.
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.
1. Is the tendency to see what is easiest or logical to see

2. It travels through the horizontal cells to the bipolar cells to the amacrine cells. Finally the information heads to the ganglion cells.

10. 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.
Dark adaptation
Lateral Inhibition
Ganglion cells
McCollough Effect
11. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.
12. 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
13. Is the minimum amount of stimuli that can be detected 50% of the time
Receptive Field

Absolute threshold
Retina
14. Refers to the entire span that can be perceived or detected by the eye at a given moment.

15. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.

Cones
Reception
David Hubel and Torsten Wiesel
16. 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.
Ganglion cells
Nativist Theory
Differential Threshold
Closure
17. Suggests that there are three types of receptors in the retina: cones that respond to red - blue - or green
Opponent Color or Opponent Process Theory
Impossible Objects
Tri-color Theory (component theory)
Gestalt Psychology
18. 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.
Depth perception
Continuation
Opponent Color or Opponent Process Theory
Neural Pathways
19. 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.
Autokinetic effect
Receiver operating characteristic
Robert Frantz
David Hubel and Torsten Wiesel
20. 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
McCollough Effect
Purkinje shift
Muller-Lyer Illusion
Phi Phenomenon
21. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.
Optic Chasm
Photopigments
Robert Frantz
Gestalt Psychology
22. Refers to how we see texture or fine detail differently from different distances
texture gradient
Cones
Differential Threshold
Outer ear
23. Proposed the perceptual development and optic array
Timbre
James Gibson
Correct Rejection
Fovea
24. How we organize or experience sensations
Gestalt Psychology
David Hubel and Torsten Wiesel
Perception
False alarm
25. Or overlap of objects shows which objects are closer
Visual Acuity
interposition
1000hz
Vision
26. Consists of one optic nerve connection each eye to the brain.
Visual Pathway
Muller-Lyer Illusion
After light passes through receptors
Ewald Hering
27. Is when two horizontal lines of equal length appear unequal because of two vertical lines that slant inward
Gestalt Psychology
Visual Pathway
Dark adaptation
Ponzo Illusion
28. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'
Vision

29. 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
