Research shows that people comply more frequently to threats when the credibility of the source is high rather than low and that compliance is directly related to punishment magnitude. To examine the impact of an advisor on a target of threats, male college students (N=74) participated in an experiment that included high or low threatner…

Within the area of attribution theory, an overjustification effect is inferred if, following reward for an intrinsically interesting activity, individuals subsequently show less interest in that activity than comparable individuals who receive no reward. In an attempt to isolate the overjustification effect, 60 college students (30 male, 30…

Compared the reinforcement expectancies of adult alcoholics with beliefs of men and women in alcohol treatment programs, hospitalized medical patients, and college students through the Alcohol Expectancy Questionnaire (AEQ). Results indicated the previously defined AEQ beliefs apply to the alcoholic population and these populations significantly…

Studies on alcohol and aggression have tended to use male subjects and to employ negative shock deliveries as the measure of aggression. This study was conducted to investigate sex differences in alcohol's effect on aggression and to examine the impact of providing both positive and negative response options. Male (N=48) and female (N=48)…

To determine the influence of successful or unsuccessful competitive outcomes and small or large margins of victory/defeat on performance, pairs of female undergraduate students "competed" against each other in a dart tossing contest. False feedback about the outcomes and margin of victory/defeat led subjects to believe they were winning every…

Alcoholism research has independently focused on background characteristics and alcohol-related expectations, e.g., social and physical pleasure, reduced tension, and increased assertiveness, as important variables in identifying high risk individuals. To assess the utility of alcohol reinforcement expectations as predictors of drinking patterns,…

The effects of feedback letters sent to students thanking them for their course ratings were examined in two experiments. In the first study, students who initially rated the course highly were not affected by the feedback letters. However, after being exposed to poor instructional materials (an inadequately prepared study guide), students who…
