We investigated the ability of 25 patients with left unilateral spatial neglect to make a clock face by putting numbers inside a printed circle. Impairment seen in this clock-drawing test did not parallel neglect severity as judged by results of the line-cancellation and line-bisection tests, as well as the copying of a daisy. The score for clock drawing correlated highly with the verbal WAIS score. Most neglect patients with a verbal IQ of 87 or more could draw a clock face fairly well and used planning in placing the numbers 12, 3, 6, and 9 before the others. In clock drawing, verbal intelligence may compensate for left unilateral spatial neglect. We therefore recommend use of the line-cancellation and line-bisection tests, as well as the copying test, but do not recommend use of the clock-drawing test in the diagnosis of left unilateral spatial neglect.
我们研究了25名患有左侧单侧空间忽视的患者通过在打印好的圆圈内填写数字来绘制钟面的能力。通过线条消除、线条二等分测试以及雏菊临摹测试的结果判断，在这项钟面绘制测试中观察到的损伤与忽视严重程度并不平行。钟面绘制得分与韦氏成人智力量表（WAIS）的言语得分高度相关。大多数言语智商在87及以上的忽视患者能够较好地绘制钟面，并且在放置12、3、6和9这些数字之前会进行规划。在钟面绘制中，言语智力可能会弥补左侧单侧空间忽视。因此，我们建议使用线条消除和线条二等分测试以及临摹测试，但不建议在诊断左侧单侧空间忽视时使用钟面绘制测试。
