cumulative pattern of practice effect

Explanation of a cumulative pattern of practice effect：Pashler (1991) "Assume further that this trace has a negatively accelerated decay function (i.e., it decays rapidly at first, then more and more slowly)... Over the course of repeated trials, the accumulation of multiple traces that have not quite decayed to zero would sum to yield the practice effect."

學習效應"累積形式"的中文解釋：在多次的再測過程，初期測量次數中，產生學習效應的數值會較大，且在每次的下一次測量中，又會產生一點學習效應，有持續增加(累積)的現象。漸漸地，學習效應曲線會趨近0斜率，達到穩定形式。
