过去t（j）有时会收到各种实践的记忆痕迹的强度？强度积累方程提出了以下内容：强度= Sigma t（j）（-d），其中求和与迹线的实践相比。该方程式可以预测实践的权力法和保留权的权力法。本文报告了该方程式的预测与5个实验的拟合。在这些实验中，参与者接受了多达240次在间隔400天内分发的实践试验。这些实验还改变了参与者是仅仅在练习检索项目还是应用相对复杂的规则。当假定心理时间的通过后，基于此方程的模型成功地符合所有数据。将强度积累方程与保留函数的其他概念以及保留函数与实践函数的关系进行了比较。
What is the strength of a memory trace that has received various practices at times t(j) in the past? The strength accumulation equation proposes the following: strength = Sigma t(j)(-d) where the summation is over the practices of the trace. This equation predicts both the power law of practice and the power law of retention. This article reports the fits of the predictions of this equation to 5 experiments. Across these experiments, participants received as many as 240 trials of practice distributed over intervals as long as 400 days. The experiments also varied whether participants were just practicing retrieving an item or practicing applying a relatively complex rule. A model based on this equation successfully fit all the data when it was assumed that the passage of psychological time slowed after the experimental session. The strength accumulation equation was compared with other conceptions of the retention function and the relationship of the retention function to the practice function.
