Rethinking student participation in the college classroom: Can commitment and self-affirmation enhance oral participation?

The literature suggests that in-class oral participation is associated with various positive outcomes that directly contribute to academic success. The goal of the current study was to investigate the role played by psychological barriers to oral participation, focusing on commitment and self-affirmation as methods to bypass barriers to participation. The results of the semester-long experiment (N = 157) demonstrate that committed individuals who had an opportunity to self-affirm outperformed both committed students and affirmed students, as well as members of the control group. Interestingly, the interplay between self-affirmation and commitment increased oral participation, irrespective of whether students had high or low self-esteem and high or low self-efficacy. The current results offer some room for cautious optimism, as they highlight the importance of self-affirmation and commitment as a route to academic success.     

Different roles of shared and vertical leadership in promoting team creativity: Cultivating and synthesizing team members’ individual creativity

Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed.     

Behavioral and pharmacological treatments for tourette syndrome: A review

This article reviews the published treatment outcome research on pharmacological and behavioral treatments for Gilles de la Tourette syndrome (TS). Controlled group outcome studies of pharmacological treatments show about a 50–60% reduction in tics with haloperidol and pimozide and about a 20% reduction with clonidine. A controlled group outcome study and several within-subject design studies of behavioral treatments show about a 90% reduction in tics with habit reversal training. A large number of case studies generally confirm these results and also show benefits from other behavioral treatments such as relaxation training, self-monitoring, and contingency management. Clinical limitations of TS drugs are that they produce side effects in 50–85% of the patients and require continuous use, and long-term compliance with the medications is limited. The primary limitation of behavioral treatments is that they require a large initial time commitment. The methodological strengths of the controlled drug studies are the use of double-blind and group designs. For the behavioral studies, the strengths are rigorous recording and controlled within-subject designs.     

UNDERSTANDING THE STRUCTURE OF STEREOTYPES OF WOMEN: VIRTUE AND AGENCY AS DIMENSIONS DISTINGUISHING FEMALE SUBGROUPS

A two-part study investigated the dimensional structure of stereotypes of women. In one sample ( n = 258), participants sorted traits according to the likelihood that they would co-occur in the same woman. In a separate sample ( n = 102), participants were given the same traits and were asked to judge the traits' desirability and to judge the moral virtue, sexual liberalism/conservatism, warmth, competence, and power of a woman who possessed high levels of each trait. Results from hierarchical cluster analysis indicated that participants perceived women in terms of six subgroups: professional, feminist, homemaker, female athlete, beauty, and temptress. Large differences among these subgroups were identified based on ratings of their moral virtue and sexual conservatism (i.e., virtue) and competence and power (i.e., agency). The implications of a virtue–agency model of female subgroups for gender stereotyping research are discussed.     

Age, marital satisfaction, and optimism as predictors of positive sentiment override in middle-aged and older married couples

This study examined whether positive sentiment override (greater positive appraisal of spouse's affiliative behavior than is warranted by observed behavior) occurred more frequently in older compared with middle-aged married couples and whether age differences were mediated by older adults' greater marital satisfaction when controlling for optimism. Participants included 270 middle-aged (40-50 years old) and older (60-70 years old) couples who discussed a marital disagreement and completed an errand task. Couples provided appraisals of their spouse's affiliation, and the authors coded affiliative interactions using the structural analysis of social behavior. Hierarchical multivariate linear modeling indicated that older husbands and wives viewed their spouse's behavior as more positive during disagreement interactions than did independent observers; in the errand task, only older wives demonstrated positive sentiment override. Age differences in positive sentiment override were mediated by marital satisfaction, even when controlling for optimism. The results are consistent with theories of emotion regulation, such as socioemotional selectivity theory, that suggest that older adults are biased toward the positive aspects of close relationships.     

An analysis of reinforcement sensitivity theory and the five-factor model

Reinforcement Sensitivity Theory (RST) and the Five-Factor Model (FFM) are two prominent personality accounts that have emerged from different backgrounds. Although the two accounts are applied to similar research topics, there is limited empirical work examining the correspondence between them. The current study explored the relationship between RST-based personality traits and the FFM domains and facets in an undergraduate sample (n = 668). Regression analyses indicated that Sensitivity to Punishment (SP) was positively associated with Neuroticism and Agreeableness, and negatively associated with Extraversion, Openness, and Conscientiousness. In contrast, Sensitivity to Reward (SR) was positively associated with Extraversion and Neuroticism, and negatively associated with Agreeableness and Conscientiousness. Exploratory analyses at the facet level specified the relationship between SP, SR, and each domain. A factor analysis was also conducted to explore the higher-order factor structure of RST and the FFM domains. Three factors emerged, which we labelled SP, Stability-Impulsivity, and Sensation Seeking. Taken together, these findings suggest that there is substantial overlap between these two accounts of personality. Copyright © 2007 John Wiley & Sons, Ltd.
