人际距离和情绪知觉对利他选择的影响

本研究采用社会正念范式（SoMi）,考察不同人际距离对其社会正念利他选择的影响。结果发现：（1）不同人际关系产生的人际距离对社会正念利他选择不同,被试与陌生人的利他选择最低,与父母的利他选择其次,与朋友的利他选择略高于对父母的利他选择;（2）情绪面孔产生的人际距离越近,利他选择行为越高,人际距离越远,利他选择行为越低;高兴面孔表情利他选择频次最高,悲伤面孔表情次之,愤怒面孔表情利他选择最低。     

Social Influences on Judgments of Rape Victims: The Role of the Negative and Positive Social Reactions of Others

An experimental study examined whether judgments about a rape victim can be influenced by the social reactions of others, and whether this effect would be moderated by the type of rape (stranger or date rape) or by the gender of the participants. One hundred and ten U.S. college students (90% white; 59% female) responded to rape vignettes in which the type of rape and the social reactions received by the victim (negative, positive, or neutral) were manipulated. People exposed to negative social reactions made less positive judgments. Men and people who read about a date rape also made less positive judgments, but neither variable interacted with type of reactions to impact judgments.     

The effects of confederate influence and confidence on the accuracy of crime judgements

Building on recent work which has investigated social influences on memory and remembering, the present experiment examined the effects of social pressure and confederate confidence on the accuracy and confidence of eyewitnesses. Sixty undergraduate participants watched a video of a staged mugging and then answered questions about the video out loud in the presence of either one or three confederates who had also watched the film with them. Unbeknownst to the participant, the confederate(s) always gave incorrect responses to four out of the eight questions. Participants and confederates were also asked to give confidence scores out loud for each of their answers. Again, unbeknownst to the participant, the confederate(s) always expressed either high or low confidence scores for the incorrect information, depending on condition. Participants gave fewer correct answers, and were less confident, in the presence of three, as opposed to one, confederates. Participants were also more confident, yet no more accurate, when the confederate(s) gave high, as opposed to low, confidence scores. Thus the presumed independence of evidence given by multiple witnesses cannot be safely assumed.     

Social identity, status characteristics and social networks: Predictors of advice seeking in a manufacturing facility

In the sociological tradition, status characteristics and patterns of interpersonal relations within a social network are considered important in explaining organizational behaviour (e.g. influence, cooperation). In the social identity tradition, perceptions of shared psychological group membership and group prototypicality are considered important in explaining many of the same organizational behaviours. The present paper explores core variables within each of these perspectives as predictors of advice seeking among supervisors in a manufacturing facility. Dyadic measures of group assignment are found to better predict advice seeking than measures taken at the individual level. Identification with work groups predicted advice seeking from those perceived to be in the same group, and also from structural equivalents. Implications for theory and further research are discussed.     

Testing for selectivity in the dependence of random variables on external factors

Random variables A and B, whose joint distribution depends on factors (x,y), are selectively influenced by x and y, respectively, if A and B can be represented as functions of, respectively, (x,S_A,C) and (y,S_B,C), where S_A,S_B,C are stochastically independent and do not depend on (x,y). Selective influence implies selective dependence of marginal distributions on the respective factors: thus no parameter of A may depend on y. But parameters characterizing stochastic interdependence of A and B, such as their mixed moments, are generally functions of both x and y. We derive two simple necessary conditions for selective dependence of (A,B) on (x,y), which can be used to conduct a potential infinity of selectiveness tests. One condition is that, for any factor values x,x^′ and y,y^′,

s_xy≤s_xy^′+s_x^′y^′+s_x^′y,     

社会网络视角下的同伴关系与心理健康

近年来, 从社会网络视角考察同伴关系与心理健康的相互作用正成为发展心理学和健康心理学研究的热点。研究者多借助整体网和纵向数据, 通过两种作用机制, 即选择过程(selection process) (强调心理和行为变量对社会网络和同伴关系的影响, 如关系的形成、维持和解除)和影响过程(influence process) (强调社会网络和同伴关系对心理和行为变量的影响), 来分析同伴关系与心理健康协同演进的动态过程。实证研究关注的领域集中在青少年健康风险行为(如吸烟、喝酒、药物滥用)和情绪问题(如抑郁、焦虑、孤独感)。未来研究应该注重拓展社会网络的类型和样本、加强理论建构、增加对积极心理和消极关系的研究, 并有望在互联网领域及社会网络的生物学基础等方面取得进展。     

微表情的特征、识别、训练和影响因素

微表情是人压抑的真实情绪的泄露, 时间约为1/25~1/2 s, 常出现在说谎情境, 可能源于椎体束运动系统控制的自主面部运动和椎体束外运动系统控制的非自主面部运动的“拔河比赛”。已有研究构建了微表情数据库, 开发了BART和JACBART等微表情识别测验以及METT训练, 并探讨了微表情识别及训练与认知、人格、文化、职业等的关系。但这些研究考察的中性表情背景下微表情只是镶嵌在各表情背景下真实微表情的特例, 生态程度不高; 少量研究探索了表情背景对微表情识别的影响但未建立标准测验。未来应开发生态化微表情识别标准测验和训练, 尝试跨越微表情发生和识别的界限, 并采用生理−心理、电生理和脑成像技术探索其机制。     

Behavioural coherence in violent group activity: An interpersonal model of sexually violent gang behaviour

This study provides an analysis of offender‐victim interactions in 223 cases of sexual violence committed in gangs. Cases were derived from archival sources such as law reports. A multivariate analysis revealed four interpersonal themes (dominance, submission, co‐operation, and hostility) previously identified in studies of lone sexual assault [Alison and Stein, Vicious Circles: Accounts of stranger sexual assault reflect abusive variants of conventional interactions. J Forensic Psychiatry 12:515–538, 2001]. These themes have also been identified in many other forms of human relating [Wiggins, An informal history of the interpersonal circumplex tradition. J Pers Assess 66:217–233, 1996] and conform to a structure known as the interpersonal circumplex. The circumplex has previously been used to conceptualise the relationships between individuals in terms of dynamic interactions that are mutually influencing. Thus, dominance elicits submission and submission elicits dominance. Each interpersonal style could be further subdivided according to the use of either verbally or physically abusive strategies. Point‐Biserial correlations with other aspects of the offence (e.g., mobility of the group, post‐offence treatment of the victim) provided additional support for these conceptually different themes and demonstrated that gang rape represents a distorted and violent form of interpersonal relating. Further, this dynamic interaction emerges not just at an individual level, but at a group level, suggesting that the thematic concepts underpinning the interpersonal circumplex can be extended to group activity and sexually aggressive behaviour.

A Spanish translation of Mehrabian and Russell's emotionality scales for environmental consumer psychology

The development of a translation of Mehrabian and Russell's scales for the measurement of pleasure, arousal and dominance from the original English to a Spanish version for use in Venezuela is described. The translated scales were administered to two samples of middle‐class Venezuelan consumers (n = 127,n = 127) between the ages of 20 and 50, among whom males and females were represented approximately equally. Internal reliability (measured by Cronbach's alpha) and scale validity (measured by factor analysis) indicate that the translated scales are suitable for consumer and other social psychological research in Spanish.
