背景性质对7-10岁自闭症谱系障碍儿童面孔搜索与加工的作用

为了考察背景性质对ASD者搜索面孔的影响,设计两个眼动实验任务,要求14名7~10岁ASD儿童和20名同年龄正常儿童观看图片。实验一采用将面孔嵌入风景图片中引起语义不一致的刺激;实验二采用含有面孔的无意义背景乱序图片刺激。结果发现：（1）面孔与背景语义不一致并不能促进ASD儿童对面孔的搜索;（2）乱序背景对ASD儿童面孔搜索与加工没有产生干扰作用,但使正常儿童的搜索时间变长;（3）一旦觉察到面孔后,ASD儿童对面孔的注视时间少于正常儿童。表明正常儿童对面孔的搜索与加工受背景性质的影响,而ASD儿童不受背景性质的影响;一旦发现面孔,ASD儿童的注意维持较短,但面孔加工模式与正常儿童相似。

Shear band evolution during large plastic deformation of brittle and ductile metallic glasses

Four monolithic metallic glasses (MMGs) with different plasticities varying from brittle to ductile behavior under unconstrained loading were subjected to small punch testing. All specimens undergo large plastic deformation with multiple cobweb-like shear bands under these conditions. The process of shear band evolution was carefully controlled and investigated. Plasticity of MMGs is characterized by equivalent plastic strain ε* (product of shear band density and critical shear offset). Thus, this article provides an experimental basis for a better understanding of the shear band evolution during plastic deformation of MMGs.     

非哺乳期乳腺炎的现代研究进展

非哺乳期乳腺炎也被称为慢性乳腺炎,是以乳腺内或乳管内残留炎性结节或肿块形成为主要临床表现的一种乳腺迁延性炎症.由于其临床表现缺乏特异性,常易漏诊、误诊,且须与乳腺癌尤其是炎性乳癌相鉴别.B超、钼靶、MRI等是重要的辅助检查方法,但病理检查是诊断和鉴别诊断乳腺疾病的金标准.目前,该病的治疗是以手术为主的包括中西医结合在内的综合治疗.一旦发现乳腺炎性改变,就应考虑到炎性疾病可能,并及早获得病理学的诊断.     

A Model of Chinese Adolescents' Creative Personality

Since the 1950s, there has been a systemic development of research on creative personality. Three themes are apparent in this literature: individual differences of creative people, the construct of creative personality, and longitudinal studies about creative personality. However, little research has been conducted in any of these areas with Chinese samples, and the purpose of this study is to study the construct of Chinese adolescents' creative personality. Confirmatory factor analyses were conducted with data from 1,300 Chinese adolescents. The results provide evidence that adolescents' creative personality consists of three largely independent dimensions: Internal, External, and Self. The internal factor includes self-confidence, norm-doubt, internal motivation, and persistence; the external factor includes curiosity, risk-taking, openness and independence; the self factor pertains to self-acceptance.     

Right Hemispheric Dominance of Creative Insight: An Event-Related Potential Study

The purpose of this study was to investigate the hemispheric effect of creative insight. This study used high-density ERPs to record participants' brain activity while they performed an insight task. Results showed that both insight solutions and incomprehension solutions elicited a more negative ERP deflection (N320～550) than noninsight solutions in the time window of 320～550 msec. Scalp ERPs and topographical maps revealed that the insight N320～550 exhibited a relative RH dominance, whereas the incomprehension N320～550 exhibited a relative midline dominance. Dipole source analysis showed that the generator of N320～550 elicited by insight and incomprehension solutions was localized in the right middle frontal gyrus and the right parahippocampus gyrus, respectively. These distinct spatiotemporal patterns involved in insight processing and incomprehension processing suggest that the observed N320～550 might reflect the processing of set-shift and the formation of novel associations. Moreover, the spatiotemporal pattern of brain activation associated with insight solutions supported the idea that the right hemispheric dominance theory of creative thinking also applies to creative insight.     

Quantile Mediation Models: A Comparison of Methods for Assessing Mediation Across the Outcome Distribution

Recent introduction of quantile regression methods to analysis of epidemiologic data suggests that traditional mean regression approaches may not suffice for some health outcomes such as Body Mass Index (BMI). In the same vein, the traditional mean-based approach to mediation modeling may not be sufficient to capture the potentially different mediating effects of behavioral interventions across the outcome distribution. By combining methods for estimating conditional quantiles with traditional mediation modeling techniques, mediation effects can be estimated for any quantile of the outcome distribution (so-called quantile mediation effects). Estimation and inference techniques for quantile mediation effects are compared through simulation studies, and recommendations are given. The quantile mediation methods are further compared with the traditional mean-based regression approaches to mediation analysis through analysis of data from Healthy Places, a trial that is examining the effects of the community–built environment on resident obesity risk. We found the magnitudes of indirect (mediating) effects of walkability on BMI and waist circumference were substantially larger for the upper quantiles compared with the median or mean. Results suggest that restricting the examination of mediation to the mean of the outcome distribution provides an incomplete picture of proposed mediating mechanisms and in some cases may miss important mediational relationships to outcomes.     

Gender Differences in Reasons for Entering and Leaving Education Administration: Discriminant Function Analyses

Using discriminant function analyses on survey data collected from 457 students in 29 education administration programs across the United States, the authors inquired into whether men and women decide to enter and possibly leave education administration for different reasons. There were statistically significant functions separating men and women in their reasons for entering and leaving education administration. Implications of the findings are discussed.

猜谜作业中的ERP效应：基于催化范式的证据

运用ERP技术对个体猜谜任务下的顿悟和无顿悟的情况进行探索。结果发现,在300ms-500ms内,有顿悟比无顿悟引发了更负的N300-500成分,激活了大部分脑区;在600ms-1100ms内,有顿悟比无顿悟引发了更正的P600-1100成分,在中央区显示了最强激活。结果表明,N300-500可能反映了定势破除中的认知冲突,P600-1100可能反映了新异联系的形成。
