异性交友决策任务上为不同心理距离他人决策的风险偏好

使用中国文化背景下修订的Beisswanger等人的异性交友决策问卷, 采用2种方法操纵自我-他人心理距离, 考察了男女大学生在后果严重性不同的异性交友决策任务上为不同心理距离他人决策风险偏好的差异。实验1发现, 被试为具体和笼统他人决策时的风险偏好无显著差异, 在后果不严重任务上比后果严重任务上更冒险, 男性比女性更冒险。心理距离与决策者性别的交互作用显著：男性为具体他人决策更冒险, 而女性为笼统他人决策更冒险。实验2发现, 被试为不相似他人比为相似他人决策更冒险, 在后果不严重任务上比在后果严重任务上更冒险, 男性比女性更冒险。后果严重性与决策者性别交互作用显著：男性在后果严重和不严重任务上的风险偏好无显著差异, 而女性在后果不严重任务上比后果严重任务上更冒险。综合两个实验的结果, 可以得出以下结论：相对于具体和笼统他人的区分而言, 相似和不相似他人的区分是一种更加稳定和有效的区分自我-他人心理距离的方法。结合相关研究及理论对结果进行了讨论。     

正面自我标签对建议采纳的影响

研究设想给决策者“贴标签”会影响其建议采纳, 即当决策者受到某一词语或文字(标签)的描述, 其往往向标签所预示的方向发展。通过三个依次递进的研究, 探讨在有无获益希望及公开与否三种不同组合的决策场景中, 启动决策者正面自我标签对其建议采纳的影响。实验1采用2(正面自我标签：启动/未启动)×2(获益希望：有/无)组间设计, 实验2和实验3分别进一步研究无获益希望的公开场景和有希望获益的不公开场景, 分别以91、135和96名在校大学生为被试。结果发现：决策者正面自我标签启动使得其更容易采纳建议; 无获益希望公开条件下, 受印象管理或社会赞许性影响而显著提高建议采纳; 有获益希望的公开条件下, 决策者正面自我标签启动使得其积极情绪得到提升, 并进而促进其采纳建议, 而积极意义发现在积极情绪和建议采纳之间起中介作用。     

条件性的关联学习和消退过程的性别差异

采用事件相关电位技术和条件性关联学习模型相结合的方法, 考察在负性背景下男女性对一般事件的关联学习和消退是否存在差异。结果表明：在关联学习阶段, 男性较女性表现出P2潜伏期缩短和N2波幅增大, 而女性比男性表现出更大的P3波幅。在消退阶段, 女性较男性出现更小的P2波幅和更大的P3/LPP波幅。这说明女性可能慢于男性探索到条件刺激和非条件刺激之间的关联, 并且保持时间更久; 男性在相对早期对消退产生更大的反应, 女性则在相对晚期对消退投入更多的资源及努力。     

面孔知觉中面孔性别与情绪表情的相互作用

面孔知觉中, 面孔性别与表情的加工有不同的机制。Bruce和Young (1986)及Haxby, Hoffman和Gobbini (2000)的面孔知觉理论虽然对表情加工也较为关注, 但对面孔性别加工机制的解释却较少, 也未能明确面孔性别与表情的相互关系。当前关于两者是否独立加工尚无明确结论, 但更多证据支持它们相互影响。我们认为, Garner范式下面孔性别与表情加工的研究可能忽略了面孔熟悉性因素。同时, 面孔适应范式为该研究领域提供了新的思路。此外, 文章对于两者相互作用的机制也进行了一定的探讨。     

A Pandemic of Terror and Terror of a Pandemic: American Cultural Responses to HIV/AIDS and Bioterrorism

Abstract. The cultural construction of American societal responses to the HIV/AIDS pandemic and terrorism is addressed. The use of metaphors of war, survival, extinction, and of those related to God in public narratives is analyzed. Issues of gender, sexuality, money, and power are also discussed within the context of the religion‐science dialogue. Suggestions are made about a possibility for a global ethic of survival based on an ethic of care.     

You still feel different: the experience and meaning of women's self‐injury in the context of a lesbian or bisexual identity

This article reports an intensive qualitative study of the subjective experience and meaning of self‐injury for 16 women who identified as lesbian or bisexual and who had deliberately self‐injured on repeated occasions. In individual interviews, the women talked about their experiences of self‐injury and the role it played in their lives as lesbian or bisexual women. Interpretative Phenomenological Analysis (IPA) was used to elicit themes arising within their accounts. These highlighted a number of ways in which social and contextual factors contributed to the development of self‐injury. Although many of these factors seemed applicable to any woman who self‐injures, there were some aspects that were specific to the experience of lesbian and bisexual women. In addition, the women's accounts raised a number of important issues about the way in which mental health services respond to lesbian and bisexual women who self‐injure. It is argued that self‐injury can be understood as a coping response that arises within a social context characterized by abuse, invalidation, and the experience of being regarded as different or in some way unacceptable. These factors are especially salient in the lives of women, and they emerge particularly strongly as part of the experience of women who are developing a lesbian or bisexual identity.

Perceived Group Status Differences and the Effects of Gender, Ethnicity, and Religion on Social Dominance Orientation

Social dominance orientation (SDO) is a measure of general desire for group-based dominance. According to social dominance theory, the higher the status of one's group, the higher one's level of SDO should be. This study examined the extent to which between-group differences in SDO increase as the size of the perceived status gap between the groups increases. Data were collected in Israel, Northern Ireland, and the United States. In agreement with expectations, differences in SDO between arbitrary-set groups (e.g., ethnic and religious groups) were found to be greater when the status gap between the groups was perceived to be larger. In contrast, gender differences in SDO did not vary as a function of the size of the perceived status gap between men and women: Men had higher levels of SDO than women even when the gender status gap was perceived to be very small. These findings highlight the effects of perceived group status on SDO and the degree to which these effects vary depending on whether the salient group distinction is based on gender, ethnicity, or religion.     

Sex differences in social representations of aggression: Men justify,women excuse?

Women tend to hold an expressive social representation of aggression (as a loss of self‐control) while men tend to hold an instrumental representation (as a means of imposing control over others). Because expressive beliefs correspond to excuses and instrumental beliefs to justifications, it may be a sex difference in moral acceptability of aggression that informs social representation. Participants completed the Expagg questionnaire with reference to an episode of same‐sex or cross‐sex physical aggression and rated the moral acceptability of their behaviour. Women scored higher on Expagg (specifically lower than men on the instrumental scale) but there was no effect of target sex or participant‐by‐target interaction. Contrary to expectation, women rated their own aggression as more acceptable than did men and hence this could not explain their lower levels of instrumentality relative to men. Aggr.
