Jennifer is terrified of insects. She will not walk on grass or go into any areas with trees. If Dr. Joseph Wolpe, the well-known behavioral therapist, were treating this phobia, which technique would he most likely use?

A) systematic desensitization
B) flooding
C) aversion therapy
D) modeling

Systematic desensitization is a technique used in behavioral therapy to help individuals overcome phobias and anxiety by gradually exposing them to the feared stimulus in a controlled and safe manner. In this case, Dr. Joseph Wolpe would use systematic desensitization to gradually expose Jennifer to insects, first in her imagination and then in real-life situations, until she no longer experiences fear or anxiety in their presence. Flooding, aversion therapy, and modeling are other techniques used in behavioral therapy, but they may not be appropriate or effective for treating Jennifer's specific phobia of insects.
