Abstract: | The potential causes of decrements in children's understanding of big and tall (Maratsos, 1973, Maratsos, 1974, 10, 367–375) are reconsidered. On the basis of data from English-speaking children, two of these hypotheses, the Strong Cognitive Hypothesis and the Strong Semantic Hypothesis, offer equally plausible explanations for those decrements. However, data from Arabic-speaking children between 2;9 and 6;3, who do not show a similar decrement in their understanding of kabiir, support the Strong Semantic Hypothesis that decrements in English-speaking children's understanding of big and tall are due to their positing semantic features such as [+ Vertical] for one word and overgeneralizing them to related words. This, in turn, supports Carey's (M. Halle, J. Bresnan, & G. Miller (Eds.), Linguistic theory and psychological reality. Cambridge, Mass.: MIT Press, 1978. Pp. 264–293) theory that features are abstracted out for words after children are able to use those words correctly on the basis of stored haphazard examples. Further, the results support the view that children at least sometimes posit features for a word on the basis of its individual privileges of occurrence, rather than on the basis of what that word contrasts with. |
