Anomalous cerebral lateralization and Down syndrome.
Contrary to Bryden, McManus, and Bulman-Fleming's claim, the dichotic listening and handedness literature indicate that persons with Down syndrome exhibit a unique pattern of cerebral specialization. This pattern creates difficulty for any model of laterality that proposes random specialization of function in the absence of a predisposition toward left hemisphere lateralization for language and motor control.
