基于虚拟博弈任务对冒犯者得到宽恕后行为的研究:人格的调节作用

为探讨人格特质对得到宽恕与否与冒犯者后续行为之间关系的影响,基于虚拟的囚徒困境博弈范式,并结合人格问卷的测试,对369名大学生进行了研究。结果发现:(1)宽恕情境下的被试更倾向于不再伤害对方;(2)得到宽恕的程度与冒犯者善待对方的程度呈显著的正相关;(3)大五人格中的宜人性在得到宽恕与否与冒犯者后续行为之间关系中起调节作用,而大五人格的其他四个维度调节作用不显著;(4)特质性感恩在得到宽恕与否与冒犯者后续行为之间关系中起调节作用。据此可得出结论,冒犯者得到宽恕后更倾向于不再伤害被冒犯者,且受到部分人格特质的调节。     

最简群体范式的操作、心理机制及新应用

最简群体范式作为研究群际关系的有效工具,受到社会心理学家广泛重视。除经典任务程序、随机分配程序外,新近发展出想象程序、记忆程序、自我卷入、计算机模拟群体互动模式等分类操作。最简群体范式具有随机性、完全匿名性和无关自我功利性等特点,可以从群体推断自我、自我推断群体及社会认同整合三个视角解释其心理机制。目前,最简群体范式在社会认知加工、社会心理偏好、社会互动行为及神经生理反应等领域开始广泛应用。     

(Re)assembling Natures,Cultures, and (Nano)technologies in Public Engagement

Abstract

Practices of ordering are powerful means of giving structure to people's lives and providing a sense of control. The analysis of three episodes from discussion groups on nanotechnology in Austria shows that citizens evaluate new technologies with regard to how they intersect with, support, or disturb existing orders. The concept of discursive assemblages serves as a lens for recognising the non-fixed character of the discursive process, while still allowing the analyst to identify how specific elements, such as conceptions of nature, culture, and technology, are (re)assembled at particular moments. Each of the three episodes represents a specific way of creating and negotiating assemblages: the first case demonstrates how discussants collectively discuss a nature–technology hybrid (nano-bamboo socks) against the backdrop of a highly valued ideal of keeping ‘the natural’ and ‘the technological’ separate; the second episode exemplifies a clash of two assemblages as participants argued for or against the application of nanotechnology in food products; and the third example illustrates the process of collective experimentation with different assemblages to make sense of a highly futuristic nanochip for brain enhancement. Together the episodes demonstrate that participants in public engagement settings do not address nanotechnology as a simple question of choice between acceptance and rejection but rather engage in processes of care regarding how a society might develop when technological innovations such as nanotechnology threaten to blur existing boundaries and orders, such as the distinction between nature and culture.     

元认知监控的机制:认知灵活性的调节作用

元认知监控作为元认知的核心成分,是内隐程度较高的心理活动。研究采用认知操作法,以MasterMind游戏任务为载体,从执行功能中认知灵活性的角度,探讨了元认知监控的内部机制。结果发现:元认知监测对元认知控制的作用受到认知灵活性的调节作用。对于高认知灵活性的学生,元认知监测水平越高,元认知控制越好;对于低认知灵活性的学生,元认知监测水平的高低不会引起元认知控制水平的显著变化。研究结果表明,高认知灵活性的学生能根据元认知监测进行有效元认知控制,而低认知灵活性的学生其元认知监测水平的提高没有影响元认知控制。结合元认知监控与执行功能进行了讨论。     

How to Model Heterogeneity in Costly Punishment: Insights from Responders' Response Times

We investigate what processes may underlie heterogeneity in social preferences. We address this question by examining participants' decisions and associated response times across 12 mini‐ultimatum games. Using a finite mixture model and cross‐validating its classification with a response time analysis, we identified four groups of responders: one group takes little to no account of the proposed split or the foregone allocation and swiftly accepts any positive offer; two groups process primarily the objective properties of the allocations (fairness and kindness) and need more time the more properties need to be examined; and a fourth group, which takes more time than the others, appears to take into account what they would have proposed had they been put in the role of the proposer. We discuss implications of this joint decision–response time analysis. Copyright © 2013 John Wiley & Sons, Ltd.     

Equilibrium Selection,Similarity Judgments,and the “Nothing to Gain/Nothing to Lose” Effect

Rubinstein and Leland have both demonstrated that many observed violations of expected and discounted utility can be explained if people employ similarity judgments to make choices. In this paper, I show that this decision process also explains which equilibria will be selected in single‐shot games with multiple equilibria and implies that play in games will be associated with anomalies in risky choice. Data supporting these predictions are presented. Copyright © 2012 John Wiley & Sons, Ltd.     

Effects of 7.5% CO2-Induced Anxiety on Individual Performance During a Group Computer Combat Game

The inhalation of 7.5% CO₂ has been shown to induce cognitive effects similar to anxiety. Sixteen healthy participants (14 male; mean age 25.6 years) inhaled either a mixture of 7.5% CO₂ gas or air while playing a group combat computer game. Participants reported greater feelings of anxiety and fired fewer bullets when inhaling CO₂ compared with air, indicating CO₂-induced anxiety may improve efficiency without task-related decrements. Being able to induce controlled and measured anxiety in group situations by CO₂ inhalation may be a useful technique when evaluating response to stressful situations, such as combat, in simulators or real-life scenarios.     

Book reviews

Current research on medically unexplained somatic symptoms (MUSS) shows a renewed interest in psychodynamic approaches. Patients with MUSS lack the capacity to mentalize about their feelings. They have an attachment history characterized by insecure attachment relationships. They have a personality trait that can be best described as self-critical perfectionism. Their insecure early attachment relations have had a negative impact on the development of their stress regulatory system. Staff of Psychotherapeutisch Dagcentrum, affiliated with the Department of Psychiatry of a general hospital in Tilburg, found dynamic interpersonal therapy (DIT) a suitable treatment model for the treatment program that was run for patients with MUSS. DIT was developed by Lemma, Fonagy, and Target in the UK for the individual treatment of patients suffering from depression. Subsequently, a variant of DIT was developed in order to make it suitable for application in a multidisciplinary group setting.     

Receiving slaps,receiving words. The violence of separation in a public service time limited psychotherapy group for adolescents

The authors propose a reflection on a time-limited psychoanalytic group for children, adolescents and families, run in a public service. Some patients in the group give accounts of violent relationships and traumatic experiences. The accounts of violent, interpersonal and intrapsychic relationships influence the group’s capacity of thinking, which leads to difficulties in the processing of symbolic aspects. The fundamental question is that of whether it is possible to work in a time-limited, institutional, psychoanalytical framework, in which psychotherapists have to attempt to give meaning to experiences which take place in a repetitive present, in a space/time in which the prospect of a conclusion appears to be inconceivable. By means of a clinical example, and with particular emphasis on the first sessions and the dream brought up by a patient who has been a victim of domestic violence, the authors discuss the possibility of modifying, chiefly from within, the feeling of the immutability of early psychic material, which is itself intrinsically violent.
