This article provides a conceptual review of the principles of input spacing as they might relate specifically to oral task repetition research and presents some of the common methodological considerations from the broader input spacing literature. The specific considerations discussed include the interaction between intersession intervals and retention intervals, the manipulation of posttests as a between-participants variable, the number of task repetitions, absolute versus relative spacing, the criterion of learning, task type versus exact task repetition, and blocked versus interleaved practice. Each of these considerations is discussed with links, as appropriate, to the relevant empirical input spacing and task repetition literature. The purpose of this review is to highlight how, in many cases, these methodological considerations have been overlooked by task repetition researchers, including in studies where input spacing has and has not been a direct focus, and to suggest ways of addressing these methodological shortcomings in future research.

任务重复研究中的间隔效应

本文提供了对输入间距原则的概念性回顾，因为它们可能与口头任务重复研究具体相关，并介绍了更广泛的输入间距文献中的一些常见方法论考虑因素。讨论的具体考虑因素包括会话间隔和保留间隔之间的相互作用、将后测作为参与者间变量的操作、任务重复次数、绝对间隔与相对间隔、学习标准、任务类型与精确任务重复以及阻塞与交错练习。这些考虑因素中的每一个都在适当的情况下通过相关经验输入间隔和任务重复文献的链接进行讨论。本综述的目的是强调在许多情况下，
