Instructions:
Answer 50 questions in 15 minutes.

.
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.

19. Why do cones see better than rods?
Optic Chasm
Symmetry
Reception
There are fewer cones per ganglion cells
20. 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.

Middle ear
Depth perception
Optic Array
21. Is the tendency to make figures out of symmetrical images
Reception

The visual pathway
25. Is the minimum amount of stimuli that can be detected 50% of the time
James Gibson
Absolute threshold
Minimum principle
Color constancy
26. Are particularly sensitive to dim light and are used for night vision. They are also concentrated along the sides of the retina - making them extremely important for peripheral vision
Visual Cliff
Color constancy
Rods
Middle ear
27. 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.
Light
motion parallax
Cones
binoculary disparity
28. Are concentrated in the center of the retina. They are sensitive to color and daylight vision.
