A prospective study tested the hypothesis that college grade point average would be predicted by time-management practices. Ninety college students completed a time-management questionnaire in 1983; their high school Scholastic Aptitude Test (SAT) scores were obtained from college records. Principal-components analysis of the 35-item time-management instrument revealed 3 components. In 1987, 4 years later, each student's cumulative grade point average was obtained from college records. Regression analyses showed that 2 time-management components were significant predictors of cumulative grade point average (R 2 = .21) and accounted for more variance than did SAT scores (increment in R 2 = .05). It is concluded that time-management practices may influence college achievement.

A case is made for the substitutability of self-esteem regulation mechanisms such as cognitive dissonance reduction, self-affirmation, and social comparison. For example, a threat to self via cognitive dissonance might be reduced by a favorable social comparison outcome. To explain substitution, it is suggested that self-esteem regulation mechanisms inevitably produce affect and that affect mediates the completion of various self-esteem regulation processes. Substitution can be understood in terms of the transfer of affect from the initial mechanism to the substitute mechanism. To be effective, this transfer must take place without awareness. Also discussed is the substitution of self-esteem regulation mechanisms across different self-domains versus within a single self-domain. Current theory suggests that substitution might be more effective within domain; that is, it is better to bolster the aspect of self that has been threatened. It is suggested here, however, that substitution across self-domain might be relatively resilient and easier to accomplish.

A self-evaluation maintenance (SEM) model of social behavior was described. According to the comparison process, when another outperforms the self on a task high in relevance to the self, the closer the other the greater the threat to self-evaluation. According to the reflection process, when another outperforms the self on a task low in relevance to the self, the closer the other the greater the promise of augmentation to self-evaluation. Affect was assumed to reflect threats and promises to self-evaluation. In three studies, subjects were given feedback about own performance and the performance of a close (friend) and distant (stranger) other on tasks that were either low in self-relevance (Study 2) or that varied in self-relevance (Studies 1 and 3). In Study 1 (N = 31), subjects' performance on simple and complex tasks after each feedback trial served as a measure of arousal. Being outperformed by a close other resulted in greater arousal than being outperformed by a distant other. In Study 2 (N = 30), evaluative ratings of words unrelated to task performance served as an indirect measure of affect. Results indicated that when relevance is low, more positive affect is associated with a friend's outperforming the self than either a friend's performing at a level equal to the self or being outperformed by a stranger. In Study 3 (N = 31), subjects received feedback while their facial expressions were monitored. Pleasantness of expression was an interactive function of relevance of task, relative performance, and closeness of comparison other. The results of all three studies were interpreted as being generally consistent with the SEM model.
