fMRI correlates of inhibition of return in perifoveal and peripheral visual field

When a target appears in the same peripheral location as a previous cue, responding is typically delayed if the cue-target interval is relatively long. This phenomenon is termed inhibition of return (IOR) and has been suggested to reflect an attentional bias in favour of novel visual space. It has been demonstrated recently that IOR is much stronger in the far periphery than in the perifoveal visual field. The present study further investigated the neural mechanisms underlying this eccentricity effect of IOR with an event-related fMRI technique. The results demonstrated a stronger activation in visual cortex for perifoveal processing and a broader activation in multiple brain areas for peripheral processing. When IOR effects were compared between these two areas, a stronger activation of the fronto-parietal network was evidenced for perifoveal versus peripheral IOR, while the prefrontal cortex was more strongly involved in the peripheral IOR versus perifoveal IOR. These results suggest that different neural mechanisms are mediating the dissociable inhibitory functions between the perifoveal and peripheral visual field.     

加强我国卫生领域科研诚信建设的重要性

近几年来,我国的科研不端案例呈不断上升趋势.科技部、教育部、中国科学院,国家自然科学基金委员会、中国科学技术协会等部门或机构已发布了关于科研不端行为的处理规定,然而在我国卫生领域科研不端行为的处理和科研诚信建设方面尚未出台相关政策或指导意见.加强我国卫生领域的科研诚信建设具有重要意义.     

审美心理素质教育模式探析

审美心理素质教育定位于受教育者人格的发展：其本质核心是感性的独立;其基本特征是情感的通融;其特殊功能是创造力的释放;其价值定向是生命的体验。本模式通过具体教育内容引发学生预期心理活动,养成相应的审美心理素质：在智育中展开认知活动,获得感性领悟;在德育中激发动机,内化情感体验;在体(劳)育中实践意志品质,感受生命潜能;在美育中获得审美策略,独立创造意象,这些审美心理素质的综合可实现完整人格的塑成。     

特征和结构信息对草图人脸识别的影响

在人脸认知研究的特征说、结构说和整体说的基础上,通过草图人脸与人脸相似程度主观评价的调查,发现五官位置、拓扑结构、五官比例、轮廓外形和五官外形等五个维度对人脸识别影响的权重依次减小,并且存在着多种显著的不同水平的交互作用。进而提出,五官位置和拓扑结构可组合成具体图形意义上的结构关系,这种结构关系将整体人脸分解成有序的特征集。     

Reducing prejudice through priming of control-related words

We investigated the effect of incidentally presented constructs that imply self-control on activated stereotypes associated with immigrants. To activate immigrant stereotypes, participants responded to a scale that measures people's prejudice toward immigrants. They were then primed, using scrambled sentences, with words that were related to self-control (e.g., control, restrain, self-regulate) or with neutral words. After the priming task, participants evaluated an ambiguous behavior of a target person. On the basis of three experiments, the results showed that participants primed with the control-related words rated the target behavior more positively than those primed with neutral words. The results are discussed in relation to previous research on self-control, automatic influence of activated constructs, and prejudice reduction.

论中药品种保护中的法律责任

中药品种保护是不同于专利保护、商标保护的一种新的中药保护模式。它带有浓厚的行政保护色彩。为了更好的保护我国中药知识产权,规范中药的生产和销售行为,应当完善现有的中药品种保护制度,重构中药品种保护中的责任机制,与其他知识产权保护方式相互结合,形成中药知识产权保护体系。     

对手术同意书的法律思考

手术同意书是现代医疗制度中的重要医疗文书.从法律角度看,它具有医务人员职务行为、履行注意义务、履行告知义务及医疗行为合法性等证明效力的法律属性,也具有患者自愿作出选择并授权医方实施手术法律效力,但不具有免除医疗机构责任的效力.由此,需要对手术同意书签字权、内容和形式、手术相关情况的告知过程等加以完善.     

中医药的专利权保护

中医药为中华民族和世界人民的健康做出了重要贡献,但是由于我国对中医药知识产权保护的落后,我国中医药的珍贵知识财富正为外国大公司无偿地攫取.根据中医药自身的特性,对专利保护的适用、调整、改进及补充作了大胆设想,为我国进一步完善中医药的专利法保护提出了建议.
