Balance,Proprioception, and Gross Motor Development of Chinese Children Aged 3 to 6 Years

The authors' aim was to find the features of balance, proprioception, and gross motor development of Chinese children 3–6 years old and their correlations, provide theoretical support for promoting children's motor development, and enrich the world theoretical system of motor development. This study used a Tekscan foot pressure measurement instrument (Tekscan, Inc., Boston, MA), walking on a balance beam, Xsens 3-dimensional positional measuring system (Xsens Technologies, Enschede, the Netherlands), and Test of Gross Motor Development-2 to assess static balance, dynamic balance, knee proprioception, and levels of gross motor development (GMD) of 3- to 6-year-old children (n = 60) in Beijing. The results are as follows: children had significant age differences in static balance, dynamic balance, proprioception, and levels of GMD; children had significant gender differences in static balance, proprioception, and levels of GMD; children's static balance, dynamic balance, and proprioception had a very significant positive correlation with GMD (p < .01), but no significant correlation with body mass index.     

Linking Individual Value Orientations to Employee Attitudes: An Exploratory Analysis

This study tested the relationships of individualism, power distance, and mastery orientation to 2 employee attitudes (organizational trust and organizational commitment) that are associated with employees’ psychological benefits within the organization. Results from university employees (N = 706) showed that individualism negatively, whereas mastery positively, related to trust and commitment. Power distance positively related to trust only. The moderating role of mastery was also identified. These findings can help employment or organizational counselors to appreciate value‐related factors that facilitate employees in psychologically integrating into the organization and to explore new ways for employers to foster employees’ positive attitudes.     

Direct Gaze Blurs Self-Other Boundaries

Self-other merging can arise not only between acquainted people but also between strangers. To date, the factors determining self-other merging between strangers remain to be elucidated. We investigate whether strangers’ facial appearance (i.e. gaze direction) modulates such initial processes of self-other merging. In the two experiments, participants viewed strangers’ faces whose gaze either directed to or averted from them. The extent of self-other merging was measured in terms of perception of face resemblance, Inclusion of the Other in the Self (IOS) scale, and correlations of personality judgments. We found that direct gaze blurred the self-other boundaries at both facial and conceptual levels. Participants felt a stranger who directly gazed at them to be closer and more similar to themselves about face and personality.     

家庭支持与朋友支持对不同自理能力老年人抑郁水平的影响

探讨社会支持中的家庭支持和朋友支持对不同自理能力老年人抑郁水平的影响作用。结果发现:(1)社会支持可有效缓解老年人抑郁症状;(2)对个体而言,家庭支持是较稳定的支持来源,受个体年龄和健康水平的影响较小,而朋友支持变动较大,随年龄增长和健康水平的下降,朋友支持逐渐减少;(3)社会支持对不可完全自理老年人抑郁水平的解释率高于对可完全自理老年人抑郁水平的解释率;(4)对于生活可完全自理的老人,朋友支持比家庭支持有更大的预测作用,而对于生活不能完全自理的老人,家庭支持的作用更大。     

人脑加工自我参照任务的时空特点:来自ERP的证据

以自我参照加工任务为范式,实验采用事件相关电位(ERP)技术,探讨了自我参照加工中符合判断和不符合判断加工的时间进程和大脑神经机制。结果发现,自我参照加工在时间上可以概括分为三个阶段:注意分配阶段N1(80~150 ms)波幅出现自我参照结果的差异;语义整合阶段N2(250~450 ms)波幅和潜伏期出现自我参照结果的差异;评价判断阶段P3(450~700 ms)波幅和潜伏期出现自我参照结果的差异。从我们选择的大脑兴趣区激活水平上分析发现,自我信息在大脑中的激活似乎是一个由右及左,由后及前再及后的动态变化过程。研究结果丰富了自我参照加工的已有结果,并且对未来研究具有一定的启示意义。     

High-magnetic-field-induced formation of aligned equiaxed grains during directional solidification

The application of a high magnetic field is capable of inducing the formation of aligned equiaxed grains in alloys during directional solidification. The alignment and refinement of the grains is enhanced as the magnetic field intensity increases. The thermoelectric power difference at the liquid/solid interface in four alloys has been measured in situ during directional solidification and it is concluded that the formation of aligned equiaxed grains in a magnetic field should be attributed to the combined action of a thermoelectric magnetic force and a magnetization force.     

《雁荡山志》载散佚佛教文献辑考

<正>自佛教传入中土以来,便与中国既有文化开启了富于特色的交融历程。这种交融既表现在内容上,也表现在形式上。在形式上的表现之一,乃是佛教文献与具有中国特色的文献载体的融合,例如具有中国韵文特质的偈语、碑刻、佛教序跋等。这些文献既记录了佛教思想、佛教发展流传史,又具有一定的文学、文献价值。但这种文献类型往往不为文学研究者重视,在编辑断代性文学总集时,也往往未收碑志、铭刻、摩崖等相关内容。对这些佚文进行研究,既可以补充文学总集,扩充作者序列和诗文篇目,又可以为佛教研究提供新的史料。笔者平     

Motion tracking modulates capacity allocation of visual working memory

Previous studies on visual working memory (VWM) have primarily investigated memory for an array presented for a single moment. Here, we examined VWM for two arrays separated by a 1,100-msec interval. We focused on the allocation of VWM capacity to the two arrays as a function of dynamic events inserted between them. During the interval, irrelevant dots moved to form three types of motion: (1) coherent (apparent) motion that connected Arrays 1 and 2, (2) jumpy motion, or (3) coherent motion with two disconnected segments. Results showed that VWM for Array 2’s locations was better than for Array 1’s, especially when the arrays were connected by coherent motion. We suggest that coherent motion between two temporally disparate arrays connects the arrays into a single visual event VWM is then biased toward remembering the more recent state of the event.     

Cognitive disruption and altered hippocampus synaptic function in Reelin haploinsufficient mice

The heterozygote reeler mouse (HRM) shows many neuroanatomical and biochemical features that are also present in some human cognitive disorders, such as schizophrenia. In the present study, hippocampal dependent plasticity and cognitive function of the HRM were characterized in detail in an attempt to reveal phenotypic functional differences that result from Reelin haploinsufficiency. The HRM and wild type mice show similar levels of overall activity, coordination, thermal nociception, startle responses, and anxiety-like behavior. In addition, both genotypes show similar shock threshold, identical cued freezing behavior and comparable spatial learning in Morris water maze tasks. However, a significant reduction in contextual fear conditioned learning was observed in the HRM. Electrophysiological studies in hippocampal CA1 synapses revealed a plethora of differences between genotypes. The HRM exhibits reduced field excitatory postsynaptic potentials in responses to similar synaptic inputs, lowered paired pulse facilitation ratio and impaired long-term depression and tetanus-induced long-term potentiation (LTP). Also, deficits were detected in LTP elicited by theta burst stimulation or by a whole cell pairing protocol. These physiologic differences could not be accounted for by changes in the overall amount of glutamate receptor subunits. In addition, it was determined that network-driven excitatory and inhibitory activities recorded in CA1 pyramidal neurons showed that the HRM had comparable amplitude and frequency of spontaneous excitatory postsynaptic currents, but a marked reduction in spontaneous inhibitory postsynaptic currents. Thus, the HRM exhibits a specific hippocampal-dependent learning deficit accompanied with a pronounced impairment of hippocampal plasticity and functional inhibitory innervation.
