具有认知诊断功能的计算机化自适应测验的研究与实现

构造具有认知诊断功能的计算机化自适应测验（Computerized Adaptive Testing,CAT）,关键在于设计不同于传统CAT的选题策略。本文采用先认知诊断后估计能力的方法,在诊断阶段用状态转换图描述特定认知领域中所有知识状态及这些状态之间的联系,以图的深度优先算法为基础设计选题策略;而在能力估计精细化阶段,每个被试所测项目,不仅与其能力估计值相匹配,且只与其所掌握的属性相关。本文采用蒙特卡罗模拟针对三种不同的属性结构进行试验,结果良好     

中医望诊中眼神跟踪与分析综述

望诊是中医四诊中的一种,也是中医查病的第一步。而眼睛是心灵的窗户,医师通过望眼神能够诊测一个人的身体健康状况,眼睛与身体的对应有众多说法,如"五轮八廓"等,因此眼神的跟踪与分析对于中医望诊十分重要。使用电脑对眼神的进行自动跟踪首先需要进行眼睛各部位的精确定位,包括眼皮、眼角、白睛、眼结膜、虹膜、瞳孔以及眼袋等;接着需要对眼睛的动作进行跟踪,包括眼球的转动、瞳孔的放缩等。对眼神的分析在定位与跟踪之后,由眼球各部分的形状、颜色、移动速度等信息结合相应的规则对病位、病性作出判断。本文综述了中医中望眼的一些经验总结,并给出了目前用于眼睛定位、跟踪的算法与思路。

Affaire Vincent L. : les maux de la fin

As called back it June 24th, Council of State in its press release, the Vincent L.’s case “raise scientific, ethical and human questions”. At first, to decide on the fate of this 38-year-old man, the administrative jurisdiction recovered from it in expert opinions asked to establish the existence or not of an unreasonable stubbornness. But the objectivity of the medical science cannot solve only this litigation where the outcome is the life or the death of a patient. That is why the court opened its doors to the ethical speech too. If in this case, the science could not exist without consciousness, if the legal word could not exist without the ethical word, it's because of the human dimension which fills this media and legal affair. So behind this patient's case, called now “the Vincent L.’s affair”, it's a question about the death, that of a young man in the incapacity to express its will. It's also a question of a family disagreement on the future of their son, brother, or husband. In this context, “politically and mediatically charged”, the administrative jurisdiction pronounced four times on the decision of the stop of Vincent L.’s treatment. The educational position of the French judges allowed to clear up statutory provisions of the Leonetti's act.     

Mindreading deception in dialog

This paper considers the problem of detecting deceptive agents in a conversational context. We argue that distinguishing between types of deception is required to generate successful action. This consideration motivates a novel taxonomy of deceptive and ignorant mental states, emphasizing the importance of an ulterior motive when classifying deceptive agents. After illustrating this taxonomy with a sequence of examples, we introduce a Framework for Identifying Deceptive Entities (FIDE) and demonstrate that FIDE has the representational power to distinguish between the members of our taxonomy. We conclude with some conjectures about how FIDE could be used for inference.     

Influence of Culture on Ethical Decision Making in Psychology

This study focused on the influence of American and Chinese cultures on consequentialism orientation in decision-making within the broader context of psychologists’ academic roles and responsibilities. In addition, this study hypothesized that educational level would affect culturally influenced ethical decision making in both cultures. Based on the American Psychological Association Ethics Code, 20 ethical scenarios in 5 domains in psychology were created and used to examine the influence of culturally ethical beliefs on psychologists’ decision making among 181 participants. The results indicated that significant cultural differences in consequentialism orientation differentiated Chinese and American participants and influenced their resolution of ethical issues.     

Prejudice‐reduction in Culturally Mixed Classrooms: The Development and Assessment of a Theory‐driven Intervention Among Majority and Minority Youth in Finland

The aim of this field experiment was to develop and assess an intervention promoting positive intergroup relations in culturally diverse schools. The intervention was based on extended contact and social learning and utilized behavioural journalism as its method. Intervention effects were assessed on out‐group attitudes, perceived importance of future contact, perceived peer norms and intergroup anxiety among ethnic majority (N = 583) and minority (N = 214) youth in grades 7–9 in Finnish secondary schools (total N_experimental = 388; total N_control = 409). As a result of the intervention, both groups showed a tendency to perceive future intergroup contact as more important, and this effect was most notable for younger participants and girls. Prototypicality of in‐group and out‐group peer models contributed positively to intervention effects. However, unexpectedly, the intervention also increased experiences of intergroup anxiety among the oldest participants. The results are discussed taking into account the developmental stage of the youth studied. Besides critically assessing the effectiveness of the intervention, recommendations for improving theory‐driven prejudice‐reduction and for the development of future interventions in culturally diverse contexts are given.

Seymour Sarason Remembered: “Plus ça change…”, “Psychology Misdirected”, and “Community Psychology and the Anarchist Insight”

The intellectual legacy of Seymour Sarason continues to serve as a critical resource for the field of community psychology. The present paper draws on one of Sarason’s favorite aphorisms and two of his seminal writings to suggest the relevance of ideas articulated 35–40 years ago for the current time. Each in their own way highlights the importance of unearthing and interrogating core assumptions underlying our research and our efforts to make a positive difference. The aphorism reminds us that the rhetoric of change is far easier to articulate than to enact and all too often ignores or disguises issues of power among actors. The “misdirection” of Psychology reflected his assertion that the asocial, acultural, and ahistorical nature of American Psychology reflected American culture more generally and ill prepared it to understand and engage in social change, particularly with respect to educational reform. The “anarchist insight” articulated his belief in interrogating the implications of the increasingly interdependent relationship of science and the state for the autonomy of scientists and scientific inquiry. The evidence‐based practice movement is offered as an example of the current day relevance of the aphorism and core insights of these two papers. The paper concludes with a plea to rekindle the discussion and continued examination of Sarason’s paradigmatic insights for the intellectual and social development of the field.     

Action orientation overcomes the ego depletion effect

It has been consistently demonstrated that initial exertion of self‐control had negative influence on people's performance on subsequent self‐control tasks. This phenomenon is referred to as the ego depletion effect. Based on action control theory, the current research investigated whether the ego depletion effect could be moderated by individuals' action versus state orientation. Our results showed that only state‐oriented individuals exhibited ego depletion. For individuals with action orientation, however, their performance was not influenced by initial exertion of self‐control. The beneficial effect of action orientation against ego depletion in our experiment results from its facilitation for adapting to the depleting task.
