.
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.

21. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.

22. Has monocular and binocular cues

24. The way that a single point of light viewed in darkness will appear to shake or move. the reason for this is the movement of our own eyes
Ambiguous Figures (illusion)
Closure
Autokinetic effect
interposition
25. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.
26. Refers to how we see texture or fine detail differently from different distances
