A new computerized test for visual neglect and extinction was developed and evaluated by testing twenty-five patients with right-hemisphere cerebrovascular accidents. The test consisted of a series of unilateral or bilateral lights on a semicircular array to which the subject responded by pushing a button. A computer controlled the sequence of stimuli and stored the responses. Results of the computer test were compared to conventional occupational therapy and beside clinical tests. Extinction was present in 16 subjects on the computerized test, and in 11 on the clinical test. Neglect was present in 13 subjects on the computerized test, in seven subjects on the occupational therapy test, and in five subjects on the clinical test. The computerized test was more sensitive than the other tests. On both computerized and clinical testing, all subjects with left-sided neglect also had left-sided extinction, but not all subjects with extinction had neglect. Neglect may represent a more severe manifestation of an underlying perceptual defect that produces both neglect and extinction.
通过对25名右侧脑血管意外患者进行测试，开发并评估了一种用于检测视觉忽视和消退的新型计算机化测试。该测试由半圆形阵列上的一系列单侧或双侧灯光组成，受试者通过按按钮做出反应。计算机控制刺激序列并存储反应。将计算机测试结果与传统职业疗法及床边临床测试结果进行比较。在计算机化测试中，16名受试者存在消退现象，在临床测试中，11名受试者存在消退现象。在计算机化测试中，13名受试者存在忽视现象，在职业疗法测试中，7名受试者存在忽视现象，在临床测试中，5名受试者存在忽视现象。计算机化测试比其他测试更敏感。在计算机化测试和临床测试中，所有左侧忽视的受试者也存在左侧消退现象，但并非所有有消退现象的受试者都有忽视。忽视可能代表了一种潜在感知缺陷的更严重表现，这种缺陷会导致忽视和消退。
