Sensation & Perception Study Guide
Sensation and Perception - Final Exam/Review Sheet
1. Identify by name the theory that investigates perception by presenting a stimulus signal in the presence of noise. What can we learn from the four possible categories of responses?
2. People are often described as being “nearsighted” or “farsighted.” To what actual conditions do these lay terms refer, and what why is it a problem?
3. Identify the visual defect that occurs when the course of the lightwaves entering your visual system are altered by an unequal curving of the surfaces of the eye (usually the cornea), and how to correct this defect.
4. What term is used to describe the ability to accurately “read” fine detail? In which two sensory systems is the term applied, and what is the adjective that precedes the term in each case?
5. What is it called when one eye responds more quickly to a presented stimulus than does the other eye?
6. What is the function of the 1-mm block of striate cortex containing “all the machinery necessary to look after everything the visual cortex is responsible for, in a certain small part of the visual world,” and how does it accomplish that?
7. Identify the area of the brain responsible for processing visual information, and from where it receives its inputs.
8. What is it called when one has a misalignment of the two eyes, so that a single object in space is imaged on the fovea of one eye, and on a nonfoveal area of the other (turned) eye? What should be done about this problem?
9. Explain how one may obtain an additive color mixture, and how it differs from a subtractive color mixture.
10. Explain how one may obtain a subtractive color mixture, and how it differs from an additive color mixture
11. Of the 3 dimensions of color space, which has to do with the strength of a color? Give an example to further explain the concept.
12. Of the 3 dimensions of color space, which has to do with the actual “color” of a color? Give an example
