Thirty-two subjects with unilateral cerebral tumors were assessed for the use of hypotheses and cognitive strategies during a visual discrimination task. Subjects with frontal lobe lesions attained fewer concepts and used fewer appropriate hypotheses than subjects with tumors confined to the posterior hemisphere, although there was no difference in total hypotheses used. Lose-stay errors were committed with greater frequency among patients with frontal lobe lesions, although not all subjects with frontal lobe tumors exhibited this error tendency. The results of hypothesis sampling and a second visual discrimination transfer task suggested that the frontal lobe deficit was related to difficulty in attending to multiple cues and in monitoring feedback to segregate relevant from irrelevant sources of information.
对32名单侧脑肿瘤患者在视觉辨别任务中使用假设和认知策略的情况进行了评估。与肿瘤局限于后半球的患者相比，额叶病变患者获得的概念更少，使用的适当假设也更少，尽管在使用的假设总数上没有差异。额叶病变患者出现失留错误的频率更高，尽管并非所有额叶肿瘤患者都表现出这种错误倾向。假设抽样结果和第二项视觉辨别转移任务表明，额叶缺陷与难以关注多个线索以及难以监测反馈以区分相关和不相关信息来源有关。
