Anger and happiness in virtual teams: Emotional influences of text and behavior on others’ affect in the absence of non-verbal cues

Emotions carry social influence, as evident by emotion contagion - an unconscious process attributed to mimicking of non-verbal cues. We investigate whether emotion contagion can occur in virtual teams; specifically, the emotional influence of text-based and behavior-based cues on participants’ emotion in 4-person virtual teams. In a 2 × 2 design a confederate textually communicated anger or happiness, while behaving in a resolute or flexible pattern. The team task required negotiation offering a performance based reward. We demonstrate that emotion contagion occurs in teams even when communication is only text-based. We show that behaviors are perceived as emotionally charged, resolute behavior interpreted as a display of anger, and flexibility as a display of happiness. Moreover, we demonstrate that incongruence between text-based communication of emotion and emotionally charged behaviors elicits negative emotion in fellow teammates. Our findings extend the boundaries of emotion contagion and carry implications for understanding emotion dynamics in virtual teams.     

儿童对情绪表达规则的理解与策略的使用

从一所普通小学一三五年级学生中选取90名被试,结构访谈法考察儿童对情绪表达规则的理解与表达策略的使用。结果表明,儿童对情绪表达规则的理解在一到三年级阶段获得快速发展,三到五年级变化很小,而且在积极和消极情境下发展趋势比较一致,但性别和情境交互作用显著。不同年级儿童对策略的使用表现出类似对情绪表达规则理解的变化趋势,全部被试中,平静化策略使用最多,掩饰策略次之,在掩饰策略的使用上,性别和情境交互作用显著。     

啮齿动物主动母性行为动态改变的神经机制

主动母性行为是雌性哺乳动物在哺乳期内有效照料幼崽的一种动机行为, 对幼崽的生存和行为发展有重要影响。证据显示, 啮齿动物的主动母性行为会经历从产后早期的发动和维持到晚期衰退的动态改变, 反映了雌鼠对幼崽奖赏价值阶段性变化的适应; 这一过程不仅涉及分娩激素事件开启下丘脑内侧视前区(MPOA)-中脑腹侧被盖(VTA)-伏隔核(NA)-腹侧苍白球(VP)通路, 还需要杏仁核基底外侧核(BLA)和内侧前额皮层(MPFC)等脑区对上述通路进行实时调节。哺乳期主动母性行为动态改变及其神经机制的研究, 可以加深对行为进化和早期发展的认识, 也对人类母亲产后抑郁等临床问题的干预有借鉴意义。本文首先利用条件化位置偏好(CPP)任务的行为学证据分析幼崽奖赏价值与主动母性行为动态改变的关系; 然后系统阐述调控这一动态改变的神经机制; 最后对未来需要研究的一些重要问题或方向进行探讨。     

A Prospective Analysis of Near-Death Experiences in Cardiac Arrest Patients

The objective of this study was to assess prospectively the frequency of near-death experiences (NDEs) in patients suffering a cardiac arrest, to characterize these experiences, and to assess their impact on psychosocial and spiritual attitudes. We prospectively evaluated all patients who suffered a cardiac arrest at Barnes-Jewish Hospital from April 1991 through February 1994, excluding those in the surgical intensive care unit, using a scale designed to specify criteria for NDEs, a recorded interview regarding the experience, an experience rating form, and a follow-up questionnaire regarding psychosocial attitudinal life changes. Of the 174 patients who suffered a cardiac arrest, 55 patients survived, of whom 30 patients were interviewable. Of those 30 patients interviewed, seven (23 percent) had a NDE, and four others (13 percent) reported an NDE during a prior life-threatening illness. The experiences were most frequently characterized by ineffability, peacefulness, painlessness, lack of fear, detachment from the body, and no sense of time or space. Significant differences were noted in the follow-up psychosocial assessment between patients who experienced an NDE and those who did not with regard to personal understanding of life and self, attitudes toward others, and changes in social customs and religious/spiritual beliefs. Of importance, patients reported it was beneficial to receive psychosocial support before hospital discharge after having an NDE. The results suggest that NDEs are fairly common in cardiac arrest survivors. The experiences consisted of a number of core characteristics and changed psychological, social, and spiritual awareness over both the short and long term.     

中小学生交往归因训练的研究

从普通学校选取小三、初二、高二各两个平行班的学生,采用等组对照设计,一为实验班,一为控制班。研究分前测验、教育干预、后测验三个阶段。结果发现：(1)归因训练可使学生的交往成败归因向积极方面转化。(2)归因训练可提高学生对未来交往成功的期望值。(3)短时间内的归因训练对高中生影响不大。     

Age-related differences in learning disabled and skilled readers' working memory

This study determines whether age-related deficits in learning disabled (LD) readers' working memory performance reflect delays in retrieval efficiency and/or storage capacity. The study compared LD and skilled readers' working memory performance (N=226) across four age groups (7, 10, 13, and 20) for phonological, visual-spatial, and semantic information under initial (non-cued), gain (cues that bring performance to an asymptotic level), and maintenance conditions (asymptotic conditions without cues). The important results were that LD readers' working memory performance was inferior to skilled readers on verbal and visual-spatial working memory tasks across all age groups and these differences increased on gain and maintenance conditions when compared to initial conditions. These reading group differences remained when age, reading, and mathematics were partialed from the analysis. The results support a general capacity explanation of reading group differences that is not totally dependent on reading skill. These differences in capacity reflect demands placed on both the accessing of new information and the maintenance of old information that extend beyond the phonological system.     

Technologies émergentes et transformations digitales de l’activité : enjeux pour l’activité et la santé au travail

The question of the introduction of emerging technologies and their incessant renewal in organizations basically refers to the place and role that these devices play in activity, as well as how they can affect activity and health at work … Thought as a prospective reflection trying to grasp the logic and the modalities of the digital transformations in progress, the ambition of this paper is: (i) first, identify and characterize the emerging technologies that are deployed in the company; (ii) discuss their impact on the activity and well-being of employees, showing the uses and paradoxical effects that these devices can have on work; and (iii) finally think about the psychosocial function of these devices as potential health and business development operators.     

Habituation contributes to within-session changes in free wheel running.

Three experiments tested the hypothesis that habituation contributes to the regulation of wheel running. Rats ran in a wheel for 30-min sessions. Experiment 1 demonstrated spontaneous recovery. Rats ran more and the within-session decreases in running were smaller after 2 days of wheel deprivation than after 1 day. Experiment 2 demonstrated dishabituation. Running rate increased immediately after the termination of a brief extra event (application of the brake or flashing of the houselight). Experiment 3 demonstrated stimulus specificity. Rats completed the second half of the session in either the same wheel as the first half, or a different wheel. Second-half running was faster in the latter case. Within-session patterns of running were well described by equations that describe data from the habituation, motivation, and operant literatures. These results suggest that habituation contributes to the regulation of running. In fact, habituation provides a better explanation for the termination of wheel running than fatigue, the variable to which this termination is usually attributed. Overall, the present findings are consistent with the proposition that habituation and sensitization contribute to the regulation of several forms of motivated behavior.     

篇章阅读理解中背景信息的通达

该研究采用实时窗口阅读技术探讨篇章阅读理解中背景信息的通达机制。在该研究所用的阅读材料中,主人公特征与目标句行为分别形成一致、冲突与冲突限制三种关系,其中,冲突限制条件下既描述了主人公与目标行为有所冲突的特征,但这些特征要么是主人公过去具有的、要么是虚假的,在此基础上,阅读材料又提供了主人公当前的、与目标句行为一致的特征描述。结果发现,不论把冲突限制条件下的冲突信息限制在过去发生,还是作为一种虚假的情况来加以描述,都不能完全消除冲突的效应,冲突限制条件下目标句阅读时间总是长于一致条件下的阅读时间,这支持了记忆基础文本加工观,说明在篇章阅读中背景信息通达不是一个更新追随的过程,过去的或虚假的背景信息也会被重新激活并影响当前信息的加工。     

Effects of post-session wheel running on within-session changes in operant responding

This study tested the effects of post-session wheel running on within-session changes in operant responding. Lever-pressing by six rats was reinforced by a food pellet under a continuous reinforcement (CRF) schedule in 30-min sessions. Two different flavored food pellets were used as reinforcers. In the wheel conditions, 30-min operant-sessions with one of the flavored pellets were followed by 30-min free-wheel running sessions. Meanwhile, in the home conditions, rats’ operant responding was reinforced by the other flavored pellets during 30-min operant-sessions, and the rats were then returned to their homecages. All rats were exposed to 4 wheel and 4 homecage sessions. Operant responding was lowered during the wheel conditions. However, post-session running did not alter the within-session pattern of operant responding. These effects were practically identical to the effects of drug-induced taste-aversion learning on within-session changes in operant responding, suggesting similar mechanisms in both taste-aversion preparations.
