Classification and recall of pictures of familiar objects were studied in 21 normal control subjects and 75 patients with unilateral cerebral excisions. The patients with frontal-lobe excisions were impaired at categorizing the pictures and at recalling the objects depicted. Left and right temporal-lobe groups performed the sorting task normally, but the left temporal-lobe groups were impaired at recalling picture names. The right temporal-lobe groups were unimpaired. A negative correlation between the number of items uncategorized and the number recalled was found in the right frontal-lobe group but not in the left, who were impaired also at recalling the items that they had classified correctly. It is concluded that impaired categorization played a major role in determining the recall deficits in the right frontal-lobe group but not in the left, whose impaired recall may also be due to defective retrieval. The poor recall of the left temporal-lobe groups is thought instead to depend on abnormally rapid forgetting.
对21名正常对照受试者和75名单侧脑切除患者进行了熟悉物体图片的分类和回忆研究。额叶切除患者在图片分类和回忆所描绘物体方面存在障碍。左、右颞叶组在分类任务上表现正常，但左颞叶组在回忆图片名称方面存在障碍。右颞叶组未受影响。在右额叶组中发现未分类项目数量与回忆项目数量之间存在负相关，而左额叶组未发现这种相关性，左额叶组在回忆他们正确分类的项目时也存在障碍。得出的结论是，分类障碍在确定右额叶组的回忆缺陷中起主要作用，而左额叶组并非如此，左额叶组的回忆障碍也可能是由于检索缺陷所致。相反，左颞叶组的回忆不佳被认为取决于异常快速的遗忘。
