本文从情绪的效价载荷及其脑功能成像研究、面部表情的识别及其脑功能成像研究以及情绪的诱发及其脑功能成像研究等三方面介绍了情绪加工的脑机制及其研究现状。从现有的研究成果来看,大脑皮层在加工不同效价载荷的情绪时具有很大的重叠性;有关面部表情识别的研究表明,不同的神经环路负责调节对不同面部表情的反应;有关诱发的情绪的研究表明,前扣带回皮层在表征实验诱发的情绪时扮演着一个非常重要的角色。文章最后指出了情绪研究目前面临的一些问题,并指出在我国开展情绪的脑机制研究的重要意义。 相似文献

身体锻炼对情绪调节的影响机制述评 总被引:14,自引:1,他引:14
自20世纪60~70年代以来,身体锻炼与心理健康的关系问题,引起了西方心理学界的极大关注,身体锻炼与情绪变化的实证研究越来越多,许多国内、外的研究支持了身体锻炼对调节消极的情绪(如抑郁、焦虑等),改善心境状态有着明显的效果。美国学者Cox(1994)等人在前人研究的基础上归纳总结,提出了身体锻炼对情绪调节的基本假说,即认知行为假说、社会交互作用假说、注意力转移假说、心血管功能假说、内啡肽假说、胺假说。试图从理论上解释身体锻炼对情绪调节的机制。从情绪心理学的角度看,这些假说大抵存在生物观、认知观和社会文化观等三种理论倾向。 相似文献

行为抑制是一种重要的执行功能。考察情绪影响行为抑制的脑机制, 将有助于理解个体如何适应环境, 特别是如何在情绪情境中控制自己的行为。近年来, 研究者开始使用脑成像技术考察情绪影响行为抑制的脑机制。研究发现, 在情绪影响行为抑制的过程中不仅涉及前额叶抑制控制系统和边缘结构情绪加工系统, 而且涉及这两个系统的相互作用, 即情绪加工与行为抑制加工的整合。腹外侧前额皮层、背外侧前额皮层、前扣带回、杏仁核、脑岛等脑区在情绪加工与行为抑制加工的整合中起着重要的作用, 但情绪整合到行为抑制加工中的时间进程还不清楚。今后的研究应着眼于情绪影响行为抑制的时间进程、神经网络、个体差异的影响以及改进研究范式等方向。 相似文献

运用情绪生理学的方法,以31名具有身体攻击行为的初中工读学生和30名普通初中生为研究对象,研究了身体攻击行为学生与普通学生在基线生理唤醒和情绪生理唤醒的方面不同特点。结果发现,在生理唤醒的基线水平上,身体攻击行为学生与普通学生在指温、R-R间期、心率、指脉率方面差异显著,身体攻击行为学生的指温、心率、指脉率比普通学生低,身体攻击行为学生的R-R间期比普通学生R-R间期长。在愤怒刺激条件下,身体攻击行为学生报告的愤怒体验水平比普通学生高;愤怒诱发刺激引起身体攻击行为学生R-R间期、心率变化显著,而普通学生R-R间期、心率变化不显著。厌恶与恐惧、悲伤、愉快诱发刺激引起普通学生皮肤电变化显著,而身体攻击行为学生皮肤电变化不显著 相似文献

情绪活动对免疫系统的影响 总被引:1,自引:0,他引:1
医学心理学新近研究表明,情绪状态及其所伴随的生理反应直接影响免疫系统的功能,积极情绪状态会增强免疫功能,而消极情绪状态则削弱免疫功能,且会提高人对疾病的易感性;情绪调节方式与免疫系统功能间存在着明显相关:积极的情绪调节有助于免疫功能的增强,而消极的情绪调节则导致免疫功能的减弱;情绪宣泄能够缓解创伤或压力事件对免疫功能的消极影响,而抑制消极体验则会导致免疫系统功能的降低,引发更为严重的身心健康问题。 相似文献

在情绪标注的研究中,存在着情绪标注是增强还是抑制负性情绪以及非情绪标注能否抑制负性情绪的争论。研究选择负性情绪面孔和图片为实验材料,以女大学生为被试,采用了16导生理记录仪记录其完成任务时皮电、指温和指脉率上的变化。实验1以负性情绪面孔为材料,采用经典范式试图验证以往研究结果。实验2采用负性情绪图片为材料,探讨了情绪标注和非情绪标注对负性情绪的抑制作用。结果发现:(1)在情绪标注条件下被试的指脉率比情绪匹配条件下的更低;性别标注(即非情绪标注)条件下被试的指脉率与性别匹配条件下的差异不显著;(2)在情绪标注条件下被试的指温比自然或人工标注条件(即非情绪标注)下的更高。研究结果表明,情绪标注可以抑制负性情绪,而非情绪标注则不能抑制负性情绪。 相似文献

1概述人们每天都会加工大量信息,其中许多是第一次接触到的,我们称之为新异信息,而新异联系属于新异信息的一种。在实验研究中,被试所学的项目都是熟悉的,但它们之间的关系需要在学习中形成,被试须加工这种关系,从而将以前互不相关的项目作为一个整体。我们称这种... 相似文献

Research has shown peer victimization to have strong lasting effects on adolescents’ mental health. The purpose of this study was to examine relationships among religiousness, forgiveness, and mental health in the context of peer victimization. We hypothesized that religiousness and forgiveness could be protective factors against negative effects of peer victimization on internalizing symptomatology and emotion regulation. Participants were 127 adolescents between 12 and 18 years old and their primary caregivers. Results of structural equation modeling analyses show that religiousness might not be a strong protective factor in the context of peer victimization and that certain dimensions of forgiveness (specifically benevolence motivations) might actually exacerbate the effects of peer victimization on internalizing symptomatology rather than acting as a protective factor. 相似文献

The rates of onset for several forms of psychopathology peak during adolescence, which coincides with the refinement of brain circuitry attuned to expanding social-contextual interactions, stressors, and settings. Although some adolescents experience mental health difficulties, most do not develop significant problems. Conceptual work suggests that brain-based individual differences in adolescents’ neurobiological susceptibility to their social contexts play a role in the development of psychopathology and well-being. In this article, I summarize evidence supporting the idea that individual differences in brain structure and function moderate the relation between adolescents’ social-contextual experiences and psychopathology. I discuss why this approach is important in developmental research designed to identify adolescents at greatest risk for psychopathology or poised for positive outcomes, as well as those who may benefit most from intervention. 相似文献

The authors examined 3 motives and 3 techniques for forgiveness to assess differences between people high or low in dispositional forgiveness (HDF and LDF, respectively). HDF participants rated all motives as more compelling and familiar than did LDF participants. Forgiveness being the right thing to do was rated as more persuasive and familiar; however, mental and physical health benefits were rated as compelling but less familiar forgiveness motives. LDF participants rated the various techniques as less familiar and more difficult compared with HDF participants. Overall, participants rated forgive and forget as the most familiar but most difficult technique to implement. 相似文献

Activity during unemployment and mental health 总被引:2,自引:0,他引:2
KJELL UNDERLID 《Scandinavian journal of psychology》1996,37(3):269-281
The main purpose of this study was to investigate activity during unemployment and the relationship between such activity and mental health in a sample ( n = 213) of unemployed Norwegians. The results indicate that the unemployed are generally more passive than the average population, and that they are considerably less involved in social activities. However, the unemployed do not constitute a homogenous group in terms of activity level and activity profile. Women were somewhat more active that men, particularly in connection with domestic chores. Young people were more active than the other age groups, particularly in connection with extra-familial activities. Several significant relationships were found between different activity categories and mental health. The more active the unemployed were, the better their mental health. The results are discussed in relation to similar data for the average population, other unemployment research, subjective and objective factors which can be of importance to the activity level and profile of the unemployed, sex role issues, theoretical models developed to explain and understand the effects of unemployment, methodological considerations, and the possible functions of activity for mental health. 相似文献

This article presents three studies which demonstrate that (1) Older women enjoy the status of grandparenthood, and they show resources, continued personal growth, and positive functioning; (2) Spouses provide emotional support, and widowhood has an impact on the experience of emotional loneliness; and (3) As they age, men remain cognitively more preserved, and women affectively more preserved. Over a 3-year period, older people showed smooth changes in physical health, cognitive functioning, and mental health. Results are discussed in terms of healthy living, resilience, positive affect, and also conditions that promote undesirable pathways in older age. Implications for feminist therapy with older people are discussed. 相似文献
