109 patients, affected by right (40), left (44) and widespread (25) cerebral lesions and 20 patients without signs of cerebral involvement, taken as a control group, were given two sets of copying drawings. For the first task the patients were asked to copy directly a drawing; to perform the second test they were given guiding landmarks (programmation elements). The aim of this study was to check the hypothesis advanced by Hecaen and Assal (1970), that the presence of landmarks can improve the performance of left brain damaged patients while leaving unchanged the right brain damaged patients' scores. The performances of the direct copy and of the copy with landmarks showed a high correlation level both in left and in right hemispheric patients; thus the authors' results failed to confirm the hypothesis. Some implications of these findings are discussed.
