The purpose of this study was to examine the relationships between leadership and military teams' affective and cognitive processes and the subsequent links between these processes and team effectiveness. Soldiers (N = 148) from 32 teams completed questionnaires assessing these variables. Hierarchical linear modeling was used to analyze the data. Transformational leadership was positively associated with cognitive and affective processes, but only active management-by-exception leadership was related to negative affect. Neither form of management-by-exception leadership related to cognitive processes. Positive affect, negative affect, and cognitive processes were all related to team viability. Finally, some mediation effects were observed. Implications of the results for developing leadership in military teams are drawn. 相似文献

Two hundred and one unemployed men and women participated in a cross‐sectional study that assessed self‐esteem, financial deprivation, number of alternate roles, and use of social support. Financial deprivation, alternate roles, and social support each had a main effect on self‐esteem. In addition, these variables interacted with gender to affect self‐esteem. Specifically, financial deprivation had a greater negative association with self‐esteem in men as compared with women. In contrast, alternate roles and social support had a stronger positive relationship to self‐esteem in women than in men. The incorporation of these findings into intervention programs for unemployed persons is discussed. 相似文献

Emotional information is often remembered better than neutral information, but the emotional benefit for positive information is less consistently observed than the benefit for negative information. The current study examined whether positive emotional pictures are recognised better than neutral pictures, and further examined whether participants can predict how emotion affects picture recognition. In two experiments, participants studied a mixed list of positive and neutral pictures, and made immediate judgements of learning (JOLs). JOLs for positive pictures were consistently higher than for neutral pictures. However, recognition performance displayed an inconsistent pattern. In Experiment 1, neutral pictures were more discriminable than positive pictures, but Experiment 2 found no difference in recognition based on emotional content. Despite participants’ beliefs, positive emotional content does not appear to consistently benefit picture memory. 相似文献

A Multivariate Analysis of the Revised Conners' Teacher Rating Scale with Low-Income, Urban Preschool Children 总被引:2,自引:0,他引:2

The present investigation addressed the utility of the revised Conners' Teachers Rating Scale (CTRS-28) with low-income urban preschool children. CTRS-28 ratings for a large sample of preschool children from an urban Head Start program were analyzed using exploratory factor analysis. Analyses yielded a 3-factor structure: Conduct problems, Hyperactivity, and Passivity. Further analyses cross-validated this structure for males and females and supported its integrity. Multimethod, multisource validity analyses substantiated the CTRS-28 dimensions. The Play Disruption factor of the parent and teacher Penn Interactive Peer Play Scales (PIPPS) provided convergent validity for the Conduct and Hyperactivity factors of the CTRS-28, whereas the Play Interaction factor revealed divergent validity. The Play Disconnection factor of the PIPPS validated the CTRS-28 Passivity factor. The Q-Sort Emotional Regulation scale provided divergent validity for the Conduct and Hyperactivity factors and likewise the Q-Sort Autonomy scale provided divergent validity for the Passivity factor. Age and sex differences were assessed across the 3 factors of the derived preschool structure. A main effect was found for sex and age indicating that boys displayed higher levels of Hyperactivity and Passivity problems than girls did. Similarly, 4-year-old children demonstrated higher levels of Passivity problems than did 5-year-old children. 相似文献

Daily affective reactivity refers to the within-subject relationship between daily stress and daily mood. Most stress researchers have conceptualized daily affective reactivity as a dependent variable to be predicted by individual difference variables such as personality and psychopathology. In contrast, in our recent research, we have conceptualized daily affective reactivity as an independent variable that can predict depressive symptoms. In this article, we summarize three studies that relied on a daily process methodology and multilevel modeling to assess affective reactivity in the context of daily stressful events. Two of the studies (Cohen, Butler, Gunthert, & Beck, 2005; Gunthert, Cohen, Butler, & Beck, 2005) sampled adult outpatients in cognitive therapy and evaluated the predictive role of daily affective reactivity in treatment outcome (depression reduction). A third study (O'Neill, Cohen, Tolpin, & Gunthert, 2004) evaluated the predictive role of college students' daily affective reactivity in the development of depressive symptoms. We consider the strengths and weaknesses of a daily process methodology for research on depression in both clinical and nonclinical samples. 相似文献

This study examined sex differences in body image change and its correlates over the course of a 12-week strength-training program. Participants were 28 men and 16 women (M age = 21.6, SD = 2.4) who completed pre- and post-intervention measures of body image (Body Areas Satisfaction Scale, Social Physique Anxiety Scale, and Drive for Muscularity Scale) and subjective and objective assessments of body fat, muscularity, and strength. They participated in a 12-week, 5-day/week full-body progressive resistance training program. Significant body image improvements were found for both sexes (p < .05). Correlates of body image change varied somewhat between the sexes. For men, body image improvements were correlated only with subjective physical changes. For women, body image improvements were correlated with subjective physical changes as well as objective increases in strength. These results suggest that although men and women derive body image improvements from strength training, they may benefit for different reasons. 相似文献

This research examined a revised version of the Merrill-Palmer Scale, a test of childhood development, to assess the cultural validity of items, i.e., Differential Item Functioning. Archival data were used to determine the Differential Item Functioning of items for 245 African-American, Euro-American, and Hispanic children, ages 3-6 years. Subjects were gathered from all four regions of the United States. Potential bias was examined through the use of partial correlations. Statistical analyses suggest that the Tryout Edition of the Merrill-Palmer Scale-Revised was not systematically biased toward any of the three racial groups examined. 相似文献
