Alterations in speech shadowing ability after cerebral injury in man.
Patients with penetrating wounds of the left cerebral hemisphere are inferior to normal control subjects and patients with right hemisphere lesions in their ability to shadow language stimuli presented at various rates. Their performance deteriorates rapidly at higher rates of stimulus presentation. Patients with bilateral cerebral penetration show similar patterns of deficits. The deficits on the shadowing task are especially prominent in patients who were dysphasic or dysarthric during the immediate postinjury period.
