The clinical psychologist assessed person B's personality using a test based on less structured stimuli. The test helped to assess his unconscious motives and feelings. Identify the test used by the psychologist.

Projective Technique

The correct answer is Projective Technique.

Projective techniques are a type of psychological test that uses ambiguous stimuli to assess a person's unconscious motives, feelings, and personality traits. These tests are based on the assumption that when people are presented with ambiguous stimuli, they will project their own internal thoughts and feelings onto the stimuli.

Self-report measures, behavioral analysis, and psychometric tests are all structured tests that rely on direct responses or observations of behavior. They do not use ambiguous stimuli or attempt to assess unconscious motives or feelings.
