在两个实验中，我们调查了额叶损伤患者、年龄匹配的老年对照组和年轻受试者对最近学习的事实的记忆和对事实来源的记忆（即在何处和何时学习的事实）。在这两个实验中，额叶损伤的患者回忆起的事实与年龄匹配的受试者和年轻受试者一样多，但他们经常将事实归因于错误的来源。在第二个实验中，额叶损伤的患者和他们年龄匹配的受试者都比年轻的受试者犯了更多的源错误。这些发现表明，额叶可能在将事实与其学习的背景联系起来方面发挥着特殊作用。结果还讨论了在健忘症患者发生的源记忆障碍的光。
In two experiments, we investigated memory for recently learned facts and memory for the source of the facts (i.e. where and when the facts were learned) in patients with frontal lobe lesions, age-matched elderly control subjects, and younger subjects. In both experiments, patients with frontal lobe lesions recalled as many facts as their age-matched subjects and the younger subjects, but they frequently attributed facts to incorrect sources. In the second experiment, both patients with frontal lobe lesions and their age-matched subjects committed more source errors than younger subjects. These findings suggest that the frontal lobes may play a special role in associating facts to the context in which they were learned. The results are also discussed in the light of the source memory impairment that occurs in amnesic patients.
