高效率学习的心理机制研究

本课题通过一系列研究,发现要实现高效率学习,应在知识呈现符合学生认识规律的情况下,具备以下五个主要心理要素:选择性注意是实现高效率学习的前提,元认知是高效率学习的监控系统,非智力因素是高效率学习的动力源泉,学习策略是实现高效率学习的保障,内隐认知,特别是内隐学习是高效率学习的特殊形式。     

三维倾斜平面的返回抑制

以随机点立体图为实验材料,采用三维空间线索－目标范式,将刺激呈现于同一视野位置以排除眼跳因素干扰,通过观察有意注意倾斜平面和无意注意倾斜平面与测试平面间的方向一致性和角度一致性对检测平面加工的影响,探讨了注意在不同倾斜平面间的转移是否产生返回抑制。结果表明：（1）以视差线索构造的三维视觉空间中,存在与注意有关的返回抑制效应;（2）无意注意加工能导致返回抑制,注意引导平面比无意注意平面引起更大的抑制效应。本研究的结果支持Posner返回抑制是由注意转移所致的观点     

图形项目记忆与位置来源提取的ERP研究

采用事件相关电位（ERP）方法研究大学生图形项目记忆与位置来源提取新/旧效应的时、空分布特征。学习屏幕左侧（或右侧）呈现的图形后在屏幕中央呈现某一测验项目（已学图形或新图形）,对受试者进行两类测验：其一是判断该项目是否已学过;其二是将从某侧学过的测验项目判断为目标,而将其它测验项目判断为非目标的来源测验（排除任务）。实验结果表明：图形位置来源提取比项目再认新/旧效应的头皮分布更广,持续时程更长;与前人相同实验范式的研究结果相比,本研究位置来源提取效应的头皮分布范围较广;非目标-旧图形与目标图形新/旧效应的头皮激活程度不同。上述结果说明：图形位置来源提取比项目再认激活的大脑区域更多,这与双重加工模型的观点一致;实验范式和来源知觉的特性共同调节来源记忆新/旧效应的时、空分布特征;意识水平对来源信息提取的新/旧效应存在一定的影响     

Transferring the technology,policy, and management concept from the Netherlands to China

The literature on policy transfer between countries and organization has seen rapid growth. Whether framed in terms of policy transfer, institutional transplantation, imitation and emulation or copying policy models and ideas, a sizeable number of determinants for success have been identified to understand why such conceptual or institutional transfers grow out to become successes or failures in their countries or organizations of adoption. What is much less common is to describe such a process through the lens of participants inside this transfer. This paper is an attempt to do just that. It will tell the story of the higher-educational concept of Technology, Policy and Management from Delft University of Technology in the Netherlands to Harbin Institute of Technology in China, studied by means of participatory observation. The keys and clues for successful transplantation from the literature will subsequently be compared with the experiences from this case, and additional lessons, some of which are specific to Western-Chinese mutual learning, are formulated.

He publishes and lectures mainly on subjects of cross-national policy transfer, cross-cultural management and transport infrastructure policy. He is also responsible for the international master program Engineering and Policy Analysis, for which he has helped to set up a Chinese counterpart with the same name.

The reconfiguration of task set has no effect on the efficiency of feature search

In this study, we investigated whether or not the reconfiguration of a set task could modulate the efficiency of feature search. In Experiment 1, target set size was manipulated. The results revealed that enumerating targets defined by color yields a much steeper slope when executed simultaneously with a discrimination task than when done singly. However, when distractor set size was manipulated, there was no significant difference in the efficiency of individualizing targets from distractors between the two task conditions, no matter whetherthe search was guided by bottom-up information (Experiment 2) or top-down information (Experiment 3). Drawing upon these results, the authors propose that (1) an additional task can impair the efficiency of enumeration, resulting in a steep slope of counting even when target set size is quite small, and (2) in feature search, the visual system first reconfigures the task set to match the input feature information and then detects the targets with an optimal efficiency, which does not support the theory proposed by Di Lollo, Kawahara, Zuvic, and Visser (2001; Di Lollo, Smilek, Kawahara, & Ghorashi, 2005).     

术前谈话与患者的知情同意权

告知说明义务是医师的法定义务,知情同意权是患者的法定权利,术前谈话是外科医师履行告知说明义务和手术患者实现知情同意权的共同方式。外科医师应深入理解患者的知情同意权,合理履行告知说明义务,临床实践中做到告知说明内容充分,变更手术重新告知说明,避免使用穷尽式列举,确定签字人身份合法且具有完全民事行为能力。

The Effect of Disruptions During Counseling on Recall of Genetic Risk Information: The Case of Cystic Fibrosis

Genetic counseling is a communication process with two main functions: information provision and supportive counseling. The information transmission function may be compromised by disruptions that occur during counseling. At least two mediators are possible: (a) disruptions may interfere with memory by creating distractions and divided attention during encoding or (b) disruptions may degrade the flow of interaction which requires that participants engage in conversation repair rather than the task at hand. This study examined both alternatives in a group of parents (N=20 families, 40 individual parents) whose infant had received a newborn screening for cystic fibrosis (CF). Upon arrival at the hospital, each parent completed a questionnaire designed to assess his or her knowledge of CF. Their interaction with the genetic counselor was videotaped and coded for the presence of disruptions. Six weeks after the counseling, parents again completed the knowledge measure. The data showed a direct negative effect for disruptions during counseling on memory for CF-related risk information six weeks later. Disruptions also produced the anticipated effect on conversation, but counter to expectations, interruptions of conversation flow was positively associated with knowledge at time 2.
