a desire for significant accomplishment, for mastery of skills or ideas, for control, and for attaining a high standard.

achievement test

a test designed to assess what a person has learned.

in classical conditioning, the initial stage, when one links a neutral stimulus and an unconditioned stimulus so that the neutral stimulus begins triggering the conditioned response. In operant conditioning, the strengthening of a reinforced response.

active listening

empathic listening in which the listener echoes, restates, and clarifies. A feature of Rogers' client-centered therapy.

acute schizophrenia

(also called reactive schizophrenia) a form of schizophrenia that can begin at any age; frequently occurs in response to a traumatic event.
