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

2. humans best hear at
1000hz

3. Gives us clues about how far away an object is if we know about how big the object should be

5. Is the inability to recognize faces

13. Defined the Just Noticeable Difference

Light
binoculary disparity
Symmetry
15. The clear protective coating on the outside of the eye
E.H. Weber
Cornea
Autokinetic effect
Visual Acuity
16. 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.
Proximity
J.A. Swet'S Theory of Single Detection (TSD)
Lateral Inhibition
Thomas Young and Hermann von Hemholtz
17. Located by the cornea
Optic Chasm
Autokinetic effect
Lens
Ciliary Muscles
18. 1. closure 2. Proximity 3. Continuation or good continuation 4. Symmetry 5. Constancy 6. Minimum principle
Gestat Ideas
Outer ear
Dark adaptation
Inner ear
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. The feeling that results from physical stimulation
Frequency
Sensation
Perceptual Development
Lateral Inhibition
21. Refers to the entire span that can be perceived or detected by the eye at a given moment.
Muller-Lyer Illusion
Visual Field
Receptor Cells
Constancy
22. Says that the strength of a stimulus must be significantly increased to produce a slight difference in sensation
23. After the optic chasm - information travels to the...
Ewald Hering
binoculary disparity
Receptor Cells
Striate cortex to the visual association areas of the cortex
24. Can be perceived as two different things depending on how you look at them
Ambiguous Figures (illusion)
Symmetry
Constancy
Visual Acuity
25. 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.
James Gibson
Outer ear
Receiver operating characteristic
Constancy
26. 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.
binoculary disparity
The visual pathway
Inner ear
Moon Illusion
27. We see objects because of the light they reflect
There are fewer cones per ganglion cells
Vision
Retina
Cones
28. Comes from the complexity of the sound wave
McCollough Effect
Timbre
Opponent Color or Opponent Process Theory
Size Constancy
29. Is the minimum amount of stimuli that can be detected 50% of the time
Absolute threshold
Dark adaptation

Symmetry
30. Is composed of photons and waves measured by brightness and wavelengths
Reception
Gestat Ideas
Light
Depth perception
31. The optic nerve is made up of...
1000hz
Ganglion cells
Cornea
Inner ear
32. 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
Brightness
False alarm
Autokinetic effect
Phi Phenomenon
33. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.
