Instructions:
Answer 50 questions in 15 minutes.
If you are not ready to take this test, you can

.
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.

11. Why do cones see better than rods?
Weber'S Law
Retina
Minimum principle
There are fewer cones per ganglion cells
12. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

19. Famous for the theory of color blindness
Depth perception
Visual Pathway
Hermann Von Hemholtz
Optic Array
20. Consists of the bony labyrinth - a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: The cochlea - dedicated to hearing; converting sound pressure patterns from the outer ear into electroc
Inner ear
Amplitude
Visual Field
motion parallax
21. The moon looks larger when we see it on the horizon than when we see it in the sky. This is because the horizon contains visual cues that make the moon seem more distant than the overhead sky.
J.A. Swet'S Theory of Single Detection (TSD)
Optic Array
Moon Illusion

22. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward

24. Is knowing the color of an object even with tinted glasses on
Hit
Gestalt Psychology
