青少年结果预期与评价的ERP研究

大脑不断地对环境事件产生预期并将这些预期与实际结果进行比较, 通过对反馈刺激的结果评价以优化后续行为。采用抽奖式赌博任务范式, 操纵得奖的确定性程度, 利用事件相关电位技术(ERP), 研究青少年结果预期与评价的认知和神经电生理过程, 以成人作为对照组进行比较分析。研究结果表明：(1)在反映自动、快速结果评价的FRN上, 无论在高确定性还是在低确定性条件下, 青少年与成人均未表现出显著性差异; (2)组别与确定性程度在P300波幅上表现交互作用显著, 简单效应分析表明, 在高确定性条件下, 青少年组输、赢的P300波幅表现出差异; 而成人组输、赢的P300波幅无显著性差异。青少年对反馈刺激自动的快速结果评价能力已接近成人水平, 而对反馈刺激功能意义评价的控制加工能力还未发展成熟。     

研究生对导师负面评价的恐惧与师徒文化内隐观的关系

本研究旨在探索“怕导师”现象的文化原因,从师徒关系内隐观分析“怕导师”的影响因素。采用问卷调查和启动实验的研究方法,结果表明：（1）“怕导师”现象是存在的,即研究生害怕来自导师的负面评价。相比女性导师,研究生更害怕男性导师;导师的职称会影响研究生的害怕程度,当导师是教授时,研究生更为害怕。（2）研究生的师徒关系内隐观与其负面评价恐惧有关,越具有“学从师教”观念的人越害怕来自导师的负面评价。（3）“学从师教”文化观的启动会影响研究生对导师负面评价的恐惧程度。     

不同性质的评价对特质焦虑者抑制功能影响的ERP研究

特质焦虑者作为焦虑障碍易感性个体,会表现出对威胁性刺激的注意偏向,从而损害中央执行系统的抑制功能。但是不同情绪性评价刺激会如何调控特质焦虑者的抑制功能还不太清楚。为此,本研究以脑电P3b为抑制功能指标,要求高低特质焦虑组在三种不同评价下完成反向眼跳范式,考察不同性质的评价如何影响特质焦虑的抑制功能。行为结果发现,高焦虑组比低焦虑组错误率更高;积极评价条件下,高焦虑组的反应时慢于低焦虑组。ERP结果进一步发现,无评价条件下,高焦虑组的P3b波幅大于低焦虑组;低焦虑者在积极评价条件下的P3b波幅大于消极评价条件,但是高焦虑者没有显著差异。结果表明,积极评价会损害高特质焦虑者的抑制功能,而消极评价则促进了高特质焦虑个体的抑制功能。     

多值逻辑与语义赋值博弈

文章在扩展博弈上,给出了多值逻辑的语义赋值博弈的一般框架,避免了博弈者在多值逻辑的语义博弈中声明无穷对象的问题;然后通过Eloise赢的策略定义博弈的语义概念——赋值,证明了多值逻辑的博弈语义与Tarski语义是等价的;最后,根据语义赋值博弈框架对经典逻辑进行了博弈化。     

揭开“看牙难、看牙贵”的面纱

患者对现有分科看牙模式的失望和对牙科医疗机构的商业化模式的疑问,产生了“看牙难、看牙贵”的感叹。通过14年的全科牙医诊疗体系的实践,从结构影响结果的哲学角度提出全科牙医教育培训体系的建立和牙科产业链调整的设想。通过对历史上全科牙医的回顾,推测全科牙医和专科牙医的互补形式,将成为中国牙科医疗体系的“新式样”。通过对牙科医疗机构运行机制的分析提出了改善的建议。     

AMPLE智力模型——PASS智力模型的扩展

本文根据实验事实,对PASS智力模型进行扩展,并提出一个简称AMPLE的智力模型。这个模型基于脑的四个功能系统学说,包括注意（attention）、操纵（manipulation）、计划（planning）、学习（learning）和评估（evaluation）等过程。它是一个囊括觉、知、情、意诸成分在内的全面的智力模型。     

团队互动过程研究述评

团队的特性在于成员间有相互作用,团队效能很大程度上取决于团队成员间的互动过程。文章从团队互动的视角概览了新近有关研究。概括出：（1）团队互动过程的行为要素,包括沟通、协调、相互支持、冲突、领导行为、目标行为等;（2）伴随互动过程涌现的情感状态及互动风格;（3）团队互动的测评;（4）团队互动培训。提出进一步研究有待加强直接以团队互动过程为对象,建构高效团队互动的核心模型等。     

Mentoring Nurses in Familial Cancer Risk Assessment and Counseling: Lessons Learned From a Formative Evaluation

Background. As familial cancer genetic services moves into community practice increased numbers of trained health professionals are needed to counsel individuals seeking cancer risk information. Nurses have been targeted to provide cancer risk assessment and counseling. To help prepare nurses for this role, a 5-day training in familial cancer risk assessment and counseling followed by a long-distance mentorship to support continued skill development in the work environment was conducted by Fox Chase Cancer Center, Philadelphia, PA. Methods. Four cohorts (N = 41) have completed the training and were randomized to either an immediate or delayed mentorship. A formative evaluation assessed the nurse’s ability to consult with other genetic health professionals and build self-efficacy in counseling skills via responses to questionnaire. A post-mentorship interview evaluated the usefulness, timing and length of the mentorship. Results. For both groups, there was a statistically significant improvement in self-efficacy for all skills from baseline to 6 months and an increased number of nurses consulting with genetic health professionals. All the nurses reported the value of the mentorship and those with less cancer risk counseling experience prior to the training needed support and resources for further skill and program development. Lessons learned from this formative evaluation are provided.     

Demonstrating Support for the Formative and Summative Assessment Paradigm in a School-Based Intensive Mental Health Program

We illustrate the use of formative and summative assessment in evaluating a therapeutic classroom program for children with serious emotional disturbances. Information was analyzed based on data gathered for clinical decision-making during treatment (formative assessment) and measurement of outcomes at discharge (summative assessment) from a school-based Intensive Mental Health Program. Results indicated that overall ratings of daily indicators of behavior across all environments (therapeutic classroom, neighborhood school, and home) were predictive of functioning at discharge. An ecological approach during the formative assessment period of evaluation is important as compared to only examining individual environments. Formative assessment techniques can predict scores on a summative assessment measure. Thus, we found supportive evidence for the formative and summative procedures used in the Intensive Mental Health Program for therapeutic interventions, clinical decision-making, and outcomes assessment.     

Lessons Learned from the Intensive Mental Health Program: A School-based,Community Oriented Program for Children with Serious Emotional Disturbances

The Intensive Mental Health Program meets the needs for services in school systems for children with serious emotional disturbances and for training graduate students in clinical applications with a difficult-to-serve population. We address the range of challenges and rewards experienced in the development of the comprehensive intervention program, the continued maintenance of program elements, and the program evaluation.
