summaryIn this talk I address the problem of conceptual change in the domain of number. My suggestion, on analogy to the birth of formal semantics in the 1960's, is that characterizing the semantics of early numerical concepts seems impossible if pragmatics is ignored, since children's early numerical representations appear to be incommensurable with their later knowledge of number. I argue that this incommensurability is likely an illusion, however, and that when pragmatic inference is accounted for, number word meanings can be explained by existing representational resources that children use to acquire non-exact quantifiers. To make this case, I examine two candidate conceptual changes. First, I ask whether exactness is unique to number words, and conclude that it is not, but falls out from non-exact lexical meanings shared with quantifiers, plus Gricean quantity implicature. To make this case, I will review evidence that young children can compute sophisticated conversational implicatures, and that behaviors which appear to support true conceptual change are in fact explained by pragmatic inference. Second, I ask whether learning to use counting to label sets involves a conceptual change, and argue that it does not. Instead, learning to count is purely procedural in nature, though it lays the groundwork for learning the inferential roles of number words, and thus for acquiring mathematical knowledge.
