How do supporters perceive positive and negative psychological momentum changes during a simulated cycling competition?

ObjectiveThe present study examined changes in sport supporters' psychological momentum (PM) during a simulated cycling competition through the lens of the dynamical systems approach.DesignParticipants were asked to support one of two competing cyclists involved in a race that was displayed on a screen in a lecture hall.MethodThe race scenario was manipulated so that the image of the supported cyclist underwent either positive or negative momentum. At regular intervals, participants indicated their PM perceptions during the race.ResultsPM perceptions rapidly changed at the onset of both the positive and negative momentum sequences and then remained stable, reflecting negative hysteresis. Supporters tended to anticipate the future performance of a given athlete on the basis of their current performance. Moreover, this anticipatory tendency was stronger during the positive momentum sequence than during the negative momentum sequence.ConclusionThese results provide initial insights into how PM perceptions of sport supporters change during a competition.     

Racers,Pacers, Gender and Records: On the Meaning of Sport Competition and Competitors

This paper examines footraces that are paced and unpaced, and runners who are pre-arranged, designated pacers and those who are not. Although pacesetting is commonplace in footraces today, the practice challenges our conception of sport competition, the nature of competitors and the meaning of records. For example, Bale calls paced races as ‘staged experiments’ to set world records and argues that pacers were crucial in the running career of Roger Bannister. In 2011, the International Association of Athletics Federation (IAAF) banned women’s world records in mixed gender running events, like major marathons, because women were paced by male runners. By examining these cases and others, the authors here will claim paced footraces are qualitatively different than unpaced competitions, pacers introduce peculiar motives and intentions as competitors, women should not be denied opportunities to excel and perform at their very best, and the 2011 IAAF policy is unjustified.     

图词间隔时间影响口语词汇产生中语义效应的机制：图词干扰范式研究

口语词汇产生过程中存在语义抑制和语义促进效应, 可能发生在概念准备和词汇选择或者后词汇水平阶段。本研究采用图画-词汇干扰实验任务, 变化图画与词汇出现点之间的时间间隔(stimulus onset asynchrony, SOA), 运用脑电技术考察口语词汇产生中语义效应发生的时间进程。结果显示, 当SOA为0 ms时表现出语义抑制效应, 语义效应发生在词汇选择阶段(344~418 ms); 当SOA为-400 ms时, 语义效应发生在概念准备阶段(0~76 ms)和词汇选择阶段(274~390 ms); 460~594 ms时间窗口内的语义效应可能表明讲话者对语义信息的自我监测。词汇产生中存在语义促进效应和抑制效应的权衡, 影响了行为结果中语义效应的方向, 上述发现支持了口语词汇产生的词汇竞争假说。     

语音控制加工经验有助于促进语音执行控制功能

来自双语的研究表明,双语者在抑制、转换、注意力维持等执行控制功能方面较之于单语者具有显著的认知优势效应。该效应是双语者对诸多语言亚成分协同控制的结果,还是对不同语音体系控制的结果,目前依然存在争论。本研究以单语单言儿童（仅会说汉语普通话）和单语双言儿童（同时会使用汉语普通话和泰州方言）为被试,通过线索-切换任务和语音Stroop任务就上述问题进行了研究。结果显示：（1）在线索-切换任务上,两组儿童作业表现差异不显著;（2）在语音Stroop任务上,单语双言儿童具有显著的认知优势。据此,本研究认为双语认知优势的获得是个体对诸如句法、语义、正字法、语音、词素等多种语言亚成分协同控制的结果。     

语义关联性对重复知盲效应的影响：来自汉语成语的证据

重复知盲是在快速系列视觉呈现任务中对第二个重复刺激的加工缺陷。以汉语中反义字和成语为实验材料,采用全部报告任务,探讨刺激的语义关联性对重复知盲的影响。实验1以汉语单字为材料,采用单因素三水平（目标刺激之间的语义关系：无关、相同、相反）被试内设计,结果是重复字产生重复知盲效应,反义字产生语义启动效应。实验2以成语为材料,采用2（目标刺激之间的语义关系：相同、无关）×2（位置：前位置、后位置）设计,结果是语义关联性消解了重复知盲效应。结果表明：（1）反义字不产生重复知盲效应。（2）语义关联性消解成语中重复字的重复知盲效应。（3）实验结果支持竞争假设。     

Importance of considering testosterone-cortisol interactions in predicting human aggression and dominance

A novel "field" study recently published in Aggressive Behavior found that individual differences in baseline testosterone concentrations were positively correlated with endorsement of political aggression and that baseline cortisol concentrations were negatively correlated with self-reported aggression among Palestinian boys living in Gaza. Here, we discuss recent evidence indicating that testosterone and cortisol interact to predict competitive, aggressive, and dominant behaviors and urge researchers collecting both hormones to perform and report analyses that formally test for such interaction effects.     

Extending the Theory of Realistic Conflict to Competition in Institutional Settings: Intergroup Status and Outcome

Abstract

The authors analyzed the extent to which the Theory of Realistic Conflict can be extended to institutional settings in which groups are not actively involved in decisions but are passive targets of decisions taken by an institutional authority (the rector). A negative interdependence between the in-group (psychology) and a high- or low-status out-group (engineering versus nursing) was established by an institutional authority (the rector). The competition (induced by the rector) was beneficial (an increase in the budget previously invested in the faculty) or detrimental (a decrease in the budget) for the in-group. The results confirmed that competition affects mutual attitudes, images, and behaviors of groups even if the groups are passive targets of decisions that the institutional authority makes. Moreover, competition—regardless of whether beneficial or detrimental—deteriorated images of and attitudes toward high-status out-groups. In contrast, competition improved images and opinions about low-status out-groups, but only in the loss condition.     

Developing work–family balance through conflict management*

An often‐neglected perspective is that work–family incompatibilities are not only intrapersonal role conflicts but also typically involve interpersonal conflicts. This study adopts an episodes approach and uses the theory of cooperation and competition to understand the interaction that promotes resolving work–family conflict incidents. Two‐hundred and four Chinese dual‐career parents each described a specific work–family conflict incident and responded to specific questions to code the interaction. Structural equation analyses indicated that cooperative goals facilitated constructive controversy that in turn promoted high quality resolutions, strong relationships, and confidence in the future of their work and family lives.     

特殊的视错觉：运动诱导视盲

突显的静止目标被一定空间范围内运动背景所覆盖时, 人类会感受到静止目标消失再重现的发生, 这种视错觉现象叫做运动诱导视盲(motion-induced blindness, MIB)。该现象成因的理论解释主要有：注意竞争理论、知觉完型加工理论以及神经生理机制相关理论。作为特殊的视错觉现象, 该现象与其他盲视现象不同,主要是由客体识别过程中的知觉变化引起; 另一方面, 运动诱导视盲中“反知觉”现象的特殊性也是研究者关注的问题之一。神经生理机制层面的研究关注早期、晚期皮层在该现象发生时的变化, 采用眼动、脑电等技术对错觉现象发生时程进行测量与评估。文章在总结已有相关研究的基础上进一步指出今后可深入探索的研究方向有：MIB发生的深层机制、作为研究意识神经相关、无意识知觉加工等课题的工具、MIB中的意义性加工与认知冲突等。     

高绩效要求与亲组织不道德行为:基于社会认知理论的视角

通过确立较高的绩效目标以提升组织绩效被普遍认为是一项有效的管理措施。然而,学术界对它的负面影响却缺乏研究。本文提出了高绩效要求将启动员工道德推脱机制为其随后进行的亲组织不道德行为开脱,即道德推脱在高绩效要求与亲组织不道德行为之间起到了中介作用。为了检验这一观点,本研究提出两种不同效应的调节变量:感知的市场竞争正向调节变量之间的间接关系,而道德认同则负向调节这一间接关系。通过对某零售企业225名员工的两阶段调查,本研究提出的调节-中介模型获得了观察数据的支持。本研究的发现有利于进一步了解亲组织不道德行为发生的中介心理机制和边界条件,指导管理者采取恰当的管理措施,以期有效地管控亲组织不道德行为的出现。
