We present a neural network model of referent identification in a visual world task. Inputs are visual representations of item pairs unfolding with sequences of phonemes identifying the target item. The model is trained to output the semantic representation of the target and to suppress the distractor. The training set uses a 200-word lexicon…

Data from four recent language studies are examined to explore issues in concept-word relationships. Issues considered include: lexical development, bases of application, single-word functions, semantic domains, categorizing through naming, and concept matching as a model of word learning. (JMB)

Argues that inferring the intension (meaning) of children's words solely from the words' extension (referential scope) is problematic and describes two studies of the intension of children's words which involve a different approach. (JMB)

Assesses whether 30 children aged three-five years had a preferred direction in responding to "when"-questions and whether this preference could be influenced by story structure. Results indicated that children showed a preference for "after"-type responses and that productions of "before" were more likely to be…

Children exhibiting a referential orientation seem more likely to acquire new object names than nonreferentially oriented children. Also, children's selection of words may be influenced by the phonological structure of the words. (Author/RH)

Examines the understanding of the pragmatic function of mental terms ("think,""know,""guess") to express the relative certainty of 69 children aged 3-11. Results showed an improvement with age for the "know-think" and "know-guess" contrasts, but no improvement with age for the…

Results of four experiments suggest that two-year-olds may be capable of forming inclusion relations when they hear a novel word for an object that already has a familiar name. (PCB)

Examines preschool children's comprehension of the differing implications of the verbs "think" and "know". Results indicated that 4-year-olds, but not 3-year-olds, understood the differences between the terms. (JMB)

Selected spontaneous errors of word choice made between the ages of two and five by two children whose language development had been followed longitudinally were analyzed for clues to semantic developmnet. (JMB)

Younger and older children were asked to label pictures of nonprototypic, container-like objects in an effort to test Nelson's theory regarding the primacy of the functional core in young children's meaning structures. Contrary to expectations, the older, intermediate age children were influenced more by functional context than were the younger,…
