Determinants of attentive blank stares. An EFRP study

Attentive blank stares mean a failure to notice changes in a visual scene, despite looking at the area of change (Caplovitz, Fendrich, & Hughes, 2008). In this research project we have shown that people differ in terms of attentive blank stare incidences. Novices tend to fail to notice changes in the target area more often than experts. This effect is greater in persons with low visual working memory capacity (VWMC) than with high VWMC. In addition, in a group of novices with low VWMC, attentive blank stares are more frequent compared to a group with high VWMC. Attentive blank stares did not disappear even after the high VWMC group were given expertise training. With the method of eye-fixation-related potentials (EFRP) we analyzed the amplitude of lambda response, which may reflect the state of the attentional system, during encoding information about a change, prior to a decision whether a change has occurred or not. We demonstrate that the cases of attentive blank stares are accompanied by significantly lower amplitude of the lambda response compared with cases involving change detection. In addition, we discovered greater lambda responses in a group with expertise who noticed the change than in novices. The EFRP record coming from occipital electrodes in the 80–180 ms window function was marked by left-sided asymmetry in the cases of change detection and by right-sided asymmetry in the cases of attentive blank stares.     

Happiness increases verbal and spatial working memory capacity where sadness does not: Emotion,working memory and executive control

The effects of emotion on working memory and executive control are often studied in isolation. Positive mood enhances verbal and impairs spatial working memory, whereas negative mood enhances spatial and impairs verbal working memory. Moreover, positive mood enhances executive control, whereas negative mood has little influence. We examined how emotion influences verbal and spatial working memory capacity, which requires executive control to coordinate between holding information in working memory and completing a secondary task. We predicted that positive mood would improve both verbal and spatial working memory capacity because of its influence on executive control. Positive, negative and neutral moods were induced followed by completing a verbal (Experiment 1) or spatial (Experiment 2) working memory operation span task to assess working memory capacity. Positive mood enhanced working memory capacity irrespective of the working memory domain, whereas negative mood had no influence on performance. Thus, positive mood was more successful holding information in working memory while processing task-irrelevant information, suggesting that the influence mood has on executive control supersedes the independent effects mood has on domain-specific working memory.     

A virtue ethical approach to decisional capacity and mental health

It is a common assumption that lack of autonomy is incompatible with decisional capacity and mental health. However, there are two general conceptions of autonomy, one value-neutral and the other value-laden, which imply different notions of mental health. I argue that the value-neutral notion of autonomy is independently inadequate and that it also provides an inadequate foundation for judging whether someone is decisionally incapable or mentally disordered. I propose an alternative, value-laden account which posits ten capabilities required for basic human functioning. I then defend this account against objections and highlight its practical utility in designing optimal treatment.     

利益冲突情境中社会行为的自动激活:合作还是利己?

合作与利己是利益冲突情境中个体的基本行为模式。在理性假设所主导的框架下,利己行为被看作是人类的本能反应。然而,近期的观点指出,人类的合作本质上是一种自动化的行为反应。无意识、认知能力、自我损耗以及神经科学等领域的理论和研究支持像合作这样复杂的社会行为可以自动地激活。未来研究除了需要继续揭示行为自动化的结果是利己还是利他之外,还需要确定社会合作自动化产生的机制与条件。     

Working memory capacity and the spacing effect in cued recall

Spacing repetitions typically improves memory (the spacing effect). In three cued recall experiments, we explored the relationship between working memory capacity and the spacing effect. People with higher working memory capacity are more accurate on memory tasks that require retrieval relative to people with lower working memory capacity. The experiments used different retention intervals and lags between repetitions, but were otherwise similar. Working memory capacity and spacing of repetitions both improved memory in most of conditions, but they did not interact, suggesting additive effects. The results are consistent with the ACT-R model’s predictions, and with a study-phase recognition process underpinning the spacing effect in cued recall.     

Individual differences in reappraisal ability: Links to reappraisal frequency, well-being, and cognitive control

Reappraisal is generally viewed as an adaptive emotion regulation strategy. Reappraisal frequency has been associated with greater well-being, and reappraisal ability is thought to be composed of several crucial cognitive control processes. However, the relationships among reappraisal ability, reappraisal frequency, well-being, and various cognitive control processes have not yet been determined. In this study, we experimentally examined individual differences in reappraisal ability (RA), and also assessed reappraisal frequency, well-being, and several cognitive control processes. We observed a positive relationship between RA, reappraisal frequency, and well-being. RA was also related positively to working memory capacity and set-shifting costs, and marginally related to abstract reasoning. These findings have important implications for understanding the cognitive components and affective outcomes of RA.     

Children's use of semantic organizational strategies is mediated by working memory capacity

In adults, the ability to apply semantic grouping strategies has been found to depend on working memory. To investigate this relation in children, two sort-recall tasks (one without and one with a grouping instruction) were administered to 6–12-year-olds. The role of working memory was examined by means of mediation analyses and by assessing whether children who successfully used the semantic grouping strategy had higher working memory capacity than did children who did not show such strategy use. Only children aged 8–12 were able to successfully use semantic grouping strategies (and 8–9-year-olds only after instruction), while strategy use was absent in 6–7-year-olds. Both types of analysis involving working memory suggested that, also in children, working memory (and not short-term memory) mediates the development of successful use of the semantic grouping strategy during both encoding and retrieval.     

The impact of anxiety on analogical reasoning

The effect of state anxiety on analogical reasoning was investigated by examining qualitative differences in mapping performance between anxious and non-anxious individuals reasoning about pictorial analogies. The working-memory restriction theory of anxiety, coupled with theories of analogy that link complexity of mapping with working-memory capacity, predicts that high anxiety will impair the ability to find correspondences based on relations between multiple objects relative to correspondences based on overlap of attributes between individual objects. Anxiety was induced in one condition by a stressful speeded subtraction task administered prior to the analogy task. Anxious participants produced fewer relational responses and more attribute responses than did non-anxious participants, both in the absence of explicit instructions to find relational mappings (Experiment 1) and after receiving such instructions (Experiment 2). The findings support the postulated links among anxiety, working memory, and the ability to perform complex analogical mapping.     

On Phallicism; Developmental Aspects,Neutralization, Sublimation and Defensive Phallicism

Many children in need of psychotherapy are latency-age boys who have little or no contact with their fathers. Their problems typically include low self-esteem, identity problems, depression, difficulties in peer relationships, and aggression. Clinical material illustrates that the consequences for the child of fatherlessness depend on many factors, among them the mother's attitude to the father and other mature males. If the mother devalues all men, her son has little space to grow into a healthy adult. The male therapist may be experienced as a threat to the mother-son union, which may render his efforts to help the boy fruitless. If, in contrast, the mother's experiences of her own father and other men are more positive, her pride in her son's masculinity may strengthen his need to find support for his male development. These observations are discussed as affecting the capacity for triadic object representations in mothers and sons.
