身体拥有感及其可塑性：基于内外感受研究的视角

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。     

身体表征的分离:二分解释模型及其证据

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。     

调节定向视角下在线评论感知有用性的眼动研究

本研究采用2评论类型(属性型VS体验型)×2调节定向(促进VS预防)的眼动实验,深入探讨消费者对在线评论的加工过程和感知有用性的认知机理。研究发现：(1)与属性型评论相比,个体对体验型评论的认知过程更短,感知有用性却更高。(2)相对于预防定向个体而言,促进定向个体对在线评论的认知加工过程更短,感知有用性更高。(3)评论类型和调节定向的交互效用,在属性型评论情境中显著,但在体验型评论情境中不显著。研究结果揭示了评论类型和调节定向影响消费者对在线评论认知评估的作用机理。     

精神分析视域下的身心观

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。     

术后乳腺癌患者体象对创伤后应激障碍和创伤后成长的影响：反刍的中介作用

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。     

Body size as a determinant of aggression during heterosexual encounters in hormone-treated gonadectomized pigs

Aggressive and sexual behavior was studied in 5-minute paired encounters between testosterone-treated castrated boars and estrogen-treated ovariectomized gilts. The boars were either 15 kg heavier (N = 6), or lighter (N = 6), than the gilts (N = 8). Tests were carried out over a 4-week period, during which time each boar was paired once with each gilt; the procedure was replicated over a further 4 weeks. Gilts usually initiated the aggression, especially in the first 4-week period; however, the degree of aggression was positively correlated with body size, irrespective of sex. Aggression was reduced in the second 4-week period in both sexes in tests with large, but not with small, boars. Large boars were more sexually active than small boars, and their sexual performance improved markedly with time, unlike that of the small boars. Champing was positively correlated with aggression duration in pigs of both sexes, and salivation was seen more often in boars than gilts.     

Sense of body and sense of action both contribute to self-recognition

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.     

Postmodernism Versus Modernism: Rethinking Theoretical Tensions in Social Gerontology

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.     

The myth of technology in health care

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.     

Do representations of male muscularity differ in men's and women's magazines?

Men overestimate the degree of muscularity that is attractive to women, and women overestimate the degree of thinness that is most attractive to men. Consistent with the thesis that sociocultural input influences such body type preferences and beliefs, we postulated that magazines aimed at a male audience would portray a more muscular male body ideal than would magazines aimed at a female audience. Systematic comparison of popular magazines (Cosmopolitan, Men's Health, Men's Fitness, and Muscle & Fitness) revealed that the ideal male body marketed to men is more muscular than the ideal male body marketed to women. We introduce the Physical Trait Overvaluation Hypothesis, which proposes that gender-specific media fuel emphasis on certain body parts in within-gender prestige competitions. The resulting competitive escalation creates a disconnect between the preferences of one gender and the personal aspirations of the other.
