心率变异性在心身疾病和情绪障碍研究中的应用   总被引:6,自引:0,他引:6  
心率变异性的频谱成分可单独反映交感神经和副交感神经活动的影响。高频(HF)是由迷走神经单独介导;低频(LF)受迷走神经和交感神经共同调制,但主要反映交感神经的活动性 。此指标可对高血压、冠心病和月经前期烦躁等心身障碍进行评价。该文还探讨了它用于情绪研究的价值,并认为在不同情绪体验期间的自主神经活动有多种搭配模式,正常人与情绪障碍者之间以及情绪障碍(抑郁、焦虑、恐怖、强迫)患者在自主神经活动方面可能存在显著差别  相似文献

国内首次302m氦氧饱和潜水模拟实验中,用心理学测验和主观感觉询问对3名受试者的神经和心理反应现象进行了观察。加压到200m、250m、302m和302m停留1天后,受试者的简单视觉运动反应时较常压对照值分别延长了7.3%、4.5%、6.5%和6.1%。加压到200m受试者书面心理学测验失分率较常压对照值增加了156.4%。加压到250m受试者滚珠投递数和失误数较常压对照值分别减少12.2%和增加27.6%。302m停留1天后受试者滚珠投递数和失误数较常压对照值分别减少11.3%和增加56.2%,扑克花样分类时间较常压对照值增加8.7%,书面心理学测验失分率较常压对照值增加113.8%。减压后或减压毕,上述各指标的变化均恢复常压对照水平。根据测试结果和受试者的症状和体征,实验中所观察到的高压神经综合症的表现较国外同样深度的实验报道为轻,这可能与实验采用的缓慢加压速度和设置中间驻留站有关。  相似文献

观察表明,群体隔离(10—12周)的大白鼠,在开阔地方的自由活动和杀小鼠行为方面没受到明显影响,但隔离鼠在电击后格斗行为明显地增加了。隔离鼠脑内单胺类种经介质的含量无明显改变。在电击格斗后群居组和隔离组脑内DA含量均明显降低。群居组鼠端脑内NE含量增高,脑干内5-HIAA含量降低,但隔离组无上述改变。隔离鼠在注利血平、电击后格斗行为明显减少。对上述现象进行了讨论。  相似文献

本文对31名听力正常的健康人作了脑干听觉电反应(BSR)描记。21人在记录过程中让其心算乘法,其中16人还令其注意听刺激短声并概算其触发次数。观察到21名心算者的BSR中16人的BSRⅠ波振幅比安静时的减小,20人的BSR出现了一阳性大波,未观察到Ⅰ波振幅增大的。在听短声的16人中未见出现Ⅰ波振幅减小者,且其中4人反而出现了Ⅰ波振幅相对增大,结果表明,心算乘法对BSR有一定影响,分析认为一种是对感受器的负反馈控制,另一种是正反馈控制,而且前者占优势。  相似文献

精神健康复元运动发轫于20世纪90年代的美国,强调以人为中心、由服务使用者驱动、以优势为基础,是形塑21世纪全球精神卫生政策的重要力量。通过对美国精神健康复元运动的系统爬梳,探诘其三大主要的社会历史脉络,即美国对严重精神障碍痊愈的认识转变、美国精神病学消费者运动的变迁、美国社会心理康复领域的发展,强调为推动国内精神卫生体系超越生物医学模式并实现以复元为导向的范式转移,需要持续改革的精神、精神障碍亲历者的参与、精神健康社会工作与临床心理学的人才建设以及更多有关复元的本土化研究。

The Chinese translation of the Wechsler Intelligence Scale for Children--Revised (WISC-RC) was administered to 660 children (ages 6 through 16 yr.) in the city of Shanghai. The obtained norms represent children's intelligence levels in big cities where the economic and cultural development is advanced. The norms are reported as "Scaled Score Equivalents of Raw Scores" for each age group and as "IQ Equivalents of Sums of Scaled Scores." The reliability and validity of the norms indicate that the WISC-R is suitable for use with school-age children in China. The difference between the results for our Shanghai sample (WISC-RCs) and a USA sample (WISC-R) is also discussed.  相似文献

Socioeconomic status (SES) is a complex phenomenon that is predicted by a broad spectrum of variables and is often conceptualized as a combination of financial, occupational, and educational influences. SES is associated with symptoms of depression and depression-related personality traits. Many studies have focused on the relationship between SES and depression symptoms in clinical subjects; however, there are few studies of the neural basis of the relationship between SES and depression-related personality traits in nonclinical subjects. Thus, in the present study, we studied the neural basis of the relationship between SES and depression-related traits. The first step was to use voxel-based morphometry (VBM) to investigate the neuroanatomical basis underlying family SES in a large sample of healthy subjects. We found a significant negative correlation between family SES and the medial prefrontal cortex (mPFC) that extending to the anterior cingulate cortex (ACC). Then, the mediation analysis revealed that the correlation between family SES, especially family income, and depression-related traits were mediated by the region of the mPFC that extending to the ACC volume. These findings suggest that the family income may play more important role in driving depression-related traits than that of parental education. They also suggest that the mPFC extension to the ACC may play an important role in the correlation between familial SES, especially with respect to family income and the depression-related traits.  相似文献

Patterns of agreement between parent and child ratings of psychosocial functioning and fatigue in children with obesity were examined. Analyses demonstrated moderate agreement for social anxiety in elementary children and small agreement for social anxiety in adolescents. Results of analyses of overall quality of life revealed small agreement in children under the age of 8, large agreement in children ages 8–12, and moderate agreement in adolescents ages 13–18. Overall ratings of fatigue demonstrated moderate agreement both in elementary children and in adolescents. A meaningful relationship was found between each factor measured by a parent and a child. Patterns which were unexpected given the existing literature were found; possible hypotheses explaining these patterns are presented; and the need for further research is highlighted.  相似文献

The extent to which younger and older adolescents differed in their value judgments of historically important events was examined. Subjects were asked to list the ten most important events that happened in or to the U.S. since 1990. The subjects' choices were analyzed as a function of sex, age, political and religious orientation, and family size. In addition, 100 undergraduates were asked to serve as judges and predict which categories would be cited more frequently by males and which by females. Results indicated that the judges' predictions did not match the data. Age was a much better predictor of value judgments than sex. Further, several additional differences in value judgments were revealed that would have been missed had only the variables of sex and age been included in the analyses.  相似文献

在马克思的历史唯物主义理论中,生产关系无疑是一个极其重要的概念。但如果对这一概念在马克思哲学发展的不同时期所具有的不同内涵缺乏一个准确的把握,那就不容易对马克思历史唯物主义  相似文献
