肺血栓栓塞症是常见的临床病症,因其临床表现多样,易发生误诊漏诊而导致较高的病死率.但"凡事顸则立,不顸则废",充分掌握肺血栓栓塞症的知识、以正确的思维方式引导临床诊疗可以有效减少和避免误诊漏诊.     

跨职能知识共享对团队创新绩效的影响机制探索

以扎根理论的研究方法,从知识有效共享的角度分析了跨职能整合对团队创新绩效的影响。结果证明：（1）成员之间的知识共享是实现跨职能整合和提高产品创新绩效的关键机制;（2）知识共享行为受到创新氛围、共同目标和组织支持的共同影响;（3）认知障碍是观点冲突产生的主要原因,而知识共享有助于冲突的解决。在此基础上,本研究对比了不同管理措施对团队创新绩效的作用,为组织管理实践提供了借鉴。     

Forbidding Science: Some Beginning Reflections

Growing powers to manipulate human bodies and minds, not merely to heal disease but to satisfy desires, control deviant behavior, and to change human nature, make urgent questions of whether and how to regulate their use, not merely to assure safety and efficacy but also to safeguard our humanity. Oversight in democratic societies rightly belongs to the polity, not merely to self-appointed experts, scientific or ethical. Yet the task of governing the uses of dangerous knowledge is daunting, and there is little evidence that we have the will or the wisdom to do it well.

ACACIA: an agent-based program for simulating behavior to reach long-term goals

We present ACACIA, an agent-based program implemented in Java StarLogo 2.0 that simulates a two-dimensional microworld populated by agents, obstacles and goals. Our program simulates how agents can reach long-term goals by following sensorial-motor couplings (SMCs) that control how the agents interact with their environment and other agents through a process of local categorization. Thus, while acting in accordance with this set of SMCs, the agents reach their goals through the emergence of global behaviors. This agent-based simulation program would allow us to understand some psychological processes such as planning behavior from the point of view that the complexity of these processes is the result of agent–environment interaction.     

归纳推理多样性效应的发展及其争论

归纳推理多样性效应指的是在归纳论断中,前提项目数量越多、越多样,将能构成归纳力度越强的推理。已有研究表明成人的归纳推理明显受到前提项目多样性的影响,而幼儿的相关研究却存在着两种对立的观点：一是认为幼儿不能基于多样性进行推理,二是认为5岁左右的幼儿就能够基于多样性进行推理。出现此争论的原因可能与研究方法方面的差异有关,如实验范式与前提组间差异、实验材料类别与概念范畴、属性特征及呈现方式、推理形式;此外,儿童的知识经验也是一个影响因素。未来研究可以结合相关领域的研究范式;深入挖掘影响儿童表现出多样性效应的因素;将任务设计多样化;将实验任务的计分方式多样化;开展相关的应用研究。     

动画教学代理对多媒体学习的影响:学习者经验与偏好的调节作用

以往研究发现,动画教学代理对多媒体学习效果的影响不一致,可能受到学习者特征和偏好的调节。本研究以“空调的组成部分及工作原理”为实验材料,采用两个实验控制教学代理有无、经验高低和代理偏好,探讨动画教学代理对多媒体学习的影响。实验1发现与无代理组相比,代理组对教学视频的注视点个数更多,平均眼跳潜伏期更短,学习兴趣也更高;低经验者在代理条件下的迁移成绩更好。实验2发现学习者在偏好代理和非偏好代理条件下的迁移成绩好于无代理组;偏好代理组感知到更低的认知负荷,对总体视频的注视点个数和注视频率更多,平均眼跳潜伏期更短,对学习内容的注视点个数更多。结论认为：在多媒体中加入教学代理不会减少学习者对学习内容的注意,能提高多媒体学习效果,支持社会代理理论假设;教学代理能提高低经验者的学习效果,但对高知识经验者无明显作用;加入学习者偏好的代理形象会促进学习,但加入学习者非偏好的代理形象并没有阻碍学习。     

动画速度和学习者经验对多媒体学习的影响

以往研究显示,动画教学的效果很可能受到学习者先前知识经验与动画速度的影响。研究选取高经验和低经验的学习者,操纵动画播放速度为快、中和慢三个水平,利用眼动仪记录学习过程中的注意,探讨学习者经验和动画速度对学习效果和注意分配的影响。结果发现,在即时测验上,学习者经验和动画速度没有交互作用;在延迟测验上,低经验者在快速下成绩优于中速;高经验者对图片注视时间长于低经验者。研究认为,在即时测验上,学习者的经验水平不会影响动画速度的教学效果;在延迟测验上,低经验者在快速呈现动画时学习效果更好,学习者经验和动画速度对学习效果的影响更可能随着时间推移体现出来;基于整体型学习材料,高经验者比低经验者更关注图片。     

Emotion knowledge,emotion regulation,and psychosocial adjustment in children with nonverbal learning disabilities

Nonverbal learning disability is a childhood disorder with basic neuropsychological deficits in visuospatial processing and psychomotor coordination, and secondary impairments in academic and social-emotional functioning. This study examines emotion recognition, understanding, and regulation in a clinic-referred group of young children with nonverbal learning disabilities (NLD). These processes have been shown to be related to social competence and psychological adjustment in typically developing (TD) children. Psychosocial adjustment and social skills are also examined for this young group, and for a clinic-referred group of older children with NLD. The young children with NLD scored lower than the TD comparison group on tasks assessing recognition of happy and sad facial expressions and tasks assessing understanding of how emotions work. Children with NLD were also rated as having less adaptive regulation of their emotions. For both young and older children with NLD, internalizing and externalizing problem scales were rated higher than for the TD comparison groups, and the means of the internalizing, attention, and social problem scales were found to fall within clinically concerning ranges. Measures of attention and nonverbal intelligence did not account for the relationship between NLD and Social Problems. Social skills and NLD membership share mostly overlapping variance in accounting for internalizing problems across the sample. The results are discussed within a framework wherein social cognitive deficits, including emotion processes, have a negative impact on social competence, leading to clinically concerning levels of depression and withdrawal in this population.     

Googled assertion

Recent work in the philosophy of mind and cognitive science can help to explain why certain kinds of assertions—made on the basis of information stored in our gadgets rather than in biological memory—are properly criticizable in light of misleading implicatures, while others are not.     

知识划界、追赶焦虑与中国本土心理学的理论建构导向

科学心理学以方法为中心的知识建构策略,内在地要求它与常识心理学划界以谋求自然科学分支的学科地位,其代价是对人类心理之情感与意义维度的隔离。在移植西方心理学体系的过程中,科学心理学的争议也内含于中国心理学的发展轨迹中,同时还附加了学术边陲地区特有的学科追赶焦虑。中国本土心理学理论应突破科学至上的观念束缚,致力于发展具有现实解释力和价值引导力的人文主义导向的心理学理论,以切实解决中国现实社会中的心理问题,并在世界心理学界发出真正的中国声音。
