Children worldwide experience mental and emotional disorders. Mental disorders occurring among young children, especially infants (birth –3 years), often go unrecognized. Prevalence rates are difficult to determine because of lack of awareness and difficulty assessing and diagnosing young children. Existing data, however, suggest that rates of disorders in young children are comparable to those of older children and adolescents (von Klitzing, Dohnert, Kroll, & Grube, 2015 ). The lack of widespread recognition of disorders of infancy is particularly concerning due to the unique positioning of infancy as foundational in the developmental process. Both the brain and behavior are in vulnerable states of development across the first 3 years of life, with potential for enduring deviations to occur in response to early trauma and deprivation. Intervention approaches for young children require sensitivity to their developmental needs within their families. The primacy of infancy as a time of unique foundational risks for disorder, the impact of trauma and violence on young children's development, the impact of family disruption on children's attachment, and existing literature on prevalence rates of early disorders are discussed. Finally, global priorities for addressing these disorders of infancy are highlighted to support prevention and intervention actions that may alleviate suffering among our youngest world citizens.  相似文献

研究为探索常驻高海拔地区军人心理健康水平如何随社会年代变迁而改变,运用了横断历史元分析的方法,对1993年至2013年38篇采用90项症状自评量表(SCL-90)的文献调查数据进行分析,考察了11454名常驻高海拔地区军人在该量表上9个因子得分随年代变化的趋势.结果发现:(1)SCL-90的7个因子均值与年代负相关,且不受期刊类型等的影响.20年来,7个因子下降了5%~15%不等.其中,强迫变化最大,抑郁、焦虑、人际敏感、偏执和精神病性均变化明显.这说明,常驻高海拔地区军人心理健康虽有所波动但整体水平逐步提升,变化幅度大致属于中等程度.(2)当年军费占GDP比值、居民消费水平指数与SCL-90部分因子均值负相关显著;5年前的居民消费水平指数与7个因子显著负相关.这说明,国防建设的经济投入和居民消费水平可能是影响常驻高海拔地区军人心理健康水平的重要因素.  相似文献

领导-部属交换(LMX)的回顾与展望   总被引:8,自引:0,他引:8  
领导-部属交换理论从领导和部属的对偶关系中考察领导行为及其对下属的绩效、组织承诺等结果变量的影响。文章回顾了领导-部属交换的文献,对于它的概念、理论基础、结构、测量工具等进行了综合介绍,对不同测量工具的各自的特点以及它们之间的关系做了分析,接着总结了影响领导-部属关系的影响因素和结果变量以及与变革型领导的关系,最后提出未来研究应该加强从领导部属交换的发展阶段以及从部属或领导的角度来分析领导-部属交换理论  相似文献

以元认知和双系统模式的心理学理论为背景, 研究了分析式系统对来源国效应的削弱, 检验了产品信息呈现方式对来源国效应的调节作用。三个研究说明, 分析式系统的启动可以有效削弱来源国效应; 特定的产品信息呈现方式所引起的消费者信息处理不流畅性感知会激发消费者的元认知困难, 从而使他们在产品评价过程中主要依赖分析式系统, 达到削弱来源国效应的目的; 并不是所有能引起信息处理不流畅性的产品信息呈现方式都能削弱来源国效应, 过于复杂的呈现方式由于给消费者带来过多认知负荷, 反而不能成功启动分析系统, 从而无法削弱产品来源国形象对消费者产品评价的影响。  相似文献

为探讨自1999年高校国家助学贷款政策出台以来,我国贫困大学生心理健康状况的变迁,本研究对106篇1998至2015年间采用SCL-90量表的研究进行了横断历史元分析,考察了贫困大学生心理健康状况随年代的变化趋势。结果表明:(1)SCL-90量表中9个因子的分数均值均与年代呈负相关,年代对各因子变异的解释在4%至16%之间;1998年到2015年这18年来,各因子均值平均下降范围(效果量d)在0.24至0.55个标准差之间,其中强迫、抑郁和精神病3个因子均值变化尤为明显。这表明贫困大学生整体心理健康的状况在缓慢提升。(2)与中部地区相比,东部和西部地区贫困大学生心理健康水平18年来提高更明显。(3)虽然不同性别贫困大学生各因子历年变化差异并不明显,但女生抑郁和精神病两方面改善略快。此外,普通元分析结果表明总体上贫困男大学生比女大学生心理健康状况要好。  相似文献

考察成人在错误信念(FB)任务上是否存在"知识偏差"效应。实验1重复Birch等的实验程序并未得到与之一致的结果,成人在FB任务上的表现不理想,且无"知识偏差"效应存在。实验2排除琴盒位置及颜色的突出性影响后,结果与实验1相似。成人在FB任务上的不佳表现与成人具有心理理论的事实相悖,说明把通过FB任务作为衡量心理理论的唯一评定标准有待商榷。  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
