THE EFFECTS OF BEHAVIOR SKILLS TRAINING ON CORRECT TEACHER IMPLEMENTATION OF NATURAL LANGUAGE PARADIGM TEACHING SKILLS AND CHILD BEHAVIOR

Natural Language Paradigm (NLP) is a naturalistic teaching strategy for children with autism that increases immediate and delayed imitative utterances, spontaneous utterances and new words, and production of utterances. NLP includes increasing child choice, varying stimulus items, loose shaping contingencies for communicative attempts, and providing reinforcers with a direct relationship to the response. Only one previous study investigated the effects of behavioral skills training (BST) on staff acquisition and generalization of implementation of NLP and child behavior. A BST package of instructions, modeling rehearsal and feedback, was used to train teachers to implement NLP teaching procedures with three pre‐school children with autism spectrum disorder. Training increased correct teacher performance systematically across all three teachers during NLP teaching sessions and with children for whom teachers did not directly receive training. Correct teacher performance increased appropriate child vocalizations and decreased maladaptive behavior for four of six children. BST is effective in quickly training teachers in the generalized implementation of complex NLP teaching procedures across children. Copyright © 2012 John Wiley & Sons, Ltd.     

决策任务反应模式对偏好反转的影响

在经典彩票问题研究的基础上,探讨了匹配和选择两种反应模式及其先后顺序对被试偏好反转的影响,以及被试性别与其偏好反转的关系。研究结果发现:(1)反应模式的变化导致偏好反转的发生;(2)偏好反转存在反应顺序效应,先匹配后选择条件下的偏好反转率显著大于先选择后匹配条件下的偏好反转率;研究结果不支持后悔理论;(3)不同性别被试在选择和匹配任务中的偏好及其反转率没有显著性差异。     

智力和元认知技能在发现学习中的作用:任务复杂性的影响

采用自编的计算机模拟发现学习任务,以49名大学生为被试,探讨了在简单和复杂发现学习任务中,智力、元认知技能和学习成绩三者之间的关系。结果发现:在简单任务中,三者关系基本符合混合模型;进行过多的元认知活动,并不能提高学习效果。在复杂任务中,智力对学习成绩起主要预测作用。随着任务复杂性的增加,智力对学习的影响也随之变化,符合难度阈限理论的假设。任务复杂性不同时,智力、元认知技能和发现学习成绩之间的关系也不同,在一定程度上验证了难度阈限扩展理论。     

THE LEARNING OF ENGLISH AS A SECOND LANGUAGE AND THE DEVELOPMENT OF THE EMERGENT BILINGUAL REPRESENTATIONAL SYSTEMS

A developmental theory of bilingualism was advanced for children acquiring English for the first time at school in developing countries. It was argued that there would be a separation of an English representational (meaning) system from the mother-tongue representational system following greater competence in English. Degree of separation of representational systems for three groups of children was measured by two indices derived from word association data. The theory received support on one index but was not supported on the other index. It was concluded that theories that postulate separate representational systems for adult competent bilinguals more adequately account for the findings of this study.     

THE IMPACT OF I/T/A ON LOW‐LEVEL READERS IN THE JUNIOR HIGH SCHOOL

The Initial Teaching Alphabet was contrasted with traditional orthography in remediation classes for slow readers at the junior high school level. Using the Iowa Test scales as the measure of achievement, the Initial Teaching Alphabet group demonstrated statistically superior gains. Differences in motivation and attitude were ruled out as major contributors. The Initial Teaching Alphabet potential as a remediation technique for higher grade levels appears to be dependent upon curriculum standardization and teacher preparation.     

决策权力和社会角色对混合动机冲突决策的影响

以最后报价谈判问题为实验材料,考察了混合动机冲突情境中决策权力和社会角色的影响。结果表明:(1)决策权力对决策者的决定有显著影响。拥有分配权的决策者倾向于采取竞争策略,拥有要求权的决策者倾向于采取平均分配策略,拥有否决权的决策者倾向于采取合作策略。(2)社会角色对决策者的决定有显著影响。与陌生人角色相比,担任好朋友角色的决策者决定得到的点数明显地更低。     

恐惧情绪对大鼠学习记忆的影响

通过对４组不同处理背景动物操作条件学习的实验研究,观察强噪音下恐惧情绪对动物学习、记忆的影响以及怎样通过系统脱敏来减少恐惧在其中的作用。结果发现：恐惧组大鼠的操作条件学习具有第一次联系（健盘与食物之间）成功所需时间短、旧技能遗忘快、重新学习次数多和学习成绩差等特征;恐惧组大鼠与学习无关的恐惧行为增多,严重干扰学习的控制加工过程,影响学习任务完成;强噪音脱敏组大鼠学习过程、学习成绩的各项指标与控制组无差异。     

观察式学习条件下类别维度与家族相似性类别学习

在观察式学习条件下考察类别维度数量（三维度类别、六维度类别、九维度类别）,类别维度结构（线性分离结构、非线性分离结构）的变化对家族相似性类别学习的影响。结果表明：观察式学习条件下,类别维度数量的变化对样例学习无影响,对特征学习有影响,表现在特征正确再认数量上有差异,但特征再认正确率上无差异;类别维度结构的变化对样例学习有影响,对特征学习无影响,表现在样例正确再认数目上线性结构大于非线性结构。     

语文学困生与学优生阅读理解监控的发展研究

本研究采用错误检测法和理解自信度评价法,以错误觉察人数、错误觉察成绩、理解自信度评价成绩、阅读时间和阅读理解成绩为分析指标,探讨了不同年级语文学困生与学优生的阅读理解监控特征。结果发现:(1)语文学困生的阅读理解监控能力明显低于学优生;(2)学生对低难度错误信息的理解监控能力明显高于对高难度错误信息的理解监控;(3)随着年级的增长,学生的阅读理解监控能力也随之提高。     

学习态度与学习行为的相关性研究

按照态度的结构理论,态度包含认知、情感和意向三种成分。该研究采用问卷测查的方式,考察了学习态度中的三种成分与学习行为的关系。结果表明,影响学习行为最主要的因素不是认知,而是意向和情感。所以要使学生真正形成一种能够促进学习行为的积极的学习态度,关键在于使他们产生对学习的愉悦体验和强烈的投入意愿。     

AN EVALUATION OF THE RELATIVE EFFICACY OF AND CHILDREN'S PREFERENCES FOR TEACHING STRATEGIES THAT DIFFER IN AMOUNT OF TEACHER DIRECTEDNESS

The manner in which teachers mediate children's learning varies across early childhood classrooms. In this study, we used a multielement design to evaluate the efficacy of three commonly implemented strategies that varied in teacher directedness for teaching color‐ and object‐name relations. Strategy 1 consisted of brief exposure to the target relations followed by an exclusively child‐led play period in which correct responses were praised. Strategy 2 was similar except that teachers prompted the children to vocalize relations and corrected errors via model prompts. Strategy 3 incorporated the same procedures as Strategy 2 except that a brief period of teacher‐initiated trials was arranged; these trials involved the use of prompt delay between questions and prompts, and correct responses resulted in tokens and back‐up activity reinforcers. Children's preferences for the different teaching strategies were also directly assessed. Strategy 3 was most effective in promoting the acquisition and generalization of the color‐ and object‐name relations and was also most preferred by the majority of children, Strategy 1 was the least effective, and Strategy 2 was typically the least preferred. Implications for the design of early educational environments based on evidence‐based values are discussed.     

MAU程序和自由讨论的群体决策质量比较

采用实验室研究方法,比较了在信启、不分享条件下多特征效用模型(MAU)决策程序和自由讨论对群体决策质量的影响,并对影响MAU决策质量的主要因素进行了初步探讨。结果发现：(1)MAU程序可以较好地克服群体动力学方面的一些消极影响,表现出挖掘信息(尤其是非分享信息)的充分性。但MAU程序在被试的态度和社会交互作用等心理效标上并未显示出优势;(2)在MAU条件下,群体规模的增大对分享和非分享信息的讨论量无显著影响。而任务难度效应要和群体规模一起才能起到作用。     

小学教师集体效能及其对自我效能功能的调节

通过对28所小学1299名教师的问卷调查,作者主要探讨了教师集体效能在解释学校间教师心理特征各方面差异时的重要性,及其对自我效能预测功能的调节作用。多层分析结果表明,（1）教师自我效能对教师心理特征各方面的表现有显著的预测作用,这一预测作用存在学校间的差异;（2）教师集体效能高的学校,教师的工作满意度、内在动机、工作投入、同事关系满意度平均较高,离职倾向较低;（3）教师集体效能对自我效能与工作满意度等心理特征各方面的关系有显著调节作用,集体效能高的学校,自我效能对教师心理特征诸方面表现的预测力较强     

学习支持对基于计算机模拟的发现学习的影响

研究了针对发现活动的意义性的解释性支持 (IS)、针对其系统逻辑性的实验性支持 (ES)以及学习者的推理能力对基于模拟的科学发现学习的影响。设计开发了关于浮力的模拟软件 ,被试为北京十四中初二学生 80名 ,采用 2 (有 /无IS)× 2 (有 /无ES)× 3(推理能力 )的混合实验设计。结果发现 ,推理能力在原理性知识、直觉性理解测验以及学习者所设计实验的质量上有显著的主效应。IS在原理性知识和灵活应用测验上有显著的主效应。ES与推理能力在原理性知识测验上有显著的交互作用 ,ES在学习者所设计实验的质量上有显著的主效应。这一结果说明 ,发现活动的意义性和系统逻辑性对基于模拟的发现学习有重要的制约作用 ,应该针对这两个侧面设计相应的学习支持     

任务难度、决策培训诸因素对群体决策的影响

通过3人群体的人员选拔模拟实验。考察了任务难度、群体结构和决策培训三个变量对群体决策信息取样的影响。结果显示：(1)部分证明了Stasser的信息取样模型,分享信息具有讨论的优势,同时偏好是影响群体决策的中介因素,但是,该模型只适合于任务难度较大的情况;(2)设立具有信息管理作用的领导者这种群体结构在信息取样中没有表现出主效应,它只是通过与决策培训和任务难度一起对信息取样产生影响;(3)策略计划和信息警戒性的决策培训对信息取样有影响,一定程度上提高了非分享信息的讨论比例,然而这种影响仅发生在任务难度小或适中的情况下。决策培训对信息取样的影响发生在讨论的开始部分,并影响了讨论前的个体偏好;(4)群体结构和决策培训具有交互作用,从而影响了群体讨论的信息取样,群体结构和决策培训都受到任务难度的影响。     

材料规则难度对内隐与外显协同学习的影响

选取两种规则难度的人工语法字母串.采用强分离的实验程序,探索了材料规则难度对内隐学习、内隐与外显的协同学习的影响.结果显示: (1)规则难度较大的限定状态人工语法学习中,内隐学习成绩显著好于外显学习;而在难度较小的双条件语法学习中,外显学习显著好于内隐学习. (2)在两种规则难度的材料学习中,内隐与外显的协同学习成绩均好于单独的内隐或者外显学习,具有优势效应. (3)内隐学习获得的规则知识具有可迁移性.     

知识类别和特点对内隐序列学习的影响

用序列学习中的反应时和错误个数间接测量被试的内隐知识,用再认成绩和预测成绩直接测量被试的外显知识,通过倒转不同的规则探讨了知识类别和特点对内隐序列学习的影响。结果表明：(1)内隐学习和外显学习可能分别依赖于两个独立的学习系统,且互不干扰;(2)当内隐序列学习既包含运动知识又包含概念知识时,知识类别和特点影响被试对序列知识的获得,被试较易获得运动知识;(3)在内隐序列学习中练习的数量也影响被试对序列知识的获得,序列学习是一个动态的过程。
