镜像神经系统—研究药物依赖行为的新靶点

镜像神经是近年来认知与大脑神经科学研究中崭新的课题,大量实验证实了镜像神经元(系统)参与到了多种心理能力的发展与进化之中。目前有研究发现,吸烟相关线索会激活尼古丁成瘾者大脑相应的动作脑区,而该区域也正是人类镜像神经区域,这意味着镜像神经在相关线索激发的心理渴求中可能扮演了重要角色。该实验结果有重要的意义,动作计划脑区的神经线索反应为发展可靠的依赖行为的生物学标记提供了另一个新目标,不仅开发了一个新型的依赖行为的理论模型,还为把神经科学的研究发现运用到实践应用打下了良好的基础。     

不同指导语对成本-收益结构条件推理的影响

该研究以社会契约问题为研究材料,对217名在校大学生进行了调查研究,旨在考查不同指导语对成本-收益结构条件推理作业成绩的影响,结果表明:(1)社会契约主效应显著,标准社会契约作业成绩好于转换社会契约;(2)不同指导语的主效应显著,证伪指导语更易于激活"辨别欺骗者程序";(3)成本-收益结构条件推理任务能有效激活"辨别欺骗者程序",以找出潜在的欺骗者。     

Working memory modulates the perception of time

Recent research has indicated that reentrant feedback from the contents of working memory can enhance neural representations and the perceptual strengths of matching stimuli in the visual field. However, whether the contents of working memory can also distort conscious experiences of perception remains unclear. Our present results show that the durations of perceptual stimuli matching the nontemporal representations in working memory tend to be perceived as longer than those of mismatching stimuli. This is the first demonstration that working memory can lead to distortions of time perception. Our findings are consistent with the ideas that the perceived duration of a stimulus depends on the magnitude of the neural responses to that stimulus in visual cortex and that there is a common system for representing both temporal and nontemporal magnitudes. We conclude that top-down modulation from the nontemporal contents of working memory distorts the perceptual experience of temporal duration.     

Social presence and service satisfaction: The moderating role of cultural value‐orientation

Two studies examine the role of the cultural value orientation, self‐construal, as a moderator of the relationship between social presence and service satisfaction. Cross‐cultural data are collected in China and the USA to maximize variation on self‐construal. Results suggest that social presence effects vary depending on the consumer's independent self‐construal. Regardless of whether the service encounter is positive or negative, social presence increases the strength of satisfaction or dissatisfaction for low independents but not for high independents.

Spatial orienting in the visual field: a unified perceptual space?

Visual attention can be oriented toward a spatial location in the visual field exogenously by an abrupt onset of a peripheral cue. In a series of behavioral studies on exogenous orienting of attention with a double-cue paradigm, we demonstrated a functional subdivision of perceptual space in the visual field. Specifically, inhibition of return (IOR) is much stronger at periphery relative to perifoveal visual field up to approximately 15° eccentricity, suggesting two dissociable functional areas in the visual field. To further investigate the generality of this functional subdivision of the visual field, we measured IOR effects with another single-cue paradigm and applied a very short cue-target interval that was typically anticipated not to observe any inhibitory effect at all. Consistent with this expectation, no IOR effects at the eccentricities up to 15° were observed. However, significant IOR effects beyond 15° eccentricities were consistently demonstrated. These results not only revealed an early onset of IOR for more peripheral stimuli, but also confirmed that the perceptual space in the visual field is not homogeneous but underlies a functional subdivision with a border of ca. 15° eccentricity.     

移植物抗宿主病与移植物抗肿瘤的处置

移植物抗宿主病与移植物抗肿瘤是当前异基因造血干细胞移植中一对不可调和的矛盾。在解决这一矛盾方面,科学家们已取得了很大的进展。随着移植学、免疫学的发展和认识的深入,最终能够最大限度的削弱移植物抗宿主病,增强移植物抗肿瘤效应,提高移植后患者的生存质量。

功能性内窥镜鼻窦外科应用的情况及问题

20世纪70年代,以慢性鼻窦炎/鼻息肉为主要治疗对象的功能性内窥镜鼻窦外科的创立和发展,开辟了鼻窦外科的新领域.功能性内窥镜鼻窦外科技术把鼻窦外科推向了新的阶段,使鼻窦炎临床治愈率提高到80%～90%,已成为国内外鼻窦炎外科治疗的主要方式.回顾功能性内窥镜鼻窦外科的发展历史,分析了鼻腔-鼻窦病变中应用的情况,并提出了应用中应处理好的两个问题,对准确把握功能性内窥镜鼻窦外科发展的趋势和特点具有重要的作用.     

训诂、解释与文化传承

从中国文化发展的历史看,“训诂”被看做后人继承前人文化的一个重要途径。由于历代统治者出于自身需要而提供大力支持,“训诂学”在中国文化史上成为一门重要的学科之一,尽管近代以后由于新文化运动的兴起而日渐衰落。在西方思想史上,解释学也是一门具有悠久传统的学科,早在中世纪就有了关于圣经典籍的解释学,到了近代有施莱尔马赫和狄尔泰的解释学,到了现代又有伽达默尔的哲学解释学。我们今天把训诂学与解释学放到一起讨论,很大程度上是因为哲学解释学的深刻影响,促使我们对自己文化解释的反思。我们首先必须清楚地认识到,训诂与解释有着…
