Preferences for separating or combining events.

This research investigates people's preferences for temporally separating or combining emotionally impactful events. For instance, do people prefer to experience 2 negative events (e.g., manuscript rejections) on the same day or on different days? Do people prefer to experience 2 positive events (e.g., manuscript acceptances) on the same or different days? This article proposes a renewable resources model that combines elements of decision-making models (prospect theory) with the notion that people possess limited but renewable physiological, cognitive, and social resources for dealing with emotionally impactful events. As predicted, Ss preferred to separate 2 positive events (the gain-savoring hypothesis), to separate 2 negative events (the multiple-loss-avoidance hypothesis), and to combine a positive and a negative event (the loss-buffering hypothesis). Ss displayed identical preferences for events from the academic, financial, and social domains.

Perceived distributions of the characteristics of in-group and out-group members: empirical evidence and a computer simulation.

This research studied 2 properties of perceived distributions of the characteristics of social category members: the probability of differentiating (making distinctions) among category members and the perceived variability (variance) of category members. The results of 4 experiments supported the hypothesis that greater familiarity with a social group leads to greater perceived differentiation and variability regarding that group. In-group members formed more differentiated and variable distributions for groups defined by age and more differentiated distributions for groups defined by nationality. For gender (where students were roughly equally familiar with people of both genders), no in-group--out-group differences occurred. Also, students perceived greater differentiation and variability among classmates over the course of a semester. To explain these results, we developed PDIST, a multiple exemplar model that assumes that people form perceived distributions by activating a set of category exemplars and then judging the relative likelihoods of different feature values on the basis of the relative activation strengths of these feature values. The results of a computer simulation experiment indicated that PDIST is sufficient to explain the results of our 4 experiments. According to the perceived distributions formed by PDIST, increasing familiarity leads to greater differentiation and variability, has a concave impact, and has greater impact on differentiation than on variability.

Self-complexity as a cognitive buffer against stress-related illness and depression.

This prospective study tested the self-complexity buffering hypothesis that greater self-complexity moderates the adverse impact of stress on depression and illness. This hypothesis follows from a model that assumes self-knowledge is represented in terms of multiple self-aspects. As defined in this model, greater self-complexity involves representing the self in terms of a greater number of cognitive self-aspects and maintaining greater distinctions among self-aspects. Subjects completed measures of stressful events, self-complexity, depression, and illness in two sessions separated by 2 weeks. A multiple regression analysis used depression and illness at Time 2 as outcomes, stressful life events and self-complexity at Time 1 as predictors, and depression and illness at Time 1 as control variables. The Stress X Self-Complexity interaction provided strong support for the buffering hypothesis. Subjects higher in self-complexity were less prone to depression, perceived stress, physical symptoms, and occurrence of the flu and other illnesses following high levels of stressful events. These results suggest that vulnerability to stress-related depression and illness is due, in part, to differences in cognitive representations of the self.
