    abstract="Late talkers (LTs) --- children who show a marked delay in
    vocabulary learning --- have also been shown to differ from
    normally-developing (ND) children with respect to the semantic organization
    of their learned vocabulary.  We use a computational model of word learning
    to study how individual differences between LTs and NDs give rise to
    differences in abstract knowledge of categories emerging from learned
    words, and how this affects their subsequent word learning.  Our results
    suggest that the vocabulary composition of LTs and NDs differ at least
    partially due to a deficit in the attentional abilities of LTs, which also
    results in the learning of weaker abstract knowledge of semantic categories
    of words.",
