Forty Ss from introductory psychology classes participated in a study to determine whether or not the investigator's group Social Expectations Scale (SES) was a useful research instrument and to determine whether or not intelligence was a factor determining the fit of a particular cognitive model, the BSE, to the social expectations of Ss as measured by the SES.

This investigation was designed to determine relative effects of monetary reward and knowledge of results on complex-choice reaction time tasks. Subjects were twenty-five male and thirty-two female undergraduate students. Apparatus consisted of nine stimulus lights and eight response keys. Subjects were required to add the number of lights presented, subtract the sum from a constant, and press the correctly numbered response key. Reward subjects received twenty-five cents for responses faster than a predetermined criterion, and twenty-five cents was deducted for slower responses. Knowledge of results subjects were told their reaction times after each trial. Results indicated (1) no significant differences between any conditions, (2) a significant overall practice effect (.01 level), and (3) that males were significantly faster than females (.01 level).
