美容外科的安全性问题与伦理原则   总被引:1,自引:0,他引:1  
围绕美容外科的安全性进行伦理学分析,认为美容外科的有效性与有伤性的不可分是美容外科的基本特征,因此,美容外科实施过程中必须遵循伦理学的有利无伤、知情同意、解释说明的原则,并且要把美容外科的安全性作为首要原则.  相似文献

针对Manens和WolterS(2002)关于内插材料加工对内隐记忆的影响的研究设计中没有考虑到内插材料与目标词语义特征匹配这一条件,通过实验证实了,与目标词有不同特征匹配的内插材料加工对目标词线索提取的内隐记忆有着不同影响:可能没有影响,可能干扰也可能促进。在不同学习加工类型和不同测验类型条件下,内插材料对内隐记忆的影响将可能表现出更加复杂的情况。  相似文献

顿悟式组块破解的时间进程:ERP研究   总被引:4,自引:0,他引:4

本研究旨在探讨顿悟式组块破解的信息加工机制及神经动态变化。被试完成汉字拆解任务,也即从一个源汉字中移动部件从而得到有效汉字。研究操纵部件之间在空间交错背景下的类别关系:同类(移动部件和剩余部件都是汉字)和异类(移动部件是笔画,剩余部件是汉字)。与此同时记录事件相关电位变化。结果显示,同类条件比异类条件引发了更大的N2波动和减小的LPC波动。早期的N2效应可能提示了组块破解过程中的识别困难,而晚期的LPC效应可能提示了组块破解过程中的知觉转换困难。  相似文献

The question of whether humans represent grammatical knowledge as a binary condition on membership in a set of well‐formed sentences, or as a probabilistic property has been the subject of debate among linguists, psychologists, and cognitive scientists for many decades. Acceptability judgments present a serious problem for both classical binary and probabilistic theories of grammaticality. These judgements are gradient in nature, and so cannot be directly accommodated in a binary formal grammar. However, it is also not possible to simply reduce acceptability to probability. The acceptability of a sentence is not the same as the likelihood of its occurrence, which is, in part, determined by factors like sentence length and lexical frequency. In this paper, we present the results of a set of large‐scale experiments using crowd‐sourced acceptability judgments that demonstrate gradience to be a pervasive feature in acceptability judgments. We then show how one can predict acceptability judgments on the basis of probability by augmenting probabilistic language models with an acceptability measure. This is a function that normalizes probability values to eliminate the confounding factors of length and lexical frequency. We describe a sequence of modeling experiments with unsupervised language models drawn from state‐of‐the‐art machine learning methods in natural language processing. Several of these models achieve very encouraging levels of accuracy in the acceptability prediction task, as measured by the correlation between the acceptability measure scores and mean human acceptability values. We consider the relevance of these results to the debate on the nature of grammatical competence, and we argue that they support the view that linguistic knowledge can be intrinsically probabilistic.  相似文献

The development of methods for in vivo detection of cerebral beta amyloid retention and tau accumulation have been increasingly useful in characterizing preclinical Alzheimer’s disease (AD). While the association between these biomarkers and eventual AD has been demonstrated among cognitively intact older adults, the link between biomarkers and neurocognitive ability remains unclear. We conducted a meta-analysis to test the hypothesis that cognitively intact older adults would show statistically discernable differences in neuropsychological performance by amyloid status (amyloid negative = A-, amyloid positive = A+). We secondarily hypothesized a third group characterized by either CSF tau pathology or neurodegeneration, in addition to amyloidosis (A+/N+ or Stage 2), would show lower neuropsychology scores than the amyloid positive group (A+/N- or Stage 1) when compared to the amyloid negative group. Pubmed, PsychINFO, and other sources were searched for relevant articles, yielding 775 total sources. After review for inclusion/exclusion criteria, duplicates, and risk of bias, 61 studies were utilized in the final meta-analysis. Results showed A+ was associated with poorer performance in the domains of global cognitive function, memory, language, visuospatial ability, processing speed, and attention/working memory/executive functions when compared to A-. A+/N+ showed lower performances on memory measures when compared to A+/N- in secondary analyses based on a smaller subset of studies. Results support the notion that neuropsychological measures are sensitive to different stages of preclinical AD among cognitively intact older adults. Further research is needed to determine what constitutes meaningful differences in neuropsychological performance among cognitively intact older adults.  相似文献

This study reported 2 experiments that studied the effect of perspective taking on assessment of creative products by using human raters. Forty responses of 2 alternative uses tasks (AUTs) and 15 alien stories generated by 6th-grade students were used as assessment materials. Undergraduate students as the novice raters assessed the products under 3 experimental conditions: assessing without any information of the ratees, assessing only with age information of the ratees, and assessing with age information and taking the perspective of the ratees. Results of Experiment 1 showed significant differences in creativity ratings between group 1 and 2. But no significant difference was found between group 2 and 3. In Experiment 2, raters in group 1 used objective perception and raters in group 3 were asked to take the perspective for more time. Raters in group 3 assigned higher ratings than the other 2 groups but no difference was found between group 1 and 2. Overall, the results showed the effect of perspective taking on assessment of creative products. Possible mechanisms of the effect and implications for creativity assessment and creativity teaching practice were discussed.  相似文献

Research suggests that negative life events facilitate stress-related growth, such as the development of coping strategies and restoration skills. In this study, we aimed to capture the characteristics of stress-related growth among Korean adolescents who have visual impairments. Using a constructive grounded theory methodology, three themes were identified as characteristics of stress-related growth experiences: (a) developing meaningful relationships, (b) creating coping strategies, and (c) discovering personal strength. This study indicates that Korean adolescents who had visual impairments developed their own coping strategies to deal with various stressors and increased their awareness of their inner strengths and talents. It also suggests that challenging life circumstances may provide opportunities for Korean adolescents who have visual impairments to experience emotional wellbeing.  相似文献
