基于网络理论的物质成瘾新视角

物质成瘾是一种涉及生理、心理和环境等多因素的复杂现象, 但是当前基于生物还原论的解释对物质成瘾现象整体性的理解和康复研究造成了阻碍。网络理论聚焦于心理障碍变量之间相互作用形成的反馈环路, 从整体视角为研究物质成瘾提供了新的理论框架。将网络理论应用于物质成瘾的研究中将有利于:(1)理解症状之间的相互关系和影响; (2)理解症状网络的整体性和系统性动态变化过程; 以及(3)将多层次和多水平因素整合到统一的理论框架中。从网络理论视角来理解物质成瘾, 也将对未来的干预和治疗提供了理论支持。目前, 网络理论仍处于言语模型阶段, 未来需要进一步提出更具体、可验证的统计模型, 以完善对于物质成瘾机制的了解, 更加有效地推进物质成瘾的治疗与恢复。     

自恋与行为抑制/激活系统的关系：元分析

运用元分析方法探讨自恋与行为抑制/激活系统的关系。经过文献检索和筛选, 纳入原始文献19篇, 包含25个独立样本, 共7702名被试。根据同质性检验结果, 选用随机效应模型。结果发现, 自恋与行为抑制系统存在中度负相关(r = -0.27, 95% CI为[-0.34, -0.21]), 自恋测量工具在两者间起显著的调节作用; 自恋与行为激活系统存在高度正相关(r = 0.46, 95% CI为[0.40, 0.52]), 被试类型在两者间起显著的调节作用。自恋与行为抑制/激活系统的密切关系支持了自恋的主体性理论和人格强化敏感性理论。     

非符号数量表征和符号分数表征的关系

个体学习符号分数的一个关键是能对其数值形成准确表征。现有研究假设符号分数表征的认知基础是人类自婴幼儿期就具有的非符号数量表征(如表征两个集合各自的数量, 或两个数量的比例)。其证据包括表征非符号数量(尤其是非符号数量比例关系)和表征符号分数在行为和大脑神经活动层面上都表现出相关性。然而要说明非符号数量表征是符号分数表征的认知基础, 还需更多研究表明两者在数量概念上的独特相关和因果联系, 并阐明符号分数表征形成的认知机制。     

Remembrance–Toward Righteousness and Reparations

This article explores “remembrance” as the first part of a planned three-part paper titled “Remembrance, Righteousness and Reparations,” intended as a conceptual framework and spirit guide of accompaniment for the World Council of Churches’ pilgrimage of healing, justice, and peace. This first part focuses on remembrance to counter the dis-membering, trauma, and woundedness inflicted by systems of acts of White supremacy, racism, patriarchy, and male privilege. Parts two and three of this paper offer righteousness and reparations as additional conceptual frameworks and spirit guides: righteousness to recentre and deepen our understanding of justice in a world fraught with human suffering, violence, and evil; and reparations to covenant and bind a process of truth-telling, reckoning, and reconciliation in the face of the consequences and legacies of the transatlantic slave trade system upon people of African descent.     

Regression II. Development through regression

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.     

Value and Obligation Once More

In Understanding Moral Obligation (2012), Robert Stern sets out to provide a fresh interpretation of the role of autonomy in Kant's moral philosophy and attempts to rectify J. B. Schneewind's standard account in The Invention of Autonomy (1998). While Stern agrees that Kant's resort to autonomy is at the basis of a constructivist account of moral obligation, he claims that autonomy plays no role in Kant's theory of value, such that, in this respect, Kant remains a realist. Accordingly, Stern characterizes Kant's moral philosophy as a “hybrid” view because he sees it as involving a compromise between realism with regard to value and constructivism with regard to obligation. Stern's interpretation relies on a sharp distinction between value and obligation. The purpose of the present article is to question Stern's reliance on that rigid distinction, which involves intermixing theoretical and practical reason and assumes a distorted view of human agency.     

Denial of gender discrimination is associated with better subjective well-being among women: A system justification account

Despite the fact that women face socially and politically sanctioned disadvantages every day, a large percentage of women and men report that gender discrimination is no longer a problem. Across three studies, which together include over 20,000 participants from 23 countries, we test the hypothesis that denial (vs. acknowledgement) of gender discrimination is associated with higher subjective well-being among women (Studies 1–3), and this is because denying gender discrimination promotes the view that the system is fair (Study 1). We further show that this happens above and beyond personal experiences with sexism (Study 1) and that the association is stronger in countries where sexism is relatively high (vs. low; Study 3). We argue that denial of discrimination is an individual-level coping mechanism and that, like other self-group distancing strategies, it may perpetuate gender inequality.     

An empirically derived scoring system for intermale aggression in mice

Scoring systems used to assess intermale aggression have been characterized by arbitrary scales and wide variability in the behaviors selected for measurement. The use of such different systems severely limits the ability of investigators to make meaningful comparisons among studies and indicates that there is a need for a common, statistically derived evaluative system for intermale aggression. We measured the frequency and duration of five major components of agonistic behavior exhibited by intact males toward olfactory bulbectomized stimulus males and then analyzed the data using a number of univariate and multivariate procedures. The results were used to generate two statistically based scoring systems, one a short-form index and the other a composite index for more detailed studies of aggression. It is hoped that these statistically derived systems will be adopted by other investigators to increase methodological congruence in the field.

Sticking to common values: Neighbourhood social cohesion moderates the effect of value congruence on life satisfaction

This article aims to explicate the role of social cohesion in the relationship between adherence to common values and life satisfaction. Shared values are often assumed to be a constitutive element of social cohesion and are used in measurement of the concept. However, sociopsychological theory of values sees social cohesion rather as a moderator of the link between value congruence and life satisfaction, not as a constituent of value congruence. Based on a representative survey of the city of Bremen, Germany (N = 2605), we predict life satisfaction from person‐group value congruence and neighbourhood social cohesion. We find no relationship between value congruence and social cohesion, but a significant positive moderating effect of social cohesion on the relationship between value congruence and life satisfaction. The findings suggest that sticking to common values does not increase social cohesion, but that positive effects of value congruence are more pronounced in high‐cohesion neighbourhoods.
