文化视域下文化神经科学学科主张与检讨

文化神经科学是在宏大的文化背景下来全面深入考察个体的"心理、行为与脑认知机制"之间规律的一门学科。文化神经科学所倡导的神经-文化交互作用模型表明该学科以融合视野引领心理学研究范式的变革成为可能。同时,从文化学视野来审视,亦折射出其在文化学层面的短板,即人文精神与文化意蕴在"文化"名义下日渐式微。     

国内近十年来意识和无意识关系研究的新成就

近十年来,国内掀起了从自然科学途径进行意识和无意识对比研究的新热潮,尤其在实验范式的引进、修正、完善和模型建构方面,做出了中国学者自己的贡献。错误记忆、内隐时间及不注意视盲等新领域的触及代表了国内学者在意识研究内容上的丰富。“钢筋水泥”、“意识涌现”及“车站监视室”等模型的提出,代表了中国学者在意识研究理论方面的创新。当前国内意识研究与国外基本同步,但存在着“研究领域泛化,神经机制探讨有限,跨学科整合力度有待深化”的问题。     

Rethinking the paradigm of enterprise: A global and evolutionary perspective

The most elementary law of nature, the principle that best explains how the world works, is that actions have consequences. The consequences of enterprise (or business) will be as profitable or detrimental as the actions behind them. The rapidly approaching new millennium forces society to assess where we are (the consequences) and how we got here (the actions). The standard of living in the western world is a direct consequence of past and present enterprise, but the actions taken to get to this plateau and their associated costs may far over‐shadow the gains. A major issue facing those who study the development and evolution of enterprise is whether past merits and mistakes can be used to develop a new paradigm that is more reflective of what is currently experienced and most likely to occur in the future.

This paper discusses some of the shortcomings in current economic thinking, how current developments in economic thinking need to become the norm and the future of socio‐ecologically behavior and patterns of growth for enterprise.     

语义相似性与类别大小对图-词干扰范式下语义效应的影响

采用基本水平命名和类别水平命名任务, 通过2个实验, 考察了图-词之间的语义相似性与类别大小对图-词干扰范式下语义效应的影响。实验1发现, 图片命名时间在语义相似性高的干扰词条件下显著快于在语义相似性低的干扰词条件下, 但这种效应只出现在基本水平命名任务中, 未出现在类别水平命名任务中。图-词之间的语义相似性高低对低熟悉图片命名影响大, 对高熟悉图片命名影响小。实验2显示, 语义关联的干扰词对图片的基本水平命名产生了语义干扰效应, 对图片的类别水平命名产生了语义促进效应。类别大小强化了语义效应：类别大, 图片的基本水平命名的语义干扰效应更大, 图片的类别水平命名的语义促进效应更强。整个研究表明, 图-词之间的语义关联的强度影响语义效应的方向, 图-词之间的语义关联的广度影响语义效应的强弱。需要结合多种理论来解释图-词之间的语义相似性和类别大小对图-词干扰范式下语义效应的影响。     

The role of associative strength in children's false memory illusions

The effects of associative strength on rates of 7- and 11-year-old children's true and false memories were examined when category and Deese-Roediger-McDermott (DRM) lists were used to cue the same critical lure. Backward associative strength (BAS) was varied such that the category and DRM lists had the same strength (DRM=category), DRM lists had more BAS (DRM>category), or category lists had more BAS (DRM<category). If BAS drives children's false memories then BAS, not the type of relation across items in a list, should determine false memory production. The results confirmed this prediction using both recall and recognition measures: (1) both true and false memories increased with age, (2) true memory was better for category than DRM lists but there were no differences for false memory, and (3) at all ages, false memories varied predictably with changes in BAS but were unaffected by list-type manipulations. These findings are discussed in the context of models of false memory development.     

Valence and the development of immediate and long-term false memory illusions

Across five experiments we examined the role of valence in children's and adults’ true and false memories. Using the Deese/Roediger-McDermott paradigm and either neutral or negative-emotional lists, both adults’ (Experiment 1) and children's (Experiment 2) true recall and recognition was better for neutral than negative items, and although false recall was also higher for neutral items, false recognition was higher for negative items. The last three experiments examined adults’ (Experiment 3) and children's (Experiments 4 and 5) 1-week long-term recognition of neutral and negative-emotional information. The results replicated the immediate recall and recognition findings from the first two experiments. More important, these experiments showed that although true recognition decreased over the 1-week interval, false recognition of neutral items remained unchanged whereas false recognition of negative-emotional items increased. These findings are discussed in terms of theories of emotion and memory as well as their forensic implications.     

Using stressful films to analyze risk factors for PTSD in analogue experimental studies – which film works best?

Abstract

To understand mental disorders, analogue paradigms provide an indispensable contribution. In posttraumatic stress disorder (PTSD), the stressful film paradigm is a frequently used analogue approach: Films depicting traumatic events are shown to non-clinical participants in order to elicit stress responses analogue to responses to traumatic events in real life. Previous studies used a large variety of films, which is problematic with regard to the comparability of results. The main goal of this study was to identify a film clip that (a) consistently provokes stress reactions and (b) provokes reactions that are as similar as possible to traumatic stress.

We randomly exposed 105 male and female participants to one of four stressful films, differing, e.g., in content and origin. Intrusive memories of the film, reported immediately after the film and during a diary phase of three days, as well as distress, heart rate, and several mood states were measured. A film clip depicting rape elicited the most consistent reactions that were characterized by a higher heart rate, more distress and more intrusive memories, compared to the other three clips. Intrusive memories across all films were especially related to an increase in heart rate and disgust in response to the film.     

Betting on conditionals

A study is reported testing two hypotheses about a close parallel relation between indicative conditionals, if A then B, and conditional bets, I bet you that if A then B. The first is that both the indicative conditional and the conditional bet are related to the conditional probability, P(B|A). The second is that de Finetti's three-valued truth table has psychological reality for both types of conditional—true, false, or void for indicative conditionals and win, lose, or void for conditional bets. The participants were presented with an array of chips in two different colours and two different shapes, and an indicative conditional or a conditional bet about a random chip. They had to make judgements in two conditions: either about the chances of making the indicative conditional true or false or about the chances of winning or losing the conditional bet. The observed distributions of responses in the two conditions were generally related to the conditional probability, supporting the first hypothesis. In addition, a majority of participants in further conditions chose the third option, “void”, when the antecedent of the conditional was false, supporting the second hypothesis.

HeartMath: a positive psychology paradigm for promoting psychophysiological and global coherence

This article proposes HeartMath as a positive psychology paradigm for promoting psychophysiological and global coherence . It provides evidence for the value of psychophysiological and global coherence, with special reference to human functioning through synchronisation between positive emotions, cardiovascular, respiratory, nervous, immune and other physiological systems . Various HeartMath tools and techniques are described and evidence for their effectiveness provided, drawing from several related South African studies . Psychophysiological and global coherence bear promise as fertile fields for future research and intervention of great potential to develop humanity and promote global health and wellbeing.
