对我国《人体器官移植条例》的伦理审视

《人体器官移植条例》已经颁布实施,人体器官移植是一种公认的涉及敏感伦理问题的外科手术。通过分析《条例》是否充分体现了国际通行的生命/医学伦理原则,研究了人体器官移植进行进一步伦理规范的必要性,提出了人体器官移植应遵循的具体医学伦理原则。特别强调了其中的"公正"实体原则和"伦理审查"程序原则。     

行为决策理论之父：纪念Edwards教授2周年忌辰

著名心理学家W ard Edwards对行为决策的学科形成与理论发展作出了巨大贡献。文章简要介绍了Edwards的生平,以主观期望效用模型和贝叶斯决策为核心回顾了Edwards的决策理论、主要成就及其对行为决策研究的学术贡献。文章并从行为决策领域的研究、科普、应用及人才培养等方面总结了中国行为决策研究的发展历程,以及Edwards的学术思想对中国行为决策研究的主要影响。文章展望了行为决策研究的前景,并呼吁更多的中国心理学工作者投身于行为决策研究。     

Failure to warn: How student race affects warnings of potential academic difficulty

In two studies, we document “failure to warn”—a reduced likelihood of warning Black students against potential academic difficulty compared to White students. In both studies, participants placed in the role of academic advisors saw a highly challenging academic course plan, attributed to either a Black or a White student, and gave Black students less warning about the potential negative consequences of taking on the proposed plan. Study 1 (N = 172) demonstrates this effect using undergraduate peer academic advisors, and Study 2 (N = 58) provides evidence that this effect is moderated by Internal Motivation to Respond Without Prejudice (Plant & Devine, 1998), suggesting that this effect is driven by the fear that discouraging an ambitious Black student might reflect prejudice. This well-intentioned concern can have the ironic consequence of leading the recipients of this advice into academic difficulties.     

Single case research results as clinical outcomes

The movement toward evidence-based treatments, interventions, or practices pressures single case research (SCR) to use statistical summaries which have broad credibility. These summaries also need to be easily understood and useful in schools and clinics. To date the effect size families, “proportion of variance” (R², Eta²) and “standardized mean difference” (Cohen's d, Hedges' g) have little popularity in SCR. This paper demonstrates a set of alternative Clinical Outcome indices widely used in the field of medicine: Risk Difference, Relative Risk, Relative Risk Improvement, and Odds Ratio, which compare patients in treatment versus control conditions. Translated to SCR designs, the baseline phase becomes the control condition, the intervention phase becomes the treatment condition, and improvement is defined as non-overlapping data between phases. The positive attributes of Clinical Outcomes are demonstrated: (a) easily interpretable results, (b) close relationship with concept of non-overlapping data, (c) minimal data assumptions, (d) minimal statistical expertise required, (e) multiple contrasts possible for diagnostic understanding, (f) exact confidence intervals for results, and (g) close relationship to Pearson R effect size family.     

Informed Consent in Emergency Research: A Contradiction in Terms

Improving the treatment of life threatening emergency illness or disease requires that new or novel therapies be assessed in clinical trials. As most subjects for these trials will be incapacitated there is some controversy about they might best protected whilst still allowing research to continue. Recent European and UK clinical trials legislation, which has effectively stopped research into emergency conditions, is discussed. Possible changes to these regulations are proposed.     

行为遗传学：解决面孔特异性问题争论的新思

面孔刺激的加工存在特异性,但“特异性”的具体内涵仍存在争议。面孔特异性假说认为面孔刺激具有特异性;而专家假说则认为存在特异性的是整体加工的模式。通过对相关领域近年来主要的研究结果的总结,发现争论中混淆了两个概念——加工类型和刺激类型,二者正交分解可将争论归纳为三个假设：1）面孔整体加工特异性的假设;2）面孔刺激特异性的假设;3）专家加工特异性的假设。在未来的研究中,行为遗传学可为解决该争论提供合适的方法     

创伤后心理复原的生理机制

心理复原是个体在经历对生命具有威胁的事件或严重的创伤后仍然能回复到良好适应状况的现象。对心理复原生理机制的研究存在两种研究取向：或从个人能力的角度,或从发展结果的角度。创伤记忆的抑制、大脑的可塑性、神经生物的调节以及基因、气质、情绪调节、认知过程、早期经验等保护因子的影响机制是研究的主要内容。文章最后对今后的研究进行了展望     

Creating a strategy for progress: a contextual behavioral science approach

Behavior analysis is a field dedicated to the development and application of behavioral principles to the understanding and modification of the psychological actions of organisms. As such, behavior analysis was committed from the beginning to a comprehensive account of behavior, stretching from animal learning to complex human behavior. Despite that lofty goal, basic behavior analysis is having a generally harder time finding academic support, and applied behavior analysis has narrowed its focus. In the present paper we argue that both of these trends relate to the challenge of human language and cognition, and that developments within clinical behavior analysis and the analysis of derived relational responding are providing a way forward. To take full advantage of these developments, however, we argue that behavior analysts need to articulate their unique approach to theory, to develop more flexible language systems for applied workers, and to expand their methodological flexibility. This approach, which we term contextual behavioral science, is meant as an evolutionary step that will allow behavior analysis to better capture the center of modern psychological concerns in both the basic and applied areas. Clinical behavior analysis is showing a way forward for behavior analysis to regain its vision as a comprehensive approach to behavior.     

Translational behavior analysis: from laboratory science in stimulus control to intervention with persons with neurodevelopmental disabilities

Throughout its history, laboratory research in the experimental analysis of behavior has been successful in elucidating and clarifying basic learning principles and processes in both humans and nonhumans. In parallel, applied behavior analysis has shown how fundamental behavior-analytic principles and procedures can be employed to promote desirable forms of behavior and to prevent or ameliorate undesirable forms in clinical, educational, and other settings. Less obviously, there has also emerged a small but identifiable bridging field that can potentially connect and inform both basic and applied behavior analysis. Although such translational behavior analysis uses laboratory methodologies, research targets are selected largely for their value in ultimate application to improve the human condition. I will discuss the distinction of translational behavior analysis from basic and applied behavior analysis and consider the potential contribution that translational research can make in the development of the science of behavior.
