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.

16. Asserts that perception is the sum total of sensory input. The world is understood through bottom-up processing
Constancy
Rods
Color constancy
Structuralist Theory
17. 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.
Current thinking about sensation and perception
Opponent Color or Opponent Process Theory
Impossible Objects
Neural Pathways
18. After images are perceived because of fatigued receptors. Because our eyes have a partially oppositional system for seeing colors - such as red-green or black-white - once on side is overstimulated and fatigued - it can no longer respond and is overs
Figure-Ground Reversal Patterns (illusion)
Closure
Dark adaptation
McCollough Effect
19. 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.
motion parallax
Ewald Hering
Differential Threshold
Color constancy
20. Has been explained as the increasing ability of a child to make finer discriminations among stimuli.
Perceptual Development
Fovea
Photopigments
Neural Pathways
21. The physical intensity of a sound wave largely determines loudness
1000hz
binoculary disparity
Amplitude
Continuation
22. Is the upper limit above which the stimuli can no longer be perceived. -The highest pitch sound a human could hear
Amplitude
Differential Threshold
Terminal Threshold
Optic Array
23. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.
24. Electrical impulses travel down these to the brain - where the information is understood
Figure-Ground Reversal Patterns (illusion)
Neural Pathways
Thomas Young and Hermann von Hemholtz
Moon Illusion
25. Is the tendency to make figures out of symmetrical images
Neural Pathways
Differential Threshold
Symmetry

Linear perspective
Prosopagnosia
Constancy
29. Or overlap of objects shows which objects are closer

30. 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
