儿童的人际运动同步

人际运动同步是一种“社会胶粘剂”,能促进儿童产生更多的亲社会行为。儿童的人际运动同步能力随着年龄的增长不断提升,其同步表现受到运动方式、节奏刺激类型、同步对象等因素影响。在人际运动同步过程中,时间感知、运动计划和运动执行三大认知因素参与其中,既制约着个体同步能力的发展,也影响个体同步的表现。孤独症作为一种神经发育性障碍,孤独症儿童表现出异常的人际运动同步。未来的研究不仅要探讨孤独症儿童人际运动同步的异常机制,还要更多关注人际运动同步训练在孤独症群体中的实际应用和干预效果。     

Trajectory of change in anxiety sensitivity in relation to anxiety,depression, and quality of life among persons living with HIV/AIDS following transdiagnostic cognitive-behavioral therapy

ABSTRACT

Persons living with HIV/AIDS (PLHIV) disproportionately suffer from anxiety and depressive symptoms and disorders. Although past work has examined the efficacy of cognitive-behavioral therapy (CBT) for depression, and to a lesser extent anxiety, among PLHIV, little is known regarding potential mechanisms underlying improvement in anxiety/depression among this group. Anxiety sensitivity is a well-established risk/maintenance factor for anxiety and depressive disorders and is hypothesized to play an important role in maintaining anxiety among PLHIV. Past work has identified anxiety sensitivity as a mechanism of action underlying changes in various anxiety domains yet it is unknown whether changes in anxiety sensitivity relate to changes in anxiety symptoms among PLHIV undergoing transdiagnostic CBT for anxiety. The current study sought to examine treatment-related changes in anxiety sensitivity and how the trajectory of change relates to anxiety and depressive symptoms as well as overall quality of life. Individuals (n = 35) with HIV/AIDS and elevated anxiety symptoms received CBT for anxiety. Results indicated that reductions in anxiety sensitivity were significantly related to changes in anxiety, depression, and quality of life. Together, these data suggest that changes in anxiety sensitivity are significantly related to changes in anxiety/depression and quality of life among PLHIV seeking treatment.     

Do smokers devaluate smoking cues after go/no-go training?

Objective: Smoking is one of the leading public health problems worldwide. The inability to quit smoking may be the result of the amplified value of smoking-related cues and inhibitory control deficits. Previous research has shown that pairing substance-related cues with no-go trials in go/no-go training reduces the value of these cues, an effect known as devaluation. The current experiment investigated the devaluation effect of go/no-go training on smoking-related cues, and compared this effect between smokers and nonsmokers.

Design and Main Outcome Measures: 39 smokers and 43 nonsmokers were trained to respond immediately to neutral stimuli, but inhibit their reaction when smoking stimuli were presented. Before and after training, participants evaluated smoking and neutral stimuli, where part of these stimuli were subsequently presented in the training, and the other part was not used in training.

Results: Not responding to smoking stimuli in go/no-go training decreased subsequent evaluations of trained smoking stimuli compared to untrained smoking stimuli, thereby replicating food and alcohol studies and extending the devaluation effect to smoking-related cues. This devaluation effect was found for both smokers and non-smokers.

Conclusion: Smoking-related cues can be devaluated in smokers and non-smokers, thereby showing the potential for Go/No-Go training in smoking cessation interventions.     

The development of our sense of self as a defense against invading thoughts: From Buddhist psychology to psychoanalysis

In interdisciplinary debates on the nature of the self, no-self accounts often refer to Buddhist psychology, arguing that the self is an illusion arising from our identification with mental content. What is often missing, however, is a developmentally, motivationally and emotionally plausible reason why this identification happens in the first place. It is argued that directing attention to our ongoing thought activities and their effect on our mind reveals their often invasive character. This is supported by psychoanalytic accounts on the ontogenetic and phylogenetic origins of thinking. On an experiential level, invading thoughts have similarities to attacks and provoke defensive reactions. The defense mechanism described as identification with the aggressor is used as a model in order to better grasp how we deal with invading thoughts, namely, by identifying with them and thus generating a sense of self as an agent of thoughts which provides an illusion of control.
