The number of only children in China has increased rapidly since the late 1970s, when the Chinese government advocated the “one-child-per-family” policy. This increase has caused much public concern about the healthy growth of the young generation. In this study the behavioral traits of Chinese, urban, only children were investigated. The participants were 444 children with siblings and 473 only children from Grades 1, 3, and 5 in Beijing primary schools. An inventory consisting of 27 items covering three behavioral traits was developed. The children were rated on the inventory by the principal teacher of the class. Factor analysis revealed three main factors: achievement motivation, interpersonal skills, and attitude toward manual labor. The only children exceeded the sibling children on achievement motivation. No differences were found between only children and sibling children on interpersonal skills and attitude toward manual labor. Gender differences were evident; girls consistently received higher ratings on achievement motivation and interpersonal skills. The possible underlying reasons for these differences are discussed.     

The Use of Non-invasive Brain Stimulation Techniques to Facilitate Recovery from Post-stroke Aphasia

Aphasia is a common symptom after left hemispheric stroke. Neuroimaging techniques over the last 10–15 years have described two general trends: Patients with small left hemisphere strokes tend to recruit perilesional areas, while patients with large left hemisphere lesions recruit mainly homotopic regions in the right hemisphere. Non-invasive brain stimulation techniques such as transcranial magnetic stimulation (TMS) and transcranial direct current stimulation (tDCS) have been employed to facilitate recovery by stimulating lesional and contralesional regions. The majority of these brain stimulation studies have attempted to block homotopic regions in the right posterior inferior frontal gyrus (IFG) to affect a presumed disinhibited right IFG (triangular portion). Other studies have used anodal or excitatory tDCS to stimulate the contralesional (right) fronto-temporal region or parts of the intact left IFG and perilesional regions to improve speech-motor output. It remains unclear whether the interhemispheric disinhibition model, which is the basis for motor cortex stimulation studies, also applies to the language system. Future studies could address a number of issues, including: the effect of lesion location on current density distribution, timing of the intervention with regard to stroke onset, whether brain stimulation should be combined with behavioral therapy, and whether multiple brain sites should be stimulated. A better understanding of the predictors of recovery from natural outcome studies would also help to inform study design, and the selection of clinically meaningful outcome measures in future studies.     

Shared Knowledge Matters: Culture as Intersubjective Representations

The intersubjective representation approach to culture focuses on cultural members’ shared knowledge representations about the culture that they are in. Members of the same culture tend to share certain knowledge representations of the central characteristics of the culture. These shared cultural representations are established and perpetuated through dynamic communicative processes. Recent empirical research has provided support for the incremental value of intersubjective cultural representations in research on cultural identity, social cognition, and behaviors. The intersubjective representation approach complements extant research on culture as self and external artifacts. In doing so, it allows for a more comprehensive understanding of culture’s role in social and personality psychological processes.     

联想学习对消费行为的影响：基于产品搜索经验的视角

消费者能够基于长期形成的联结产生预期并引导产品搜索。然而,在实际搜索过程中,消费者可能会遭遇符合预期的经验或违反预期的经验。本研究主要探讨基于不同产品搜索经验的联想学习影响消费行为的机制,主要涉及(1)消费者是否会基于产品搜索经验的联想学习产生“违反预期”的预期,并且影响随后搜索中的注意加工;(2)违反预期和符合预期的产品搜索经验对任务无关信息的联想学习所产生的影响,同时关注先前短期的联想学习能否建立预期从而引导随后的产品注意搜索过程;(3)基于产品搜索经验的联想学习对产品偏好的影响,并将行为偏好和大脑奖赏进行联系。本研究有助于阐明消费情境中产品搜索对消费者行为和大脑的影响机制,为营销应用中通过改变消费体验、促进产品购买提供实证依据。     

Shifts of spatial attention in perceived 3-D space.

Previous studies have shown that spatial attention can shift in three-dimensional (3-D) space determined by binocular disparity. Using Posner's precueing paradigm, the current work examined whether attentional selection occurs in perceived 3-D space defined by occlusion. Experiment 1 showed that shifts of spatial attention induced by central cues between two surfaces in the left and right visual fields did not differ between the conditions when the two surfaces were located at the same or different perceptual depth. In contrast, Experiment 2 found that peripheral cues generated a stronger cue validity effect when the two surfaces were perceived at a different rather than at the same perceptual depth. The results suggest that exogenous but not endogenous attention operates in perceived 3-D space.     

兰州市清真寺经堂教育调查研究

兰州是西北经堂教育的重要发展地。调查显示,在经堂学习的人数相当可观。近20年来兰州市清真寺经堂教育经历了传统继承期、改革尝试期、改革认同期三个阶段,现在处于传统与现代之间徘徊的“瓶颈”状态。改革是发展经堂教育的必由之路,改革的关键就是调整教育价值取向,同时,树立正规教育观和教育职业观。     

心理学中对假设检验一些批评的分析

根据假设检验原理的贝叶斯统计的表达方式分析和回应了心理学中对传统的假设检验方法的主要批评.认为:(1)确定假设的接受域不仅要考虑,同时也应该考虑以及这个假设的先验概率,而元分析方法的提出可看作对先验概率考虑的必然的逻辑结果;(2)零假设是可以接受的,但它的接受域只是备掸假设接受域余集的一个子集;(3)传统的假设检验方法需要其他方法的补充.
