Task‐related interactions between kindergarten children and their teachers: the role of emotional security

This study examined the emotional security of kindergarten children in dyadic task‐related interactions with their teachers. In particular, it examined the interrelations between security, task behaviours (persistence and independence), social inhibition, and teachers' support. Participants were 79 kindergartners (mean age=69.7 months) and their 40 regular teachers. Children were selected to approach a normal distribution of social inhibition. Children and teachers were filmed during a dyadic interaction task outside the classroom. Three groups of independent observers rated children's emotional security and their task behaviours, as well as teachers' supportive behaviours. Multilevel modelling revealed a positive link between teachers' support and emotional security. This link suppressed a negative relation between social inhibition and emotional security. In addition, emotional security was positively associated with children's task behaviours and mediated part of the positive link between these behaviours and teachers' support. Finally, security moderated the relation between support and persistence, such that the effect of teachers' support on persistent behaviours was amplified for relatively insecure children. These results highlight the importance of considering emotional security when examining the interactions between kindergarten children and their teachers.

Utility of extinction-induced response variability for the selection of mands

Functional communication training (FCT; Carr & Durand, 1985) is a commonly used differential reinforcement procedure for replacing problem behavior with socially acceptable alternative responses. Most studies in the FCT literature consist of demonstrations of the maintenance of responding when various treatment components (e.g., extinction, punishment) are present and absent (e.g., Fisher et al., 1993; Wacker et al., 1990). Relatively little research on FCT has (a) evaluated the conditions under which alternative responses are acquired or (b) described procedures with technological precision. Thus, additional research on a cogent technology for response acquisition appears to be warranted. In the current study, we evaluated the efficacy of exposing problem behavior to extinction for inducing response variability as a tool for selecting an alternative response during FCT. Once participants engaged in appropriate alternative responses, the reinforcer identified in the functional analysis as maintaining problem behavior was delivered contingent on the alternative behavior. Results showed that exposing problem behavior to extinction was a useful method for producing alternative behaviors during FCT.     

Encounter with a traditional healer: Western and African therapeutic approaches in dialogue

The paper explores the extent to which cultural aspects contribute to the modalities of human relations and consequently to the qualities of the internal objects and the sense of identity. Therapeutic relationships and techniques, as well as the theories on which they are based, are seen as being equally embedded in their cultural context. An encounter with a traditional African healer offers the author, a western trained European analyst, an opportunity to think about similarities and differences in the therapeutic approach to mental distress, as well as in the training of therapists/healers in the two cultures. Special attention is given to the role of ancestor reverence in African culture. The notion of the ancestors is related to what psychoanalysis describes as internal objects. Cultural differences in the role and importance of verbal language in the therapeutic relationship are described, and the importance and meaning of non-verbal forms of communication are explored.     

Learning from explaining: does it matter if mom is listening?

The goal of the current study was to examine whether explaining to another person improves learning and transfer. In the study, 4- and 5-year-olds (N=54) solved multiple classification problems, received accuracy feedback, and were prompted to explain the correct solutions to their moms, to explain the correct solutions to themselves, or to repeat the solutions. Generating explanations (to selves or moms) improved problem-solving accuracy at posttest, and explaining to mom led to the greatest problem-solving transfer. The study indicates that explanation prompts can facilitate transfer in children as young as 5 years and reveals that it matters if mom is listening.     

Gender differences in facial imitation and verbally reported emotional contagion from spontaneous to emotionally regulated processing levels

Previous studies on gender differences in facial imitation and verbally reported emotional contagion have investigated emotional responses to pictures of facial expressions at supraliminal exposure times. The aim of the present study was to investigate how gender differences are related to different exposure times, representing information processing levels from subliminal (spontaneous) to supraliminal (emotionally regulated). Further, the study aimed at exploring correlations between verbally reported emotional contagion and facial responses for men and women. Masked pictures of angry, happy and sad facial expressions were presented to 102 participants (51 men) at exposure times from subliminal (23 ms) to clearly supraliminal (2500 ms). Myoelectric activity (EMG) from the corrugator and the zygomaticus was measured and the participants reported their hedonic tone (verbally reported emotional contagion) after stimulus exposures. The results showed an effect of exposure time on gender differences in facial responses as well as in verbally reported emotional contagion. Women amplified imitative responses towards happy vs. angry faces and verbally reported emotional contagion with prolonged exposure times, whereas men did not. No gender differences were detected at the subliminal or borderliminal exposure times, but at the supraliminal exposure gender differences were found in imitation as well as in verbally reported emotional contagion. Women showed correspondence between their facial responses and their verbally reported emotional contagion to a greater extent than men. The results were interpreted in terms of gender differences in emotion regulation, rather than as differences in biologically prepared emotional reactivity.     

内隐序列学习意识的具身机制

内隐序列学习意识已有三类理论如全局工作平台理论、神经可塑性理论、新异刺激理论都忽略了身体感受的关键因素, 难以揭示意识产生的根本原因。具身意识理论和研究发现, 运动/情感镜像神经元系统及与自我、认知控制系统的交互, 是初级/高级意识产生的本源, 但未涉及内隐序列学习规则意识这个对人类学习认知至关重要的领域。内隐序列学习研究实质上已接近揭示其学习机制正是感知觉运动具身学习, 其意识机制很可能是感知觉运动/情感具身意识, 并且其意识加工脑区与具身意识脑区有关键重合。未来研究可采用Granger因果大脑网络技术证明内隐序列学习意识的具身本源, 并考察已有三类意识理论的具身基础, 以及探索意识影响因素的具身机制。     

情绪复杂性对精神症状的影响途径及干预技术

情绪复杂性指的是个体情绪体验的多样性和分化度。情绪复杂性影响了精神症状的形成, 它不仅通过改变情绪调节策略的频率和程度来影响精神症状, 而且会影响情绪调节策略和精神症状之间的关系。基于情绪复杂性的干预增加了暴露治疗的疗效。正念能提升情绪复杂性, 但两者的作用机制可能有所差别。情绪复杂性的多角度测量、作用条件及脑机制应成为今后在临床领域的研究方向。     

内观疗法对情绪体验影响的ERP研究

采用事件相关电位技术(ERPs)考察内观疗法对情绪体验影响的变化特点,以探明内观疗法是否引起情绪体验的变化。结果表明,内观组在400-1100ms平均波幅显著大于对照组,在内观组和对照组间,出现了显著的组间差异。由此得出结论,说明了内观疗法对情绪体验产生了影响,主要体现在情绪体验的深度与弥散性上。     

认知和情绪冲突的监控与解决：来自轻度认知损伤的证据

轻度认知损伤(mild cognitive impairment, MCI)是介于正常老化和痴呆之间的过渡阶段。近年来, 执行控制的损伤被认为是MCI的核心特征之一。当前, 在MCI执行控制的领域内, 对冲突监控与解决的特征及其神经机制的研究较少。本研究拟通过认知及情绪冲突实验范式, 结合脑成像技术, 探讨遗忘型MCI (amnestic MCI, aMCI)认知和情绪冲突的监控与解决的特征及相应的脑激活模式; 通过对比aMCI和正常老年人在认知和情绪冲突任务中激活的神经环路, 考察aMCI是否在执行加工的神经网络上存在激活异常。在上述研究基础上, 研究者拟探讨aMCI在执行控制的冲突监控与解决上是否存在一般性的损伤机制, 同时试图寻找aMCI在执行控制的冲突监控与解决方面的认知及神经生物学标记。这对深入理解痴呆的发病进程并有针对性的开展痴呆的早期识别与干预具有重要的理论意义和实践意义。     

心理复原的机制：来自特质性复原力个体的证据

心理复原(力)是指个体在经历对生命具有威胁的事件或严重的创伤后仍然能回复到良好适应状况的心理发展现象。基于能力取向的文献表明, 积极情绪性、情绪调节是特质性复原力机制研究的重要内容; 脑岛和前额叶(特别是vmPFC和OFC)是其敏感的脑区; 作用于杏仁核脑区的5-羟色胺转运蛋白与特质性复原力密切相关。基于这些研究结果, 提出积极情绪与(自动、有意)情绪调节交互作用的双重加工理论和根据实际需要调节情绪的情绪灵活性理论。未来的研究应该就情绪记忆、人格特质等在心理复原中的作用进行探讨。
