The role of working memory in achievement goal pursuit

The present research examined the role of working memory in the pursuit of qualitatively different achievement goals. Pursuit of a mastery-approach goal entails a focus on developing self-referential competence while a performance-approach goal entails a focus on demonstrating normative competence. Across two experiments it was found that, when working memory is loaded, individuals pursuing a mastery-approach goal experienced larger performance decrements than individuals pursuing a performance-approach goal or those in a no-goal control. It was also found that reliance upon working memory intensive strategies (explicit strategies) was more evident for those in a mastery-approach condition, whereas reliance upon less working memory intensive strategies (implicit strategies) was more evident for those in the performance-approach condition. Results suggest that a motivated focus on developing self-referential skill relies heavily on working memory, facilitated by the use of deliberative, ‘step-by-step’ strategies during goal pursuit. Conversely, a focus on demonstrating normative skill depends less on working memory, facilitated by the use of more heuristic ‘short-cut’ strategies during goal pursuit. These findings show, for the first time, that working memory plays an important, but selective, role in achievement goal pursuit.     

Exposure to Violence and Expressions of Resilience in Central American Women Survivors of War

Abstract

This article focuses on expressions of resilience in a sample of 30 women from El Salvador and Guatemala who survived multiple types of violence, including war trauma, before taking refuge in the US. Traumatic impact, recovery, and resilience were assessed using the Multidimensional Trauma Recovery and Resilience Interview (MTRR-I) and rating scale, MTRR-99. Exposure to violence was assessed by the Harvard Trauma Questionnaire and the MTRR-I. The study established that the women had suffered multiple and extreme forms of violence prior to and en route to the United States and yet were highly resilient on multiple MTRR domains when compared with a US sample. Implications for future research for assessment of trauma exposure and resilience among war-afflicted populations are discussed.     

Is attention necessary for perceiving gaze direction? It depends on how you look at it: Evidence from the locus-of-slack method

Several researchers have studied how we process and perceive gaze direction. However, it is still unclear at which perceptual stage of gaze processing (encoding or/and categorization), attention is required to judge gaze direction. We report a study in which we manipulated the difficulty of gaze perceptual judgements (easy vs. difficult) and used the locus-of-slack method to test the role of different types of attention (spatial and central) in the encoding and categorization of gaze direction. In Experiment 1 we used the spatial cueing paradigm to investigate if gaze direction judgements can be carried out while spatial attention is diverted. In Experiment 2 we used the psychological refractory period (PRP) paradigm to determine whether judgement of gaze direction involves central attention processes. The findings demonstrate that gaze judgements require input attention (both for the encoding and categorization stage) but not central attention. The implications of the results are discussed.     

Emotions,narrative and change

There is a wide agreement that emotions are central to the evaluation and understanding of change processes in psychotherapy. Unfortunately, most of the debate on the role of emotions has been influenced by the reductionist view of ‘psychophysiological symbolism’ (Averill 1996). We defend the position that, in order to understand their role in psychotherapy fully, we need to move in the direction of a more complex view of emotions. This paper presents a view of emotionsas social constructed phenomena operating via language and narrative. We present research suggesting that these narratives may be an essential process for understanding psychological disorders, how these disorders are developed and, finally, how they can be changed.     

'Gonnae no' dae that!'1 the internal and external worlds of the delinquent adolescent

In understanding delinquency in adolescence the key theoretical papers on the role of oedipal resolution and superego development remain essential and are summarized. To this we need to add our knowledge of trauma and of developmental deficit if we are to offer appropriate strategies for young delinquents and to be able to select those for whom therapy, intervention with the network or containment are appropriate. The defence of activity, commonplace in adolescence, becomes too easily enacted in the network around the delinquent and in the public domain, and thoughts are given on this process and on the roles open to the psychotherapist.

Afin de mieux cerner la délinquance chez l'adolescent, l'auteur passe en revue certains textes théoriques fondamentaux et toujours d'actualité sur l'importance de la dissolution du complexe d'?dipe et de la mise en place du Surmoi. À ces thèmes il convient d'ajouter ce que nous connaissons de l'impact des traumatismes et des défaillances développementales si nous voulons offrir au jeune délinquant des stratégies adéquates et identifier ceux pour qui une modalité particulière d'intervention - thérapie, prise en charge en réseau, structure contenante - semble la mieux indiquée. La défense par mise en acte, fréquente À l'adolescence, trouve trop facilement un écho dans le réseau d'intervenants autour de l'adolescent et dans le champ social ; l'auteur développe ses réflexions À ce sujet et explore les rôles que le thérapeute peut être amené À jouer.     

Transference,triangles and trajectories

In this article the author addresses the issue of the need to lessen the likelihood of a regressive transference neurosis in short-term therapy. He examines the role that active interpretation of the transference can have in shaping the transference so that it remains at the level of the transference that is ubiquitous. He explores the relationship between such an active interpretative approach and the need for the therapist to be empathic and sensitive to the patient and to allow space for a patient's independent discoveries. The author describes the role of the Central Therapeutic Focus, as a constellation of the Triangles of Insight, in guiding the therapist to select those manifestations of the transference to interpret, and in enabling the therapist to retain a stance that is sensitive and empathic. The Central Therapeutic Focus is contrasted with the concept of the Central Issue, and with the latter's more specific attention to the contribution that it makes to the therapist's communication of their empathic understanding of the patient's difficulties. The nature of the relationship between the therapist and the patient in short-term therapy is explored further and the connections between companionable interaction, ego-relatedness and the matrix of the transference are outlined. The author proceeds to consider the nature of the process of working through in short-term therapy and of the need to attend to the patient's external world as the place in which this can occur. The contribution of the Central Therapeutic Focus in shaping the trajectory through which the patient and therapist attend to the external world is examined. This in turn is linked to the identification of a patient's ordinary solution to their problem as a means of resolving their Dilemma. The article concludes with a case example that illustrates these themes.     

一个中枢炎性免疫诱发长时程抑郁样行为的新模型

脂多糖(lipopolysaccharide, LPS)免疫激活模型是研究抑郁症细胞因子假说的重要动物模型, 目前国际上常用外周单次LPS注射诱发抑郁样行为, 但该模型中抑郁样行为持续仅有数小时。为建立诱发较长时程抑郁样行为的免疫激活动物模型, 本研究尝试侧脑室注射LPS激活大鼠中枢免疫炎性反应, 考察单次以及重复中枢LPS注射诱发抑郁样行为的效果, 以及中枢炎性免疫诱发行为改变的时程。结果显示：单次中枢LPS注射后24 h只能诱发旷场自发活动和探索行为下降等部分抑郁样行为, 未能诱导糖水偏好下降和悬尾不动时间增加; 3次重复注射则在末次LPS注射后24 h表现出显著的糖水偏好下降, 自发活动和探索行为减少, 悬尾不动时间增加等行为。且自发活动、探索行为减少和悬尾不动时间增加能够延续至末次LPS注射后72 h。这些结果表明脑室重复LPS注射可诱发较长时程的抑郁样行为, 这种新的中枢炎性免疫激活诱发的抑郁症模型, 为研究抑郁症炎性免疫机制提供了更为有效的动物模型, 有助于深入探讨行为和免疫功能间的复杂关系。     

The components of visual attention and the ubiquitous Simon effect

Spatial responding is influenced by the degree of correspondence between the stimulus–response (S–R) code activated by the target's task-irrelevant location and the S–R code activated by the target's non-spatial, task-relevant feature. A generally accepted explanation of this “Simon effect,” named after its discoverer, is that there is a natural tendency to respond towards the source of stimulation. First we will review the ubiquity of the Simon effect. Then we will review the literature, including our own studies when appropriate, that has explored the relationship between the Simon effect and the components of attention: alertness, orienting and executive control, with an emphasis on visual orienting. The Simon effect is reduced when participants are not alert and when executive control is effective in filtering out the irrelevant location information. When attention is oriented endogenously, or is captured exogenously by uninformative peripheral stimulation, the Simon effect is additive with attentional facilitation (i.e., the Simon effect is the same magnitude for targets presented at attended and unattended locations). Yet, some forms of orienting, such as orienting directed by gaze and biased by inhibition of return, modulate the Simon effect. We will explore the implications of these patterns of additivity and interaction for our understanding of both the Simon effect and spatial attention.     

Detrimental effects of using negative sentences in the autobiographical IAT

The autobiographical Implicit Association Test (aIAT) is a method that accurately identifies which one of two contrasting autobiographical events is true for the subject. The aIAT indexes the real autobiographical event (e.g. I was in Paris for Christmas) on the basis of the facilitating effect because it maps the real autobiographical event with true sentences (e.g. I am in front of a computer) on the same motor response. In this paper we focus on the conditions under which the autobiographical IAT accurately and reliably identifies autobiographical memories. A recent study showed a reduction in the accuracy of the aIAT when negative sentences are used. We have investigated the detrimental effect on aIAT accuracy of such negative sentence items, used to describe autobiographical events, compared with affirmative sentence items. While we highlight the reliability of the results obtained using negative sentences, we also show that the use of affirmative sentences in describing autobiographical events guarantees high accuracy and reliability of results in identifying the true autobiographical event. Finally, we summarise the criteria for preparing stimuli for an effective aIAT in order to maximise correct classifications of individual subjects.     

Playing the Simon game: Use of the Simon task for investigating human information processing

A little more than 40 years ago, J. R. Simon and colleagues introduced what is now called the Simon task, which yielded a correspondence effect known as the Simon effect. In this paper, I set Simon's contribution in the context of research on stimulus-response compatibility. The novel contribution of the Simon task is described, along with foundational findings using the task that Simon and colleagues reported. I acknowledge the significance of Simon's (1990) review chapter in generating my own interests in the Simon task and describe four selected lines of research from my lab that have been a result of those interests. The article concludes with a brief tribute to Simon and his contribution to experimental psychology.
