When is educational specialization heterogeneity related to creativity in research and development teams? Transformational leadership as a moderator

The authors examined conditions under which teams' educational specialization heterogeneity was positively related to team creativity. Using a sample of 75 research and development teams, the authors theorized and found that transformational leadership and educational specialization heterogeneity interacted to affect team creativity in such a way that when transformational leadership was high, teams with greater educational specialization heterogeneity exhibited greater team creativity. In addition, teams' creative efficacy mediated this moderated relationship among educational specialization heterogeneity, transformational leadership, and team creativity. The authors discuss the implications of these results for research and practice.     

If it goes up, must it come down? Chronic stress and the hypothalamic-pituitary-adrenocortical axis in humans

The notion that chronic stress fosters disease by activating the hypothalamic-pituitary-adrenocortical (HPA) axis is featured prominently in many theories. The research linking chronic stress and HPA function is contradictory, however, with some studies reporting increased activation, and others reporting the opposite. This meta-analysis showed that much of the variability is attributable to stressor and person features. Timing is an especially critical element, as hormonal activity is elevated at stressor onset but reduces as time passes. Stressors that threaten physical integrity, involve trauma, and are uncontrollable elicit a high, flat diurnal profile of cortisol secretion. Finally, HPA activity is shaped by a person's response to the situation; it increases with subjective distress but is lower in persons with posttraumatic stress disorder.     

Adult visual experience promotes recovery of primary visual cortex from long-term monocular deprivation

Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance plasticity in rodents, led us to re-examine whether adult primary visual cortex (V1) is capable of any recovery following long-term monocular deprivation starting in development. Using mice as a model, we find that monocular deprivation from early development to mature ages (well past the critical period) severely impaired binocular vision by reducing the amplitude of responses elicited by stimulation of the deprived eye. Surprisingly, we find little effect on nondeprived eye responses. Restoration of binocular vision in mature adults yields modest but significant improvement of visual responses in V1. Remarkably, we find that when binocular vision is followed by occlusion of the nondeprived eye, visual responses in V1 recover almost fully, as measured by visual evoked potential amplitude, spatial frequency threshold, and single-unit activity. We conclude that adult V1 can recover from long-term deprivation when provided with an optimal regimen of visual experience.     

中国社会现代化进程和城市现代化水平 与中国人群体人格变化模式

再利用本土化的人格工具CPAI,对中国社会现代化发展时间进程和城市现代化水平差异与中国人群体人格特征模式之间的关系进行了探讨。研究结果表明,中国人的群体人格特征正在随着社会发展而成现出相应的变化,表现为更为多元化、个性张扬、人际关系的束缚在减弱。当然,现代化进程的时间和空间特征对人格变化的影响可能存在差异性。因此,在研究社会发展与人格间关系时,应该同时关注社会变迁的时间与空间两个维度。研究显示,随着中国社会的发展,具有开放性、多样性人格特征的新一代中国人正在形成过程中,他们反过来也会对中国的现代化进程产生影响     

公平敏感性研究述评

公平敏感性是基于对Adams公平理论的批评提出来的,反映的是人们在公平问题上的个体差异性。该文首先对公平敏感性概念的提出与修正进行了回顾,并介绍了公平敏感性的测量方法和分类标准;然后分析了公平敏感性对于结果变量的直接及调节效应,个人及社会文化因素对公平敏感性的影响,并介绍了公平敏感性的跨文化比较;最后指出该领域未来的研究应着重澄清对概念理解的差异,改进分类标准,加强对公平敏感性影响因素以及中国人公平敏感性的研究     

态度强度的维度结构与研究操作

态度强度指态度具有坚持性和抵抗性的程度及其对信息加工过程和行为产生影响的程度,包括可获得性、两面性、确定性、精细加工、极端性、重要性、知识性、个人相关性和结构一致性9个常见维度。文章介绍了态度强度的操纵和测量方法,对探讨态度强度维度结构的已有研究进行了阐述和总结,在此基础上指出态度强度至少包含三重维度结构,并提出将态度强度与群体水平变量和社会预警系统相联系等研究角度     

父母-儿童共同活动中的互动与儿童的数学学习

本研究运用结构性观察方法对两组4岁儿童与父母在四种活动中的互动进行了分析与比较。一组儿童为书面数符号测查高分者,二组儿童为书面数符号测查低分者。85对父母一儿童对子参加了4个各有15分钟的共同活动,阅读、数学题、纸和积木,并完成一个微型问卷。结果表明,在这些活动中包含了多种数学知识学习和多种以父母为主导的互动策略;两组对子之间在数学事件频次上无差异,但一组父母更多地运用了一些积极策略,二组父母更多地运用了一些消极策略;二组中有更多儿童对互动表现出消极回应和注意力问题。两个组的父母在家中与儿童一起进行诸如阅读和做数学题的共同活动的频次与质量上表现出差异。     

网络使用线索对不同动机使用者上网欲望的诱发作用

以67名信息获取性动机者和54名人际情感性动机者为被试,以基于实景照片的网络信息获取线索、网络情感满足线索和负性情绪线索为刺激材料,采用线索暴露范式探讨了网络使用线索对网络使用者上网欲望的相对影响。实验结果表明,网络信息获取线索仅对信息获取性动机者的上网欲望具有显著的诱发作用,而情感满足线索和负性情绪线索仅对人际情感性动机者的上网欲望具有显著的诱发作用。该研究为解释人际情感性动机者的病理性互联网使用行为特征提供了实验证据。     

When openness to experience and conscientiousness are related to creative behavior: an interactional approach.

This study adopted an interactional approach to understanding how 2 of the Five-Factor traits, openness to experience and conscientiousness, are related to creative behavior in the workplace. Openness to experience is theorized to result in high levels of creative behavior and conscientiousness is theorized to result in low levels of creative behavior when the situation allows for the manifestation of the trait influences. More specifically, the authors hypothesized that openness to experience would result in high levels of creative behavior if feedback valence were positive and job holders were presented with a heuristic task that allowed them to be creative. The authors also hypothesized that conscientiousness would result in low levels of creative behavior if supervisors engaged in close monitoring and coworkers were unsupportive. The authors tested their hypotheses in a sample of office workers, and 5 out of the 6 hypotheses were supported.     

多维效标测量的构成
