The detection of errors in sentences after right hemisphere brain damage.
Several experiments have shown that non-aphasic, right hemisphere-damaged adults encounter difficulty solving syllogistic reasoning problems. In order to confirm and further explore the nature of this deficit with different linguistic material, patients with focal cerebral insult were asked to detect logical errors in sentences describing familiar causal situations. The findings revealed significant impairments in detecting errors after insult to anterior portions of the right hemisphere and to the left hemisphere, but qualitatively different patterns of errors in these two groups of patients. We conclude that the right hemisphere may make a unique contribution to sentence processing.
