汉语句子理解中物体隐含颜色心理模拟的ERPs研究

当前研究采用事件相关电位(ERPs)技术,同时沿用经典的句图匹配范式,考察句子理解中物体典型颜色与非典型颜色的心理加工过程在脑电活动上的反映。实验中被试先阅读句子再判断句子后呈现的图片物体是否在句子中出现过,句子中隐含的物体颜色或是关键物体的典型颜色或是非典型颜色。实验结果发现,典型颜色句子版本下句图不匹配条件比句图匹配条件引发了更大的N400效应;而非典型颜色句子版本下两者N400差异不显著。研究结果表明,人们在汉语句子理解过程中会实时对隐含的物体颜色信息进行心理模拟。并且,句子隐含物体颜色的典型性是造成匹配易化或不匹配易化的关键因素之一。     

自我知觉视角和元知觉视角下能动性评价对自尊的预测作用

本研究探讨自我知觉视角和元知觉视角下社会认知基本维度对自尊的预测作用。研究1中36名被试同时完成自我知觉和元知觉视角下的能动性和社群性评价任务,结果发现仅有自我知觉视角下的能动性评价能预测自尊,元知觉视角下能动性评价对自尊的预测作用被自我知觉视角下的能动性评价所中介;研究2中120名被试完成自我知觉视角评价任务,另120名被试完成元知觉视角评价任务,结果发现无论是自我知觉视角还是元知觉视角,能动性评价都能预测自尊,而社群性评价对自尊没有预测作用,这表明能动性评价能预测个体的自尊。     

聋生心理健康与成就动机、行为方式的相互影响

以苏州市聋生这一特殊群体为研究对象,运用问卷调查和半结构式访谈的方法,探讨其心理健康状况及影响因素。结果发现,聋生的心理健康程度不及正常学生,表现在总分以及躯体症状、焦虑担忧、抑郁三个分量表上的得分均高于正常学生。学业压力、应对方式、内部成就动机和外部成就动机是影响聋生心理健康的重要因素,聋生所感受到的社会支持程度要高于正常学生,聋生的成就动机也高于正常学生,而面对压力,他们的行为应对方式却较多退缩性的。造成这种矛盾的原因是家庭和学校教育中对聋生自强、自立、自理能力培养不到位,助长了聋生因残疾而产生的惰性和依赖性行为,对聋生的心理健康产生了消极影响。社会应提倡更多的正常人学习手语,让聋生有更好的社会交往环境     

负数的空间表征引起的空间注意转移

本研究采用数字线索提示的刺激探测任务, 通过三个实验探讨负数的低水平加工能否,以及怎样引起空间注意的转移。实验一探讨只有负数单独呈现作为线索时能否引起空间注意的转移。结果表明：对负数绝对值大小的加工能引起空间注意的转移。实验二进一步探讨在正数、负数和零混合作为线索时能否引起空间注意的转移。结果表明：对负数数量大小的加工能引起空间注意的转移。实验三再次用正数, 负数和0三种数字混合作为探测刺激前的线索, 但仅对负数和零作为提示线索之后的探测刺激进行反应, 又一次得到了由有效提示线索所引发的对数字数量大小加工引起的空间注意的转移。本研究表明, 对负数的低水平加工可以引起空间注意的转移, 然而, 是对绝对值的加工还是数量大小的加工引起注意转移依赖于共同参与的其它数字加工产生的影响。     

道德虚伪：一种机会主义的适应策略

道德虚伪在个体层面是指人们言行不一, 在人际层面是指人们持有双重标准。心理学家通常从道德动机、认知失调以及精神分析的角度考察道德虚伪。诱发道德虚伪通常会促使个体做出跟他们公开承诺相一致的行为。作为一种机会主义的适应策略, 道德虚伪可能起源于群体适应情境下的自我谋利需要, 带有欺骗他人和自欺的特点。除了情绪、权力等因素之外, 未来研究需要考察自恋、羞耻、社会操纵能力、情商、文化因素对道德虚伪的影响。     

Knowledge of Memory Aging Across the Lifespan

ABSTRACT. The authors examined knowledge of normal and pathological memory aging in a lifespan sample of 198 individuals who ranged in age from 13 to 88 years. Participants completed the Knowledge of Memory Aging Questionnaire (Cherry, Brigman, Hawley, & Reese, 2003). The authors hypothesized that high school students would be less knowledgeable about memory aging issues than college students, middle-aged, and community-dwelling older adults. Consistent with this hypothesis, response accuracy was lower for high school students compared to their older counterparts. Follow-up analyses revealed that high school students’ responses to a subset of questions that tap ageist views of adult cognition were less accurate than the other age groups, implying a response bias toward stereotypical images of memory aging. Implications for research and the design of instructional materials to increase people's knowledge about normative changes in adult cognition are discussed.     

Six-month-olds’ ability to use linguistic cues when interpreting others’ pointing actions

The present research investigated whether six-month-olds who rarely produce pointing actions can detect the object-directedness and communicative function of others’ pointing actions when linguistic information is provided. In Experiment 1, infants were randomly assigned to either a novel-word or emotional-vocalization condition. They were first familiarized with an event in which an actor uttered either a novel label (novel-word condition) or exclamatory expression (emotional-vocalization condition) and then pointed to one of two objects. Next, the positions of the objects were switched. During test trials, each infant watched the new-referent event where the actor pointed to the object to which the actor had not pointed before or the old-referent event where the actor pointed to the old object in its new location. Infants in the novel-word condition looked reliably longer at the new-referent event than at the old-referent event, suggesting that they encoded the object-directedness of the actor’s point. In contrast, infants in the emotional-vocalization condition showed roughly equal looking times to the two events. To further examine infants’ understanding of the communicative aspect of an actor’s point using a different communicative context, Experiment 2 used an identical procedure to the novel-word condition in Experiment 1, except there was only one object present during the familiarization trials. When the familiarization trials did not include a contrasting object, we found that the communicative intention of the actor’s point could be ambiguous. The infants showed roughly equal looking times during the two test events. The current research suggests that six-month-olds understand the object-directedness and communicative intention of others’ pointing when presented with a label, but not when presented with an emotional non-speech vocalization.     

Conditions for the clean slate effect after success or failure

The act of physically cleaning one’s hands may reduce the impact of past experiences, termed clean-slate effect. Cleaning was found to affect negative, neutral, and mildly positive states. We extend this influence to success, a self-serving state. We manipulated success vs. failure and measured changes in optimism (Experiment 1) or self-esteem (Experiment 2). Moreover, we examined boundary conditions for the clean-slate effect. Experiment 1 indicates that the influence of performance on optimism diminishes if participants knew (compared to did not know) they were cleaning their hands. Experiment 2 indicates that the influence of performance on self-esteem diminishes if participants cleaned themselves (compared to an object). These results suggest that the clean-slate effect requires both awareness and self-reference of the cleaning act. Thus, the clean-slate effect seems to depend on both conscious inferences and automatic processes. A meta-analysis across the experiments confirms a moderate-sized clean-slate effect.
