不相关言语对视觉觉察的影响

前人多在记忆层面探讨不相关言语效应(the Irrelevant Speech Effect, ISE), 而本文选择在意识觉察(conscious awareness)阶段观察这一现象。所有实验均采用视觉掩蔽及听觉输入不相关声音的视听交互方式。实验1在安静、纯音及不相关言语3种听觉背景下让被试对简单图片做视觉觉察判断, 结果发现不相关言语干扰了视觉觉察, 而纯音则未产生干扰。实验2在相同的3种听觉背景下要求被试对复杂图片做视觉觉察判断, 结果同实验1。实验3采用事件相关电位技术, 在同样的3种听觉背景下观察被试对简单图片做视觉觉察判断时的脑电变化, 结果发现不相关言语干扰了视觉觉察负波的形成, 验证了行为学研究的结果。本文结果表明不相干言语在视觉意识觉察阶段就对被试的行为产生了干扰。     

Putting It on the Line: Telephone Counseling for Adolescent Smokers

Adolescent smokers need cessation help, but the question of how best to intervene remains unanswered. This article describes the empirically validated protocol of an established, well‐utilized adolescent telephone counseling program for smoking cessation, tailored to adolescent developmental needs and shown to increase clients' 6‐month prolonged abstinence rate significantly. Clinical issues addressed include client assessment, motivation, self‐efficacy, familial and social support, planning, coping, relapse‐sensitive call scheduling, and self‐image. Counselor training considerations are also discussed.     

学习者生成图解对说明文阅读理解和应用的效果

在112名大学生被试阅读难度不同的两种材料并解答相关的理解题和应用题时,按照阅读时是否要求生成图解与答题时是否允许生成图解两个条件将他们平均分为四个小组,探讨阅读画图与答题画图对被试理解和应用不同难度材料的影响。结果表明,阅读时学习者生成的图解可显著促进对难度较高材料的理解;答题时学习者生成的图解可显著促进对难度较低材料的应用;阅读时是否画图与答题时是否画图对理解和应用所学习材料没有显著交互作用。     

Are people always more risk averse after disasters? Surveys after a heavy snow‐hit and a major earthquake in China in 2008

China suffered both a heavy snow‐hit and a major earthquake in 2008. To investigate the effects of disasters on risky decision making, opportunity samples were obtained by recruiting residents in both devastated and non‐devastated areas. In a survey (Study 1) conducted shortly after the heavy snow‐hit, we found that people were not always more risk averse after a disaster as previous studies had claimed and that they were inclined to approach an option with ‘low probability associated gain’ and to avoid an option with ‘low probability associated loss’. These findings were replicated in a consecutive survey (Study 2) conducted after the Wenchuan earthquake. It was further found that the popularity of both insurance and lottery, which presumably contributed to overweighing of small probabilities, was detected to have been enhanced with substantial exposure to the earthquake disaster. The implications of these findings for risk education and government policy making were discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

当代农民工感知社会支持、自尊和主观幸福感的关系

本研究以600名农民工为被试,采用自编的农民工感知社会支持情景问卷以及修订的自尊量表、农民工主观幸福感问卷,以探讨农民工感知社会支持、自尊与主观幸福感的关系,并考查农民工自尊在其感知社会支持与主观幸福感之间的中介作用。结果表明：（1）高自尊水平农民工的主观幸福感及其各维度、感知社会支持都极其显著地高于低自尊农民工;（2）自尊水平与主观幸福感及各维度、感知社会支持水平之间存在极其显著的正相关关系;（3）感知社会支持、自尊与主观幸福感显著两两正相关;（4）自尊在感知社会支持基础上对主观幸福感及两个维度回归效应显著,为二者之间重要的中介变量。     

整合模型还是占优启发式模型? 从齐当别模型视角进行的检验

实验从齐当别模型的视角,通过对决策过程反应时的考察分别对以累积预期理论(cumulative prospect theory)为代表的整合模型和启发式模型家族的重要成员--占优启发式模型(priority heuristic)--进行检验。结果表明,决策过程反应时并未随着占优启发式模型所假定的决策步骤的增加而变慢;也未随着选项之间整体值差值的变大而变快;模糊决策过程的反应时反而快于风险决策过程的反应时。无论是以累积预期理论为代表的整合模型还是占优启发式模型均不能满意地描述和解释人们的实际决策过程,而齐当别模型则能解释大部分实验结果。文章建议多角度、多指标探讨人们的决策过程,检验、修改、完善,以及建立新的启发式模型或决策过程模型(process model),以增进对人们如何进行风险决策的理解。     

辩证行为疗法的回顾与前瞻

辩证行为疗法(DBT)是最近十几年来兴起的一种主要针对边缘性人格障碍(BPD)的有效治疗方法。就辩证行为疗法的基本理论与治疗模式、治疗阶段与治疗策略进行综述,并介绍了国外最近的临床研究进展,最后对该疗法的应用前景进行了展望。     

言语和非言语信号加工的早期分离——来自ERP研究的证据

利用128导事件相关电位技术,对19名正常被试在言语、峰鸣声和音乐刺激上产生的脑电早期外源性成分N1进行了考察。实验结果发现,在音素条件和蜂鸣声条件下,左侧额叶N1波幅显著高于右侧。偶极子溯源分析发现音素条件和蜂鸣声条件下的偶极子都位于左脑额叶,而音乐条件下的两个偶极子位于右脑额叶。证明范畴属性对信号加工大脑半球优势的影响在加工的早期就开始发挥作用。     

沟通与刻板印象的维持、变化和抑制

沟通提供了维持人类社会行为所必要的信息, 是人类交换信息, 建立并维持相互联系的工具。刻板印象是一种涉及知觉者对某个群体的知识、观念与期望的认知结构。近年来, 研究者们从多个方面探讨了沟通与刻板印象的维持、变化和抑制的关系, 发现群体内沟通, 通过策略性的信息选择和语言偏差, 能够维持刻板印象, 并可能使刻板印象极端化; 而群际沟通, 特别是代理式的群际沟通, 则成为抑制刻板印象的一种可能方法。
