抑郁的多基因遗传基础

抑郁具有复杂的、非孟德尔式的多基因遗传模式, 但是目前多数抑郁的遗传研究集中于考察单个候选基因, 不能全面揭示遗传因素的作用机制。近年来, 多基因遗传得分研究和基因−基因交互研究分别为抑郁的多基因累加效应和交互效应提供了新的证据。多基因不仅直接影响抑郁, 还通过与环境因素的交互作用影响抑郁的发生发展, 并且这一复杂交互作用存在性别差异。抑郁的内表型研究发现多基因可能通过认知因素、人格、压力荷尔蒙等间接影响个体的抑郁水平。未来研究应更加关注多基因与多种环境因素如何相互作用影响抑郁, 探索多基因遗传机制的性别差异, 考察多基因对抑郁影响随年龄的发展动态变化。     

儿童类别学习中知识效应的年龄差异

采用特征主题的类别学习实验范式,考察了儿童类别学习中知识效应的年龄差异。63名小学4年级学生(年龄范围9～10岁)、65名小学6年级学生(年龄范围11～12岁)和77名初中2年级学生(年龄范围13～14岁)参加了本实验。结果表明:当类别特征能够在已有知识的基础上形成主题时,3个年龄组儿童类别学习的轮次和错误数均显著下降,而且主题突出时,这种趋势更加明显;在统一主题条件下,小学4年级、小学6年级和初中2年级3个年龄组儿童类别学习的轮次和错误数依次减少;而在无主题和突出主题条件下,3个年龄组儿童类别学习的成绩无显著差异。     

Measured and self-estimated trait emotional intelligence in a UK sample of managers

Trait emotional intelligence (EI) was measured and self-estimated in a UK sample of 128 managers (52.3% female), recruited at a professional services firm. Participants’ measured scores were compared to standardization sample data and gender differences in measured and estimated scores, as well as in estimation bias and accuracy were examined. As hypothesized, managers’ global trait EI scores were significantly higher than those of the normative sample of the measure used, although the scores of female participants were largely responsible for this difference. Gender-specific hypotheses were confirmed for measured scores (differences only hypothesized at the factor level) and estimation accuracy (males estimating their trait EI more accurately), but not for estimated scores (female participants had higher estimates, but the opposite was hypothesized). Further, female managers showed signs of estimation bias.     

Why is support for Jamesian actual–ideal discrepancy model so elusive? A latent-variable approach

We investigate the Actual–Ideal Discrepancy (AID) model of self-esteem determination dating back to James (1890/1963). Although intuitively appealing, this model received weak support from rigorous empirical research. We propose a multiple-item latent difference approach to AID as applied to a range of self-concept domains and sub-domains in young adolescents from two different countries (UK: N = 402; Italy: N = 250). The effects of the AID remained elusive for most domains and sub-domains; indeed, the effects of the specific AIDs were generally trivial and only appearance-AID became significant in the combined sample. Also AIDs did not substantially explain the more general self-concepts beyond what was explained by the actual domains. Even if they had been significant, AID effects would have been, at best, trivially small and detectable only using appropriate latent-variable methodologies coupled with large sample sizes; thus undermining the psychological meaning of the AID model.     

社会距离和性别对公平关注的影响

本研究使用单次匿名最后通牒博弈任务,采用2（性别: 男性, 女性）×3（社会距离: 自我决策, 替朋友决策, 替他人决策）×5（提议类型: 1/9, 2/8, 3/7, 4/6, 5/5）的混合实验设计,通过操作反应者的不同社会距离,考察资产分配情境下自我-他人决策的性别差异。研究结果发现：（1）相比于自我决策和替朋友决策,女性被试替他人决策时更愿意接受提议1/9,2/8和3/7,而提议4/6和5/5的接受率不受社会距离的影响;男性被试中社会距离和提议类型的交互作用不显著;（2）不平等提议的反应时随社会距离增加而逐渐降低,而平等提议的反应时不受社会距离的调节;（3）替他人决策时女性的接受阈限显著低于男性,而自我决策及替朋友决策时接受阈限不存在性别差异。     

Equal prioritisation does not yield lower levels of participation in physical activities than higher prioritisation

ObjectivesThis study examined whether individuals who assigned equal priority to physical activity and an alternative activity exhibited lower levels of participation in physical activities than individuals who assigned higher priority to physical activity than an alternative activity. In addition, we examined whether a measure of prioritisation derived from an algebraic difference index provided a rigorous test of prioritisation effects.DesignWe employed a two-wave prospective design that aimed to predict physical activity participation.MethodPrioritisation, intentions and perceptions of control were measured at the first wave of data collection. After five weeks, we administered follow-up measures of behavioural conflict and physical activity participation.ResultsA hierarchical regression analysis showed that although the algebraic difference index was positively associated with measures of physical activity participation, equal prioritisation did not yield lower levels of physical activity participation than high prioritisation.ConclusionsFindings suggest that equal prioritisation is not a less optimal self-regulatory strategy than high prioritisation in the domain of physical activity. Regression coefficients associated with algebraic difference indexes should be interpreted with caution and consider analyses that examine effects of component measures of prioritisation on physical activity participation.     

Marital Processes Linking Gender Role Attitudes and Marital Satisfaction Among Mexican‐Origin Couples: Application of an Actor–Partner Interdependence Mediation Model

Informed by dyadic approaches and culturally informed, ecological perspectives of marriage, we applied an actor–partner interdependence mediation model (APIMeM) in a sample of 120 Mexican‐origin couples to examine (a) the associations linking Mexican immigrant husbands’ and wives’ gender role attitudes to marital satisfaction directly and indirectly through marital processes (i.e., warmth and negativity) and (b) whether the associations between spouses’ gender role attitudes and marital processes were moderated by wives’ employment. Although previous research has identified spouses’ gender role attitudes as potential predictors of spouses’ marital satisfaction, no study has examined these links in a dyadic model that elucidates how gender role attitudes may operate through processes to shape marital satisfaction and conditions under which associations may differ. We found that when spouses reported less sex‐typed attitudes, their partners reported feeling more connected to them and more satisfied with the marriage, regardless of whether wives were employed. Our results suggest that marital satisfaction was highest for those Mexican‐origin couples in which marital partners were less sex‐typed in their attitudes about marital roles to the extent that partners’ attitudinal role flexibility promoted spouses’ feelings of warmth and connection to their partner.     

Sex differences in personality are larger in gender equal countries: Replicating and extending a surprising finding

Sex differences in personality have been shown to be larger in more gender equal countries. We advance this research by using an extensive personality measure, the IPIP‐NEO‐120, with large country samples (N > 1000), from 22 countries. Furthermore, to capture the multidimensionality of personality we measure sex differences with a multivariate effect size (Mahalanobis distance D). Results indicate that past research, using univariate measures of effect size, have underestimated the size of between‐country sex differences in personality. Confirming past research, there was a strong correlation (r = .69) between a country's sex differences in personality and their Gender Equality Index. Additional analyses showed that women typically score higher than men on all five trait factors (Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness), and that these relative differences are larger in more gender equal countries. We speculate that as gender equality increases both men and women gravitate towards their traditional gender roles.     

French Validation of the Competitive Aggressiveness and Anger Scale (FVCAAS)

The aim of this study was to propose a French Validation of the Competitive Aggressiveness and Anger Scale (FVCAAS). The instrument was developed from the original version, which is composed of two subscales (six items by subscales) assessing aggressiveness and anger in competitive athletes (CAAS, Maxwell & Moores, 2007). Four studies have been conducted with 1428 competitors. In the first study, the exploratory factor analysis extracted the two-factor structure from the original version, both with good internal consistency. The second study confirmed that the two-factor structure of the instrument was consistent with the original version and showed its partial invariance across genders. The third study demonstrated the temporal stability of the FVCAAS. In the fourth study, both concurrent and discriminant validities were confirmed, supporting the validity and reliability of the FVCAAS. The contributions of this study and limitations are discussed, together with perspectives for future studies of aggressiveness in competitive sports.     

Overcoming the “Holy Hush”: A Qualitative Examination of Protestant Christian Leaders’ Responses to Intimate Partner Violence

Described as a “holy hush,” past research has noted a general silence about and reluctance to address intimate partner violence (IPV) in religious congregations. To explore this, we interviewed 20 Protestant Christian religious leaders about how they understood and responded to IPV. Based on a thematic content analysis, our study revealed some of the challenges, tensions, and complexities that may be barriers to leaders speaking about and responding to IPV, and also the ways religious leaders in our sample attempted to overcome these challenges. For example, results revealed religious leaders understood violence on a gradation from less to more severe, and linked a need for and type of response to the level of violence. Throughout, religious leaders expressed a tension between their leadership role and responding to IPV. Furthermore, religious leaders acknowledged their need for greater training and connections to service providers, however, they reported not currently being connected to other IPV resources or organizations in the community. We discuss how the findings illuminate challenges and tensions for religious leaders in responding to IPV and how some leaders in this study were navigating these tensions to respond. We also discuss how findings may inform future research and the development of trainings and protocols for religious leaders and congregations on responding to IPV, promoting survivor safety, and fostering a greater understanding of IPV. Implications for collaboration with other community‐based IPV organizations are also discussed.
