JUDGMENT OF LINE ORIENTATION IN PATIENTS WITH UNILATERAL CEREBROVASCULAR LESIONS

This study examined the relationship between visual neglect and abilit y to judge the angular orientation of lines in patients with unilatera l cerebrovascualar lesions. Participants were 75 patients with right-h emisphere cerebrovascular lesions (RCVA) and 39 patients with left-hem isphere cerebrovascular lesions (LCVA). All were administered the Judg ment of Line Orientation test (JLO). Results revealed that twice as ma ny RCVA patients (56%) exhibited impairment on the JLO as did LCVA pat ients (26%). In RCVA patients, much lower performance was seen in pati ents with left visual neglect. Among LCVA patients, no relationship wa s found between JLO performance and the presence of visual neglect. Co rrelations between JLO scores and WATS-R variables suggested that JLO performance may be related in part to general cognitive factors, as we ll as to other perceptual and spatial abilities.
