Ψ  Self Test for Perception

Note: These questions are part of a larger data base of questions on Module 6 & are selected to represent the type of question you should expect on unit exam two. You can, in fact, expect to see many of these very same questions on that exam. Exam questions, however, may deal with topics not covered in the self tests or in lectures but are discussed in your textbook. You are responsible for the content of your text book plus the content of lectures, interactive activities, & material on the web site.

Use these sample questions to test yourself & to practice for the test. Click on your choice to see if you are right.

1. An absolute threshold is the intensity level that you

•  just barely detect.
 •  detect 50 percent of the time.

10. Professor Redd walks into her filled classroom, immediately perceiving students as sitting in rows rather than in a haphazard fashion. This is similar to what principle of perceptual organization?

a closure
b similarity
c simplicity
d figure & ground

11.  Rick is coming in for a night landing in his twin-engine plane. He sees blue lights on the ground before him. Rick perceives this to be the outline of the runway. What principle of perceptual organization is he most likely using?

It's a Mickey Mouse World , isn't it?

12. Given that size constancy appears to be learned, what would a blind person whose sight is suddenly restored say as he looked out the window of an airplane as it flies high above in the sky?

a "Very small people must live in those very small houses down there."
b "It seems that the cars down on the ground are moving very slowly."
c "Why does the color of those houses down there keep changing?"
d "Amazing I can really see those houses very clearly."

a depth, width, height - depth
b depth, convergence, height - depth

15.  If one object partially overlaps another object, the partially overlapping object will appear closer because of the ________ depth cue.

a relative size
b interposition
c retinal disparity
d motion parallax

16. A brochure displays a long stretch of road. The lines that make up the road are drawn so that they converge at the horizon. The result is that the brochure creates a sense of distance. This is based on a monocular cue called

a relative size.
b convergence.
