女大学生同性竞争与社交网站发布美化自拍行为的关系：外貌比较的调节作用

为探究女大学生同性竞争与社交网站发布美化自拍行为之间的关系及外貌比较在其中的调节作用,采用同性竞争量表、身体外貌比较问卷和美化自拍量表对463名女大学生进行问卷调查。结果发现：在控制年龄后,女大学生同性竞争可以显著正向预测社交网站美化自拍行为,且这一预测作用受到外貌比较的调节,即只有低外貌比较的女大学生其同性竞争水平可显著预测其美化自拍行为。该结果对理解和干预女大学生的社交网站行为具有一定理论意义和实践意义。     

2003年诺贝尔医学奖给科学界的多重启示(上)

2003年诺贝尔医学奖授予了两位美英物理学家,劳特布尔和曼斯菲尔德,表彰他们在磁共振成像方面的发现.这些发现导致现代磁共振技术的开发,这一技术标志着医学诊断学和科学研究中的一项突破.该项发现建筑在核磁和核磁共振现象被发现的基础之上.核磁现象的发现及其应用导致了1943、1944和1952年诺贝尔物理学奖的获得.核磁共振现象的发现及其应用导致了1991年和2002年诺贝尔化学奖的获得.这意味着,2003年诺贝尔医学奖是该系列发现中第六个诺贝尔科学奖.     

Problem Finding,Creativity Style and the Musical Compositions of High School Students

This study sought to understand the effect of problem finding and creativity style on the creative musical product. Participants (N = 32) were categorized by creativity style (adaptor or innovator) using the Kirton Adaption-Innovation Inventory. The participants completed two musical composition problems involving two different degrees of problem finding behaviors: an open (ill defined) and a closed (more defined) problem. The resulting products were scored for creativity by three judges using a modified version of Amabile's “consensual assessment technique.” A repeated measures analysis of variance (ANOVA) was used to analyze the data. The independent variables were composition problem type and creativity style, and the dependent variable was the creativity score on the open and closed problems. No significant differences due to problem type, creativity style, or the interaction of the two factors was found. This research supports the assertion of Kirton that adaption-innovation theory is a measure of creativity style rather than creativity level, but calls into question its use in individual creativity style.

Facing a breakup: Electromyographic responses moderate self‐concept recovery following a romantic separation

Romantic breakups arouse fundamental questions about the self: Who am I without my partner? This study examined self‐concept reorganization and psychological well‐being over an 8‐week period in the months following a breakup. Multilevel analyses revealed that poorer self‐concept recovery preceded poorer well‐being and was associated with love for an ex‐partner, suggesting that failure to redefine the self contributes to post‐breakup distress. Psychophysiological data revealed that greater activity in the corrugator supercilia facial muscle while thinking about an ex‐partner predicted poorer self‐concept recovery and strengthened the negative association between love for an ex‐partner and self‐concept recovery. Thus, the interaction between self‐report and psychophysiological data provided information about the importance of self‐concept recovery to post‐breakup adjustment not tapped by either method alone.     

Learning Emotional Intelligence: An Exploratory Study in the Domain of Health

This research examines the role of emotional intelligence (EI) on the adoption and maintenance of a healthy weight. We implemented an intervention over a 6‐week period demonstrating that EI can be learned to promote the use of cognitive health knowledge in the adoption and maintenance of a healthy weight. Results suggest that improving EI reduces the negative impact of low EI on positive health outcomes, and promotes quality decision making related to health (i.e., reduced calorie intake).     

A TRICKLE‐DOWN MODEL OF ABUSIVE SUPERVISION

Much of the abusive supervision research has focused on the supervisor–subordinate dyad when examining the effects of abusive supervision on employee outcomes. Using data from a large multisource field study, we extend this research by testing a trickle‐down model of abusive supervision across 3 hierarchical levels (i.e., managers, supervisors, and employees). Drawing on social learning theory and social information processing theory, we find general support for the study hypotheses. Specifically, we find that abusive manager behavior is positively related to abusive supervisor behavior, which in turn is positively related to work group interpersonal deviance. In addition, hostile climate moderates the relationship between abusive supervisor behavior and work group interpersonal deviance such that the relationship is stronger when hostile climate is high. The results provide support for our trickle‐down model in that abusive manager behavior was not only related to abusive supervisor behavior but was also associated with employees’ behavior 2 hierarchical levels below the manager.     

INTELLECTUAL VIRTUE AND THE JUSTIFICATION OF PERSONS

In this paper, I develop a model of personal justification that is rooted in the intellectual virtues and the concept of epistemic praise. In particular, I show how a character‐based understanding of the virtues gives rise to an important emphasis on agents and how this provides the resources for dealing with several problems in epistemology.     

The consequences of high levels of attachment security

Attachment security is known to have various positive outcomes. Recent evidence, however, suggests that security, especially high levels of it, may also have negative outcomes. Three studies tested this possibility. Studies 1 and 2 showed a linear rather than curvilinear trend between security and positive outcomes, suggesting that even at high levels security correlates with positive outcomes. Study 3, which focused on secure behaviors, found that exhibiting high levels of secure behaviors was related to a higher frequency of negative outcomes. However, dispositional attachment security was negatively correlated with negative outcomes, and engaging in secure behaviors strengthened this correlation. These findings suggest that secure behaviors rather than perceptions associated with attachment security (i.e., working models) may be related with negative outcomes.
