Money versus pain: experimental study of a conflict in humans.

Ten healthy human males volunteered to be subjects in an experiment in which they were to be paid to endure a painful sensation. This sensation was produced by isometric muscular contraction in the thighs. For each of six sessions the subjects received either a payment that was changed for each session (0.2, 0.5, 1.25, 3.125, 7.8125 French francs per 20 s) or a lump sum. At the beginning of a session, the subjects assumed a seated position against a wall, but without a seat, and the duration for which they could hold this position was the chief variable measured. Heart rate, blood pressure, and magnitude estimation of pain were also recorded periodically throughout each session. Pain was reported after a mean delay of 15 +/- 7 s (SE), and the magnitude estimates then increased linearly with time. The duration of maintaining the painful position increased linearly in relation to the logarithm of the increase in the amount of payment. Thus, utility of money decreased when pitted against pain.     

前扣带回功能的冲突监测理论

前扣带回在多种任务中的普遍激活使它成为当前认知控制研究的一个热点。一般认为它是执行控制网络的一个组成部分。针对它的功能尚缺乏一个综合的可以普遍接受的理论,前扣带回功能的冲突监测理论是一个影响十分广泛的理论。它认为前扣带回通过监测冲突提供控制信号,并将控制信号传达给具体负责控制的脑区。该文对冲突监测理论的观点及其实验支持做了简要的介绍,并对该理论存在的一些问题做了一些说明     

权威人格与权力感对道德思维方式的影响

本研究考察了在一个道德两难的情境中, 权威人格和权力感对道德思维方式的影响。研究以某市公检法系统的122名公务员为被试。首先采用权威人格问卷筛选出高权威人格组和低权威人格组被试, 然后分别进行高、低权力感的启动, 最后让被试对一个道德上的两难情景做出选择, 选择的结果可以反映被试的道德思维方式。研究结果显示, 高权威人格组被试在启动了他们高的权力感后, 产生了明显的以规则导向为主的道德思维, 而对低权威人格被试, 他们道德思维方式则不受权力感启动的影响。由于社会冲突的产生常常与冲突情境中的道德思维方式有关, 因此本研究的结果有助于我们更好地理解某些社会冲突产生的原因, 并从心理学的角度提出解决冲突的方法。     

Studying the role of cognitive control in reasoning: evidence for the congruency sequence effect in the ratio-bias task

In this study, we investigated whether control of the conflict between incongruent heuristic and analytical answer options in a reasoning task is modulated by the presence of conflict on previous trials. In two experiments, we found that the incongruency of the previous trial has a significant effect on the control exhibited on the current trial. Our data also showed that this adaptation effect is modulated by the incongruency of the previous series of trials. These results demonstrate the same control adaptation effects for a reasoning task as observed for standard response interference tasks. Coinciding control effects in the two research areas suggest that cognitive control might be an important mechanism underlying performance on reasoning tasks. Based on these results we argue that the study of cognitive control in reasoning could potentially facilitate the refinement of empirical predictions and provide a new tool to explore the exertion of top-down control in human thinking.

Positive and negative effects of family involvement on work-related burnout

We aimed to explain the influence of family involvement on feelings of burnout among employees who combine work and family tasks. As proxies for family involvement, we used the family structure (partner, number and age of children) and family tasks (e.g. hours spent on household chores). We compared conflict theory and enrichment theory, and investigated how well they explain the relationship between family involvement and feelings of burnout. Based on a sample of 1046 employees at 30 Dutch organizations, the results showed that the presence of young children and doing more household chores were positively related to feelings of burnout, whereas having children reduced employees’ feelings of burnout. We also investigated interaction effects of gender and gender-role norms. We conclude that family life can reduce work-related burnout and that for men, the relationship between family involvement and feelings of burnout differs depending on whether they have traditional or modern gender-role norms.

Social support from work and family domains as an antecedent or moderator of work-family conflicts?

On the basis of Conservation of Resources theory, we investigated how social support from supervisor, co-workers, life partner, and family members is associated with work-family conflicts in N = 107 working mothers. We used data from a cross-sectional questionnaire and a standardized diary to examine two possible forms of interplay: (a) Social support as an antecedent of work-family conflicts, and (b) moderating effects of social support on the relationship between domain-specific strain and work-family conflicts. Overall, results favored social support as an antecedent of work-family conflicts.     

Socio-cognitive conflict, emotions and complexity of thought in real-life morality

A new taxonomy of real-life dilemmas was tested in two studies. In Study 1, 35 respondents assessed six types of real-life dilemmas in terms of socio-cognitive conflict. Support was found for a classification of dilemmas into three levels of socio-cognitive conflict. In Study 2, 191 young women responded to measures of social perspective-taking and emotional empathy and reported a real-life moral dilemma as well as their feelings while making decisions about it. The dilemmas were classified into personal and impersonal and into three levels of socio-cognitive conflict. Dependent variables were the integrative complexity of the arguments and the reported feelings (sympathy, upset, and remorse). Dispositional empathy and perspective taking predicted level of socio-cognitive conflict and feelings of sympathy but not integrative complexity. Personal dilemmas aroused more feelings of upset than did impersonal ones. Low socio-cognitive conflict dilemmas evoked less complex thinking and less intensive feelings of upset and sympathy than did moderate and high socio-cognitive conflict dilemmas.
