A study of the spacing effect was conducted within a short-term motor memory framework. In Experiment 1 subjects received one or six repetitions of a discrete linear movement at intervals of 5 or 60 sec, and with a constant retention interval of 30 sec. The performance over 10 trials was analyzed in terms of algebraic, absolute, and variable error. The facilitation associated with longer intervals found in verbal retention situations was obtained in the present study for algebraic error only. The results were discussed in terms of the several hypotheses offered by Hintzman (1974), and a mechanism for the operation of differential attention was suggested. Inconsistencies with previous data were discussed. Experiments 2 and 3 addressed some unresolved issues from Experiment 1 and additional support for the differential-attention hypothesis was obtained.
在短期运动记忆框架内进行了一项关于间隔效应的研究。在实验1中，受试者以5秒或60秒的间隔接受离散线性运动的一次或六次重复，且保持间隔恒定为30秒。通过代数误差、绝对误差和可变误差对10次试验中的表现进行了分析。本研究仅在代数误差方面获得了在言语记忆情境中发现的与较长间隔相关的促进作用。根据欣茨曼（1974年）提出的几种假设对结果进行了讨论，并提出了一种差异注意力运作的机制。讨论了与先前数据的不一致之处。实验2和实验3解决了实验1中一些未解决的问题，并获得了对差异注意力假设的额外支持。
