采用简化版儿童赌博任务,其中操纵了奖励和惩罚的强度,探察两种亚型(注意缺陷型和混合型)ADHD儿童的情感决策能力,同时采集儿童在任务中的皮肤电活动以探析ADHD儿童在情感决策中的生理机制。结果发现,在不同的奖惩强度下,ADHD儿童情感决策模式不同,在即刻奖励条件下,ADHD儿童情感决策的能力明显弱于正常对照组儿童,倾向于不利选择,所产生的预测性皮电振幅也明显低于正常对照组;在即刻惩罚条件下,ADHD儿童的情感决策能力未见异常。两种亚型ADHD儿童的表现模式相似。上述结果证明,ADHD儿童仅存在对奖励的异常敏感性,并确实影响了其决策能力,而其回避惩罚的能力正常。两种亚型ADHD儿童存在的问题相似 相似文献

自我超越生命意义对压力和健康关系的调节作用 总被引:19,自引:0,他引:19
研究目的是检验一个新的应激应对资源—自我超越生命意义的健康调节作用。自我超越生命意义的理论基础是东方的佛教哲学和道家哲学。研究的测量工具有:大学校园压力量表,一般健康问卷(GHQ-20),自尊量表和自我超越生命意义量表。被试为来自北京市三所高校的788名大学生。研究结果为:自我超越生命意义可以调节应激条件下的忧郁情绪、一般健康问题和自尊,但是对于焦虑情绪和自我肯定的调节作用不明显。研究结论是:自我超越生命意义对心理健康的某些方面具有调节作用 相似文献

汉字属性匹配与大脑两半球协同活动 总被引:7,自引:0,他引:7
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。 相似文献

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. 相似文献

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. 相似文献

对动态范式中基于客体的返回抑制进行了考察。实验1在双侧客体改变和不改变条件下考察了返回抑制效应,结果表明,在双侧客体改变条件下返回抑制仍然存在。实验2采用单侧客体变化技术对动态范式中基于客体的返回抑制进行了测量,结果发现,在有效线索化条件下,单侧客体改变和不改变条件下对靶子的反应时没有显著差异(p > 0.90)。这些结果表明动态范式中基于客体的返回抑制的机制是空间抑制的动态更新,而不是客体表征受到抑制 相似文献
