汉字属性匹配与大脑两半球协同活动

在识别汉字时,大脑两半球同时加工的作业成绩是否随加工阶段的增加而显出优势。本研究用汉字形、音、义三种属性分别相匹配的方法用用指定指定提取法,所得实验结果一致表明,形似材料双侧视野同时识别与单侧视野识别成绩无显著差别,而同音与近义材料则表现出双侧呈现显著优于单侧呈现的作业成绩。最后结合脑功能成像研究,对加工阶段影脑半球佃同活动的原因进行了讨论。     

Does cardiovascular reactivity during speech reflect self-construction processes?

Abstract

Substantial empirical research has been undertaken on cardiovascular reactivity (CVR). however interpretation of this research is hampered by a lack of theoretical frameworks. This paper develops a framework initially stimulated by evidence demonstrating that the cardiovascular system increases in activity during communication, and that the extent of this activation depends upon numerous and diverse psychosocial factors. We attempt to account for this phenomenon using merit post-structuralist ideas concerning the constructive nature of language and its centrality to an individual's sense of self. Our theoretical framework proposes that the CVR exhibited during language use is explicable in terms of self-construction - From this analysis we hypothesised that CVR would differ across conversations about private self. public self and non-self topics, and that these differences would depend upon people's speaking histories. We found that the blood pressure and heart rate of 102 women was most reactive when they talked in a laboratory with a stranger about aspects of their private self, and least reactive during non-self talk, whilst their heart rate was most reactive during talk about their public self. Overall the results highlight the inextricable link between our inherent socialness and our cardiovascular systems.

SUMMARY

The explanatory scheme outlined here is an attempt to provide a social reconceptualisation of a phenomenon that is typically interpreted in individualistic psychophysiological terms, and which is consistent with the notion that repeated exposure to situations which provoke large haemodynamic changes may lead to CHD disease progression. The explanation draws heavily on post-structuralist ideas regarding language, and the social constructionist notion that engaging in language use is central to constructing and maintaining a sense of self. This sense of self is a central theoretical entity in our everyday lives, produced and maintained in our interactions with others. We argue that it is this centrality of self-construction that helps to explain the extraordinary consistency of elevated CVR in conversation. Further, we have noted the striking parallels between those features of conversations that make the self salient, and those that have been associated with elevated CVR. To examine it more explicitly, it needs to be tested empirically with new data, using explicitly derived operationalisations and hypotheses.     

Evaluating the method of levels

An investigation of the method of levels (MOL) was undertaken. Based on the principles of perceptual control theory (PCT), MOL is a way of helping people to reduce psychological distress. MOL assumes that psychological distress results when people are unable to control experiences that are important to them. The approach was implemented over six months in a large urban GP practice. Patients attended for between one and six sessions. Patients who attended for more than one session demonstrated significant reductions in scores of symptomatology on a standardized questionnaire. Effect sizes of these differences were relatively large. There appeared to be no relationship between the number of sessions a patient attended and the amount of reduction in symptomatology that was recorded. Similarly, there was no relationship between the number of sessions a patient attended and their recorded level of symptomatology at their first appointment. Although the study has important limitations we suggest that these findings might offer new directions for future research and might provide a way of unifying the specific and common factors as well as understanding the Dodo Bird effect.     

空间推理的脑机制：一项ERP研究

记录14名正常成人完成四种空间推理及一种基线任务（记忆任务）时的事件相关电位,对空间推理的脑电活动情况进行考察。研究结果表明,在200ms-900ms窗口,推理任务比基线任务诱发更大的正成分。对不同推理任务的比较表明,具体与抽象材料的单模型推理诱发相似的波形;单模型与有效的双模型任务诱发的ERP成分明显不同,在300ms-600ms窗口,后者比前者诱发更大的正波;在200-600ms时间窗口,存在有效结论与无有效结论的双模型问题也诱发明显不同的ERP波形。研究的结果表明,推理与记忆涉及不同的加工要求,推理需要整合前提的信息,而记忆只需要储存前提信息。在解决双模型推理问题时,从200ms开始,被试就对刺激材料进行初步的加工与判断,随后对双模型问题采用有注解的单模型加工策略。另外,不同材料的空间推理任务之间的波形较为一致,表明视觉表象并未明显影响空间推理过程。

禀赋效应的心理机制及其影响因素

禀赋效应是指个体在拥有某物品时对该物品的估价高于没有拥有该物品时的估价的现象。这一现象在行为经济学中普遍存在。禀赋效应的研究范式包括经典研究范式与物物交换范式。禀赋效应的心理机制主要包括损失规避与查询理论。禀赋效应的影响因素主要包括认知角度、动机、情绪、交易物品的特征、研究设计的选择等。未来的研究需要从禀赋效应的适用条件、产生根源、研究范式的改进等方面进一步探讨。
