Maternal perinatal representations and their associations with mother–infant interaction and attachment: A longitudinal comparison of Portuguese and Brazilian dyads

Prior research in Western countries (mostly the US, Canada and northern Europe) indicates that mothers' representations are associated with mother–infant interaction quality and their child's attachment security later in the first year. Fewer studies, however, have evaluated whether these associations hold for mother–infant dyads in other countries, such as Brazil and Portugal. Although these countries share a similar language and culture, they differ on societal dimensions that may affect parenting attitudes and mother–infant relationships, such as economic stress, social organisation, social policy, and the availability of services for young families. In this longitudinal study, we followed two independent samples of Brazilian and Portuguese mother–infant dyads from the perinatal period to 12 months post-partum. We assessed mothers' perinatal representations using semi-structured interviews in the first 48 hours after the infant's birth, and evaluated the associations of these representations with mother interaction quality at 9 months and infant attachment at 12 months. Results were similar in each country, corroborating prior research in single Western countries: Mothers with more positive perinatal representations were more sensitive to their infants during free play at 9 months and were more likely to have infants classified as securely attached at 12 months.     

睾酮与人类攻击行为

睾酮是一种可以在男性的睾丸间质细胞、女性卵巢和胎盘的皮层细胞中合成并分泌的雄性激素, 它可以调节个体的各种生理、形态和行为过程, 对个体生存和繁殖至关重要。大量研究表明, 睾酮与社会行为的关联存在双向性, 睾酮可以调节社会行为, 社会行为可以反馈并进一步影响睾酮水平。我们将关注点聚焦于睾酮与人类攻击行为之间的关联。早期研究发现, 高睾酮水平个体表现出更高的攻击性; 近期的研究根据挑战假设理论模型和生物社会地位模型得出, 人体内的睾酮水平对竞争性相互作用具有高度反应性。此外, 通过对大量研究的回顾与分析, 我们总结出睾酮水平的变化可以通过增强杏仁核的反应性或减少前额叶皮质-杏仁核功能耦合来影响攻击行为。未来的研究者应考虑其他激素(如皮质醇)和人格特征调节睾酮和人类攻击行为之间关系的潜在作用, 以及相关的生物学机制。     

计算模型在道德认知研究中的应用

道德认知关注道德心理背后的信息加工。近年来, 研究者开始将计算模型应用于道德认知研究, 以探索道德认知如何在大脑中实现。但目前研究者对道德认知进行计算建模的研究处于起步阶段。计算模型(漂移扩散模型、效用模型、强化学习模型和分层高斯过筛器模型)在道德认知行为和生理研究上的运用量化了道德决策、道德判断和道德推理背后的认知过程和神经机制。此外, 这一新进展对理解反社会行为和精神障碍等有所助益。最后, 计算建模有待完善, 未来研究需要关注其潜在的问题。     

Cognitive behaviour therapy to treating bulimia nervosa: A case study

The general cognitive behaviour therapy postulates that bulimic symptoms are maintained by a characteristic set of overvalued thoughts about the personal implications of body shape and weight. Research shows that there is both a close relationship and specific interaction between thoughts and behaviours that help to maintain the overvalued thoughts. This theoretical proposition concerning the role of behaviours in the maintenance of psychological problems is commonly accepted and empirically validated. To ensure a sustainable therapeutic change in the treatment of bulimia nervosa, therapists may need to initially target these overvalued thoughts about the personal implications of body shape and weight; and then to work on the behaviours that help to maintain the bulimic symptoms. The purpose of the present paper is to discuss the conceptual and practical issues underpinning a therapeutic focus that reflects an integrated clinical approach in the treatment of bulimia nervosa. This integrated approach includes the assessment and disputation of the overvalued thoughts that are causal to bulimia nervosa, and various strategies that facilitate the change in those behaviours that help to maintain the bulimic conditions. Using a case example, this paper also discusses the cognitive behaviour conceptualization in the maintenance of bulimia nervosa.     

Retributive justice and social categorizations: the perceived fairness of punishment depends on intergroup status

In the current research, the authors investigate the influence of intergroup status and social categorizations on retributive justice judgments, that is, the extent to which observers perceive punishment as fair. Building on social identity theory and the model of subjective group dynamics, it is predicted that when the ingroup has higher status than the outgroup, people are relatively less concerned about punishment of an outgroup offender than when the ingroup has lower status than the outgroup. Two experiments revealed that participants are more punitive towards an ingroup than an outgroup offender when ingroup status is high but not when ingroup status is low. Furthermore, in correspondence with our line of reasoning, this finding emerged because participants were less punitive towards outgroup offenders when ingroup status is high than when ingroup status was low. It is concluded that the perceived fairness of punishment depends on the offender's social categorization and intergroup status. Copyright © 2007 John Wiley & Sons, Ltd.     

农村重点高中学生学校人际关系状况的调查研究

采用《中学生师生关系测验问卷》和《中学生同学关系测验问卷》对随机选取的1120名苏北农村省级重点高中生进行测试。结果发现：绝大多数高中生的师生关系、同学关系是良好的和一般的,师生关系较差的只有6%左右,同学关系较差的却有20%左右;师生关系和同学关系都存在着显著的年级差异和性别差异。     

What do we learn from the Implicit Association Test about intergroup attitudes in Hong Kong? The case of social identification inclusiveness and need for closure

The current study tests an implication of the Associative-Propositional Evaluation model of implicit and explicit attitude measures in Hong Kong's intergroup context. We argued that the Implicit Association Test taps associative intergroup evaluations that are not necessarily consistent with the propositional implications of one's social identification inclusiveness and need for closure. In contrast, explicit intergroup attitude measures tap propositional evaluations resulting from validating the inferences drawn from pertinent propositional information in the evaluation context. Thus, explicit intergroup attitude should be consistent with the propositional implications of social identification inclusiveness and need for closure. We tested and found support for these hypotheses in a study of Hong Kong adolescents' ( N  = 65) perception of Hong Kong people and Mainland Chinese.     

决策与推理的双系统——启发式系统和分析系统

近来,在决策与推理的研究中,研究者提出了双系统作用模型：基于直觉的启发式系统和基于理性的分析系统。启发式系统加工速度较快,不占用或占用很少的心理资源,容易受背景相似性、刻板印象的影响;分析系统加工速度慢,占用较多的心理资源,遵从逻辑和规则,而且两个系统有不同进化历史和神经基础。该文根据已有的相关研究,综述了双系统在决策与推理中可能的作用机制、相互关系、个体差异,同时指出了目前研究存在的不足     

攀缘激活的计时机制

攀缘激活指神经元在两个先后出现事件的间隔阶段呈现出的一种缓慢爬升式“期待”激活。这种激活的强度在后一事件出现时达最高峰,以致被视为一种可能时距编码机制而成为目前时间生物学研究的一个热点问题。目前攀援激活的计时作用神经机制有三种主要观点：膜电流假说、双稳态单元假说、线性整合假说。未来研究将主要集中于探索攀缘激活的神经元突触机制,非固定间隔时距条件下攀缘激活的计时机制及攀缘激活、运动准备和脉冲累加之间的关系。
