Hue
Gestat Ideas
David Hubel and Torsten Wiesel
22. 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
