安全依恋启动效应的内在机制：非安全依恋风格调节下情绪与认知的协同作用

安全依恋启动具有一系列积极心理效应,且表现出启动效应普遍性与特异性的共存。两种属性的区别在于个体非安全依恋风格是否参与调节,这一调节与个体的依恋策略使用和概念联结程度紧密相关。当前,对于安全依恋启动内在机制的探讨集中在情绪缓冲与认知调控过程,本文回顾现有关于安全依恋启动的主要结论与解释,整合安全依恋启动的神经基础,并纳入依恋风格的调节因素,提出一个安全依恋启动的情绪/认知协同作用模型。最后围绕需要深入探讨的关键问题进行了展望。     

哲学的反思与超验

哲学作为“思想的思想”之认识论定位,表明它具有强烈的反思性,亦构成了它的超验性。哲学反思与超验思想的特质,由哲学之认识对象及其与对象的本质关系所规定,亦由哲学之穷是究理的至上性思维使命与中介性递进过程所规定。它们是哲学之谓的重要思想理据。     

Defense Mechanism Test (DMT) and Kernberg's theory of personality organization related to adolescents in psychiatric care

75 adolescent psychiatric patients were diagnosed with the perceptual projective test the Defense Mechanism Test (DMT) and also according to Kernberg's theory of personality organization (PO). The test protocols were scored in respect of 130DMT variables and analyzed by means of partial least squares (PLS) discriminant analysis. The objective was to try to separate the three types of PO, psychotic (PPO), borderline (BPO) and neurotic (NPO) by means of the DMT and also to compare the results with a similar study on adult psychiatric patients. The results showed that it is possible to separate significantly the three groups of PO. The BPO group seemed to be heterogeneous. The results were fairly similar to those obtained with adult psychiatric patients. The overall results supported the concurrent validity of Kernberg's theory of PO and for the DMT as well. The DMT seems to be a useful diagnostic method in respect of adolescent psychiatric patients.     

The logic of how-questions

Philosophers and scientists are concerned with the why and the how of things. Questions like the following are so much grist for the philosopher’s and scientist’s mill: How can we be free and yet live in a deterministic universe?, How do neural processes give rise to conscious experience?, Why does conscious experience accompany certain physiological events at all?, How is a three-dimensional perception of depth generated by a pair of two-dimensional retinal images?. Since Belnap and Steel’s pioneering work on the logic of questions, Van Fraassen has managed to apply their approach in constructing an account of the logic of why-questions. Comparatively little, by contrast, has been written on the logic of how-questions despite the apparent centrality of questions such as How is it possible for us to be both free and determined? to philosophical enterprise.¹ In what follows I develop a logic for how-questions of various sorts including how-questions of cognitive resolution, how-questions of manner, how-questions of method, of means, and of mechanism.     

排除“每个人都优于平均水平”机制影响的自我提升研究

采用优于平均效应、自我服务归因偏向和内隐测验三种方法测量中国大学生的自我提升,并在前两种方法中考虑了EBTA机制的影响,以探讨中国人的自我提升动机及其表现形式。结果发现：EBTA机制影响显著;排除EBTA机制的影响后,大学生依然存在优于平均效应和自我服务归因偏向;大学生存在内隐自我提升值;内隐自我提升值与外显自我提升值之间存在显著正相关。     

Dialectical behavior therapy skills use as a mediator and outcome of treatment for borderline personality disorder

A central component of Dialectical Behavior Therapy (DBT) is the teaching of specific behavioral skills with the aim of helping individuals with Borderline Personality Disorder (BPD) replace maladaptive behaviors with skillful behavior. Although existing evidence indirectly supports this proposed mechanism of action, no study to date has directly tested it. Therefore, we examined the skills use of 108 women with BPD participating in one of three randomized control trials throughout one year of treatment and four months of follow-up. Using a hierarchical linear modeling approach we found that although all participants reported using some DBT skills before treatment started, participants treated with DBT reported using three times more skills at the end of treatment than participants treated with a control treatment. Significant mediation effects also indicated that DBT skills use fully mediated the decrease in suicide attempts and depression and the increase in control of anger over time. DBT skills use also partially mediated the decrease of nonsuicidal self-injury over time. Anger suppression and expression were not mediated. This study is the first to clearly support the skills deficit model for BPD by indicating that increasing skills use is a mechanism of change for suicidal behavior, depression, and anger control.     

Expanding the discussion: Revision of the fundamental assumptions framing the study of the neural correlates of consciousness

The way one asks a question is shaped by a-priori assumptions and constrains the range of possible answers. We identify and test the assumptions underlying contemporary debates, models, and methodology in the study of the neural correlates of consciousness, which was framed by Crick and Koch’s seminal paper (1990). These premises create a sequential and passive conception of conscious perception: it is considered the product of resolved information processing by unconscious mechanisms, produced by a singular event in time and place representing the moment of entry. The conscious percept produced is then automatically retained to be utilized by post-conscious mechanisms. Major debates in the field, such as concern the moment of entry, the all-or-none vs graded nature, and report vs no-report paradigms, are driven by the consensus on these assumptions. We show how removing these assumptions can resolve some of the debates and challenges and prompt additional questions. The potential non-sequential nature of perception suggests new ways of thinking about consciousness as a dynamic and dispersed process, and in turn about the relationship between conscious and unconscious perception. Moreover, it allows us to present a parsimonious account for conscious perception while addressing more aspects of the phenomenon.     

化学致癌机制的系统科学方法思考
