初中生社会技能角色扮演测试的多因素实验研究

以初中生为被试,以社会技能为目标行为,对角色扮演测试进行研究,探讨其影响因素和外在效度。研究采用２×２×２三因素实验设计,通过现场测试、刺激控制和问卷调查相结合的实验方法,着重探讨了角色扮演情境内容、测试指导语、实验助手的交往方式三个因素对被试行为的影响,证明了角色扮演行为随情境操纵的变化而变化,并发现在采用个体化的测试情境、低水平要求的指导语及非结构化的交往方式的情况下,外在效度最高。另外,多元回归统计分析表明被试性别、已有水平等对角色扮演行为水平也有影响。     

Influence Opportunities and the Development of Argumentation Competencies in Childhood

Whether argumentation competencies are associated with the kind of influence opportunities children have in their lives is the focus of this study. The hypothesis is that when children have the opportunity to initiate and evaluate arguments, hear others make and examine arguments, and participate equally in resolving disputes, children are able to develop their argument skills. Four argumentation competencies associated with critical discussions of proposals are identified: creating consensus about problematic situations, advocating proposals, facilitating behavioral commitment, and integrating identities. Second, fourth, and sixth grade children completed tasks that assessed their influence opportunities and argument competencies. Children who perceived themselves to have many collaborative influence opportunities, that is, opportunities in which they could engage in mutual influence, had more highly developed argument competencies than children who did not have such opportunities. As predicted, this relationship occurred with the argument competencies of problem conception, proposal advocacy and facilitating commitment. Measures of non-collaborative influence opportunities were not associated with argument competencies. Together, the results suggest that discussions in which children are given the opportunity to influence and be influenced with arguments may provide the best context for children to develop their argument skills.     

西安市小学生中独生与非独生子女个性品质的比较研究

本文研究了西安城区１０所小学７８７名独生与非独生子女个性品质方面的情况。我们设计了有１８个行为项目的教师问卷（每项按五等评分）及家长问卷;对结果进行了因素分析,据所聚类的项目内容,将所得四个因素命名为人际关系、自我中心、学习动力和独立性,进行多变量的变异数分析结果表明,独生子女的自我中心和学习动力比非独生子女强烈;而独立性却比非独生子女差．这说明独生子女在个性品质方面既有缺点,也有优点,不能说得一无是处;关键在于正确的教育思想和方法。     

TEACHING JANITORIAL SKILLS TO THE MENTALLY RETARDED: ACQUISITION,GENERALIZATION, AND MAINTENANCE

A task analysis of janitorial skills required for cleaning a restroom was performed. Six subtasks with a total of 181 component responses were identified. Subjects were required to progress through a series of four prompt levels ordered generally from more to less direct assistance for 20 of the most difficult component steps. Another series of four prompts, ordered from less to more direct assistance, was used to teach the other 161 responses. Subjects progressed to the next more intense prompt level contingent on a failure to respond appropriately with less assistance. A multiple baseline across subjects as well as the six subtasks was employed to evaluate the efficacy of the procedures. Six moderately retarded adolescents were trained in their public school. The results show rapid response acquisition, skill generalization to a second restroom, and maintenance of the newly learned behavior. The present research provides evidence of a model for analyzing and training vocational skills to the mentally retarded.     

A parent advice package for family shopping trips: development and evaluation

THIS ARTICLE REPORTS ON THE PRIMARY STEPS IN THE DEVELOPMENT OF PARENT ADVICE FOR POPULAR DISSEMINATION: (a) developing advice for one specific problem situation, family shopping trips; (b) testing the advice program for benefit to children and convenience to adults; and (c) packaging the advice so it can be used successfully by interested parents. Systematic observation of 12 families using the written advice package on shopping trips revealed its effectiveness in reducing child disruptions and increasing positive interactions between parents and children. These findings, along with interview information from families, showed that the package is usable, effective, and popular with both parents and children, and thus is ready for dissemination to a wide audience of parents-a step that in itself should involve research and evaluation.

空间导航的脑网络基础和调控机制

空间导航在生活中时刻发生,空间能力衰退是阿尔兹海默症的重要早期表现。早期关于空间导航神经机制的研究主要关注单个脑区的特异性功能,但这些脑区如何交互以整合不同模态的信息支持复杂导航行为尚不清楚。脑成像技术、脑网络建模方法和神经调控手段的发展,为在脑网络水平理解人类空间导航的认知神经机制提供了重要研究手段。本研究试图融合空间导航认知神经机制研究的最新进展,借助脑网络建模、大数据分析、微电流刺激等前沿研究手段,研究空间导航脑网络的关键拓扑属性特征(如模块化、核心节点等),探寻该功能特异性神经网络的重要影响因素和调控机制,并构建空间导航的脑网络理论模型。研究成果将有利于理解人类复杂导航行为的脑网络基础,为阿尔兹海默症等相关认知障碍脑疾病的筛查和诊断提供重要参考。     

The role of visuo-spatial abilities in environment learning from maps and navigation over the adult lifespan

Visuo-spatial abilities have an important role in environment learning. The aim of the present study was to explore whether these abilities relate to spatial recall after learning an environment from a map or a video, and irrespective of the learner's age (from youth to old age). The study involved 431 participants from 25 to 84 years old, who were assessed for their visuo-spatial working memory, object-based mental rotation, and perspective-taking abilities. Then, they learned environments from a map and a video, and performed pointing, map drawing, and route repetition tasks after learning from each type of input. The resulting path models showed that age related to visuo-spatial abilities and (in some cases) to spatial accuracy, too. After accounting for age, visuo-spatial abilities also related to spatial recall performance, whatever the type of learning input, especially in pointing tasks and, to a lesser degree, in map drawing and route repetition tasks. Overall, the relationship between individual visuo-spatial abilities and environment learning relates to the learning input and the type of task used to assess recall. This relationship was found in a large and diverse sample of participants ranging from youth to old age.     

Muscular fitness,motor competence,and processing speed in preschool children

ABSTRACT

The aim of this study was to examine the relationship between muscular fitness and motor competence and processing speed in preschool children. Eighty-four preschool-aged children were recruited and underwent assessments for muscular fitness (muscular endurance and power), motor competence, and then participated in an auditory oddball task. The findings showed that muscular fitness and motor competence were associated with shorter reaction times after controlling for confounding factors. These findings provide tentative support for a positive association between muscular fitness and motor competence and processing speed in preschool children.

Seeing by Feeling: Virtues,Skills, and Moral Perception

Champions of virtue ethics frequently appeal to moral perception: the notion that virtuous people can “see” what to do. According to a traditional account of virtue, the cultivation of proper feeling through imitation and habituation issues in a sensitivity to reasons to act. Thus, we learn to see what to do by coming to feel the demands of courage, kindness, and the like. But virtue ethics also claims superiority over other theories that adopt a perceptual moral epistemology, such as intuitionism – which John McDowell criticizes for illicitly “borrow[ing] the epistemological credentials” of perception. In this paper, I suggest that the most promising way for virtue ethics to use perceptual metaphors innocuously is by adopting a skill model of virtue, on which the virtues are modeled on forms of practical know-how. Yet I contend that this model is double-edged for virtue ethics. The skill model belies some central ambitions and dogmas of the traditional view, especially its most idealized claims about virtue and the virtuous. While this may be a cost that its champions are unprepared to pay, I suggest that virtue ethics would do well to embrace a more realistic moral psychology and a correspondingly less sublime conception of virtue.
