I have got to write an essay in a "Psychological Critical Perspective" viewpoint, comparing two different plays "Odeipus Rex" and "Trifles". I will be comparing two different plays, characters, and settings. My problem is I do not understand how to go about doing this. Can you help me to understand.

What is "Psychological Critical Perspective"?

Psychological critical perspectives is a development of the issues that motivated the lead characters behavior, not much different that what happens under psychoanalysis. If you can focus on the determining issues, you can change behavior...so the belief goes.
