异体手移植的临床开展是自体断肢再植技术和免疫学研究发展的结晶,是异体器官移植领域内新的突破,为手缺失患者带来了重新获得新手的希望。但目前异体手移植技术尚不成熟,能否在免疫抑制剂作用下获得长期存活尚不确定。在远期疗效尚未肯定的情况下,建议加强医生自身修养和伦理道德教育,规定由少数具备条件的单位大力开展异体手移植的基础及临床研究,达到既保护患者利益,又能保证异体手移植技术顺利走向成熟,最终广泛应用于临床,造福于人类。  相似文献

儿童计算的元认知监测及其对策略选择的影响   总被引:2,自引:0,他引:2  
吴灵丹  刘电芝 《心理科学》2006,29(2):354-357
为了考察儿童在计算中的元认知监测及其对策略选择的影响,选用两种实验材料,对五种元认知监测判断的特点及监测判断对策略选择的影响进行考察,发现:儿童的元认知监测判断等级值总体上具有较高的一致性,元认知监测判断大多与策略选择高度相关,具有较好的预测力,但受材料、指导语等因素影响,又呈现出复杂的关系。本研究从一个侧面证实了元认知监控的基本假说和元认知监测判断的状态说。  相似文献

The effect of sensory deficits on power grip force from individual phalanges was examined. The authors found that stroke survivors with sensory deficits (determined by the Semmes-Weinstein monofilament test) gripped with phalanx force directed more tangential to the object surface, than those without, although both groups had similar motor deficits (Chedoke-McMaster and Fugl-Meyer), grip strength, and skin friction. Altered grip force direction elevates risk of finger slippage against the object thus grip loss/object dropping, hindering activities of daily living. Altered grip force direction was associated with altered muscle activation patterns. In summary, the motor impairment level alone may not describe hand motor control in detail. Information about sensory deficits helps elucidate patients' hand motor control with functional relevance.  相似文献

In the present investigation longitudinal data obtained from recruits undergoing basic military training in the Swiss Armed Forces were used to examine the effects of organizational citizenship behavior (OCB) on a subsequent cadre selection and the willingness to voluntarily pursue a career as militia cadre. Results of the hierarchical logistic regression controlling for demographic variables, cadre recommendation, and allocation to the desired branch of service showed OCB predicted both the selection as cadre and the voluntariness to pursue a career as militia cadre. These effects show to what extent OCB may predict significant additional effort. Results are discussed with regard to further examination of the effects of OCB on career outcomes and selection decisions.  相似文献

Pain is unpleasant. It is something that one avoids as much as possible. One might then claim that one wants to avoid pain because one cares about one's body. On this view, individuals who do not experience pain as unpleasant and to be avoided, like patients with pain asymbolia, do not care about their body. This conception of pain has been recently defended by Bain [2014 Bain, D. 2014. Pains That Don't Hurt, Australasian Journal of Philosophy 92/2: 30520.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]] and Klein [forthcoming Klein, C. forthcoming. What Pain Asymbolia Really Shows, Mind. [Google Scholar]]. In their view, one needs to care about one's body for pain to have motivational force. But does one need to care about one's body qua one's own? Or does one merely need to care about the body that happens to be one's own? In this paper, I will consider various interpretations of the notion of bodily care, in light of a series of pathological cases in which patients report pain in a body part that they do not experience as their own. These cases are problematic if one adopts a first-personal interpretation of bodily care, according to which pain requires one to care about what is represented as one's own body. The objection can run as follows. If the patients experience the body part as alien, then they should not care about it. Therefore, they should be similar to patients with pain asymbolia. But they are not. Hence, bodily care is not necessary to pain. To resist this conclusion, one can try to revise the interpretation of the notion of bodily care and to offer alternative interpretations that are not first-personal. However, I will show that that those alternatives also fail to account for these borderline cases of pain.  相似文献

The Simon effect, better performance when irrelevant stimulus location corresponds with the response location than when it does not, typically is larger for older than younger adults. However, Simon and Pouraghabagher [Simon, R. J., & Pouraghabagher, A. R. (1978). The effect of aging on the stages of processing in a choice reaction time task. Journal of Gerontology, 33, 553-561] found no age difference using an accessory-stimulus Simon task in which the relevant dimension was the color of a visual stimulus and the irrelevant dimension the location of a tone. Experiment 1 confirmed that older adults show a larger Simon effect than younger adults for the visual Simon task and that this age-related deficit is reduced or eliminated for the auditory-accessory task. Experiment 2 provided evidence suggesting that a small part of the age-related deficit in the visual Simon task is due to having to code the location of the relevant stimulus, but Experiment 3 showed that the majority of the deficit is due to the relevant and irrelevant information being conveyed by the same stimulus. Reaction-time distribution analyses show similar functions for younger and older adults, suggesting that the time course of activation is similar for both age groups.  相似文献

The nonvisual self-touch rubber hand paradigm elicits the compelling illusion that one is touching one’s own hand even though the two hands are not in contact. In four experiments, we investigated spatial limits of distance (15 cm, 30 cm, 45 cm, 60 cm) and alignment (0°, 90° anti-clockwise) on the nonvisual self-touch illusion and the well-known visual rubber hand illusion. Common procedures (synchronous and asynchronous stimulation administered for 60 s with the prosthetic hand at body midline) and common assessment methods were used. Subjective experience of the illusion was assessed by agreement ratings for statements on a questionnaire and time of illusion onset. The nonvisual self-touch illusion was diminished though never abolished by distance and alignment manipulations, whereas the visual rubber hand illusion was more robust against these manipulations. We assessed proprioceptive drift, and implications of a double dissociation between subjective experience of the illusion and proprioceptive drift are discussed.  相似文献

While evolution deserves theological support and inclusion in schools, the consensus views, Darwinian or neo-Darwinian evolution, present problems. Darwin presented two arguments: 1) that evolution, descent with modification, has occurred, and 2) that its “cause” is natural selection, the focus of neo-Darwinism. However, the products of natural selection, adaptations, are often not congruent with the lineages produced by evolution and its demonstrated effects are within species. The difficulty of using natural selection to explain evolution is used by proponents of Intelligent Design (ID) to denigrate evolution and to argue for the inclusion of ID in biology classes. However, the force of the arguments in favor of ID disappear when evolution is viewed as an informational phenomenon. Evolution, like development, is a system of increasing complexity, and emergence the inevitable outcome of the transformation of matter whereby the information in DNA is expressed that accompanies energy dynamics. Evolution is witnessed by studies in comparative biology that reveal groups of related organisms and homologies, both the result of descent with modification.  相似文献
