This study examined the relationship between visual neglect and ability to judge the angular orientation of lines in patients with unilateral cerebrovascualar lesions. Participants were 75 patients with right-hemisphere cerebrovascular lesions (RCVA) and 39 patients with left-hemisphere cerebrovascular lesions (LCVA). All were administered the Judgment of Line Orientation test (JLO). Results revealed that twice as many RCVA patients (56%) exhibited impairment on the JLO as did LCVA patients (26%). In RCVA patients, much lower performance was seen in patients with left visual neglect. Among LCVA patients, no relationship was found between JLO performance and the presence of visual neglect. Correlations between JLO scores and WAIS-R variables suggested that JLO performance may be related in part to general cognitive factors, as well as to other perceptual and spatial abilities.
本研究调查了单侧脑血管病变患者的视觉忽视与判断线条角度方向能力之间的关系。参与者包括75例右半球脑血管病变（RCVA）患者和39例左半球脑血管病变（LCVA）患者。所有患者均接受了线条方向判断测试（JLO）。结果显示，表现出JLO损伤的RCVA患者（56%）是LCVA患者（26%）的两倍。在RCVA患者中，左侧视觉忽视患者的表现要低得多。在LCVA患者中，未发现JLO表现与视觉忽视之间存在关联。JLO分数与韦氏成人智力量表修订版（WAIS-R）变量之间的相关性表明，JLO表现可能部分与一般认知因素以及其他感知和空间能力有关。
