Is there an age deficit in the selection of mental sets?

Efficient selection of actions is dependent on higher-level constraints (mental sets) on lower-level selection. This paper explores the hypothesis that ageing leads to specific impairments associated with higher-level selection between mental sets. Indirect evidence for such a deficit comes from occasional findings of age differences in situations with high executive-control demands (e.g., Mayr & Kliegl, 1993) that are not easily explained in terms of other factors, such as general slowing or working memory parameters. More direct evidence comes from recent results with the so-called task-switching paradigm. Specifically, age-sensitive set-selection processes are indicated by age differences in “global selection costs” (i.e., the response-time difference between task-switching blocks and single-task blocks) which seem to be particularly large when demands in terms of “keeping competing mental sets apart” are high. Finally, data from a new variant of the task-switching paradigm (the “fade-out paradigm”) are reported which show that age differences in global costs persist substantially beyond a phase in which set-selection is actually necessary. Generally, evidence is consistent with the view that in older age, a costly set-selection mode of processing dominates over the more efficient within-set-selection mode of processing, possibly because of a problem with maintaining distinct representations of what ought to be done in the face of competing representations of what could be done in principle.     

Self-Presentation Concerns and Health Behaviors Among Cosmetic Surgery Patients

The present investigation examined the relationship between self-presentational motives and physical activity in a population of cosmetic surgery participants. Participants were 50 female and 5 male cosmetic surgery patients (CSPs; M age = 38.5 years) who completed a battery of self-report measures following either vein or acne treatment. Analyses revealed significant group differences on self-presentational concern and public self-consciousness between: (a) those who elected the treatment for appearance motives and those who elected treatment for health-based motives, and (b) the more frequent (3 or more times per week) and less frequent (2 or less times per week) exercisers. Greater self-presentational concerns and greater public self-consciousness were associated with having appearance-related motives for treatment and with being a less frequent exerciser.     

Rodney King and O. J. Revisited: The Impact of Race and Defendant Empathy Induction on Judicial Decisions

White university students participated in a study to investigate the impact of defendant race and empathetic induction on a subsequent juror decision-making task. Participants read a passage involving a Black or a White defendant in a criminal case. They were subsequently induced to feel no empathy, low empathy, or high empathy for the defendant. When compared to participants in the low- and control empathy conditions, those in the high-empathy condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. The results also indicate that group membership can moderate the impact of empathetic induction. When compared to the participants in the Black defendant condition, those in the White defendant condition reported greater target empathy, made attributions that were more situational, and assigned more lenient punishments. Implications for both empathy and judicial decision-making research are discussed.     

The Personal Is the Political: Antecedents of Gendered Choices of Elected Representatives

This article focuses on the legislative careers of women and men in state legislative office to explore how the relationship between the private and public spheres affects career opportunities, choices, perceptions, and actions. The findings indicate that the intersection of private and public is configured differently in the lives of women and men. Among other results, women were found to perform double duty, holding primary responsibility for the work of home and children even though they have the same public responsibilities as their male counterparts. The implications of these findings for individuals, public policy choices, institutional operations, and social patterns are explored.     

Gender Differences in the Construct Validity of the Silencing the Self Scale

Gender differences in the construct validity of Jack's (1991) Silencing the Self Scale (STSS) were assessed using 187 female and 169 male undergraduates. Results of exploratory and confirmatory factor analyses revealed gender differences in the scale's latent structure and at best provided only limited support for the validity of the scale's four subscales for women. Among men, the studies exposed a weakness in the scale's construct validity and provided insights into possible alternative interpretations made by men when responding to the scale's items. Convergent and discriminant validity of the scale were assessed by correlating it with measures of neuroticism and attachment. Whereas the construct validity of the STSS for use with women was supported, evidence was weaker for men. For men, data suggest that the STSS, in part, taps a motive to avoid intimacy and relationship situations that limit one's sense of independence and autonomy, a construct incongruous with Jack's notion of self-silencing.
