An empirical and computational investigation of perceiving and remembering event temporal relations

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.     

Altering element interactivity and variability in example-practice sequences to enhance learning to write Chinese characters

The isolated elements and variability effects of cognitive load theory were used to alter the element interactivity of Chinese characters when instructing novice learners (72 overseas students at a Chinese university) in writing characters using worked examples-practice procedures. A group of characters with more than eight strokes was disassembled into three individual components. Students were required to trace examples and practice writing of either similar sequences of isolated components followed by integrated components of full characters (Isolated–Integrated sequences); variable sequences of isolated followed by integrated components (Variability–Integrated sequences); or conventional Integrated–Integrated sequences of full characters. It was hypothesized that the fully integrated stroke-movements form of example-practice sequences would result in less learning due to a greater cognitive load. The results demonstrated that the participants in both the Isolated–Integrated and Variable–Integrated groups performed significantly better than the Integrated–Integrated group with the Variable–Integrated group outperforming the Isolated–Integrated group.     

道德信息对面孔吸引力判断的无意识调节

抽象语言信息是否能够影响知觉?本研究在审美领域对此进行考察,探索无意识获取的道德信息是否影响个体对相应面孔吸引力的知觉判断。结果发现个体对面孔吸引力的知觉判断受到内隐道德信息的调节,且调节效应与面孔本身吸引力水平无关; 另外,面孔审美判断的反应时受到道德美丑和面孔吸引力的共同影响,尤其当两类信息相矛盾时被试需要更长的时间进行判断。研究结果表明抽象的社会道德信息可以对面孔吸引力的知觉判断产生自上而下的调节。     

Creation and Implementation of an Environmental Scan to Assess Cancer Genetics Services at Three Oncology Care Settings

An environmental scan (ES) is an efficient mixed-methods approach to collect and interpret relevant data for strategic planning and project design. To date, the ES has not been used nor evaluated in the clinical cancer genetics setting. We created and implemented an ES to inform the design of a quality improvement (QI) project to increase the rates of adherence to national guidelines for cancer genetic counseling and genetic testing at three unique oncology care settings (OCS). The ES collected qualitative and quantitative data from reviews of internal processes, past QI efforts, the literature, and each OCS. The ES used a data collection form and semi-structured interviews to aid in data collection. The ES was completed within 6 months, and sufficient data were captured to identify opportunities and threats to the QI project’s success, as well as potential barriers to, and facilitators of guideline-based cancer genetics services at each OCS. Previously unreported barriers were identified, including inefficient genetic counseling appointment scheduling processes and the inability to track referrals, genetics appointments, and genetic test results within electronic medical record systems. The ES was a valuable process for QI project planning at three OCS and may be used to evaluate genetics services in other settings.     

论内化于行动的观念

观念是在先于主客二分的实践(行动主义)视角下、内化于个体活动中的意识,它首先与个体活动相关,有别于仅仅在认识论视角(非时间性的上帝视角)下的意识。作为常识理性的观念、作为社会意识的观念、作为默会知识的观念、作为人的活动形式的"观念的东西"、作为赋予意义和价值评价的观念、作为"思想具体"的观念,是"观念"的六种常见用法。     

公共卫生监测中的伦理原则及标准

从理论上概述了各时期监测定义的演变以及相关伦理辩论,列举了公共卫生监测所引发的普遍的伦理问题及适用的主要伦理原则,揭示了临床医学和公共卫生中伦理问题的不同。人权是个人利益和集体利益的共同基础,因此,也可能是临床伦理和公共卫生伦理的共同基础。最后,依据《世界卫生组织关于公共卫生监测中伦理问题的指南》及其他文献列出多种公共卫生伦理标准,试图在实际工作中帮助评估公共卫生监测方案在伦理上的可接受性。     

急诊护理人员遭受医院场所暴力探讨

音乐训练促进诗句韵律整合加工的神经过程

本研究采用ERP技术,考察音乐训练组和对照组完成诗句押韵判断任务时,在绝句末对韵律信息(含声调和韵母两个维度)的整合加工过程。结果发现,在100～300 ms,仅音乐训练组在声调/韵母合适条件下,对韵母/声调的一致性进行深入分析,并诱发了更大的正波;在韵母违反条件下,声调违反相比声调合适诱发了更小的正波。在300～750ms,两组被试均在绝句末对诗句内出现的韵母和声调违反进行整合分析并诱发了广泛分布的负波。不过,对照组仅在声调/韵母合适条件下进行,而音乐训练组则在声调/韵母违反条件下完成此过程。综上,音乐训练组和对照组均会在诗句末完成押韵信息的整合加工,但是音乐训练组对韵律信息(尤其是声调)的加工更敏感和快速,并且对不同类型的违反有更精细的差异性反应
