A representative sample from a nonclinical population was drawn to compare bingers and nonbingers across weight categories. Subjects were 112 women drawn from a cross-section of undergraduate classes at a large state university. Four groups were formed: obese bingers, obese nonbingers, normal-weight bingers (bulimics), and normal-weight nonbingers. Bingers, regardless of weight category, suffered higher levels of depression and anxiety and lower levels of self-esteem than nonbingers, regardless of weight category. Obese nonbingers were indistinguishable on these variables from normal-weight nonbingers, with both groups of nonbingers experiencing less emotional distress. Results support the position that the obese population should be conceptualized and treated as a diverse group with different psychological characteristics and needs. 相似文献

“Mindsets (or implicit theories) are people’s lay beliefs about the nature of human attributes, such as intelligence or personality”. Individuals with a fixed mindset believe that intelligence is an unchangeable trait, whereas those with a growth mindset think of it as a malleable quality that can be increased and developed. This study explored the relationships among growth mindset, wellbeing, and performance in a sample of 1,240 students from a multi-campus private university located in 18 states across Mexico. Our results indicated that individuals who scored high in growth (vs. fixed) mindset showed increased levels of wellbeing and also performed better in school. Furthermore, we found that wellbeing mediated the relationship between growth mindset and performance and that the effect of growth mindset on grades was higher among younger students. These findings have interesting implications for psychology and education. 相似文献

Neo-monasticism, including the desire to live in Christian intentional community, is increasingly popular in the United States. Communities are structured around a rule or shared covenant that outlines the parameters of living in community. Daily prayer is often a central feature to neo-monastic life as is an emphasis on socio-ecological justice. Drawing on recent Christian theology about gardens, a popular neo-monastic book of common prayer, interviews with practitioners of neo-monasticism, and fieldwork conducted with a nascent neo-monastic community in the southeastern United States, this article argues that prayer acts as a religious technology of the self for socio-ecological change. Through prayer, participants of intentional communities change, and this in turn leads to acts that alter the socio-ecological worlds around them. 相似文献

A traditional management approach using indirect feedback was compared to an approach involving direct feedback for maintaining supervisory proficiency in observing and providing feedback to staff. Three supervisors participated in each condition. The first 3 supervisors then received direct feedback. Direct feedback was accompanied by high levels of performance relative to the indirect feedback protocol. The need for maintenance procedures with supervisors is discussed. 相似文献

The impact of contextual information and a secondary task on anticipation performance: An interpretation using cognitive load theory 下载免费PDF全文

When performing under severe time constraints, sports performers use kinematic and contextual information to facilitate anticipation. We examined the relative importance of these two information sources and their impact on cognitive load and anticipation performance. Cognitive load theory predicts that adding more information sources to a task will increase cognitive load in less‐skilled but not skilled performers. Skilled and less‐skilled cricket batters anticipated deliveries from bowlers on a life‐size screen under 4 conditions that manipulated access to contextual information and included a secondary task. The presence of context enhanced anticipation accuracy for both skilled and less‐skilled groups, without affecting cognitive load. Skilled performers used sequencing and game‐related contextual information in addition to kinematic information to facilitate anticipation, whereas both groups reported using information pertaining to opponent positioning. Findings highlight the importance of context in anticipation and suggest that the addition of context may not necessarily negatively impact cognitive load. 相似文献

A Self‐regulation Perspective on Hidden‐profile Problems: If–Then Planning to Review Information Improves Group Decisions 下载免费PDF全文
In hidden‐profile (HP) problems, groups squander their potential to make superior decisions because members fail to capitalize on each other's unique knowledge (unshared information). A new self‐regulation perspective suggests that hindrances in goal striving (e.g., failing to seize action opportunities) contribute to this problem. Implementation intentions (if–then plans) are known to help deal with hindrances in goal striving; therefore, supporting decision goals with if–then plans should improve the impact of unshared information on group decisions. Indeed, in line with past research, control participants in two experiments rarely identified the best alternative despite monetary incentives and setting decision goals. In contrast, simply adding if–then plans to review advantages of the non‐preferred alternatives before making the final decision significantly increased solution rates. Process manipulations (Experiment 1) and measures (Experiment 2) indicate that conceptualizing HP problems as a self‐regulation challenge provides explanatory power beyond existing accounts.

Collective‐efficacy as a mediator of the relationship of leaders' personality traits and team performance: A cross‐level analysis 下载免费PDF全文
Xiaoshan Li Mingjie Zhou Na Zhao Shanshan Zhang Jianxin Zhang 《International journal of psychology》2015,50(3):223-231
The relationship between a leader's personality and his team's performance has been established in organisational research, but the underlying process and mechanism responsible for this effect have not been fully explored. Both the traditional multiple linear regression and the multilevel structural equation model approaches were used in this study to test a proposed mediating model of subordinates' perception of collective efficacy between leader personality and team performance. The results show that the team leader's extraversion and conscientiousness personality traits were related positively to both the team‐average (individual) perception of collective efficacy and team performance, and the collective efficacy mediated the relationship of the leader's personality traits and team performance. This study also discusses how Chinese cultural elements play a role in such a mediating model. 相似文献

Three months before school entrance a sample of 29 children and their mothers was tested for degree of decentred child educability and degree of decentred maternal teaching. Mother and child were tested in two different situations, thus preventing interdependency between the measures of mother and child. Four months after school entrance, teacher judgements of school performance were obtained. A strong correspondence between degree of decentred child educability and degree of decentred maternal teaching was demonstrated. Degree of decentred maternal teaching and degree of decentred child educability were found to be good predictors of school performance, accounting for respectively 45 and 33% of the variance in school performance. In contrast a test of school readiness only accounted for 2% of the variance. A test of intelligence given after the teacher judgement accounted for 31% of the variance. The fact that the mother seems to be a better predictor of her child's school performance than the child himself, supports the assumption that parents, particularly mothers, are important mediators between the child and the outer world. 相似文献

本文建立基于IPO模型的团队多样性-冲突-绩效的权变模型。通过对国内外的112篇实证文章(n=9263)进行元分析,本文定量地梳理近年来团队多样性-团队冲突-团队绩效之间关系的研究文献,并重点考察团队冲突与团队绩效之间的调节变量。元分析结果发现:团队深层多样性是引起团队冲突的重要因素,表层多样性并不会显著增加团队冲突;与美国的研究不同,中国情境下任务冲突将显著降低团队绩效;被试类型、回收率、团队规模和团队冲突的不对称感知等变量调节团队冲突与团队绩效之间的关系。 相似文献
