冲突对绩效的影响：个体、团队宜人性的调节作用

以往个体和团队冲突研究主要考察了个人特征或团队特征对冲突结果的影响, 而尚未充分关注冲突管理过程中个体特征与团队特征间的交互效应。基于个人-团队匹配理论, 本研究探讨了个体层面宜人性与团队层面宜人性异质性对团队中个体冲突(关系冲突、任务冲突)和工作绩效间关系的影响。基于来自64个银行服务团队(包含339名下属和64名主管)的多来源、多时点纵向数据, 本研究所得结果显示：(1)关系冲突显著负向影响工作绩效, 任务冲突对工作绩效的影响不显著。(2)个体宜人性能够显著减弱关系冲突对工作绩效的负面影响, 而增强任务冲突对工作绩效的正向影响。(3)关系/任务冲突、个体宜人性和团队宜人性异质性间存在着三重交互效应, 共同影响工作绩效。具体而言, 当团队宜人性异质性水平较低时, 个体宜人性对关系/任务冲突与工作绩效间关系的调节作用更加显著。     

材料因素对学习判断及其孤立效应的影响

通过三个实验考察材料特有的内在因素差异对学习判断及其孤立效应的影响,选取814名的高一学生作为被试,男女各半。实验一是探讨性质不同的孤立项目对学习判断及其孤立效应的影响;实验二是探讨层次差异不同的同质项目对学习判断及其孤立效应的影响;实验三是探讨孤立项目的序列位置对学习判断及其孤立效应的影响。结果表明:在不同材料中,材料的性质的差异越大,孤立效应越显著,证明了孤立材料的距离效应;在同质材料中,材料内部层次差异越大,孤立效应越显著,证明了孤立材料的幅度效应;在学习判断中,不管孤立项目的序列位置处于前位还是后位,都存在孤立效应,且材料中孤立项目的位置越靠后面,其孤立效应就越明显,证明了孤立材料的后位效应。     

Instrument specificity in experienced musicians

Previous studies have shown that experienced pianists have acquired integrated action-effect (A-E) associations. In the present study, we were interested in how specific these associations are for the own instrument by investigating pianists and guitarists. A-E associations were examined by testing whether the perception of a “potential” action-effect has an influence on actions. Participants played chords on their instrument in response to visual stimuli, while they were presented task-irrelevant auditory distractors (congruent or incongruent) in varying instrument timbre. In Experiment 1, pianists exhibited an interference effect with timbres of their own instrument category (keyboard instruments: piano and organ). In Experiment 2 guitarists showed an interference effect only with guitar timbre. Thus, integrated A-E associations primarily seem to consist of a specific component on a sensory-motor level involving the own instrument. Additionally, categorical knowledge about how an instrument is played seems to be involved.     

Tool characteristics in imagery of tool actions

Are tool characteristics represented in imagined tool actions? In two experiments participants imagined and executed coloring rectangles with a thick and a thin pen. In Experiment 2, an additional execution condition without visual feedback of coloring allowed us to dissociate between the relevance of kinesthetic and visual feedback. Pen thickness influenced coloring durations in all conditions, indicating that characteristics of a simple tool are represented during imagery. Imagination was shorter than execution, indicating that imagination may be less detailed than execution. Execution without visual feedback was even shorter than imagination, indicating that vision is more important than kinesthesis for differences between imagination and execution, and that either imagining the movement, inhibiting movement execution or imagining the progress of the action is effortful during imagery. In conclusion, characteristics of simple tools are represented in imagined tool actions but the representation of tools’ effects may not always be adequate.     

晚期乳腺癌外科治疗的时机与个体化选择

IV期乳腺癌是难以治愈的疾病,治疗方法是综合治疗,目的是缓解症状、改善生活质量、延长生存期。外科治疗作为综合治疗的一部分,对手术切除Ⅳ期乳腺癌原发灶或转移灶的临床意义和手术时机存在争议,本文结合文献从哲学的角度分析讨论Ⅳ期乳腺癌是否需要外科处理。认为Ⅳ期乳腺癌全身治疗和外科治疗是治疗过程中矛盾主要方面和次要方面的关系,可互相转化,两者作用相辅相成,当全身治疗病情缓解时,个体化选择外科治疗不仅改善生存质量,还可能提高生存率。     

分析思维对冲动购买意向影响的研究

采用三个研究探讨分析思维对冲动购买意向的影响。研究1以146名大学生为被试,采用分析思维任务和冲动购买意向问卷,考察分析思维与冲动购买意向的关系;研究2招募了65名大学生被试,研究3招募了62名大学生被试,分别通过视觉启动和组词任务启动两个范式探讨启动分析思维对冲动购买意向的影响。结果发现,分析思维与冲动购买意向显著负相关,无论是视觉还是组词启动分析思维都能减少冲动购买意向。     

Target- and effect-directed actions towards temporal goals: Similar mechanisms?

The goal of an action can consist of generating a change in the environment (to produce an effect) or changing one's own situation in the environment (to move to a physical target). To investigate whether the mechanisms of effect-directed and target-directed action control are similar, participants performed continuous reversal movements. They either synchronized movement reversals with regularly presented tones (temporal targets) or produced tones at reversals isochronously (temporal effects). In both goal conditions an irrelevant goal characteristic was integrated into the goal representation (loudness, Experiment 1). When targets and effects were presented within the same reversal movement, similarities were enhanced (Experiment 2). When the task posed spatial demands in addition to temporal demands, target- and effect-directed movement kinematics changed equally with tempo (Experiment 3). Correlations between target-directed and effect-directed movements in temporal variability indicated similar timing mechanisms (Experiments 1 and 2). Only gradual differences between target- and effect-directed movements were observed. We conclude that the same mechanisms of action control, including the anticipation of upcoming events, underlie effect-directed and target-directed movements. Ideomotor theories of action control should incorporate action targets as goals similar to action effects. (PsycINFO Database Record (c) 2012 APA, all rights reserved).     

A comparison of eating, exercise, shape, and weight related symptomatology in males with muscle dysmorphia and anorexia nervosa

In the context of the lack of nosological clarity surrounding muscle dysmorphia, this paper aims to compare the symptomatic profile of muscle dysmorphia and anorexia nervosa in males whilst using measures sensitive to indexing male body image concerns. Twenty-one male muscle dysmorphia patients, 24 male anorexia nervosa patients, and 15 male gym-using controls completed the Eating Disorder Examination-Questionnaire, the Muscle Dysmorphia Disorder Inventory, the Compulsive Exercise Test, and a measure of appearance-enhancing substance use. Men with muscle dysmorphia and anorexia nervosa demonstrated widespread symptomatic similarities spanning the domains of disturbed body image, disordered eating, and exercise behaviour, whilst differences were consistent with the opposing physiques pursued in each condition. Furthermore, correlational analyses revealed significant associations between scores on muscle dysmorphia and eating disorder measures. The present findings provide moderate support for the notion that muscle dysmorphia may be nosologically similar to anorexia nervosa.

The inspired time traveler: examining the implications of nostalgic entertainment experiences for two-factor models of entertainment

ABSTRACT

Two studies investigated the characteristics of nostalgic entertainment experiences. A survey (Study 1) asked American undergraduates to report their cognitive and affective reactions during a recent entertainment experience that they deemed nostalgic, meaningful, or pleasurable. Results indicated that nostalgic experiences often occurred after exposure to familiar media content (e.g., beloved children’s shows). Although these experiences were affectively similar to both pleasurable entertainment experiences (in terms of enjoyment) and meaningful entertainment experiences (in terms of mixed affect), they differed in the focus of their associated cognitions (i.e., reflection on the self in the past and over time). A follow-up experiment (Study 2) demonstrated that exposure to familiar children’s shows (rather than unfamiliar children’s shows or meaningful film trailers) induced nostalgic reactions in adults ranging in age from 19 to 47. The implications of these findings for current two-factor models of entertainment are discussed.
