性别角色和主观幸福感的关系模型：基于中国大学生的检验

在西方文化下,关于理想的性别角色类型主要存在三种观点：一致性模型、双性化模型、男性化模型。按照一致性模型,具有男性化特质的男性和具有女性化特质的女性是最为理想的;按照双性化模型,在男性化特质和女性化特质两个维度上得分都高的个体社会适应性最强而且心理最健康;按照男性化模型,男性化特质才是心理健康和社会适应的主要决定因素。研究运用大样本的网络数据,探讨在中国文化下,上述三个模型在中国的适用性,具体地,在性别角色类型和主观幸福感的关系上的适用性。结果发现：双性化模型得到支持,同时具有男性化特质和女性化特质的个体主观幸福感最高;男性化模型和一致性模型都没有得到支持。这表明在当代西方文化下的理想模型——男性化模型并不适用于中国,理想的性别角色模型具有文化特异性。这一结果不仅增进和丰富了人们对文化对心理和行为的影响的认识,还对我国目前青少年良好个性品质的塑造和培养以及心理健康教育的实践具有重要指导作用     

儿童2~7岁行为抑制性的发展

采用实验室录像观察对中国儿童的行为抑制性的发展进行了追踪研究(2岁、4岁、7岁)。儿童2岁时,有124名儿童参加了实验室观察。儿童4岁时,由于搬迁、退出或失约,有103名儿童参加。儿童7岁时由于以上原因有100名儿童参加实验室观察。在2岁、4岁、7岁至少参加一次观察的儿童有113名,而在三个时间点都参加观察的儿童有89名。我们对儿童2~7岁行为抑制性整体发展的稳定性以及行为抑制性和非抑制性的发展趋向进行了分析。结果表明,中国儿童从2岁到7岁的行为抑制性的整体发展稳定性较低。从2岁到7岁,行为抑制性-非抑制倾向比较稳定的儿童共28人,占总人数的31.5%。而行为抑制性-非抑制性不稳定的儿童为61人,占总人数的68.5%。随着年龄增长,本研究中的儿童的行为抑制性-非抑制性倾向有向中间型趋中的趋势。从2岁到7岁,行为抑制性的发展变化没有显著性别差异     

围生期双酚A暴露对不同性别子代小鼠行为的影响

探讨围生期母体双酚A(bisphenol A, BPA)暴露对幼年期(生后21~30天, postnatal day 21~30, PND 21~30)和青年期(生后56~63天, PND 56~63)不同性别子代小鼠行为的影响。母鼠从妊娠第7天至断乳前(产后21天)进行BPA(0.05、0.5、5、50 mg/kg/day)灌胃染毒, 同时设对照组。每个剂量组分别在PND 21和PND 56开始测试雌雄子代小鼠各项行为。以旷场行为检测小鼠的自发活动及探究行为, 以高架十字迷宫检测小鼠的焦虑行为, 以水迷宫检测小鼠的空间学习记忆能力, 以跳台检测小鼠的被动回避记忆行为。结果表明, BPA使PND 21雌雄子鼠和PND 56雄性子鼠自发活动减少(p<0.05或p<0.01), 理毛和站立行为发生性别分化(p<0.05或p<0.01); PND 21子鼠的3分钟跑动格数有明显的剂量效应关系, 其中5~50 mg/kg/day组特别显著。BPA显著增加PND 21雌雄子鼠和PND56雌性子鼠在高架十字迷宫中进入开放臂次数和停留时间(p<0.05或p<0.01)并减少封闭臂的进入时间, 但没有明显的剂量效应关系; BPA减少PND 56雄性子鼠开放臂的进入并增加其封闭臂的进入, 干扰了幼年期和青年期小鼠焦虑行为的性别分化。BPA剂量依赖性地延长PND 21和PND 56雄性子鼠在水迷宫搜索平台的平均距离, 其中5~50 mg/kg/day剂量组具有差异显著性(p<0.05或p<0.01), 但对雌性子鼠空间学习记忆行为没有影响。此外, 5~50 mg/kg/day BPA增加PND 21雄性子鼠在跳台实验中的错误次数并缩短其跳下平台潜伏期, PND 56雌雄子鼠的被动回避记忆仅被50 mg/kg/day BPA减弱。以上结果提示, 围生期BPA暴露可影响子代小鼠幼年期和青年期的多种行为及行为的性别差异, 不同行为对BPA的敏感程度不同, 其中以自发活动和探究行为最敏感。     

认知功能的性别差异

我们了概述认知功能的性别差异, 尤其是情节记忆功能的性别差异。已有的研究结果表明女性在言语生成、情节记忆、面孔识别任务中比男性存在明显的优势, 而男性的优势则表现在视空间任务中, 如视空间情节记忆任务。本文批判性地讨论了一个流行的假设: 类固醇激素影响认知功能的性别差异, 得出的结论是内源性睾丸激素或雌二醇均未显著影响认知功能的性别差异。     

Officer attitudes towards adult male prisoners who self-harm: development of an attitudinal measure and investigation of sex differences

Purpose: The aim of the current study was to explore attitudes towards self‐harm in a sample of prison officers, with subsidiary aims of assessing if these attitudes alter as a function of the prisoner's behavior and the sex of the participant. Method: One hundred and sixty‐two officers (100 men and 62 women) completed a general measure of their attitudes towards prisoners and one designed to assess Attitudes towards Prisoners who Self‐Harm (APSH). Participants rated their perceptions of two adult male prisoners depicted in vignettes. The vignettes depicted identical types of self‐harm but varied the behavioral characteristics of the prisoners involved, with one depicted as “well‐behaved” and the other as “disruptive”. Results: Women were more likely than men to report positive attitudes towards self‐harm and in particular were less likely than men to endorse negative myths regarding self‐harm. The prisoner depicted as “disruptive” invoked increased negative attitudes than the “well‐behaved” prisoner. This finding was consistent across sex. Conclusion: The current study indicates that APSH are comprised of a number of components that were influenced by the sex of the participant and the behavioral characteristics of the prisoners depicted. The implications of these findings to practice are discussed. Aggr. Behav. 33:63–72, 2007. © 2006 Wiley‐Liss, Inc.     

Physical aggression as a function of perceived fighting ability among male and female prisoners

Study 1 used two scenarios depicting provocations to investigate whether prisoners' willingness to engage in physical aggression would vary according to the perceived fighting ability (Resource Holding Power [RHP]) of the opponent. RHP was operationalized in terms of three levels of the size, number of allies, and reputation. The sample (both sexes; N=1,253) was taken from a range of British prisons. Unexpectedly, the prisoners said that they would be less likely to attack a weaker opponent than an equally matched one. The predicted decline from equally matched to more formidable opponents was found only under some conditions. A further sample of male prisoners (N=260), completed a similar provocation scenario, with response options covering fear, several forms of aggression, the importance of the provocation for reputation, and that the provocation was unimportant. Fear increased with RHP as predicted. Lower physical aggression to a low RHP opponent was again found, and it was associated with a lesser impact on reputation of an insult from this source. There was also a lower likelihood of responding with physical aggression to a high RHP opponent, as originally predicted. Implications of the findings for motivational theories of aggression are discussed, and also the applicability to humans of concepts from game theory models of the evolution of fighting strategies.     

Trustworthiness,friendships and self‐control: factors that contribute to young children's school adjustment

The aim of present study was to examine the relationship between young children's peer‐reported trustworthiness and their school adjustment. Two hundred and eleven (103 male and 108 female) children in the United Kingdom (mean age = 6 years 2 months) took part in this study. Measures of peer‐reported trustworthiness, child‐rated school adjustment, and teacher‐rated school adjustment were administered twice across a one‐year period. Also, children's number of friendships, peer acceptance, and self‐control were assessed at Time 2. Multisample path analyses were conducted separately by sex. For both samples there were direct longitudinal paths between peer‐reported trustworthiness and changes in teacher‐rated school adjustment. For boys, the longitudinal path between peer‐reported trustworthiness and changes in child‐rated loneliness was mediated by peer acceptance, and peer‐reported trustworthiness mediated the relationship between self‐control and teacher‐rated school adjustment. Sex differences in peer‐reported trustworthiness also emerged: girls were rated as more trustworthy by their peers than were boys. The findings support the hypothesis that young children's trustworthiness contributes to school adjustment, which is due in part to peer acceptance. Copyright © 2007 John Wiley & Sons, Ltd.     

Developmental and Sex Differences in Types of Conduct Problems

Maternal report of types of conduct problems in a high-risk sample of 228 boys and 80 girls (ages 4–18) were examined, using a version of the Child Behavior Checklist, expanded to include a range of covert and overt antisocial items (stealing, lying, physical aggression, relational aggression, substance use, and impulsivity). Age and sex effects were investigated. Boys were significantly more physically aggressive than girls. There were no sex differences for stealing, lying, relational aggression, and substance use. Lying and substance use increased with age, whereas relational aggression and impulsivity peaked during early adolescence. A small group of girls had pervasive conduct problems across multiple domains. For some domains such as stealing, lying, and relational aggression, girls showed at least as many problems as boys. Girls, in general, tended to have fewer conduct problems. On the other hand, when assessed across multiple domains, conduct problems in high-risk girls were possibly more pervasive than in high-risk boys, suggesting the possibility of a gender paradox.     

Psychosexual Dysfunction Among Gynecological Cancer Survivors

The purpose of this paper is to summarize the empirical findings related to the assessment and treatment of sexual difficulties commonly experienced by gynecological cancer survivors and to make suggestions for future research and practice in this area. First, we describe the sexual problems that are most frequently reported by gynecological cancer patients and some of their common medical and psychological correlates. These include pain, premature ovarian failure, changes in vaginal anatomy, emotional distress, body image, and sexual self-concept. The complex interaction of physiological and psychological variables plays an important role in the development of sexual dysfunction in this patient population. Furthermore, we review the empirical studies that have examined the effects of sexual rehabilitation therapy on the sexual functioning of gynecological cancer survivors and provide relevant research and clinical recommendations. We also discuss reasons to involve patients' sexual partners in psychosocial oncology research, given the complex interplay between patients' and partners' psychosexual issues.
