Interactional Styles of Bullies and Victims Observed in a Competitive and a Cooperative Setting

Observational data were used to examine the interactional styles of bullies and victims while they participated in 2 different games: 1 cooperative and 1 competitive. Participants included 17 bullies, 18 victims, and 35 controls (all aged 8–11 years) selected through a peer nomination questionnaire. Bullies and victims were observed 4 times in total: twice during the cooperative game and twice during the competitive game, each time paired with a partner of opposite status or control status. Results indicated that when bullies and victims interacted together, bullies showed a dominant style in the dyad, often regulating and opposing victims' initiatives. Victims, on the other hand, complied with bullies' requests and presented a submissive style of interaction. However, interactions involving control partners indicated that (a) bullies opposed those partners' initiatives less frequently and (b) victims tended to affirm themselves by asking for help and explanations. These data provide evidence for an interactional model in explaining the dynamics between bullies and victims.     

Demand characteristics and research into drug use

Abstract

Health research makes frequent use of verbal reports; and such reports are usually assumed to be the surface indicants of measurable entities such as attitudes, beliefs, intentions, etc. which reside inside the person. It is our assertion that verbal reports themselves are motivated and variable; they are functional and context-dependent and their meaning and significance are localised. Consequently discourse cannot be treated as if it were fixed and categorical data to be retrieved from memory by asking questions that appear objective or disinterested. A method is postulated, using a social perception analogy with signal detection (SD) theory. The method allows for the assessment of subject criterion, and permits an examination of signal-strength in terms of the researcher's motivation. Data are evaluated in terms of their “robustness”, a measure which derives from the variability of response in different contexts, and under different elicitation procedures. The method requires few assumptions to be made about the “truth” or “falsity” of verbal reports. It focuses on the types of social activities that are performed by utterances and thus on the contextual variability revealed by asking questions in different situations and in different ways. This procedure does not presume a direct correspondence between verbal reports and mental representations.     

中外两种推理理论的实验比较研究

通过两个实验对中国学者提出的“推理题与推理者的推理知识双重结构模型”和Evans提出的“双重加工理论”进行了实验比较研究。实验一通过两种评定方法对相应性质命题进行评定后所得实验结果表明Evans等(1983)有关“信念效应”研究中的“结论可信性”变量可以视为与胡竹菁等(1996)实验中的“内容正确性”变量是同一性质的变量; 实验二根据“形式正确性”和“内容正确性”两个自变量设计的推理实验结果与Evans等(1983)的研究结果基本一致; 但增加“内容熟悉性”这一自变量设计的推理实验结果表明“推理题与推理者的推理知识双重结构模型”比Evans提出的“双重加工理论”能更好地解释推理者对性质三段论的推理结果。     

FOK研究中一种新的标准测验——过度重复学习

提出FOK研究中一种新的标准测验形式——过度重复学习,并验证过度重复学习作为FOK研究的标准测验的可行性;另外还比较了作为标准测验,过度重复学习与再认的差别。同时,还探索了FOK判断中存在的两种错误类型——替代性错误和忽略性错误在FOK判断等级和标准测验成绩方面的差异。两个实验结果表明：FOK判断在预期随后的标准测验(过度重复学习和再认)成绩上是有准确性的;过度重复学习可以作为一种标准测验。实验结果还显示：替代性错误比忽略性错误的FOK判断等级要高;且无论是用再认还是用过度重复学习做标准测验,都能检验出两种错误类型项目在记忆激活强度上的差异。     

Insight in frontotemporal dementia: conceptual analysis and empirical evaluation of the consensus criterion "loss of insight" in frontotemporal dementia

The objective of this study was to suggest a new formulation of the core research diagnostic consensus criterion "loss of insight" in frontotemporal dementia (FTD). Eight patients with FTD (diagnoses made by interviews, medical and neuropsychological examination, CT scan, and regional cerebral glucose metabolism measured by positron emission tomography (PET) participated in the study). The results indicated that insight was present in three out of eight patients, and that insight appears to be a heterogeneous concept. Two types of insight emerged: Emotional insight associated with frontotemporal functions, and cognitive insight, related to posterior cognitive functions. These results suggest that loss of insight should not serve as a core criterion on FTD, but serves well as a supportive criterion of the disease.     

A Stimulus-Oriented Approach to Memory

ABSTRACT— Our understanding of short-term recognition memory can be enhanced by careful choice and control of test materials. Theory-driven manipulation of memory test stimuli, including visual textures, human faces, and complex sounds, minimize individual differences and make it possible to predict recognition performance for specific combinations of stimulus items. This stimulus-oriented approach to memory reveals that stimulus similarity plays two different important roles in recognition memory. By exploiting tools used in psychophysics, it is possible to generate mnemometric functions—detailed "snapshots" that capture key features of subjects' memory strength.     

一个新的测量过程框架——对引入认知加工模型的再思考

从认知任务分析出发的测验设计,核心在于从认知加工的角度对项目底层作答机制作出解释。其中,能够刻画任务难度的模型最有可能与心理计量模型相结合。因而,具备成熟难度法则的各种小型理论或通用理论可以进入测量过程,实现从纯粹误差结构控制的测量到内容导引的测量的转变。在这样一个框架之下,理论对任务上作答过程的理解是否恰当,刺激特性变量与任务难度关系的揭示(即难度法则)是否准确,可以在测量的过程中进行证伪。项目反应理论还未及很好回答的效度问题,可望在这一拓展的框架中获得圆满解决。本文为新的测量过程框架提供了一个示意图。     

药品临床试验的伦理规范与医学科技进步--对非洲等地开展HIV药品临床试验的思考

目前,在非洲等地进行的HIV药品临床试验已成为国际上最有争议的话题之一.药品临床试验促进了医学科技的进步和发展,但同时带来了一些突出而复杂的伦理问题.面对这一难题,我们应正确看待医学科技进步与伦理之间的关系,以"尊重、公正、不伤害、受益"这一伦理基本原则指导HIV药品临床试验,促进医学和伦理道德的共同进步、协调发展.     

哲学的困境和黑格尔的幽灵——关于"中国无哲学的反思"

When Western science was introduced to modern China, more translated words were used to express fundamental concepts and terms than borrowed words. The process of academic translation, commensuration, and communication between Western and Chinese philosophy is a process of comparative philosophical research. Nowadays, however, it seems that Chinese philosophy is evaluated by a Western Hegelian criterion. This leads to the debate over whether or not China has philosophy. But it is meaningless to argue about whether or not China has the name of philosophy. The key issue is whether or not China has the actuality of philosophy. Looking at the history of Western philosophy, it seems that the Hegelian definition of philosophy was the only one that existed in Europe. However, during the last 200 years after Hegel that the two main philosophical trends of positivism (scientism) and irrationalism developed from anti-Hegelianism or “Spurning Metaphysics.” As metaphysics is being reconstructed, the ghost of Hegel has reappeared. It is clear that in the future, philosophy will evolve from the development of human metaphysics or cultural philosophy. It is a process of the “negation of negation”: from traditional metaphysics to the spurning of metaphysics, and then to human metaphysics.

读者的元理解监测为什么不精确？

精确的元理解监测对随后的元理解控制和阅读理解有重要作用,但是,通常情况下,读者的元理解监测并不精确。回顾20余年的元理解监测研究,发现元理解监测的精确性主要受制于阅读材料特征、监测线索与标准测验特征等因素。未来研究应注意元理解监测的判断形式、监测线索及评价标准对元理解监测精确性的交互关联影响。
