  • Title: Differential effects of frontal-lobe lesions on cognitive estimation and spatial memory.
    Author: Smith ML, Milner B.
    Journal: Neuropsychologia; 1984; 22(6):697-705. PubMed ID: 6441896.
    Abstract:
    Patients with unilateral frontal- or temporal-lobe excisions and normal control subjects were tested on the recall of objects and of their location in an array. An incidental-learning situation was used, in which the task was presented as a test of the ability to estimate the prices of the objects. Patients with right frontal-lobe lesions were the only group impaired on price estimation, but a correlation was obtained between error-score in price estimation and lesion-size for the left frontal-lobe group. In contrast to patients with extensive right hippocampal excisions, both frontal-lobe groups were accurate on location-recall when tested immediately and again 24 hr later.
