.
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. 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

Retina
There are fewer cones per ganglion cells
2. Failing to detect a present stimulus

3. 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

11. The pace of vibrations or sound waves per second for a particular sound - determines pitch. Frequencies are measured in Hertz
Proximity
Frequency
Moon Illusion
Symmetry
12. 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
Receptive Field
Nativist Theory
Ewald Hering
13. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.
Perceptual Development
Middle ear
Cones
Perception
14. Takes place when receptors for a particular sense detect a stimulus.

Neural Pathways
15. Or overlap of objects shows which objects are closer
Minimum principle
Lateral Inhibition
Response Bias
interposition
16. The part of the world that triggers a particular neuron
Lens

Fechner'S Law
Receptive Field
17. How we organize or experience sensations
apparent size
McCollough Effect
Perception
Photopigments
18. 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
Purkinje shift
Ponzo Illusion
Proximity
Phi Phenomenon
19. Asserts that perception and cognition are largely innate
Proximity
Nativist Theory
apparent size
Ciliary Muscles
20. The clear protective coating on the outside of the eye
Ciliary Muscles
Cornea
Frequency
Response Bias
21. Involves both innate/sensory and is partially learned/conceptual
Ciliary Muscles
Fechner'S Law
Current thinking about sensation and perception
Autokinetic effect
22. Begins with the tympanic membrane (eardrum) which is stretch across the auditory canal. Behind this membrane are the Ossicles (3 small bones) - the last of which is the stapes. Sound vibrations bump against the tympanic membrane - causing the ossicl
Perceptual Development
Differential Threshold
Middle ear

23. Factors into why we see what we expect to see
Mental set

Linear perspective
The visual pathway
Neural Pathways
26. Curces are graphical representations of a subject'S sensitivity to a stimulus
Receiver operating characteristic
The visual pathway
Outer ear
Tri-color Theory (component theory)
27. Proposed the tri-color theory - research shows that the opponent-process theory seems to be at work in the Lateral geniculate body - research shows that the tri-color theory seems to be at work in the Retina
