Consequences of severe visual-spatial deficits for reading acquisition: evidence from Williams syndrome.

abstract：:For functional neuroimaging studies of stuttering, two challenges are (1) the elicitation of naturally stuttered versus fluent speech and (2) the separation of activation associated with abnormal motor execution from activation that reflects the cognitive substrates of stuttering. This paper reports on a proof-of-conc...
