Analytic and global strategies in copying designs by unilaterally brain-damaged patients

Different strategies in copying designs were investigated in unilaterally brain-damaged patients. Site of lesions (right or left) and presence or absence of aphasia, seen as a planning disorder, were taken into consideration. Aphasic patients proved to be more inclined to use an analytic strategy rather than a global one, differing from both other brain-damaged patients and normals. A comparison between patients with right and left brain lesion failed to yield a significant difference.
