Stability of Medical Students' Attitudes Toward Aging and Death

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.     

Do Mindsets Shape Students’ Well-Being and Performance?

“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.     

Rethinking Secularism,edited by Craig Calhoun,Mark Juergensmeyer and Jonathan VanAntwerpen,Oxford University Press: Oxford and New York, 2011, vii + 311 pp. ISBN 978 019979667-0, US$99.00 (hbk); ISBN 978 019979668 7, US$24.95 (pbk)

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.

Maintaining proficient supervisor performance with direct support personnel: an analysis of two management approaches

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.     

The impact of contextual information and a secondary task on anticipation performance: An interpretation using cognitive load theory

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.     

A Self‐regulation Perspective on Hidden‐profile Problems: If–Then Planning to Review Information Improves Group Decisions

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

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.     

The effect of social influence on cognitive development and school performance

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.     

毅力人格与数学成绩之间的关系以及学习行为投入的中介作用:以PISA 2012中国上海数据为例

通过分析PISA 2012中国上海中学生样本,探讨毅力人格对数学成绩的影响,尤其是学习行为投入的中介作用。结果显示,毅力人格包含了代表缺乏毅力、容易放弃的负性维度,以及代表富有毅力、追求完美的正性维度。负性维度能负向预测数学成绩,学习行为投入起部分中介作用。正性维度对数学成绩的总效应和直接效应不显著,只通过学习行为投入产生正向间接影响。负性维度对数学成绩的负面影响整体强于正性维度的正面作用。因此教学中对数学成绩不佳的学生,应根据其毅力水平给予不同引导。
