Ageing and thought suppression performance: Its relationship with working memory capacity,habitual thought suppression and mindfulness

A study investigated how the ability to suppress thoughts in the laboratory was affected by type of thought suppressed (positive, negative, neutral), participants’ age and working memory capacity (WMC). Linked variables (Use of thought suppression, social desirability, and mindfulness) were measured to assess whether they modified susceptibility to thought intrusion.Younger, middle aged and older adults suppressed three different valenced thoughts in a counterbalanced order for 5-min per thought. Participants then completed a WMC task and questionnaire measures of the linked variables.Valence had no effect on intrusions. WMC was positively related to intrusions; higher WMC corresponded to greater intrusions. Age was negatively related to intrusions; with increasing age intrusions decreased. Hierarchical regression showed only age and backward digit span (WMC) significantly predicted intrusions. The relationship between WMC and intrusions was not moderated by age. WMC and age both independently predict level of intrusion, and no synergistic effect was found.     

Associations between childhood adversity and daily suppression and avoidance in response to stress in adulthood: can neurobiological sensitivity help explain this relationship?

Background and objectives: Although it has been postulated that psychological responses to stress in adulthood are grounded in childhood experiences in the family environment, evidence has been inconsistent. This study tested whether two putative measures of neurobiological sensitivity (vagal flexibility and attentional capacity) moderated the relation between women’s reported exposure to a risky childhood environment and current engagement in suppressive or avoidant coping in response to daily stress.

Design and methods: Adult women (N?=?158) recruited for a study of stress, coping, and aging reported on early adversity (EA) in their childhood family environment and completed a week-long daily diary in which they described their most stressful event of the day and indicated the degree to which they used suppression or avoidance in response to that event. In addition, women completed a visual tracking task during which heart rate variability and attentional capacity were assessed.

Results: Multilevel mixed modeling analyses revealed that greater EA predicted greater suppression and avoidance only among women with higher attentional capacity. Similarly, greater EA predicted greater use of suppression, but only among women with greater vagal flexibility.

Conclusion: Childhood adversity may predispose individuals with high neurobiological sensitivity to a lifetime of maladaptive coping.     

‘Telepathic’ phenomena and separation anxiety

By discussing a treatment characterized by its difficult ending, the author strives to show the dynamic impact of separation on phenomena that can be seen as ‘telepathic’. Led to develop some inalienable attachment to her analyst in the primary transference, the analysand found herself caught up in the contradiction of her visceral dread of dependency, which compelled her to interrupt the work in progress. She then began to work out her analyst's comings and goings and to run into him in public places, as if to be assured of his immovability. This phenomenon arose with high frequency as the effect of some idealization of the maternal object aiming to deny the spatiotemporal gap. The chance that the experience of rejection via indifference may be repeated also entailed the transferential unfurling of a fantasy involving a double, undifferentiation counterbalancing the lived experience of separation. Furthermore, a ‘telepathic’ dream occurred as confirmation of this twin relationship which illustrates the analysand's refusal to renounce her narcissistic object. Projective identifications, agglutinated ego nuclei along with primitive cross‐identifications could, among other concepts, account for such phenomena which are projective in nature yet real all the same. Such mechanisms could have the power to relay thoughts the moment undifferentiated parts of the ego – if not unborn parts of the self – were activated in a potentially symbiotic zone. Marked by a feeling of dispossession, the analyst's countertransference not only seemed to underscore this hypothesis, it also gave a partial explanation for it. Until the analyst could recognize his own nostalgia for a symbiotic relationship, he had to encourage the occurrence of those unexpected meetings which stemmed from a convergence between the transference and the countertransference.     

Increased distractibility in schizotypy: Independent of individual differences in working memory capacity?

Individuals with schizophrenia typically show increased levels of distractibility. This has been attributed to impaired working memory capacity (WMC), since lower WMC is typically associated with higher distractibility, and schizophrenia is typically associated with impoverished WMC. Here, participants performed verbal and spatial serial recall tasks that were accompanied by to-be-ignored speech tokens. For the few trials wherein one speech token was replaced with a different token, impairment was produced to task scores (a deviation effect). Participants subsequently completed a schizotypy questionnaire and a WMC measure. Higher schizotypy scores were associated with lower WMC (as measured with operation span, OSPAN), but WMC and schizotypy scores explained unique variance in relation to the mean magnitude of the deviation effect. These results suggest that schizotypy is associated with heightened domain-general distractibility, but that this is independent of its relationship with WMC.

客体工作记忆研究的现状与展望

近年来, 大量的研究分别从行为和认知神经心理学的角度探讨了客体工作记忆的特性。行为水平上, 相关研究主要集中在客体工作记忆研究范式、客体在视觉工作记忆中的存储方式、视觉工作记忆容量等方面, 而客体工作记忆存储的争论体现在客体工作记忆存储的“强捆绑”假设、“特征-捆绑统一存储”假设、双重存储机制假设, 以及客体的捆绑等方面。认知神经水平上, 颞叶、枕叶和顶叶在视觉工作记忆中的作用不同, 顶叶、颞叶和前额叶在工作记忆特征捆绑和加工中起重要作用。

Dreaming as a primordial state of the mind: The clinical relevance of structural faults in the body ego as revealed in dreaming1

Thetherapeuticactionofpsychoanalysis, attributedformanyyearstotheinterpretation of the repressed libido, has shifted its focus to object relationships. Some modern analysts maintain that the primary factor of psychic change is the new model of object relationship provided by analysis, and do not consider signifi cant the knowledge of episodes comprising implicit memories, whose irrecoverable nature is demonstrated by neuroscience. Nevertheless, the author proposes that the knowledge of specifi c archaic events, useless as their interpretation may be, offers a glimpse of the make‐up of the mind, contributing to the improvement of the empathy indispensable for inducing changes in the patient. Episodes linked to absolute narcissism, in the beginnings of the body ego, which do not appear either in associations or in transference, emerge in dreams. Neuroscience has made possible the understanding of aspects of dreaming capable of providing a glimpse of the genesis of the ego, whose development from the bodily phase of absolute narcissism to the psychic object phase can thus be traced. The unearthing of the genesis of primary structural faults in dreaming furnishes the analyst with an estimate of the possibilities for development of the ego, and this knowledge provides fi ne tuning capable of guiding the analyst's conduct. A clinical case illustrates how these phenomena occur, showing the intersubjective relationship as the silent primary generator of psychic changes, consolidated and developed secondarily by means of the analytical dialogue.     

工作记忆中“组块”概念的演化及理论模型

在Miller提出“神奇的数字7±2”之后,“块”被很多理论作为个体工作记忆加工过程中具有稳定结构并可用于衡量记忆容量的单位。但随着研究者对“组块”研究的深入,他们对组块的定义也在发生着改变。与此同时,不少研究发现个体的年龄阶段与其主要采用的组块层级相对应,但尚不清楚组块层级的转换是否存在固定的年龄区间,且对组块机制的解释仍存在分歧。因此本文针对组块定义的发展与演变、年龄阶段特征及其机制三方面展开综合讨论。未来的研究可以更多探讨长时记忆在工作记忆组块运行机制中的作用,完善不同年龄阶段个体的组块特征,以及怎样发挥复述策略和“少即是多”原则在组块过程中的优势等问题。     

Translating External Knowledge to Team Creativity in Turbulent Environments: The Role of Absorptive Capacity and Knowledge Integration

In seeking to understand factors contributing to team creativity in dynamic environments, we explored the role of external knowledge search on team creativity through absorptive capacity and knowledge integration. We tested our hypotheses with a sample of 96 teams involving 421 employees in China. Results demonstrated that external knowledge search related positively to team creativity, fully mediated by both absorptive capacity and knowledge integration. In addition, environmental dynamism played a moderating role in the relation between external knowledge search and absorptive capacity, as well as in the relation between external knowledge search and knowledge integration. We discussed the implications of these findings for research and practice.
