Deficient programming in spatial learning after frontal lobe damage.
Patients with anterior or posterior brain damage and control subjects performed a spatial sequence learning task in which the score obtained depended on the subject's ability to set sub-goals appropriate for his learning capacity. The anterior group obtained lower scores and more frequently set inadequate sub-goals than the posterior group. No anterior vs posterior difference was found on a similar learning task in which another sequence was learnt by predetermined sub-goals. The result supported the hypothesis that frontal lobe lesions disturb programming or goal-based search for action structure on spatial learning.
