“镜像”的内涵与外延:围绕镜像神经元的争议

镜像神经元被认为是改变认知神经科学的重要发现,它的发现为迄今为止许多行为实验难以检验的心智或认知现象提供了一个统一的研究视角。然而,镜像神经元在社会认知活动中的重要作用却引起了研究者的激烈争论。系统回顾镜像神经元研究中的争议,可以尝试以争论焦点出现的逻辑关系和性质为依据将其划分为两类:一类是关于镜像"内涵"的争议,主要包括镜像神经元是否存在及其起源的争议。另一类则主要围绕镜像"外延"的争议,即有关镜像神经元系统和镜像机制的争议。未来的研究必须摒弃将镜像神经元视为"认知科学圣杯"的神经还原主义倾向,将之视为一个由多个子系统组成的开放的复杂巨系统,并将焦点转向关注镜像机制。     

暴力犯攻击行为与焦虑的关系:CU特质的调节作用

采用冲动性/预谋性攻击量表、冷酷无情特质量表和特质焦虑量表,以山东省某中型监狱341名成人暴力犯为被试考察两类攻击、CU特质水平和特质焦虑之间的关系。结果表明:(1)CU特质水平与两类攻击正相关,与特质焦虑呈负相关,特质焦虑水平能够预测成人暴力犯的冲动性攻击。(2)个体的CU特质水平能够调节特质焦虑与冲动性攻击之间的关系,具体表现为特质焦虑水平对低CU特质个体的冲动性攻击影响大于高CU特质个体。     

An Analysis of Student Privacy Rights in the Use of Plagiarism Detection Systems

Plagiarism detection services are a powerful tool to help encourage academic integrity. Adoption of these services has proven to be controversial due to ethical concerns about students’ rights. Central to these concerns is the fact that most such systems make permanent archives of student work to be re-used in plagiarism detection. This computerization and automation of plagiarism detection is changing the relationships of trust and responsibility between students, educators, educational institutions, and private corporations. Educators must respect student privacy rights when implementing such systems. Student work is personal information, not the property of the educator or institution. The student has the right to be fully informed about how plagiarism detection works, and the fact that their work will be permanently archived as a result. Furthermore, plagiarism detection should not be used if the permanent archiving of a student’s work may expose him or her to future harm.

What to Say to an Online Support‐Seeker? The Influence of Others' Responses and Support‐Seekers' Replies

Research on online support forums has largely overlooked the quality of support provision. The present experiment examined how others' responses and a support-seeker's reply can influence action‐focused supportiveness, emotion‐focused supportiveness, and politeness of readers' support messages. Results showed that the supportiveness of others' comments was associated with subsequent readers' perceptions of public opinion toward the support‐seeker and readers' liking of the support‐seeker, which in turn influenced the quality of readers' support messages.

从西地那非的研发过程探讨医学研究的规律

西地那非研制成功20余年,用于治疗男性勃起功能障碍（erectile disorder,ED）。而近几年来,越来越多的证据表明西地那非可以明显降低各种原因所导致的肺动脉高压（pulmonary arterial hypertension,PAH）。西地那非对肺动脉高压的治疗作用,再次引起了人们对西地那非进行深入研究的兴趣。西地那非的研究历程给人们带来很多有益的启示。     

老年高血压降压不易达标及降压质量低的原因分析及对策

老年高血压降压不易达标或降压质量低,原因在于老年高血压的特殊性,如多发收缩期高血压、血压波动大、易发生体位性低血压、合并多脏器功能损害等。在老年高血压的治疗中,应充分认识其特殊性,开展健康教育、改善生活方式,正确选择降压药,在降压达标治疗的基础上,提高降压质量,最大限度降低患者靶器官损害,减少心血管终点事件的发生。
