Co‐development of child‐mother gestures over the second and the third years

This study looks at whether there is a relationship between mother and infant gesture production. Specifically, it addresses the extent of articulation in the maternal gesture repertoire and how closely it supports the infant production of gestures. Eight Spanish mothers and their 1‐ and 2‐year‐old babies were studied during 1 year of observations. Maternal and child verbal production, gestures and actions were recorded at their homes on five occasions while performing daily routines. Results indicated that mother and child deictic gestures (pointing and instrumental) and representational gestures (symbolic and social) were very similar at each age group and did not decline across groups. Overall, deictic gestures were more frequent than representational gestures. Maternal adaptation to developmental changes is specific for gesturing but not for acting. Maternal and child speech were related positively to mother and child pointing and representational gestures, and negatively to mother and child instrumental gestures. Mother and child instrumental gestures were positively related to action production, after maternal and child speech was partialled out. Thus, language plays an important role for dyadic communicative activities (gesture–gesture relations) but not for dyadic motor activities (gesture–action relations). Finally, a comparison of the growth curves across sessions showed a closer correspondence for mother–child deictic gestures than for representational gestures. Overall, the results point to the existence of an articulated maternal gesture input that closely supports the child gesture production. Copyright © 2006 John Wiley & Sons, Ltd.     

Maternal beliefs concerning young children's private speech

The goal of this study was to understand maternal reports, beliefs, and attitudes about their young children's use of private speech. Mothers of 48 children between the ages of 3 and 5 participated in a semi‐structured interview in which they reported on the frequency and context of their child's use of private speech, maternal responses toward such speech use in children, and beliefs about the utility of such speech for children. Interviews were transcribed and responses coded. Mothers also completed surveys on children's self control and parenting style. Results indicated that practically all parents reported that their child engaged in private speech and that such speech was more likely to appear during fantasy play than during problem‐solving activities. Parents varied in their personal responses to children's self talk and, as a group, do not appear to actively discourage or encourage its use. Ignoring/allowing child private speech use was common and this response was positively associated with authoritative parenting. Parental reports of the frequency with which their child talks to himself were negatively associated with parental reports of children's self‐control. Crib speech, or bedtime monologue, was reported to be very common and was negatively associated with children's self‐control and positively associated with children's private speech use. Parents were uniformly positive in their belief that private speech serves important functions and that it helps young children during task activities. Copyright © 2006 John Wiley & Sons, Ltd.     

Overcoming the myth of the mental

Can we accept John McDowell’s Kantian claim that perception is conceptual “all the way out,” thereby denying the more basic perceptual capacities we seem to share with prelinguistic infants and higher animals? More generally, can philosophers successfully describe the conceptual upper floors of the edifice of knowledge while ignoring the embodied coping going on on the ground floor? I argue that we shouldn’t leave the conceptual component of our lives hanging in midair and suggest how philosophers who want to understand knowledge and action can profit from a phenomenological analysis of the nonconceptual embodied coping skills we share with animals and infants, as well as the nonconceptual immediate intuitive understanding exhibited by experts.

The power of powerless speech: The effects of speech style and task interdependence on status conferral

Two studies examine the effects of speech styles and task interdependence on status conferral judgments. In both studies, participants were exposed to an individual who used either a powerful or powerless speech style in a low or high task interdependence group, and made judgments about the amount of status to confer to the individual. When task interdependence was low, participants conferred more status to powerful speakers, whereas when interdependence was high, participants conferred more status to powerless speakers. Furthermore, Study 2 demonstrated that speech styles influenced trait inferences about the speaker (agency and communality), but these traits were weighted differently in status conferral judgments across groups. These findings provide insight into both the relationship between observed behaviors and status positions and the decision process underlying status conferral judgments.     

The Social Nature of Perception and Action

ABSTRACT— Humans engage in a wide range of social activities. Previous research has focused on the role of higher cognitive functions, such as mentalizing (the ability to infer others' mental states) and language processing, in social exchange. This article reviews recent studies on action perception and joint action suggesting that basic perception–action links are crucial for many social interactions. Mapping perceived actions to one's own action repertoire enables direct understanding of others' actions and supports action identification. Joint action relies on shared action representations and involves modeling of others' performance in relation to one's own. Taking the social nature of perception and action seriously not only contributes to the understanding of dedicated social processes but has the potential to create a new perspective on the individual mind and brain.     

On additivity of duration reproduction functions

In the present paper properties of theoretical response functions in the duration reproduction task (drt) are studied. If the drt response is to be interpreted as the measure of a temporal duration elapsed in the past, the reproduction function (rf) must be additively measuring. The additivity property is defined for bivariate rfs, taking into account the delay between retention and reproduction. The requirement that an rf be additively measuring leads to a system of two functional equations, which are solved by (i) linear functions of time, or (ii) functions of the form yielded by the ‘dual klepsydra model’ of duration reproduction [Wackermann, J., & Ehm, W. (2006). The klepsydra model of internal time representation and time reproduction. Journal of Theoretical Biology, 239, 482-493]. This result supports the outstanding rôle of the ‘klepsydraic reproduction function’ (krf) in models of internal representation and reproduction of temporal durations.     

双语言语产生中的词汇提取机制

文章主要介绍了双语言语产生中词汇提取机制的两种理论：非特定语言提取的理论和特定语言提取的理论。重点围绕着双语言语产生中词汇提取的一个关键问题,即非目标语言的词汇是否对目标语言的词汇提取形成竞争或者干扰详细地论述了二者的理论分歧,非特定语言提取的理论认为非目标语言的词汇会对目标语言的词汇提取形成竞争,而特定语言提取的理论认为不会形成竞争。文章最后介绍了双语言语产生中词汇提取机制的最新研究趋势,表明了非特定语言提取的理论和特定语言提取的理论逐步走向融和
