本综述研究了集中练习和间隔练习条件与任务绩效之间的关系。一项对63项研究（112个效应量）的荟萃分析得出的总体平均加权效应量为0.46，表明间隔练习条件下的个体表现显著高于大规模练习条件下的个体。然而，随后的分析表明，正在练习的任务的性质，试验间隔时间，以及这两个变量之间的相互作用显着缓和实践条件和性能之间的关系。此外，与那些严格性较高的研究相比，在方法学严格性较低的研究中发现了显著较高的效应量。未来的研究方向和应用的研究结果进行了讨论。
The present review examined the relationship between conditions of massed practice and spaced practice with respect to task performance. A meta-analysis of 63 studies with 112 effect sizes yielded an overall mean weighted effect size of 0.46, indicating that individuals in spaced practice conditions performed significantly higher than those in massed practice conditions. Subsequent analyses, however, suggested that the nature of the task being practiced, the intertrial time interval, and the interaction between these two variables significantly moderated the relationship between practice conditions and performance. In addition, significantly higher effect sizes were found in studies with low methodological rigor as compared with those studies higher in rigor. Directions for future research and applications of the findings are discussed.
