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.

Minimum principle
15. How we organize or experience sensations
Prosopagnosia

18. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward
interposition
Rods
Ponzo Illusion
Correct Rejection
19. Applies to all senses but only to a limited range of intensities. The law states that a stimulus needs to be increased by a constant fraction of its original value in order to be noticeably different

20. Found that infants prefer relatively complex and sensational displays
Nativist Theory
Depth perception
Robert Frantz
Prosopagnosia
21. Best at seeing fine details
Muller-Lyer Illusion
apparent size
Cornea
Visual Acuity
22. 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
Fechner'S Law
Phi Phenomenon
Ponzo Illusion
Hermann Von Hemholtz
23. 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.
David Hubel and Torsten Wiesel
Neural Pathways
Figure and ground relationship
Inner ear
24. A theory for color vision. It suggests that two types of color sensitive cells exist: Cones that respond to blue-yellow colors and cones that respond to red-green. When one color of the cone is stimulated - the other is inhibited.
Perception
Opponent Color or Opponent Process Theory
Ewald Hering
Absolute threshold
25. The physical intensity of light
Cornea
Visual Acuity
Brightness
Rods
26. Allows the eyes to see contrast and prevents repetitive information from being sent to the brain. Once the receptor cell is stimulated - the others nearby are inhibited.
Color constancy
texture gradient
Lateral Inhibition
apparent size
27. Located by the cornea
The visual pathway
Constancy
Lens
Terminal Threshold
28. The chemical that aids the receptor cells in transduction
Photopigments
Thomas Young and Hermann von Hemholtz
Fovea
Correct Rejection
29. Proposed the perceptual development and optic array
Perceptual Development
Constancy
James Gibson
1000hz
30. Why do cones see better than rods?
There are fewer cones per ganglion cells
Receiver operating characteristic
Differential Threshold
Optic Chasm
31. Is knowing the color of an object even with tinted glasses on
Brightness
Color constancy
Ciliary Muscles
Gestalt Psychology
32. Has been called the most important depth cue. Our eyes view objects from two slightly different angles - which allows us to create a 3-dimensional figure
Fechner'S Law
3 steps involving sensation
Depth perception
binoculary disparity
33. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

34. 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.
