Cerebral specialisation for receptive language in individuals with down syndrome

Two experiments examined cerebral specialisation for linguistic material in adults with Down syndrome (DS). For a dihaptic letter matching task, a left hand/right hemisphere advantage was observed for the DS group. For a visual field letter identification task, the DS data were suggestive of a left field/right hemisphere superiority. Thus, as predicted by our model (Elliott, Weeks, & Elliott, 1987), atypical cerebral organisation of speech …
