This study was designed to examine Ribot's hypothesis that the probability of forgetting an event is inversely related to the time since the occurrence of that event. Patients with senile dementia (N = 20; mean age = 67.3) and normal controls (N = 24; mean age = 69.4) were given two tests of memory for persons and events that became famous between 1930 and 1975. The results indicate that patients with senile dementia do have significant (p less than .001) difficulty recalling information from remote memory. The results do not support Ribot's hypothesis, however. The dementia patients show a relatively consistent recall deficit over the time period examined. There appears to be a trend for poorer recall of material from the 1960s and 1970s, possibly reflecting anterograde learning deficits early in the course of senile dementia.
本研究旨在检验里博的假设，即遗忘某一事件的概率与该事件发生后的时间呈反比。对患有老年痴呆症的患者（N = 20；平均年龄 = 67.3岁）和正常对照组（N = 24；平均年龄 = 69.4岁）进行了两项测试，测试内容为对1930年至1975年间成名的人物和事件的记忆。结果表明，老年痴呆症患者在回忆远期记忆信息方面确实存在显著困难（p <.001）。然而，结果并不支持里博的假设。痴呆症患者在所研究的时间段内表现出相对一致的回忆缺陷。对于20世纪60年代和70年代的材料，似乎存在回忆较差的趋势，这可能反映了老年痴呆症病程早期的顺行性学习缺陷。
