.
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.

3. 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

10. 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.

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
Autokinetic effect
Perceptual Development
Optic Array
After light passes through receptors
20. Consists of the parts you see called the pinna and the auditory canal. Vibrations from sound move down this canal to the middle ear.

Cones
27. Is the minimum amount of stimuli that can be detected 50% of the time
Absolute threshold
3 steps involving sensation

Ewald Hering
28. 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
