注意资源、学习方式与年龄因素对协作抑制的影响

本研究在前人研究的基础上,试图探讨不同编码因素对协作抑制效应的制约作用,从协作抑制角度为挖掘集体记忆的作用机制提供证据。实验1结果发现,集中注意条件下,出现协作抑制;分配注意条件下,协作抑制消失。说明学习时注意资源的投入程度,对协作抑制有影响。实验2结果发现不同的学习方式对协作抑制的影响在不同年龄被试身上表现不同。本研究将视角聚焦于编码因素,研究结果证实,协作抑制受到不同编码因素的制约,此外,本结果亦为协作抑制的提取策略破坏假说提供了新的证据。     

Frustration and successful vs. Unsuccessful aggression: A test of Berkowitz' completion hypothesis

Author experiment using a modified version of the Buss' aggression paradigm tested Berkowitz' completion hypothesis, which states unsuccessful aggressive attempts at the frustrator serve as further frustration and intensify aggression. Testing was done by varying the number of successful aggressive attempts for different experimental groups. The experiment indicated first a positive relationship between subjective levels of frustration and aggression, which supports a general frustration-aggression hypothesis, and second that unsuccessful aggressive attempts lead to increased aggression in terms of shock intensity. This was interpreted as supportive of Berkowitz' completion hypothesis, although alternative interpretations in terms of cognitive and behavioral strategies cannot be excluded.     

不同情感强度正性生活事件的情感和行为反应:多模型的检验和整合

3个实验探讨情感强度不同正性生活事件对个体情感和行为反应的影响。发现:(1)面对复合正性生活事件(1高正+1低正),个体会感觉比面对1个单独的高正性情感强度事件的正性感受更低,出现平均效应,2个正性生活事件不如1个好;进一步研究发现:(2)当复合正性生活事件为异类时,出现平均效应;当事件为同类时,出现累加效应;(3)当复合正性生活事件有明显的时间特点时,个体加工符合峰-终定律的解释。     

水平空间与情绪效价联结效应的产生机制

采用词汇效价判断任务,考察水平空间与情绪效价联合效应的产生机制。实验1在被试双手正常放置条件下考察了词汇效价与水平空间联结效应的存在;实验2则要求被试双手交叉放置,以考察当反应手和反应键的空间信息冲突时水平空间与情感效价的关联现象;实验3则进一步考排除反应手的参与,以考察口头报告的反应方式是否对两者的联结效应产生影响。结果表明,不同反应方式下均存在空间情感效价的联结,且此联结更多是反应选择极性编码的结果。     

Communicative functions of directional verbal probabilities: Speaker’s choice,listener’s inference,and reference points

Verbal probabilities have directional communicative functions, and most can be categorized as positive (e.g., “it is likely”) or negative (e.g., “it is doubtful”). We examined the communicative functions of verbal probabilities based on the reference point hypothesis According to this hypothesis, listeners are sensitive to and can infer a speaker’s reference points based on the speaker’s selected directionality. In four experiments (two of which examined speakers’ choice of directionality and two of which examined listeners’ inferences about a speaker’s reference point), we found that listeners could make inferences about speakers’ reference points based on the stated directionality of verbal probability. Thus, the directionality of verbal probabilities serves the communicative function of conveying information about a speaker’s reference point.     

范围假设解释大学生性别刻板印象表征的适用性*

通过任务助长实验范式考察范围假设对于某一熟悉群体刻板化特质判断的适用性。研究结果表明当大学生对于某一熟悉群体的刻板印象的抽象表征被激活时,违反刻板印象的样例表征也得到激活,用以限定抽象表征的适用范围。研究结果支持范围假设,即当一个抽象概念从语义记忆中被提取时,与抽象概念相冲突的情景记忆也被提取,以用来限定抽象概念的适用范围。     

专家记忆优势效应理论的比较

依据专家记忆优势效应三个主要理论 (即模板理论、长时工作记忆理论和限制调节理论 )的不同特点选取变量 ,以中国象棋为实验材料 ,采用 2× 2× 2× 2混合设计 ,对三个理论进行检验比较。研究发现 :(1)被试在记忆棋局条件下的包含测验成绩 ,优于选择着法条件下的 ;(2 )棋局与棋手水平之间不存在显著的交互作用 ;(3)棋局与提取时的意识水平之间存在显著的交互作用 ,对局中的外显效应大于排局中的外显效应 ,而棋局的内隐效应则无显著差异。上述结果表明 ,相对而言 ,长时工作记忆理论能够对专家记忆优势效应作出合理的解释     

婚姻冲突与儿童问题行为关系研究的理论进展

大量研究指出婚姻冲突与儿童问题行为紧密相关,但在二者关系的解释上有不同观点。其中代表性的理论有社会学习理论、间接作用观点、认知-背景理论和情绪安全假设等。文中详细介绍了4个理论的基本观点并分析了其优缺点。综合这些理论,作者在理解婚姻冲突和儿童问题行为时应该坚持如下3个观点:第一,系统和生态的观点;第二,主客体相互作用的观点;第三,情感和认知并重的观点。     

Content difference between normal and abnormal obsessions

Although it has long been thought that experiencing an obsession is a psychiatric symptom, more recent literature, has seen the normalisation of obsessions and other presumably clinical phenomena. That is, not only people suffering from psychiatric disorders experience obsessions but non-clinical individuals also do so. Furthermore, it has been argued that such normal obsessions are very similar to abnormal ones, in terms of content. However, in the present study, evidence was obtained indicating that normal and abnormal obsessions do differ in content. A sample of 133 healthy undergraduates was given a list of 70 obsessions, with some originating from obsessive-compulsive disorder (OCD) patients, and others stemming from healthy volunteers. Participants were asked to indicate whether they had ever experienced these obsessions. Participants endorsed significantly more normal than abnormal obsessions, suggesting that the two kinds of obsessions do differ from each other. In addition, the experience of clinical obsessions was more strongly associated with scores on a measure of OCD symptoms, than was the experience of normal obsessions.
