Ψ  Self Test for Sensation

Note: These questions are part of a larger data base of questions on Module 5 & 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.
