The effects of autonomy and empowerment on employee turnover: test of a multilevel model in teams

Extending research on voluntary turnover in the team setting, this study adopts a multilevel self-determination theoretical approach to examine the unique roles of individual and social-contextual motivational precursors, autonomy orientation and autonomy support, in reducing team member voluntary turnover. Analysis of multilevel time-lagged data collected from 817 employees on 115 teams indicates that psychological empowerment mediates the main effect of autonomy orientation and the interactive effect of autonomy support and its differentiation on a team member's voluntary turnover. The findings have meaningful implications for the turnover and self-determination literatures as well as for managers who endeavor to prevent voluntary turnover in teams.     

The money attitude of covert and overt narcissists

The money attitude of covert and overt narcissists was studied. Both covert and overt narcissism predicted the power-prestige dimension of money attitude, which were both mediated by the need for social power. Interestingly, the relationship for covert narcissism was also mediated by the fear of negative social evaluation, confirming its socially vulnerable and hypersensitive features. In addition, the anxiety and distrust factors of money attitude were correlated with covert narcissism only. Anxiety was explained by the need for power and avoidance motivation, but no significant mediator was found for distrust. These findings provide evidence to the similarities and differences between the two types of narcissism. They also shed light on narcissists’ money-related behaviors, such as investment strategy and consumer behaviors.     

心理预期与认知方式对负面情绪的交互调节

近年来, 研究发现对负性事件发生之前预先的心理准备, 即心理预期, 能有效降低负性事件发生后的情绪影响, 但预期过程本身却导致情绪相关神经环路的激活与主观焦虑体验。因此, 采用适应性认知调节方式克服预期过程本身的负面情绪效应, 以充分发挥事先预期的情绪调控优势, 成为情绪调节领域亟待解决的问题。另一方面, 过度负性预期--对潜在负性事件不仅作负面心理预期同时以情绪化的认知方式应对该事件, 是焦虑障碍的核心特征。因此, 对焦虑症患者进行适应性认知方式的训练以消除其情绪化应对方式, 最终减弱该人群对未知事件的过度负面预期, 可能是焦虑障碍干预的重要途径。因此, 有必要综合行为学, 多导外周生理记录与神经成像手段以揭示认知方式与心理预期对负面情绪的交互调节效应; 旨在探求发挥心理预期情绪调节优势, 减弱其情绪代价的方法; 并为焦虑症的临床治疗提供新的思路。     

小学生领导力萌芽与发展的实证研究

摘 要 本研究以四年级学生为研究对象,通过话语分析,探究了八个无领导小组八次讨论过程中领导力的萌芽状况及其影响因素。结果发现,小学生可自发出现领导力行为,但只有两个小组会涌现出明显的领导者,并表现为独立领导和协同领导两种不同模式。对学生和教师行为的综合分析显示,学生领导力的形成与教师示范、反馈及同伴互动存在密切关系,这对学生领导力的培养具有重要的启示意义。     

Male susceptibility to attentional capture by power cues

The present investigation explores the possibility that power has increased salience among males but not females. Evidence indicates that stimuli that are self-relevant or related to chronic goals are more likely to capture attention than neutral information. Across three studies we explore the possibility that the premium males place on power influences how they attend to their environment. Consistent with the common belief that power more readily captures their attention, results indicate that males “dwell” longer on power-related cues (Experiment 1) and are more subject to distraction by task-irrelevant power cues (Experiment 2) than are females. Experiment 3 demonstrates that this increased salience has enduring social consequences by increasing the likelihood that males commit power-relevant material to memory.     

The development of gyrification in childhood and adolescence

Gyrification is the process by which the brain undergoes changes in surface morphology to create sulcal and gyral regions. The period of greatest development of brain gyrification is during the third trimester of pregnancy, a period of time in which the brain undergoes considerable growth. Little is known about changes in gyrification during childhood and adolescence, although considering the changes in gray matter volume and thickness during this time period, it is conceivable that alterations in the brain surface morphology could also occur during this period of development. The formation of gyri and sulci in the brain allows for compact wiring that promotes and enhances efficient neural processing. If cerebral function and form are linked through the organization of neural connectivity, then alterations in neural connectivity, i.e., synaptic pruning, may also alter the gyral and sulcal patterns of the brain. This paper reviews developmental theories of gyrification, computational techniques for measuring gyrification, and the potential interaction between gyrification and neuronal connectivity. We also present recent findings involving alterations in gyrification during childhood and adolescence.     

垂体腺瘤诊疗过程中应重视对垂体腺瘤患者生命质量评估

垂体腺瘤是一种常见的颅内神经内分泌肿瘤,约占颅内肿瘤的10%～15%,常伴有不同程度的肿瘤占住效应(头痛、视力受损等)、功能性腺瘤引起的激素水平过高和正常垂体受压破坏引起的垂体功能低下等症状,因此多数患者的生命质量受到影响.随着生物-心理-社会医学模式理念的逐步深入,除了关注患者的内分泌紊乱、肿瘤大小以及肿瘤引起的症状外,患者的生命质量也应该受到密切关注.本文将针对国内外对垂体腺瘤患者生命质量评估的相关进展进行综述.     

Investigating the relationship between item exposure and test overlap: Item sharing and item pooling

To date, exposure control procedures that are designed to control item exposure and test overlap simultaneously are based on the assumption of item sharing between pairs of examinees. However, examinees may obtain test information from more than one examinee in practice. This larger scope of information sharing needs to be taken into account in refining exposure control procedures. To control item exposure and test overlap among a group of examinees larger than two, the relationship between the two indices needs to be identified first. The purpose of this paper is to analytically derive the relationships between item exposure rate and each of the two forms of test overlap, item sharing and item pooling, for fixed‐length computerized adaptive tests. Item sharing is defined as the number of common items shared by all examinees in a group, while item pooling is the number of overlapping items that an examinee has with a group of examinees. The accuracy of the derived relationships was verified using numerical examples. The relationships derived will lay the foundation for future development of procedures to simultaneously control item exposure and item sharing or item pooling among a group of examinees larger than two.     

Noncontingent access to preferred sensory stimuli as a treatment for automatically reinforced stereotypy

Researchers have previously suggested that interventions designed to decrease stereotypic behavior are most effective when they include access to stimuli that are matched to the specific sensory consequences hypothesized to maintain the stereotypy. In an attempt to replicate this finding, we used stimulus preference assessments and a reversal design to evaluate the effectiveness of noncontingent access to highly preferred stimuli that were matched to the specific sensory consequences hypothesized to be maintaining the stereotypic behavior of an individual with developmental disabilities. The participant was also given noncontingent access to a highly preferred edible stimulus as a control condition. Results indicated that noncontingent access to a matched sensory stimulus produced consistent decreases in aberrant behavior while access to a highly preferred edible stimulus did not.

A Study on Singaporeans’ Perceptions of Sexual Harassment From a Cross‐Cultural Perspective1

This paper addresses the question of whether culture and language in Singapore affect the interpretation of sexual harassment; that is, whether speakers from a different language and ethnic background will interpret the discourse domain of sexual harassment differently. Three studies constitute this research. The first study investigates whether certain cues relating to sexual harassment are judged equivalently across the ethnic groups. The second study examines how verbal space is conceptualized and ruled by the use of different languages used by different ethnic groups. The third study explores whether English, as a medium of communication, is a low‐context language. Results show that different ethnic groups perceived the cues differently; that ethnicity affects the interpretation of a single English phrase; and that English as used by Singaporeans is a high‐context language, which complicates the understanding of victims’ coping responses.
