Renewal during functional communication training

Functional communication training (FCT) is one of the most commonly prescribed interventions for the treatment of severe destructive behavior exhibited by individuals with intellectual disabilities. Although highly effective, FCT has been shown to fail in some cases when treatment is introduced into the child's typical environment. Basic and translational research on renewal provides a model for studying the relapse of destructive behavior following successful response to treatment in clinic settings using FCT. In the present study, we evaluated whether relapse of destructive behavior could be attributed to the discriminative control of the home context, which was historically correlated with reinforcement for destructive behavior. We implemented baseline contingencies in the home setting with caregivers acting as interventionists (i.e., Context A). We then implemented FCT in a treatment clinic with trained therapists (i.e., Context B). Finally, we introduced FCT in the home setting with caregivers implementing the treatment procedures (i.e., return to Context A). For three of four participants we observed the relapse of destructive behavior consistent with operant renewal. We discuss the implications of these findings with respect to strategies designed to promote generalization of FCT across settings during the treatment of severe destructive behavior.     

群体情境下儿童的分配公平性

群体情境下儿童的资源分配决策受到群体身份、群体地位和群体规范的影响。在群体因素与公平分配之间, 儿童或坚持公平正义, 或偏向群体利益。这三种群体因素对儿童的分配公平性均造成了影响; 个体因素也会影响群体情境下儿童的分配决策。未来研究应对群体因素多加关注, 通过操控分配情境中的群体信息, 尝试探讨三种群体因素之间的相互作用, 以进一步了解复杂的群体情境下儿童的分配公平性。群体情境下影响分配公平性的个体因素也是需要未来研究逐一验证和讨论的问题。     

中国情境下公共服务动机的理论构建与绩效转换机制

准确把握基层公职人员的公共服务动机是提升工作绩效、完善人力资源管理的重要前提。现有公共服务动机研究忽略了中国情景的特殊性, 对公共服务动机的微观激发机制及其消极绩效影响也关注不足。本研究从中国情景下公共服务动机的概念、核心构成要素、激发机制以及绩效结果入手, 从三个方面系统地构建适合中国场景的公共服务动机理论：第一, 将公共服务动机视为混合动机概念, 基于扎根理论的定性方式识别基层公务员公共服务动机的构成要素与核心内涵, 并据此开发本土化、多维度的公共服务动机量表; 第二, 从微观激发机制出发, 探讨受益人接触、自我倡议、观念反思等机制对个体公共服务动机的激发作用; 第三, 从积极影响和消极影响两个方面探讨公共服务动机与个体公务员行为间的关联及其机理。本研究既响应了国内公共管理学界长期以来发展本土理论的呼声, 亦为政府部门完善公共人事政策提供切实思路和实证依据。     

ERP Evidence for the Rapid Assignment of an (Appropriate) Antecedent to PRO

Event-related brain potentials were recorded while subjects listened to sentences containing a controlled infinitival complement. Subject and object control items were used, both with 2 potential antecedents in the upper clause. Half of the sentences had a gender agreement violation between the null subject of the infinitival complement and an adjective predicated of it. The rapid detection of this anomaly would indicate that the parser had established the coreference relation between the null subject and an antecedent, and that the processor had rapidly consulted verb control information to select the proper antecedent of the null subject. The results showed that for both subject and object control items ungrammatical adjectives elicited a P600 effect. These data imply that the processor has coindexed the null subject with an antecedent, and that the antecedent has been selected on the basis of control information. These results are compatible with parsing models that emphasize the rapid influence of verb-specific information on sentence processing.     

情境对面孔表情识别的影响

长期以来,关于面孔表情识别的研究主要是围绕着面孔本身的结构特征来进行的,但是近年来的研究发现,面孔表情的识别也会受到其所在的情境背景（如语言文字、身体背景、自然与社会场景等）的影响,特别是在识别表情相似的面孔时,情境对面孔表情识别的影响更大。本文首先介绍和分析了近几年关于语言文字、身体动作、自然场景和社会场景等情境影响个体对面孔表情的识别的有关研究;其次,又分析了文化背景、年龄以及焦虑程度等因素对面孔表情识别情境效应的影响;最后,强调了未来的研究应重视研究儿童被试群体、拓展情绪的类别、关注真实生活中的面孔情绪感知等。     

汉语双音节同音词词汇歧义消解过程的研究

使用跨通道词汇判断任务和语义启动技术,两个实验分别考察了孤立状态下和句子语境中汉语双音节同音词意义通达的情况,结果发现(1)在孤立状态下,无论ISI为0毫秒还是-150毫秒,与同音词主要或次要意义有关的探测词都受到了促进;(2)当ISI为0毫秒时,在语境一致的条件下,与同音词主要或次要意义有关的探测词均受到了促进,在语境不一致的条件下,则未发现任何促进效应;(3)当ISI为-150毫秒时,只是在语境一致并且探测词与同音词的主要意义有关的条件下才观察到促进效应。     

中小学生字词再认中场合效应的发展研究

以223名小五、初二、高二学生为被试,探讨对学习项目的加工水平与再认中场合效应的关系以及这种关系的年龄特征。结果表明:(1)当对学习项目进行深加工时,场合因素对三个年级再认效果的影响没有表现出年龄趋势;当对学习项目进行浅加工时,场合因素对小学五年级再认效果的影响显著高于对初二、高二年级的影响,而初二、高二年级的差异不显著;(2)小学五年级学生再认中的场合效应与掩蔽模型的假设一致,初二、高二年级学生的场合效应与加和整体匹配模型的假设一致。
