Patricia believes that the purpose of jealousy in men is to prevent their mates from becoming impregnated by other men. The reason why it is so common, she argues, is that this is a very adaptive behavior from an evolutionary perspective

Patricia's approach to jealousy is an example of
A) structuralism.
B) functionalism.
C) empiricism.
D) behaviorism.

Answer: B
Rationale: Functionalism is the study of the purpose and function of behavior and conscious experience. In this example, Patricia is arguing that the "function" of male jealousy is to avoid raising the offspring of another male. William James, who developed functionalism, was greatly influenced by Darwin's theory of evolution.
