Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase. 相似文献

Four studies examined gender differences in self-construals and the role of social comparison in generating these differences. Consistent with previous research, Study 1 (N=461) showed that women define themselves as higher in relational interdependence than men, and men define themselves as higher in independence/agency than women. Study 2 (N=301) showed that within-gender social comparison decreases gender differences in self-construals relative to a control condition, whereas between-genders comparison increases gender differences on both relational interdependence and independence/agency. Studies 3 (N=169) and 4 (N=278) confirmed these findings and showed that changing self-construal changes gender differences in social dominance orientation. Across the 4 studies, strong evidence for the role of in-group stereotyping as mediator of the effect of gender on self-construal was observed on the relational dimension but not on the agentic dimension. 相似文献

Effect of bilateral stimulation of the subthalamic nucleus on parkinsonian dysarthria 总被引:5,自引:0,他引:5
Never was the effect of bilateral stimulation of the subthalamic nucleus (STN) evaluated quantitatively on all the components of speech production, that is articulation, respiration and phonation, at the same time. It is the purpose of this study which uses force measurements of the articulatory organs and acoustic analysis in 16 parkinsonian patients. With STN stimulation, reaction and movement time of the articulatory organs decreased and their maximal strength, as well as their precision increased. We also noted a large beneficial effect on voice with a significant improvement in respiratory and phonatory functions. 相似文献

S. W. Allen and L. R. Brooks (1991) have shown that exemplar memory can affect categorization even when participants are provided with a classification rule. G. Regehr and L. R. Brooks (1993) argued that stimuli must be individuated for such effects to occur. In this study, the authors further analyze the conditions that yield exemplar effects in this rule application paradigm. The results of Experiments 1-3 show that interchangeable attributes, which are not part of the rule, influence categorization only when attention is explicitly drawn on them. Experiment 4 shows that exemplar effects can occur in an incidental learning condition, whether stimulus individuation is preserved or not. The authors conclude that the influence of exemplar learning in rule-driven categorization stems from the attributes specified in the rule or in the instructions, not from the stimulus gestalts. 相似文献

In this study, a personalization method (Guida, Tardieu, & Nicolas, European Journal of Cognitive Psychology, 21: 862–896 2009) was applied to a free-recall task. Fifteen pairs of words, composed of an object and a location, were presented to 93 participants, who had to mentally associate each pair and subsequently recall the objects. A 30-s delay was introduced on half of the trials, the presentation rate was manipulated (5 or 10 s per item), and verbal and visuospatial working memory tests were administered to test for their effects on the serial curve. Two groups were constituted: a personalized group, for whom the locations were well-known places on their university campus, and a nonpersonalized group, for whom the locations did not refer to known places. Since personalization putatively operationalizes long-term working memory (Ericsson & Kintsch, Psychological Review, 102: 211–245 1995)—namely, the capacity to store information reliably and rapidly in long-term memory—and if we take a dual-store approach to memory, the personalization advantage would be expected to be greater for pre-recency than for recency items. Overall, the results were compatible with long-term working memory theory. They contribute to validating the personalization method as a methodology to characterize the contribution of long-term memory storage to performance in working memory tasks. 相似文献

We examined two critiques of rule-assessment methodology: (a) the method does not take into consideration other rules that subjects use to solve problems, and (b) its multiple-choice format misrepresents subjects' cognitive level. In Study 1, high school students completed a paper-and-pencil, multiple-choice balance scale questionnaire. Their performance was assessed with Siegler's original rules and a revised set of rules that included an addition and a qualitative proportionality rule. Results showed that Siegler's Rule 3 was not homogeneous and that distinguishing specific patterns of answers among Rule 3 subjects increased the diagnostic value of the rule-assessment methodology. In Study 2, we compared rule-assessment methodology to the Piagetian clinical model. High school students solved balance-scale problems within each method. Results indicated an overall match between Piagetian levels and Siegler's rules, with the exception of Rule 3, suggesting again the pertinence of specifying alternative rules. 相似文献

Abstract This study investigated the meaning of working for subjects from three levels of an organizational hierarchy. Staff members of a high technology manufacturing organization were surveyed using an abridged version of the Meaning of Working Questionnaire. Five central aspects of the ‘meaning of working’ concept were explored using this instrument, namely Work Centrality, Work Role Identification, Valued Working Outcomes, Societal Norms about Working, and Work Goals. Results show a high level of shared perceptions by members of the three hierarchical levels on ‘meaning of working’ variables, a finding which is at odds with past research, which for the most part indicates clear hierarchal effects. Such findings are discussed within the context of the internal processes of the organization as well as in a specific industry-wide framework. 相似文献

ABSTRACT In cognitive skill learning, shifts to better strategies for obtaining solutions often occur while associations between problems and solutions are being strengthened. In two skill learning experiments, we examined the effects of item difficulty on the retrieval of solutions and the learning of problem–solution associations in younger and older adults. The results of both experiments demonstrated an ‘easy effect’ in both younger and older adults, such that the retrieval of solutions as well recognition memory for problems was best for the easier items. In addition, a ‘hard effect’ was found in younger adults, but not in older adults, whereby the retrieval of solutions as well as recognition memory for problems was better for harder items than for medium-difficulty items. The finding that increased computational demands at the item level delayed item memorization and the retrieval of solutions in older adults but not younger adults is consistent with a general-resources account of age-related differences in skill learning. 相似文献

Previous research that investigated whether biographical information about familiar people is harder to retrieve from voices than from faces produced contrasting results. However, studies that used a strict control of the content of spoken extracts reported that semantic information about familiar people is easier to retrieve when recognising a face than when recognising a voice. In all previous studies faces and voices of famous people were used as stimuli. In the present study, personally familiar people's voices and faces (standard faces and blurred faces) were used. Presenting such people (i.e., participants’ teachers) allowed controlling still more strictly the content of the spoken extracts since it was possible to ask all the target persons to speak the same words. In addition, it was previously stressed that we encounter famous people's faces in the media more frequently than we hear their voice. This methodological difficulty was presumably reduced when teachers’ faces were presented. Present results showed a significant decrease in retrieval of biographical information from familiar voices relative to blurred faces even though the level of overall recognition was similar for blurred faces and voices. The role of the relative distinctiveness of voices and faces is discussed and further investigation is proposed. 相似文献
