The performances of three groups of patients were compared during two conditions of interference on a visual retention task. During the noninterference condition, the psychiatric, multiple-sclerosis, and brain-damaged patients functioned at a comparable level. The introduction of a distracting background reduced the level of functioning for only the brain-damaged group. This effect remained significant for the correct score when age and postmorbid intelligence functioning were controlled. These results were interpreted as reflecting the cortical nature of the deficits in resisting the distracting influence of the background interference procedure. Serial testing was recommended for the evaluation of the multiple-sclerosis group.
在视觉记忆任务的两种干扰条件下，对三组患者的表现进行了比较。在无干扰条件下，精神病患者、多发性硬化症患者和脑损伤患者的功能水平相当。引入一个干扰背景后，只有脑损伤组的功能水平下降。在控制了年龄和病后智力功能后，这种效应在正确得分方面仍然显著。这些结果被解释为反映了在抵抗背景干扰程序的干扰影响方面缺陷的皮质性质。建议对多发性硬化症组进行系列测试。
