Syllabus: How Do Children Develop Language and Thought?
Ask what must change for a child to represent something in a new way. Compare Carey’s proposed starting resources and learning mechanism with Siegler’s account of changing strategies, and keep familiar category use distinct from conceptual construction.
A question to consider. What would distinguish learning more number facts within an existing system from acquiring a new understanding of what the count list represents?
Why this reading
Learning can change what a person is able to represent, not only the number of facts available. Carey uses children’s acquisition of number concepts to ask how a richer conceptual system could emerge from earlier resources. The proposal makes the role of language in conceptual change explicit and open to criticism.
Before you read
An approximate quantity representation distinguishes roughly more from less. Individuating objects means keeping track of particular items. Cardinality is how many items a set contains. The successor relation links each whole number to the number one greater. Bootstrapping here is a proposed learning process in which initially partial symbols gain meaning through relations to existing knowledge; it is not a statistical resampling method.
Read for
- Separate the proposed starting representations, the conceptual achievement to be explained, and the mechanism connecting them. What can each starting resource represent?
- Trace the role of learning an ordered count list before fully understanding its meanings. Identify the analogy or inference that is supposed to make a new concept possible.
- Distinguish observations about children’s responses from the stronger theoretical claim that a new representational resource has been constructed. What alternative interpretation would the account need to address?
Consider afterwards
- A child recites a count list but cannot reliably give an adult a requested number of objects. Propose a sequence of observations that could reveal what the words mean to the child and how that understanding changes.
Editorial context
This is a compact theoretical argument about conceptual development, illustrated by number. Its proposed mechanism and claims about early representations are hypotheses, not definitions that settle the issue. Barner’s later discussion examines the explanatory demands of acquiring exact numeral meanings. The account also invites questions about how language-specific and educational experience contribute; it should not be used to rank cultures by the presence of a particular vocabulary. A theory of number learning is not automatically a theory of all conceptual change.
