艾宾浩斯的研究真正揭示的是人类根据各自的遗忘规律安排复习效果拔群
其研究的局限性也是很明显的:
There are several limitations to his work on memory. The most important one was that Ebbinghaus was the only subject in his study. This limited the study's generalizability to the population. Although he attempted to regulate his daily routine to maintain more control over his results, his decision to avoid the use of participants sacrificed the external validity of the study despite sound internal validity. In addition, although he tried to account for his personal influences, there is an inherent bias when someone serves as researcher as well as participant. Also, Ebbinghaus's memory research halted research in other, more complex matters of memory such as semantic and procedural memory and mnemonics.
还是那句话,人和人的差异是非常大的,就算是同一个人,在背单词和记忆公式时的记忆曲线也是不同的
但很不幸的是,现在的工具基本上将y=1-0.56x^0.06这条线看做了铁律,并没有搞差异化,因而制定出来的前期计划往往不适用,或者有用但并非最佳
