Zajonc (1965) wrote an influential article in which he posited a theoretical explanation for the social facilitation effect. Elegantly simple, this explanation included two steps:

a. the presence of others causes arousal, and arousal makes it easier to do simple things and harder to do difficult or new things. b. the actors are concerned about evaluation, and the most dominant response is activated. c. the presence of others is distracting, and distractions make it more difficult to perform. d. the performance of difficult tasks is arousing, and arousal impedes performance.

Firdous always complains of a tickling sensation in her palms. She has visited several physicians who have assured her that she is physically healthy.

A) depersonalization-derealization disorder. B) illness anxiety disorder. C) posttraumatic stress disorder. D) dissociative identity disorder.
