Interleaving examples of to-be-learned categories, rather than blocking examples by category, can enhance learning. We examine the reliability of the interleaving effect between- (Experiments 1 and 2) and within-participants (Experiment 3). As a between-participant effect, we examined a broad spectrum of working memory by both measuring individual capacity and manipulating the task demand. Findings reveal a robust interleaving effect across the spectrum, eliminated only at the lowest and highest ends, but never reversed. In Experiment 3, we used an empirically defined source of potential heterogeneity by examining whether the size of the interleaving benefit a participant experiences on one set of stimuli predicts the size of the interleaving benefit that same participant experiences on two other sets of stimuli. It did not, with only a very small correlation between the two more similar stimuli sets. Taken together, these results add to the burgeoning literature on the robustness of the interleaving benefit.

将要学习的类别的示例交错，而不是按类别阻塞示例，可以增强学习。我们检查了 -（实验 1 和 2）和参与者内部（实验 3）之间交错效应的可靠性。作为参与者之间的效应，我们通过测量个人能力和操纵任务需求来检查广泛的工作记忆。调查结果揭示了整个频谱的强大交错效应，仅在最低端和最高端被消除，但从未逆转。在实验 3 中，我们通过检查参与者在一组刺激上体验的交错收益的大小是否预测同一参与者在其他两组刺激上体验的交错收益大小，使用了一个经验定义的潜在异质性来源。它没，两个更相似的刺激集之间只有非常小的相关性。综上所述，这些结果增加了有关交错收益稳健性的新兴文献。
