Interpersonal Understanding Fuels Knowledge Acquisition

Beginning in infancy, humans acquire knowledge at a pace far outstripping that found in any other species. Recent evidence indicates that interpersonal understanding—in particular, skill at inferring others' intentions—plays a pivotal role in this achievement. Infants as young as 12 to 18 months actively utilize clues to others' intentions to guide their interpretation of language, emotion, and action more generally. In the language domain, for example, on hearing a new word, infants spontaneously check the speaker for intentional clues such as gaze direction, emotional expression, gestures, and body posture, and interpret the word in light of such information. By capitalizing on information about intentions, infants are able to avoid a wide range of potential errors, and to quickly learn relevant new skills. Current research is exploring the origins and developmental course of such early-emerging interpersonal skill, ultimately with an eye to understanding how disruptions in such abilities affect children's cognitive and social development.     

Metacognitive Development

Traditional developmental research in memory and reasoning, as well as current investigations in such disparate areas as theory of mind, epistemological understanding, knowledge acquisition, and problem solving, share the need to invoke a meta-level of cognition in explaining their respective phenomena. The increasingly influential construct of metacognition can be conceptualized in a developmental framework. Young children's dawning awareness of mental functions lies at one end of a developmental progression that eventuates in complex metaknowing capabilities that many adults do not master. During its extended developmental course, metacognition becomes more explicit, powerful, and effective, as it comes to operate increasingly under the individual's conscious control. Enhancing (a) metacognitive awareness of what one believes and how one knows and (b) metastrategic control in application of the strategies that process new information is an important developmental and educational goal.     

学习策略与程序性知识迁移关系的研究

本研究以学习者拥有领域知识的水平差异为基点 ,结合元认知监控手段 ,考察学习策略与程序性知识迁移之间的关系。结果表明 :(1 )以揭发意义或价值、建立新旧知识信息间实质性联结的解释策略对拥有高、低领域知识组的被试具有明显促进问题解决的作用 ;而以相似性为基础的练习策略往往在学生头脑中建立的是新旧知识间表面特征的联结 ,因而程序化技能的迁移范围不如前者。 (2 )在运用获得的认知技能碰到阻碍时 ,解释策略不仅使高知组被试能够突破无关变量的影响 ,而且也在一定程度上弥补低知组被试掌握的规则缺陷。     

论《尘埃落定》中的道家文化蕴含

《尘埃落定》是藏族作家阿来的作品,长期以来人们对它的解读,往往从藏民族民间文化和宗教文化角度切入,其实如果我们把作家的文人身份和作品中弘扬的人文精神结合起来研读,就会发现在文本中有着浓郁的道家文化身影。     

21世纪医学教育的知识结构初探

在知识爆炸的今天,个人全面系统掌握医学基础知识只能是一个幻想,新世纪要求有关教育知识结构的变革。继续延用经典医学学科多平层型知识结构进行21世纪医学教育已不适应,可满足需求的应是以可持续发展的新知识为核心的核心－壳层型新知识结构。目前似应以细胞知识为核心重组医学教育知识结构体系,按应用基础、临床等知识壳层对冗杂的经典学科知识进行精炼与重组。     

语义知识神经表征的fMRI研究：通道特异性或类别特异性？

在同一实验中同时考虑类别与通道二个因素,并采用典型的语义提取任务应用功能磁共振成像技术探讨了语义知识的神经基础,结果发现不同类型的语义知识的脑激活模式（含左梭形回的激活）无论在范围还是强度上存在很大的相似性;而且,在严格的统计阈值下,不存在通道或是类别特异性激活的脑区。结果提示语义知识的神经表征分布于整个大脑皮层;在提取物体语义知识时都会同时激活该物体的视觉表象。另外,研究观察到的语义提取过程中BA9区的激活进一步证实并扩展了关于“汉语和表音文字在皮层组织上存在重要差异的观点”。     

The role of emotion knowledge in the links between shyness and children's socio‐emotional functioning at preschool

The present study investigated the potential protective role of components of emotion knowledge (i.e., emotion recognition, situation knowledge) in the links between young children's shyness and indices of socio‐emotional functioning. Participants were n = 163 children (82 boys and 81 girls) aged 23–77 months (M = 53.29, SD = 14.48), recruited from preschools in Italy. Parents provided ratings of child shyness and teachers rated children's socio‐emotional functioning at preschool (i.e., social competence, anxiety‐withdrawal, peer rejection). Children were also interviewed to assess their abilities to recognize facial emotional expressions and identify situations that affect emotions. Among the results, shyness was positively related to anxiety‐withdrawal and peer rejection. In addition, emotion recognition was found to significantly moderate the links between shyness and preschool socio‐emotional functioning, appearing to serve a buffering role. For example, at lower levels of emotion recognition, shyness was positively associated with both anxiety‐withdrawal and rejection by peers, but at higher levels of emotion recognition, these associations were attenuated. Results are discussed in terms of the protective role of emotion recognition in promoting shy children's positive socio‐emotional functioning within the classroom context.     

Googling Politics: How Offloading Affects Voting and Political Knowledge

Studies suggest that individuals are less likely to process information they can easily look up. Instead of committing information to memory, they rely on the Internet to store information for them—a phenomenon known as “offloading.” We examine the effects of offloading on political knowledge and voting behavior. Using data from a 10-wave panel experiment designed to study information processing in two distinct information environments, we demonstrate that people whose environment is conducive to offloading learn more during an election campaign than individuals whose information environment is not conducive to offloading, even though they look at less information during the campaign. Individuals in the offloading condition also make better vote choices despite examining less information. These results suggest that offloading reduces cognitive load, thereby freeing up processing space in working memory, which can increase learning of information that is accessed, and improve decision-making.     

How anxiety induces verbal hallucinations

Verbal hallucinations are often associated with pronounced feelings of anxiety, and it has also been suggested that anxiety somehow triggers them. In this paper, we offer a phenomenological or ‘personal-level’ account of how it does so. We show how anxious anticipation of one’s own thought contents can generate an experience of their being ‘alien’. It does so by making an experience of thinking more like one of perceiving, resulting in an unfamiliar kind of intentional state. This accounts for a substantial subset of verbal hallucinations, which are experienced as falling within one’s psychological boundaries and lacking in auditory qualities.     

Categorization as causal reasoning⋆

A theory of categorization is presented in which knowledge of causal relationships between category features is represented in terms of asymmetric and probabilistic causal mechanisms. According to causal‐model theory, objects are classified as category members to the extent they are likely to have been generated or produced by those mechanisms. The empirical results confirmed that participants rated exemplars good category members to the extent their features manifested the expectations that causal knowledge induces, such as correlations between feature pairs that are directly connected by causal relationships. These expectations also included sensitivity to higher‐order feature interactions that emerge from the asymmetries inherent in causal relationships. Quantitative fits of causal‐model theory were superior to those obtained with extensions to traditional similarity‐based models that represent causal knowledge either as higher‐order relational features or “prior exemplars” stored in memory.
