The robustness of learning through overhearing.

Two studies examined the robustness of vocabulary learning through overhearing by testing 48 2-year-olds in contexts in which a potentially distracting activity was present (Studies 1 and 2) and in which the novel word was embedded in a directive rather than a labeling statement (Study 2). The children were equally good at learning a novel object label when there was no distracting activity as when there was. They were also able to learn the word when the object was not explicitly labeled. These findings suggest that young children are keen observers of third-party interactions and that their linguistic input consists of more than just speech directly addressed to them.

Learning antecedents for anaphoric one.

Lidz et al. [Lidz, J., Waxman, S., & Freedman, J. (2003). What infants know about syntax but couldn't have learned: Experimental evidence for syntactic structure at 18 months. Cognition, 89, B65-B73.] claim experimental substantiation of an argument from the poverty of the stimulus, in the sense of Pullum and Scholz [Linguist. Rev. 19 (2002) 9]. They cite a specific feature of English--the assignment of appropriate antecedents for anaphoric one--that cannot possibly be learned from experience because the evidence needed is found only in utterances of a type too rare to be encountered. Their argument involves three empirical claims. In this note we dispute all three.

Two-year-olds' sensitivity to speakers' intent: an alternative account of Samuelson and Smith.

Seventy-two 2-year-olds participated in a study designed to test two competing accounts of the effect of contextual change on children's ability to learn a word for an object. The mechanistic account hypothesizes that any change in context that highlights a target object will lead to word learning; the social-pragmatic account maintains that a change in context must be perceived as relevant to the speaker's communicative intentions. Consistent with the latter account, we found that children learned the word when a change in context was intentional but not when it was accidental, and children failed to learn the word for the highlighted object when a speaker naive to the preceding context named the object.

Relevance and early word learning.

Several theorists have proposed that children may interpret an ambiguous word by attending to the dimension that is most relevant in the immediate discourse context. The current study offers a direct test of this hypothesis. Children aged 2;6 and 3;4 (N = 24 in each group) were presented with a novel object with an unusual shape and texture and were told 'This is a dacky one'. In the Shape-Relevant condition, two other objects' shapes were described before the target object was labelled ('This is a round one; this is a square one'). In the Texture-Relevant condition, two preceding objects' textures were described ('This is a smooth one; this is a fuzzy one'). Subsequent comprehension tests indicated that, in extending the novel adjective to other exemplars, children attended to the dimension that was most relevant to the preceding discourse context.
