.
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. Objects that have been drawn and can be perceived but are geometrically impossible

18. A thick layer of glass above a surface that dropped off sharply. The glass provided solid - level ground doe subjects to move across in spite of the cliff below. Animals and babies were used as subjects and both groups avoided moving into the 'cliff'

23. Found that infants prefer relatively complex and sensational displays
Muller-Lyer Illusion
Response Bias
Nativist Theory
Robert Frantz
24. 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
Tri-color Theory (component theory)
Rods
Current thinking about sensation and perception
Differential Threshold
25. Ambiguous figures - such as the Rubin vase. They can be perceived as two different things depending on which part you see as the figure and which part you see as the background.
Figure-Ground Reversal Patterns (illusion)
