This article focuses on how young children acquire concepts for exact, cardinal numbers. I believe that exact numbers are a conceptual structure that was invented by people, and that most children acquire gradually, over a period of months or years during early childhood. This article reviews studies that explore children’s number knowledge at various points during this acquisition process. Most of these studies were done in my own lab, and assume the theoretical framework proposed by Carey. In this framework, the (...) counting list and the counting routine form a placeholder structure. Over time, the placeholder structure is gradually filled in with meaning to become a conceptual structure that allows the child to represent exact numbers A number system is a socially shared, structured set of symbols that pose a learning challenge for children. But once children have acquired a number system, it allows them to represent information that they had no way of representing before. (shrink)

This paper argues that our folk-psychological expertise is a special case of extended and enculturated cognition where we learn to regulate both our own and others’ thought and action in accord with a wide array of culturally shaped folk-psychological norms. The view has three noteworthy features: it challenges a common assumption that the foundational capacity at work in folk-psychological expertise is one of interpreting behaviour in mentalistic terms, arguing instead that successful mindreading is largely a consequence of successful mindshaping; it (...) argues that our folk-psychological expertise is not only socially scaffolded in development, it continues to be socially supported and maintained in maturity, thereby presenting a radically different picture of what mature folk-psychological competency amounts to; it provides grounds for resisting a recent trend in theoretical explanations of quotidian social interaction that downplays the deployment of sophisticated mentalizing resources in understanding what others are doing.
