消极身体意象是青少年健康成长所面临的重要问题之一。了解消极身体意象对青少年的危害以及其形成的影响因素, 对于青少年群体身心健康发展具有重要意义。消极身体意象对青少年的负面影响主要包括自我概念、情绪体验、体重控制策略、饮食失调和社会生活五个方面; 并且青少年消极身体意象形成的影响因素主要有生物因素(BMI)、社会文化因素(父母、同伴和大众媒体)和心理因素(人格因素、认知方式)。未来可从以下几个方面进一步深入研究:(1) 基于生物-心理-社会模型的视角完善青少年身体意象发展的理论模型; (2) 考察社交媒体等新兴因素的作用; (3) 阐明青少年在加工身体相关信息时的认知特点; (4) 推进中国青少年消极身体意象本土化研究。 相似文献

身体自我表征中的身体拥有感(即我的身体属于我的感受)问题一直是自我意识研究的核心话题。大量的已有研究表明, 身体拥有感的体验涉及不同感官信号的整合, 当前大多数研究只重视视觉、触觉等外感受的作用, 一方面忽视了内感受的作用, 另一方面也缺乏对两类感受整合的关注。橡胶手错觉实验和身体障碍患者身上所表现出的外感受和内感受对身体拥有感的影响支持了身体拥有感的可塑性假设, 自由能量原理认为身体拥有感形成的基础是大脑不断评估更新可能性表征来维持稳定。未来的研究需要从改善内感受的测量和刺激呈现方法, 探索影响内感受的高阶认知因素以及关注某些神经症患者的内感受等方面寻求突破。 相似文献

身体表征是一种内部结构,它具有追踪身体状态并对其进行编码的功能。这种结构可以对身体进行错误的表征,并可以从身体中分离出来。来自海豹肢症与躯体失认症等方面的病例,证实部分身体畸形与脑损伤患者的身体表征存在分离;来自橡胶手错觉与全身错觉的实验证据,验证了健康个体身体表征分离的事实。基于上述证据,以身体图式和身体意象为二分维度的模型解释了身体表征的分离。未来的研究可以从神经心理学实验和虚拟现实技术着手,对身体表征的分离进行深入探究。 相似文献

身心关系问题是人类长期探究的重要议题。精神分析学家对身心关系具有诸多独特见解,具体表现为:身体是心理的基础,身体是心理的象征,身体与心理的交织。此三种观点不仅反映出不同精神分析学家在方法论、认识论以及本体论上的差异,也蕴含着精神分析不同流派的理论脉络。厘清精神分析视域下的身心观,既有助于自然科学心理学与人文科学心理学在精神分析中寻求一种主客交织的研究视角,也可为心理学和其他学科领域研究身心关系问题提供新的切入点。 相似文献

为探讨乳腺癌患者反刍这一认知情绪调节方式在体象和创伤后应激障碍(PTSD)、创伤后成长(PTG)之间的中介作用,采用体象量表(BIS)、认知情绪调节问卷中文版(CERQ-C)、创伤后应激障碍量表(PSS)和创伤后成长问卷(PTGI)对150名乳腺癌术后患者进行研究。结果发现:(1)乳腺癌患者的体象可以正向预测PTSD和PTG;(2)乳腺癌患者的反刍在体象和PTSD的闯入性症状、回避性症状中起中介作用,在体象与PTG中的中介作用不显著。结果表明,体象既可以正向预测乳腺癌患者的PTSD和PTG,也可以通过反刍的中介作用影响PTSD。 相似文献

Developing mice were growth-retarded by underfeeding of their mothers during lactation. Control mothers were well nourished throughout. All offspring were fed ad libitum from weaning till their behaviour was tested in adulthood. The undernourished mice had weight deficits at weaning of 49% compared with controls. Nevertheless, they showed partial catch-up growth thereafter, in that their absolute weight deficits decreased between weaning and adulthood. Social behaviour observations were made on pairs of mice of the same treatment group. Previously undernourished mice were slower to start attacking one another, spent more time near or in contact with one another and did less tail-rattling than their controls. 相似文献

Recognizing oneself, easy as it appears to be, seems at least to require awareness of one's body and one's actions. To investigate the contribution of these factors to self-recognition, we presented normal subjects with an image of both their own and the experimenter's hand. The hands could make the same, a different or no movement and could be displayed in various orientations. Subjects had to tell whether the indicated hand was theirs or not. The results showed that a congruence between visual signals and signals indicating the position of the body is one component on which self-recognition is based. Recognition of one's actions is another component. Subjects had most difficulty in recognizing their hand when movements were absent. When the two hands made different movements, subjects relied exclusively on the movement cue and recognition was almost perfect. Our findings are in line with pathological alterations in the sense of body and the sense of action. 相似文献

The interconnection of social theory to social aspects of aging has grown in recent years. The theoretical movement entitled structured dependency, couched in social class analysis, has tended to ignore an understanding of aging identity, the body, cultural representations of aging, and positive images of aging, all of which are central features of an emerging postmodern paradigm in gerontological theory. This article argues that the concept of gender can form a useful bridge, a continuity, between structured dependency and postmodernism in theoretical gerontology. Unfortunately, the compartmentalization of these two conceptual approaches has made their links difficult to forge. This article attempts to take a first step in this direction by highlighting the way postmodern ideas can be used to understand a modernist issue—gender in a gerontological context. Also, focusing on the aging body as a primary form of analysis generates some novel insights into the importance of both the theoretical understanding and cultural representations of the body. 相似文献

For scientific knowledge to be trustworthy, it needs to be dissociated from material interests. Disinterested research also
performs other important non-instrumental roles. In particular, academic science has traditionally provided society with reliable,
imaginative public knowledge and independent, self-critical expertise. But this type of science is not compatible with the
practice of instrumental research, which is typically proprietary, prosaic, pragmatic and partisan. With ever-increasing dependence
on commercial or state funding, all modes of knowledge production are merging into a new, ‘post-academic’ research culture
which is dominated by utilitarian goals. Growing concern about conflicts of interest is thus a symptom of deep-seated malaise
in science and medicine.
An expanded version of this paper was presented at an International Conference on “Conflict of Interest and its Significance
in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002. 相似文献

Technology is believed to have liberated health care from dogmas, myths and speculations of earlier times. However, we are
accused of using technology in an excessive, futile and even detrimental way, as if technology is compelling our actions.
It appears to be like the monster threatening Dr. Frankenstein or like the socerer’s broom in the hand of the apprentice.
That is, the same technology that should liberate us from myths, appears to be mythical. The objective of this article is
to investigate the background for the re-entrance of the myth: How we encounter it and how we can explain it. The main point
is that a myth of technology is normative: it relates ‘is’ and ‘ought’ and directs our actions. This becomes particularly
clear in health care. Hence, if there is a myth of technology, it is an ethical issue, and should be taken seriously. 相似文献
