.
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. Where half of all fibers from the optic nerve of each eye cross over and join the optic nerve from the other eye. This insures input from each eye will be put together in a full picture in the brain.

7. 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.

8. Suggests that subjects detect stimuli not only because they can but also because they want to. TSD factors motivation into the picture.

Rods
3 steps involving sensation
1000hz
Figure-Ground Reversal Patterns (illusion)
16. 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

22. Revolves around perception and asserts that people tend to see the world as comprised of organized wholes. The world is understood through top-down processing.
Gestalt Psychology
Current thinking about sensation and perception
Visual Pathway
Hermann Von Hemholtz
23. Takes place when receptors for a particular sense detect a stimulus.

Robert Frantz
26. Failing to detect a present stimulus

There are fewer cones per ganglion cells
27. 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
