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.

10. Also known as just noticeable difference. The minimum difference that must occur between two stimuli - in order for them to be perceived as having different intensities.

Optic Array
15. Asserts that perception and cognition are largely innate
Figure-Ground Reversal Patterns (illusion)

Nativist Theory
16. 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.

Figure-Ground Reversal Patterns (illusion)
Receptor Cells
17. Curces are graphical representations of a subject'S sensitivity to a stimulus
Sensation
Reception
Receiver operating characteristic
Muller-Lyer Illusion
18. How movement is perceived though the displacement of objects over time - and how this motion takes place at seemingly different paces for nearby or faraway objects. Ships far away seem to move more slowly than ships moving at the same speed.
Proximity
Vision
motion parallax
Dark adaptation
19. 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.
Depth perception
Continuation
Optic Chasm
Constancy
20. 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.
Lateral Inhibition
Autokinetic effect
Receptive Field
Moon Illusion
21. Refers to the entire span that can be perceived or detected by the eye at a given moment.
Visual Field
Robert Frantz
Cones
Current thinking about sensation and perception
22. Individuals are partly motivated by rewards and costs in detection. The interplay between response bias and stimulus intensity determines responses
Response Bias
Visual Pathway
Mental set
Phi Phenomenon
23. The center of the retina; has the greatest visual acuity
Fovea
Retina
There are fewer cones per ganglion cells
Sensation
24. Located in the back of the eye - receives light images from the lens. It is composed of about 30 million photoreceptor cells and of other cell layers that process information
Size Constancy
Perception
Visual Pathway
Retina
25. Rods and cones on the retina that are responsible for sensory transduction.
Lens
Timbre
Receptor Cells
James Gibson
26. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen
Middle ear
Opponent Color or Opponent Process Theory
Receptor Cells
Continuation
27. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear
Constancy
Optic Array
Terminal Threshold
Phi Phenomenon
28. 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.
Rods
Robert Frantz
Differential Threshold
Opponent Color or Opponent Process Theory
29. Defined the Just Noticeable Difference
Receptive Field
Robert Frantz
Symmetry
E.H. Weber
30. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.
Optic Chasm
Dark adaptation
Perceptual Development
Figure and ground relationship
31. Allow the cornea to bend (accommodate) in order to focus an image of the outside world onto the retina
Minimum principle
Ciliary Muscles
Continuation
Structuralist Theory
32. The most famous of all visual illusions. Two horizontal lines of equal length appear unequal because of the orientation of the arrow marks at the end. Inward facing arrow marks make the line appear shorter than another line of the same length with ou
Middle ear
Gestat Ideas
Muller-Lyer Illusion
Amplitude
33. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz
Opponent Color or Opponent Process Theory
Receptive Field
Lateral Inhibition
Frequency
34. 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
Continuation

Linear perspective
35. Electrical impulses travel down these to the brain - where the information is understood
Visual Field
Fechner'S Law
1000hz
Neural Pathways
36. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.
