| Abstract | [Introduction]
The questions addressed in this paper concern the effect of greatly impoverished general intellectual endowment on the acquisition of language structure over time, focusing upon children with Down Syndrome (DS). In asking this question, it is necessary to resolve two very well-documented findings regarding the language structures associated with DS. On the one hand, children with DS often have great difficulty acquiring language, generally showing delays relative to traditional motor, intellectual or social indices (Gibson, 1978). Indeed, it appears that children with DS may have even more difficulty in acquiring language structures than other subgroups of retarded children; this difficulty is most pronounced in the syntactic-grammatical domain (e.g. Burr and Rohr, 1978; see Fowler, in press for a review). |
