Speech-associated gestures, Broca’s area, and the human mirror system

Speech-associated gestures are hand and arm movements that not only convey semantic information to listeners but are themselves actions. Broca’s area has been assumed to play an important role both in semantic retrieval or selection (as part of a language comprehension system) and in action recognition (as part of a “mirror” or “observation–execution matching” system). We asked whether the role that Broca’s area plays in processing speech-associated gestures is consistent with the semantic retrieval/selection account (predicting relatively weak interactions between Broca’s area and other cortical areas because the meaningful information that speech-associated gestures convey reduces semantic ambiguity and thus reduces the need for semantic retrieval/selection) or the action recognition account (predicting strong interactions between Broca’s area and other cortical areas because speech-associated gestures are goal-direct actions that are “mirrored”). We compared the functional connectivity of Broca’s area with other cortical areas when participants listened to stories while watching meaningful speech-associated gestures, speech-irrelevant self-grooming hand movements, or no hand movements. A network analysis of neuroimaging data showed that interactions involving Broca’s area and other cortical areas were weakest when spoken language was accompanied by meaningful speech-associated gestures, and strongest when spoken language was accompanied by self-grooming hand movements or by no hand movements at all. Results are discussed with respect to the role that the human mirror system plays in processing speech-associated movements.     

Young children's reports of when learning occurred

This study investigated young children's reports of when learning occurred. A total of 96 4-, 5-, and 6-year-olds were recruited from suburban preschools and elementary schools. The children learned an animal fact and a body movement. A week later, children learned another animal fact and another body movement and then answered questions about when the different learning events occurred. Responses of children who responded correctly to control questions about time supported the hypothesis that temporal distance questions would elicit more correct responses than would temporal location questions. Partial support was also found for the hypothesis that behavior learning would generate more correct reports than would fact learning. Implications for characterizations of children's developing understanding of knowledge and for applications of those characterizations in education and eyewitness testimony are discussed.     

Spatial and linguistic aspects of visual imagery in sentence comprehension

There is mounting evidence that language comprehension involves the activation of mental imagery of the content of utterances ( Barsalou, 1999 ; Bergen, Chang, & Narayan, 2004 ; Bergen, Narayan, & Feldman, 2003 ; Narayan, Bergen, & Weinberg, 2004 ; Richardson, Spivey, McRae, & Barsalou, 2003 ; Stanfield & Zwaan, 2001 ; Zwaan, Stanfield, & Yaxley, 2002 ). This imagery can have motor or perceptual content. Three main questions about the process remain under‐explored, however. First, are lexical associations with perception or motion sufficient to yield mental simulation, or is the integration of lexical semantics into larger structures, like sentences, necessary? Second, what linguistic elements (e.g., verbs, nouns, etc.) trigger mental simulations? Third, how detailed are the visual simulations that are performed? A series of behavioral experiments address these questions, using a visual object categorization task to investigate whether up‐ or down‐related language selectively interferes with visual processing in the same part of the visual field (following Richardson et al., 2003 ). The results demonstrate that either subject nouns or main verbs can trigger visual imagery, but only when used in literal sentences about real space—metaphorical language does not yield significant effects—which implies that it is the comprehension of the sentence as a whole and not simply lexical associations that yields imagery effects. These studies also show that the evoked imagery contains detail as to the part of the visual field where the described scene would take place.     

Contextualizing counterintuitiveness: how context affects comprehension and memorability of counterintuitive concepts

A number of anthropologists have argued that religious concepts are minimally counterintuitive and that this gives them mnemic advantages. This paper addresses the question of why people have the memory architecture that results in such concepts being more memorable than other types of concepts by pointing out the benefits of a memory structure that leads to better recall for minimally counterintuitive concepts and by showing how such benefits emerge in the real-time processing of comprehending narratives such as folk tales. This model suggests that memorability is not an inherent property of a concept; rather it is a property of the concept, the context in which the concept is presented, and the background knowledge that the comprehendor possesses about the concept. The model predicts how memorability of a concept should change if the context containing the concept were changed. The paper also presents the results of experiments carried out to test these predictions.     

"以易释史"——邵雍咏史诗的一大特征

邵雍是文学家、史学家、易学家,他的咏史诗则是他文史哲研究领域交叉的产物,他的咏史诗表现出了“以易释史”的特点,具体表现为“履霜冰至”与“否极泰来”的思想,“恩患防豫”与“知几如神”的思想,“顺动致豫”与“吉凶由人”的思想和“各行其位”与“时行时止”的思想等四个方面。这是研究他的思想的一个较好的切入点。     

What’s Wrong with Motive Manipulation?

Consider manipulation in which one agent, avoiding force, threat, or fraud mobilizes some non-concern motive of another so as to induce this other to behave or move differently than she would otherwise have behaved or moved, given her circumstances and her initial ranking of concerns. As an instance, imagine that I get us to miss the opening of a play that I have grudgingly agreed to attend by engaging your sublimated compulsive tendency to check the stove when we are halfway to the theatre. Such motive manipulation is, I take it, widely regarded as morally worrisome. If it really is morally worrisome, then we should be able to explain adequately why it is so. But existing condemnations of manipulation come up short in this regard. In this paper, I develop and defend a more plausible account of the moral status of this phenomenon.

两宋史事易学的演变与发展特征

援史释《易》成为宋儒解《易》的常用方式,虽然此种注《易》方式并不始于宋代,但大量用史在宋代易学阐释中表现的尤为突出。究其原因,当与宋代儒学复兴、史学发展以及宋代士人的政治观念有着密切的联系。北宋与南宋的史事易学又呈现出明显的不同,北宋援引史事是出于解说义理的需要,而南宋则用史事解证卦爻辞,直接将《周易》视为一部极具历史借鉴及指导意义的经典。南宋卦卦有史的《周易》阐释并不是一朝一夕形成的,而是北宋援引史事以证易理的继承与发展。     

冯友兰先生的《中国哲学史》:"同情之了解"与新儒学

冯友兰先生先以中国哲学史家名于世。两卷本《中国哲学史》是其成名的代表作。《中国哲学史》有很多特点,其中最主要的即是"同情之了解"与"新儒学"。"同情之了解"不仅是冯先生成功写作《中国哲学史》的原则和方法,而且也是我们今后弘扬中国优秀传统文化所不可或缺的原则与方法。冯先生后来又成了一位著名的新儒家。作为中国现代学术思潮中新儒家的一位典型代表,冯先生本人以及一般论者都公认为应以其"贞元六书"的"新理学"哲学体系为代表。文章赞同这个共识,但想补充一点,即广而言之,似乎也可以包括冯先生所著的两卷本《中国哲学史》在内。文章从其目录、内容、审查、批评、自觉与自白和"贞元六书"多方面进行了探索与论述。     

有限理性存在者的公民伦理——兼论康德《历史理性批判文集》的公民伦理思想

本文力图把康德的公民伦理思想置于其历史理性的理论框架之中来思考其限度及趋向。在康德历史理性的言说中,公民在康德那里作为“有限的理性存在者”,它是自我作为有限存在者“并非无拘”。康德对于用“有限理性存在者”来对其公民伦理思想进行限定,一方面基于康德公民伦理思想是道德形而上学的实践理性理论,另一方面出于他对卢梭的法权哲学原则的呼应。从价值趋向、交往结构、制度规范、内在德性、权利属性、外在环境等方面对康德的公民伦理思想展开分析,可以察知康德公民伦理思想的趋向也体现为世界公民状态。     

Let’s get it together: Infants generate visual predictions based on collaborative goals

Infants engage in social interactions that include multiple partners from very early in development. A growing body of research shows that infants visually predict the outcomes of an individual’s intentional actions, such as a person reaching towards an object (e.g., Krogh-Jespersen & Woodward, 2014), and even show sophistication in their predictions regarding failed actions (e.g., Brandone, Horwitz, Aslin, & Wellman, 2014). Less is known about infants’ understanding of actions involving more than one individual (e.g., collaborative actions), which require representing each partners’ actions in light of the shared goal. Using eye-tracking, Study 1 examined whether 14-month-old infants visually predict the actions of an individual based on her previously shared goal. Infants viewed videos of two women engaged in either a collaborative or noncollaborative interaction. At test, only one woman was present and infants’ visual predictions regarding her future actions were measured. Fourteen-month-olds anticipated an individual’s future actions based on her past collaborative behavior. Study 2 revealed that 11-month-old infants only visually predict higher-order shared goals after engaging in a collaborative intervention. Together, our results indicate that by the second year after birth, infants perceive others’ collaborative actions as structured by shared goals and that active engagement in collaboration strengthens this understanding in young infants.
