NORMAL PEER MODELS AND AUTISTIC CHILDREN'S LEARNING

Present research and legislation regarding mainstreaming autistic children into normal classrooms have raised the importance of studying whether autistic children can benefit from observing normal peer models. The present investigation systematically assessed whether autistic children's learning of discrimination tasks could be improved if they observed normal children perform the tasks correctly. In the context of a multiple baseline design, four autistic children worked on five discrimination tasks that their teachers reported were posing difficulty. Throughout the baseline condition the children evidenced very low levels of correct responding on all five tasks. In the subsequent treatment condition, when normal peers modeled correct responses, the autistic children's correct responding increased dramatically. In each case, the peer modeling procedure produced rapid achievement of the acquisition criterion which was maintained after the peer models were removed. These results are discussed in relation to issues concerning observational learning and in relation to the implications for mainstreaming autistic children into normal classrooms.     

BEHAVIORAL MANAGEMENT AND TASK PERFORMANCE IN ORGANIZATIONS: CONCEPTUAL BACKGROUND, META-ANALYSIS, AND TEST OF ALTERNATIVE MODELS

In this study, we provide the conceptual background, meta-analyze available behavioral management studies ( N = 72) in organizational settings, and examine whether combined reinforcement effects on task performance are additive (sum of individual effects), redundant (combined effects are less than the additive effects), or synergistic (combined effects are greater than the sum of the individual effects). We found a significant overall average effect size of ( d. ) = .47 (16% improvement in performance; 63% probability of success), and a significant within-group heterogeneity of effect sizes. To account for this variation, we conducted a theory-driven moderator analysis, which indicated that money, feedback, and social recognition each had a significant impact on task performance. However, when these 3 reinforcers were used in combination, they produced the strongest (synergistic) effect on task performance. Based on our findings, we offer directions for future research, and suggestions for effective application of behavioral management at work.     

樟柳碱所致学习和记忆障碍动物模型的探讨

本实验采用水迷津法、步下法和步入法,用樟柳碱制备学习和记忆障碍的动物模型。结果表明,樟柳碱(10毫克/公斤)可使小鼠引起学习障碍,其表现为通过水迷津全程的时间延长,而且小鼠进入盲路的错误次数明显增多。樟柳碱(10毫克/公斤)可使小鼠引起记忆障碍,在樟柳碱的影响下,小鼠步下平台或步入暗箱的潜伏期明显缩短,并使它们的错误次数增多。本实验结果进一步表明,测定小鼠的记忆障碍,步入法似乎比步下法更为敏感。     

ON DAVIDSON'S REFUTATION OF CONCEPTUAL SCHEMES AND CONCEPTUAL RELATIVISM

Despite Donald Davidson's influential criticism of the very notion of conceptual schemes, the notion continues enjoying its popularity in contemporary philosophy and, accordingly, conceptual relativism is still very much alive. There is one major reason responsible for Davidson's failure which has not been widely recognized: What Davidson attacks fiercely is not the very notion , but a notion of conceptual schemes, namely, the Quinean notion of conceptual schemes and its underlying Kantian scheme-content dualism. However, such a notion simply cannot carry the weight of conceptual relativism for it does not catch the essences of conceptual relativism. Consequently, I argue that the very notion of conceptual schemes and conceptual relativism have survived Davidson's attack. Therefore, the failure of the Quinean notion of conceptual schemes and Kantian scheme-content dualism, even if Davidson can claim victory, does not mark the end of the very notion of conceptual schemes.     

SCIENCE AND RELIGION AS LANGUAGES: UNDERSTANDING THE SCIENCE–RELIGION RELATIONSHIP USING METAPHORS,ANALOGIES, AND MODELS

Many scholars often use the terms “metaphors,” “analogies,” and “models” interchangeably and inadvertently overlook the uniqueness of each word. According to recent cognitive studies, the three terms involve distinct cognitive processes using features from a familiar concept and applying them to an abstract, complicated concept. In the field of science and religion, there have been various objects or ideas used as metaphors, analogies, or models to describe the science–religion relationship. Although these heuristic tools provided some understanding of the complex interaction, they failed to address the broad nature of science and religion as well as the multifarious relationship between the two in a sociocultural context. Unlike the previous candidates, the concept of language, including the notions of linguistic worldview, linguistic identity, dialects, power, and bilingualism, offers a unique and comprehensive window through which science, religion, and the relationship between the two are seen with clarity.     

THE LANGUAGE OF RIGHTS AND CONCEPTUAL HISTORY

The historical problem about the origins of the language of rights derives its importance from the conceptual problem: of “two fundamentally different ways of thinking about justice,” which is basic? Is justice unitary or plural? This in turn opens up a problem about the moral status of human nature. A narrative of the origins of “rights” is an account of how and when a plural concept of justice comes to the fore, and will be based on the occurrence of definite speech‐forms—the occurrence of the plural noun in the sense of “legal properties.” The history of this development is currently held to begin with the twelfth‐century canonists. Later significant thresholds may be found in the fourteenth, sixteenth, and eighteenth centuries. Wolterstorff's attempt to find the implicit recognition of rights in the Scriptures depends very heavily on what he takes to be implied rather than on what is stated, and at best can establish a pre‐history of rights‐language.     

大学生的语言学习观念与英语学习策略研究

通过问卷对606名大学生进行调查,考察其语言学习观念和英语学习策略的特点及关系。结果表明:(1)在语言学习观念上,女生比男生的英语学习动机更强,大一女生明显认为英语学习难度大,外语学能观念随年级的升高而增强,文科生比理科生认为英语学习难度大,学习动机更强;(2)在英语学习策略上,性别、年级与6种策略都有一定关系,文科生在元认知、社交、情感、补偿、认知5种策略上的运用都显著高于理科生;(3)语言学习观念与英语学习策略有密切的关系。     

THE AVAILABILITY AND HELPFULNESS OF SOCIALIZATION PRACTICES

This study reports on the socialization practices most available to new employees and the extent to which these practices are seen by newcomers as being helpful in becoming effective organizational members. The results showed that socialization practices are differentially available to newcomers, and perceptions of their helpfulness vary. The helpfulness of various socialization practices as reported by newcomers appears to affect their feelings of subsequent job satisfaction and commitment.     

PERFORMANCE FEEDBACK INFORMATION AND ORGANIZATIONAL COMMUNICATION: EVIDENCE OF CONCEPTUAL CONVERGENCE

This study investigates the degree to which performance feedback information can be conceptually housed within an existing theoretical framework of organizational communication. If one's job can be conceptualized as a work information environment, then logically there should be some communality between organizational communication and performance feedback information. In this study 213 faculty members at Iowa State University completed a questionnaire addressing patterns of organizational communication within their respective academic departments and feedback on their own job performance provided them by multiple sources. In order to uncover any underlying congruence between the communication and feedback constructs, the data were subjected to canonical correlation analysis. The results revealed that the type of feedback, source of feedback, and perceived reliability of feedback sources were all found to interact in logical patterns with selected dimensions of organizational communication.     

目标结构与学习动机

本文概述了目标结构理论的形成及发展,并进一步论述了在教学中不同的目标结构,导致学生间不间的相互关系,从而使学生形成不同的学习动机,取得不同的学业成就。竞争目标结构激发的是能力中心的动机系统;个体化目标结构激发的是任务掌握的动机系统;合作目标结构激发的是道德中心的动机系统。由此,我们认为在当前的教学实践中应重视合作目标结构的建立。     

EARLY AND CURRENT READING AND SPELLING PRACTICES OF GIFTED SPELLERS

This study continued investigating the early reading and spelling experiences as well as the spelling practices of the finalists in the Scripps Howard National Spelling Bee, specifically the 1987 spellers who were considered gifted spellers. Two open-ended questionnaires were used: one for the parents of the spellers and one for the spellers. A follow-up telephone interview was conducted with a random sample of respondents. Results indicated that gifted spellers showed an early interest in language arts activities with 86% of the parents reporting that their children could read prior to formal schooling. The spellers considered themselves avid readers and indicated sophisticated metacognitive awareness whether reading or spelling. Results that suggested the spellers passed through developmental spelling stages far earlier than average children and relied on visual memory strategies, word meanings, and saying/writing words to master the orthography replicated findings from an earlier study.     

CONCEPTUAL INTEGRATION AND EMPIRICAL TEST OF JOB DESIGN AND COMPENSATION RELATIONSHIPS

A conceptual integration of job design and compensation draws on interdisciplinary job design, job evaluation, and labor economic theory. It is argued that job design influences the number and level of skills required and the degree to which jobs are physically aversive or hazardous. External labor markets also respond to skill and physical requirements. Job evaluation links job design and market forces by analyzing jobs'compensable factors that reflect these requirements, and then relating them to the market through wage surveys across firms. An empirical examination presents relationships between job design and pay or job evaluation measures. Strongly supportive results replicate in two separate samples (total n = 213 jobs) which differ in industries, job types, skill levels, job design measures, job evaluation measures, and labor markets. Motivational job design had higher job evaluation measures reflecting higher skill requirements, and mechanistic and perceptual/motor design had lower evaluation measures reflecting lower skill requirements. Biological design had lower evaluation measures reflecting physical requirements.     

TWO MODELS OF SPIRITUAL JOURNEY: YOGA AND CONFUCIUS

At first glance, to juxtapose the ascetical recommendations of Patanjali and Yoga next to the counsels of Confucius and the classical Chinese tradition seems improbable and even contradictory; indeed, each thrust contrasts very sharply with the other. India's Samkhya-Yoga tradition attests to an inward thrust, to a radical probing of what some have even described as the "frontiers of inner-space". From the very dawn of history, Yogis have pioneered an interior exploration of the psyche and human spirit; ultimately these Yogis proclaim the hidden value of each person, a dimension they call " purusa ". The Sanskrit word purusa has been variously translated as "consciousness", "spirit", "light", or simply as the authentic and genuine identity of the human being. Quite naturally then, the quest for realizing this purusa - identity became the preoccupation and all-consuming goal of the Yogis — even at the cost of an almost total disregard for the social order including the abandonment of such traditional values as our commonly accepted virtues of family, society, and social growth and development.     

神经颗粒素与学习记忆关系研究进展

神经颗粒素（Neurogranin,NG）是一种新发现的脑特异性蛋白质。它分布在多个脑区,特别在对学习记忆至关重要的脑区海马。该物质自发现以来,许多学者对其生物学作用,特别是与学习记忆的关系进行了大量的研究,并取得了相当的进展。研究表明NG参与了在学习记忆功能中起核心作用的脑内几种蛋白信号传导途径、长时程增强（Long-term potentiation, LTP）和长时程抑制（Long-term depression, LTD）等突触可塑性机制。NG基因敲除后,动物出现学习记忆能力缺陷。因而它可能涉及学习记忆的形成和巩固
