人造物概念的表征：功能、意图和目的论的解释

以概念结构研究从“相似”到“解释”的理论转向为背景,评述人造物领域的“意图-历史论”（Bloom, 1996）,提出人造物概念结构中自上而下的约束是来自“使用目的”而不是“设计意图”。分析近期报告的大量实验,最后提出人造物概念表征的“基于使用的目的论”的解释模式和人造物归类的双重目标模型。     

外部攻击型和关系攻击型初中生执行功能的研究

本研究采用数字STROOP、局部-整体图形转换和色点位置刷新三种研究范式检测了40名攻击性初中生的抑制控制、任务转换和信息刷新三种执行功能的特点。研究结果表明,攻击性初中生的抑制控制能力、任务转换能力和信息刷新能力均差于非攻击性初中生。外部攻击型初中生的抑制控制能力、任务转换能力和信息刷新能力均差于非攻击性初中生。而关系攻击型初中生与非攻击性初中生和外部攻击型初中生在执行功能的三种成分上均不存在显著差异,其执行功能水平可能介于非攻击性初中生和外部攻击初中生之间。     

Association of television violence exposure with executive functioning and white matter volume in young adult males

Prior research has indicated that self-reported violent media exposure is associated with poorer performance on some neuropsychological tests in adolescents. This study aimed to examine the relationship of executive functioning to violent television viewing in healthy young adult males and examine how brain structure is associated with media exposure measures. Sixty-five healthy adult males (ages 18–29) with minimal video game experience estimated their television viewing habits over the past year and, during the subsequent week, recorded television viewing time and characteristics in a daily media diary. Participants then completed a battery of neuropsychological laboratory tests quantifying executive functions and underwent a magnetic resonance imaging (MRI) scan. Aggregate measures of executive functioning were not associated with measures of overall television viewing (any content type) during the past week or year. However, the amount of television viewing of violent content only, as indicated by both past-year and daily diary measures, was associated with poorer scores on an aggregate score of inhibition, interference control and attention, with no relationship to a composite working memory score. In addition, violent television exposure, as measured with daily media diaries, was associated with reduced frontoparietal white matter volume. Future longitudinal work is necessary to resolve whether individuals with poor executive function and slower white matter growth are more drawn to violent programming, or if extensive media violence exposure modifies cognitive control mechanisms mediated primarily via prefrontal cortex. Impaired inhibitory mechanisms may be related to reported increases in aggression with higher media violence exposure.     

时间贴现的性质与脑机制

时间贴现是指个人对事件的价值量估计随着时间的流逝而下降的心理现象,它是行为选择理论的一个重要组成部分。着重介绍了时间贴现的数学模型（指数模型、双曲线模型族、非双曲线模型）、时间贴现现象和概率贴现现象的联系、延迟兑现与提前兑现时间贴现不对称现象及其理论解释,还讨论了时间贴现现象的神经机制研究。提出了时间贴现未来研究的几个主要问题     

Executive functions predict conceptual learning of science

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.     

人格结构的动态分析

为了动态化地分析人格的结构。研究一采用个体性自由命名描述法考察人格的动态内容。１５０名大学生分别用１０个词描述实际的自我、理想的自我、应该的自我。词频统计反映了不同自我的内容特点。研究二采用常模化限定性描述法考察人格的结构特点,用研究珠高频词制成实际、理想、应该的自我词表。２００名大学生用７点量表分别评定各词表中的每个词适合描述相应的自我的程度。结果表明,实际的自我有５个因素,解释４７．１％的变异     

侗歌经验对侗族中学生执行功能的影响

音乐训练对认知能力具有广泛的促进效应。本研究结合执行功能的三个成分(抑制控制、工作记忆和认知灵活性), 在我国民族音乐背景下, 匹配实验任务的视觉和听觉形式, 探讨侗歌经验对侗族中学生执行功能的影响。结果表明, 侗歌组被试在抑制能力和刷新能力上显著好于侗族非侗歌组被试和汉族被试, 这一优势在视觉任务中和听觉任务中均存在, 说明侗歌经验产生的认知优势具有跨感觉通道的普遍性。侗歌组被试和侗族非侗歌组被试的转换能力差异不显著。侗族非侗歌组被试的抑制能力和转换能力好于汉族被试, 这体现了语言和音乐的交互作用。     

The effect of shame on anger at others: awareness of the emotion-causing events matters

Numerous studies have found that shame increases individuals’ anger at others. However, according to recent theories about the social function of shame and anger at others, it is possible that shame controls individuals’ anger at others in specific conditions. We replicated previous findings that shame increased individuals’ anger at others’ unfairness, when others were not aware of the individual’s experience of shameful events. We also found for the first time that shame controlled or even decreased individuals’ anger at others’ unfairness, when others were aware of the individual’s experience of shameful events. The results were consistent when shame was induced by either a recall paradigm or an imagination paradigm, and in either the ultimatum game or the dictator game. This suggests that shame strategically controls individuals’ anger at others to demonstrate that they are willing to benefit others, when facing the risk of social exclusion. Our findings highlight the interpersonal function of shame and deepen the understanding of the relationship between shame and anger at others.
