Ψ  Practice Test for
The Biological Perspective



Note: These questions are part of a larger data base of questions & are selected to represent the type of question you should expect on unit exams .  Exam questions, however, may deal with topics not covered in the practice 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.

Neurosis is the inability to tolerate ambiguity.  -- Freud

It will not last the night;
But ah, my foes, and oh, my friends--
It gives a lovely light!
