Two experiments investigated 4-year-olds' use of descriptive sentences to learn non-obvious properties of unfamiliar kinds. Novel creatures were described using generic or nongeneric sentences (e.g., "These are pagons. Pagons/These pagons are friendly"). Children's willingness to extend the described property to a new category member was then…

Describes a connectionist model, using a simple recurrent network trained on a phoneme prediction task, that accounts for the child's ability to identify word boundaries. The model shows that aspects of linguistic structure that are not overtly marked in the input can be derived by efficiently combining multiple probabilistic cues. (Author/MSE)

Proposes an alternative account of the child's learning of nouns and adjectives that relies on properties of the semantic categories to be learned and of the word-learning task itself. In five experiments, a simple connectionist network was trained to label input objects in particular contexts; the network learned categories resembling nouns…

Investigates the availability of syntactic cues to verb meaning. In Experiments 1-3, adult subjects' judgments of verbs' semantic similarity were compared with other adults' judgments about the syntactic properties of the same verbs. In Experiment 4, subjects paraphrased sentences formed by pairing verbs with unaccustomed sentence frames. (54…

Children with specific language impairments (eight learning Italian, eight learning English as a first language) were studied for grammatical deficits. Italian-speakers used noun inflections, verb inflections, copula forms more than English-speaking counterparts, matched by utterance length. Articles were used similarly. Results were consistent…
