换脸术几个问题的理性思考 总被引:1,自引:0,他引:1
换脸术是目前国内外争论的一个焦点,是异体器官移植领域内新的突破,为严重毁容患者带来了重新获得美容的希望。但是目前还有很多问题需要进一步。在远期疗效尚未肯定的情况下,作为医务工作者,我们需要加强自身修养和伦理道德教育,做出正确的决定,并不断进行相关研究,最终广泛应用于临床,造福于人类。 相似文献

ABSTRACT— There has been little research over the past few decades focusing on similarities and differences in the form and function of emotional signals in nonhuman primates, or whether these communication systems are homologous with those of humans. This is, in part, due to the fact that detailed and objective measurement tools to answer such questions have not been systematically developed for nonhuman primate research. Despite this, emotion research in humans has benefited for over 30 years from an objective, anatomically based facial-measurement tool: the Facial Action Coding System (FACS). In collaboration with other researchers, we have now developed a similar system for chimpanzees (ChimpFACS) and, in the process, have made exciting new discoveries regarding chimpanzees' perception and categorization of emotional facial expressions and similarities in the facial anatomy of chimpanzees and humans, and we have identified homologous facial movements in the two species. Investigating similarities and differences in primate emotional communication systems is essential if we are to understand unique evolutionary specializations among different species. 相似文献

Two studies investigated the reactions of minority group members to messages about identity expression by ingroup and outgroup sources. Our main hypothesis was that compared to ingroup sources, outgroup sources arouse more anger when they argue for identity suppression. In the first study homosexuals evaluated an outgroup source arguing for identity suppression more negatively than an ingroup source, felt more threatened by this source and as a result, experienced stronger feelings of anger towards this source. The second study among members of a language-based minority replicated and extended these findings. Furthermore we showed that the anger that is experienced towards an outgroup source causes a willingness to change the opinion of this source. When ingroup or outgroup sources supported identity expression, evaluations and experience of anger did not differ in both studies. The importance of a source’s group membership in reactions to opinions about one’s group is discussed. 相似文献

In this study, 104 children completed a task, measuring risk decision-making, and the State-Trait Anger Expression Inventory for Children and Adolescents. Subjects were also asked to evaluate the degree of danger, benefit, fun and fear perceived for each risky choice. Analyses indicated that (a) risk decision-making was predicted by both trait anger and outward expression of anger; (b) appraisal of danger fully mediated the relationship between trait anger and risk; (c) perceptions of benefit, scare and fun partially mediated the relationship between trait anger and risk; and (d) appraisal of danger partially mediated the relationship between outward expression of anger and risk decision-making. The results provide evidence for a relationship between dispositional anger and risk decision-making during childhood, suggesting a possible explanation of the mechanisms below. In particular, risk decision-making can be viewed as the output of cognitive and emotive processes, linked to dispositional anger that leads children to be amused, optimistic and fearless in potentially risky situations. These findings substantiate the importance of incorporating cognitive and emotive factors in theories that seek to explain the relationship between personality traits and risk decision-making across a broad age range. 相似文献

Aggressive responding following benzodiazepine ingestion has been recorded in both experimental and client populations, however, the mechanism responsible for this outcome is unclear. The goal of this study was to identify an affective concomitant linked to diazepam‐induced aggression that might be responsible for this relationship. Thirty males (15 diazepam and 15 placebo) participated in the Taylor Aggression Paradigm while covertly being videotaped. The videotapes were analyzed using the Facial Action Coding System with the goal of identifying facial expression differences between the two groups. Relative to placebo participants, diazepam participants selected significantly higher shock settings for their opponents, consistent with past findings using this paradigm. Diazepam participants also engaged in significantly fewer appeasement expressions (associated with the self‐conscious emotions) during the task, although there were no group differences for other emotion expressions or for movements in general.

Bimodal bilinguals are hearing individuals who know both a signed and a spoken language. Effects of bimodal bilingualism on behavior and brain organization are reviewed, and an fMRI investigation of the recognition of facial expressions by ASL-English bilinguals is reported. The fMRI results reveal separate effects of sign language and spoken language experience on activation patterns within the superior temporal sulcus. In addition, the strong left-lateralized activation for facial expression recognition previously observed for deaf signers was not observed for hearing signers. We conclude that both sign language experience and deafness can affect the neural organization for recognizing facial expressions, and we argue that bimodal bilinguals provide a unique window into the neurocognitive changes that occur with the acquisition of two languages. 相似文献

This paper considers the importance of the body for self-esteem, communication, and emotional expression and experience, through the reflections of those who live with various neurological impairments of movement and sensation; sensory deafferentation, spinal cord injury and Möbius Syndrome (the congenital absence of facial expression). People with severe sensory loss, who require conscious attention and visual feedback for movement, describe the imperative to use the same strategies to reacquire gesture, to appear normal and have embodied expression. Those paralysed after spinal cord injury struggle to have others see them as people rather than as people in wheelchairs and have been active in the disability movement, distinguishing between their medical impairment and the social induced disability others project onto them. Lastly those with Möbius reveal the importance of the face for emotional expression and communication and indeed for emotional experience itself. All these examples explore the crucial role of the body as agent for social and personal expression and self-esteem. 相似文献

Looking at You or Looking Elsewhere: The Influence of Head Orientation on the Signal Value of Emotional Facial Expressions 总被引:1,自引:0,他引:1
The role of horizontal head tilt for the perceptions of emotional facial expressions was examined. For this, a total of 387
participants rated facial expressions of anger, fear, sadness, and happiness, as well as neutral expressions shown by two
men and two women in either a direct or an averted face angle. Decoding accuracy, attributions of dominance and affiliation,
emotional reactions of the perceivers, and the felt desire to approach the expresser were assessed. Head position was found
to strongly influence reactions to anger and fear but less so for other emotions. Direct anger expressions were more accurately
decoded, perceived as less affiliative, and elicited higher levels of anxiousness and repulsion, as well as less desire to
approach than did averted anger expressions. Conversely, for fear expressions averted faces elicited more negative affect
in the perceiver. These findings suggest that horizontal head position is an important cue for the assessment of threat.
