.
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.

Lens
17. Is the tendency to create a whole or detailed figure based on our expectations rather than what is seen

Continuation
18. Why do cones see better than rods?
motion parallax
There are fewer cones per ganglion cells
Constancy
Eleanor Gibson and Richard Walk
19. 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
Size Constancy
Autokinetic effect
Thomas Young and Hermann von Hemholtz
Closure
20. 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.
Receiver operating characteristic
James Gibson
Receptor Cells
motion parallax
21. Curces are graphical representations of a subject'S sensitivity to a stimulus
Receiver operating characteristic
Optic Chasm
Proximity
Reception
22. Is gained by features we are familiar with - such as two seemingly parallel lines that converge with distance
Impossible Objects
Linear perspective
Cornea
Tri-color Theory (component theory)
23. 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.
Opponent Color or Opponent Process Theory
Brightness
Inner ear
Current thinking about sensation and perception
24. 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
binoculary disparity
Neural Pathways
Differential Threshold
Brightness
25. Saying you detect a stimulus that is not there
Reception
False alarm
Photopigments
Hermann Von Hemholtz
26. The feeling that results from physical stimulation

28. Factors into why we see what we expect to see
Perceptual Development

Proximity
29. Is the way that perceived color brightness changes with the level of illumination in the room. With lower levels of illumination - the extremes of the color spectrum (especially red) are seen as less bright
