Implicit associations between smoking and social consequences among smokers in cessation treatment

Explicit expectations of the negative and positive social consequences of smoking are likely to have substantial influence on decisions regarding smoking. However, among smokers trying to quit, success in smoking cessation may be related not only to the content of expectancies about smoking's social effects but also to the ease with which these cognitive contents come to mind when confronted with smoking stimuli. To examine this possibility, we used the implicit association test (IAT) [Greenwald, A. G., McGhee, D. E., & Schwartz, J. L. K. (1998). Measuring individual differences in implicit cognition: The implicit association test. Journal of Personality and Social Psychology, 74, 1464-1480] to assess implicit cognitive associations between smoking and negative vs. positive social consequences among 67 heavy social drinkers seeking smoking cessation treatment in a randomized clinical trial. Results showed that the relative strength of implicit, negative, social associations with smoking at baseline predicted higher odds of smoking abstinence during treatment over and above the effects of relevant explicit measures. The only variable that significantly correlated with IAT scores was the density of smokers in participants' social environment; those with more smoking in their social environment showed weaker negative social associations with smoking. Results suggest implicit cognition regarding the social consequences of smoking may be a relevant predictor of smoking cessation outcome.     

Between memory and destiny: Repetition1

This essay focuses mainly on the topic of repetition (agieren)—on its metapsychological, clinical, and technical conceptions. It contains a core problem, that is, the question of the represented, the nonrepresented, and the unrepresentable in the psyche. This problem, in turn, brings to light the dialectical relation between drive and object and its specific articulation with the traumatic. The author attributes special significance to its clinical expression as ‘destiny’. He points out a shift in the theory of the cure from recollection and the unveiling of unconscious desire, to the possibility of understanding ‘pure’ repetition, which would constitute the very essence of the drive. The author highlights three types of repetition, namely, ‘representative’ (oedipal) repetition, the repetition of the ‘nonrepresented’ (narcissistic), which may gain representation, and that of the ‘unrepresentable’ (sensory impressions, ‘lived experiences from primal times,’‘prelinguistic signifiers,’‘ungovernable mnemic traces’). The concept‐the metaphor‐drive embryo brings the author close to the question of the archaic in psychoanalysis, where the repetition in the act would express itself. ‘Another unconscious’ would zealously conceal the entombed (verschüttet) that we are not yet able to describe‐the ‘innermost’ rather than the ‘buried’ (untergegangen) or the ‘annihilated’ (zugrunde gegangen)‐through a mechanism whose way of expression is repetition in the act. With ‘Constructions in analysis’ as its starting point, this paper suggests a different technical implementation from that of the Freudian construction; its main material is what emerges in the present of the transference as the repetition of ‘something’ lacking as history. The memory of the analytic process offers a historical diachrony whereby a temporality freed from repetition and utterly unique might unfold in the analysis. This diachrony would no longer be the historical reconstruction of material truth, but the construction of something new. The author briefly introduces some aspects of his conception of the psyche and of therapeutic work in terms of what he has designated as psychic zones. These zones are associated with various modes of becoming unconscious, and they coexist with different degrees of prevalence according to the psychopathology. Yet each of them will emerge with unique features in different moments of every analysis, determining both the analyst's positions and the very conditions of the analytic field. The zone of the death drive and of repetition is at the center of this essay. ‘Pure’ repetition expresses a time halted by the constant reiteration of an atemporal present. In this case, the ‘royal road’ for the expression of ‘that’ unconscious will be the act. The analyst's presence and his own drive wager will be pivotal to provide a last attempt at binding that will allow the creation of the lost ‘psychic fabric’ and the construction, in a conjectural way, of some sort of ‘history’ that may unravel the entombed (verschüttet) elements that, in these patients' case, come to the surface in the act. The analysand's ‘pure’ repetition touches, resonates with something of the new unconscious of the analyst. All of this leads the author to underline once again the value of the analyst's self‐analysis and reanalysis in searching for connections and especially in differentiating between what belongs to the analyst and what belongs to the analysand. A certain degree of unbinding ensures the preservation of something ungraspable that protects one from the other's appropriation.     

Developmental changes in self-corrected elaboration effects on incidental memory

Abstract:  Two experiments were carried out to investigate the changes across age groups in the effects of self-corrected elaboration on incidental memory. Each participant performed an orienting task involving three conditions: self-corrected, self-generated and experimenter-provided elaboration. The orienting task was followed by free recall tests. In Experiment 1, the participants were sixth-grade and second-grade students. For sixth-grade students the self-corrected elaboration led to a better free recall than the other two elaborations, whereas for the second-grade students, no difference was observed between any of the three elaborations. In Experiment 2, using a longer word list than that in Experiment 1, the participants were undergraduates. The self-corrected and self-generated elaborations led to a better free recall than the experimenter-provided elaboration, and no difference between the former two elaborations was observed. The results obtained from these two experiments were interpreted as showing that the effectiveness of a self-corrected elaboration depends on the participants' age.     

Working memory deficit in children with mathematical difficulties: a general or specific deficit?

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both mathematical and reading difficulties were compared with 47 age-matched and 50 younger controls (9-year-olds) on a number of working memory tasks. Compared with the age-matched controls, both groups of children with MDs performed worse on tasks tapping the central executive (e.g., visual matrix span) and the phonological loop (e.g., word span). More important, the MD group performed worse than the younger controls on the counting span task, whereas the group with comorbid mathematical and reading difficulties performed worse on the counting span task and the visual matrix span task. These findings provide support for the assumption that children with MDs have a working memory deficit. More specifically, children with MDs have a central executive deficit connected to concurrent processing and storage of numerical and visual information.     

IAT范式下自尊内隐性的再证明

该研究用IAT测量了被试的内隐自尊,并通过操纵被试在不同的认知负荷条件下进行外显自我评价来考察外显自我评价和内隐自尊之间的关系。得到的结论是,在低认知负荷条件下进行外显自我评价时,外显自我评价和内隐自尊没有表现出一致性;在高认知负荷条件下进行外显自我评价时,外显自我评价和内隐自尊表现出一致性。该研究在IAT范式下表明了内隐自尊和外显自尊的分离,内隐自尊具有无意识性和自动化的特点。

Life-long environmental enrichment differentially affects the mnemonic response to estrogen in young, middle-aged, and aged female mice

The present study was designed to examine whether life-long exposure to standard or enriched housing affects the ability of estrogen to improve spatial and object memory throughout the lifespan. Three-week-old female mice were maintained in standard or enriched housing up to and through ovariectomy and behavioral testing at 5, 17, or 22 months of age. Spatial memory was tested in the Morris water maze and object memory was tested using an object recognition task. Immediately after training each day, mice were injected intraperitoneally with vehicle or 0.2 mg/kg 17beta-estradiol. Among young females, object recognition was enhanced by estradiol alone, an effect that was reduced by enrichment. In contrast, spatial water maze performance was impaired by estradiol alone, but improved by the combination of both estradiol and enrichment. At middle-age, object recognition was enhanced by estradiol or enrichment alone, and the combination of both treatments. Spatial memory in the water maze was also improved by both treatments at middle-age, but the beneficial effects of estradiol were limited to standard-housed females. Finally, whereas enrichment in aged females significantly enhanced performance in both tasks, estradiol had no effect at this age in either task. In total, the data indicate that life-long enrichment can significantly alter the extent to which estradiol affects memory in mice throughout the lifespan. Importantly, the interaction between these treatments is highly dependent on age and type of memory tested.     

The hidden sides of self-esteem: Two dimensions of implicit self-esteem and their relation to narcissistic reactions

Implicit, or nonconscious, self-esteem is often assumed to involve a unidimensional evaluation of the self. Our studies demonstrate that implicit self-esteem is in fact multifaceted and can be divided into at least two dimensions, which we term self-liking and self-attractiveness. Among participants for whom narcissistic thoughts and feelings were experimentally activated, we found that the two dimensions of implicit self-esteem were differentially associated with self-reported narcissism (Study 1) and feelings of aggressiveness (Study 2). In particular, narcissistic reactions were predicted by the combination of a high level of implicit self-attractiveness and a low level of implicit self-liking. These findings add to the growing understanding of the complexities of implicit self-esteem.     

Stereotype internalization and women’s math performance: The role of interference in working memory

It has long been argued that stigmatized individuals can ultimately internalize the stereotype alleging their inferiority. The present article investigated whether the internalization of the reputation of math inferiority that targets women can affect their math performance and whether this influence is caused by a disruption of working memory. A first study showed that stereotype endorsement had a significant impact on women’s statistic performance by lowering their self-evaluation of math ability even when controlling for prior achievement. A second study was designed to assess the possibility that the lower math performance displayed by women with low self-evaluation of math ability was due to interference in working memory. Using a dual task paradigm, this study showed that indeed women with low math self-evaluation displayed more errors and spent more time solving additions than women with high math self-evaluation, but mainly on difficult items of the dual task. The findings, which are congruent with an explanation in terms of a temporary disruption of working memory, are discussed.     

听障人群的工作记忆机制

听障人群听觉通道受损,使用手语交流,提供了独特的切入点来探讨工作记忆的结构和功能。研究表明,听障人群具备在功能上与正常人的语音环路平行的手语复述机制。通过发声训练,听障人群也可采用语音编码,即语音环路可被通达。听障人群具有与正常人相当的语言工作记忆资源,但是这种资源在具体使用时受视觉通道处理特性的限制。越来越多的研究支持互补理论,认为手语的使用增强了听障人群非语言的视空间处理能力。
