汉语声调远距离规则的内隐学习及其迁移效应

内隐学习研究领域的一个重要问题是内隐学习获得的知识究竟是什么,即内隐学习获得的知识究竟是底层的抽象规则还是表面的特征.研究以汉语声调的远距离水平映射这一远距离规则为材料,通过对表面特征和底层规则之间的分离操作,在控制组块和重复结构等表面特征的条件下,探讨声调远距离规则的习得和迁移,结果发现被试能够内隐地习得和迁移汉语平仄声调的水平映射规则,证实了内隐学习确实能够获得底层的抽象规则,为内隐学习的抽象性问题提供了新的证据.     

Finite Mixtures for Simultaneously Modeling Differential Effects and Nonnormal Distributions

Regression mixture models have been increasingly applied in the social and behavioral sciences as a method for identifying differential effects of predictors on outcomes. Although the typical specification of this approach is sensitive to violations of distributional assumptions, alternative methods for capturing the number of differential effects have been shown to be robust. Yet, there is still a need to better describe differential effects that exist when using regression mixture models. This study tests a new approach that uses sets of classes (called differential effects sets) to simultaneously model differential effects and account for nonnormal error distributions. Monte Carlo simulations are used to examine the performance of the approach. The number of classes needed to represent departures from normality is shown to be dependent on the degree of skew. The use of differential effects sets reduced bias in parameter estimates. Applied analyses demonstrated the implementation of the approach for describing differential effects of parental health problems on adolescent body mass index using differential effects sets approach. Findings support the usefulness of the approach, which overcomes the limitations of previous approaches for handling nonnormal errors.     

早期子宫颈癌根治性子宫颈切除术的临床应用

近年来子宫颈癌发病率呈现上升及年轻化趋势,年轻宫颈癌患者需要保留生育功能。随着新术式和腹腔镜的发展,子宫颈根治性切除术作为治疗早期宫颈癌的一种新的治疗方法,严格掌握其手术实施的适应证,结合医学伦理学和循证医学的原则,既达到了根治性的目的,又充分考虑到生育功能的保留。因此子宫颈根治性切除术是一种可行、有效、合理的手术方式。     

现代技术与奢侈关系的伦理反思

现代技术的发展带来了奢侈消费重心的转移、奢侈消费权利的再分配和奢侈消费观念的变革,影响着大众的消费伦理意识.应当从技术创新角度审视现代技术与奢侈的关系,辩证地看待奢侈品的生产与消费;同时,要防止消费行为脱离伦理规约,避免奢侈消费带来社会分配的不公正和对自然环境的损害.     

Misorientation characteristics of penetrating morphologies at the growth front of abnormally growing grains in aluminum alloy

The initial stage of abnormal grain growth of the aluminum alloy 5052 has been investigated using electron back-scattered diffraction to analyze the characteristic of misorientations of the penetrating morphology at the growth front. Among the 84 penetrating morphologies examined, none of the penetrated grain boundaries has low angles or coincidence site lattice (CSL) relations, whereas 66 penetrating grain boundaries have low angles or CSL relations. These results strongly suggest that the penetrating morphologies should result from triple-junction wetting.     

全身炎症反应综合征治疗新策略——胆碱能抗炎通路

全身炎症反应综合征(systemic inflammatory response syndrome,SIRS)是各种原因刺激机体产生失控的全身性炎症反应的统称,严重者可致多器官功能障碍综合征。迷走神经及其递质乙酰胆碱所构成的胆碱能抗炎通路可以有效抑制局部和全身炎症反应。本文将从胆碱能抗炎通路的作用特点分析激活胆碱能抗炎通路对全身炎症反应综合征的潜在治疗前景。     

Intransigent vowel-consonant position in Korean dysgraphia: evidence of spatial-constructive representation

Dysgraphia due to a focal brain lesion can be characterized by substitution, transposition, deletion and/or addition errors of graphemes or strokes. However, those linguistic errors can be language-specific because the writing system of a given language may influence error patterns. We investigated a Korean stroke patient, a 57-year-old English teacher with dysgraphia both in Korean Han-geul [see text] and in English alphabet writings. The results of an experimental testing revealed transposition errors between a consonant and a vowel only in English but not in Korean writings. This austerity of vowel-consonant position may be attributed to a unique Korean writing system of a spatially well-formed syllabic configuration or block with consonant(s) and a vowel. In light of a neuropsychological model of writing, which depicts a multi-level spelling and writing process, we suggest a spatial-constructional component of internal orthographic representations in Korean writing. This Korean graphemic configuration feature may be resistant to a focal, left cerebral damage, and thus, we also discuss our results in terms of cerebral lateralization of the writing processes.     

Moral in whose eyes? Cross-cultural differences in moral decision making and behaviour

All people want to feel that they are morally adequate. People tend to evaluate their moral adequacy by judging their behaviour through their own eyes (first-person perspective) or the eyes of others (third-person perspective). People in all cultures use both perspectives, but there may be cultural variations in which perspective takes precedence. By conducting two studies, we explore the way people in face cultures are more likely to secure their moral self-regard through the eyes of others (vs. their own eyes), whereas the opposite is true in case of people from dignity cultures. Study 1 found that people from face culture (Korean participants) cheated to a lesser extent when others were invoked (vs. not invoked), but people from dignity culture (American participants) were not affected by this priming. Study 2 found that moral intentions were more strongly influenced by what participants perceived others to do in moral situations in face (vs. dignity) cultures. In contrast, moral intentions were found to be more strongly influenced by what they believed they should do in moral situations in dignity (vs. face) cultures.     

真实场景搜索中的眼动返回抑制

眼动返回抑制是指眼睛返回至先前注视过的位置(客体)时眼跳潜伏期长、可能性低的一种抑制现象。近年来, 研究者对真实场景搜索中的眼动返回抑制进行了深入的研究。本文介绍了相关研究的经典实验范式、主要发现及其理论解释, 探讨了眼动返回抑制的容量、眼动返回抑制是否具有任务特异性、场景搜索中是否存在眼动返回促进以及眼动返回抑制的神经基础等问题, 并指出未来该领域研究的方向和途径。
