行为研究中提出的解释性假设假设，重复性较低的练习计划（例如随机练习）似乎比重复性较高的练习组织类型（例如恒定练习）需要更大的认知努力。所有这些假设都强调，较少重复的练习计划会促进对记忆过程的需求增加。在本研究中，我们采用电生理学方法研究了随机和持续练习计划中涉及的认知努力。二十一名男性参与者练习了顺序按键任务，其目标有两个：学习相对计时维度和学习绝对计时维度。六十次试验按照固定的练习计划进行（只有一个绝对计时目标），六十次试验以随机顺序进行（三个绝对计时目标）。使用两种基于脑电图的认知状态测量：（a）任务投入（感觉处理和注意力资源）和（b）心理负荷（工作记忆负荷）。结果表明，在分析任务投入度时，随机练习比持续练习引起更大的认知努力。在整个练习过程中，持续练习条件下的任务投入和脑力负荷比随机练习条件下减少得更多。在随机实践中观察到的对感觉处理的需求不断增加，为实践组织开辟了一个新的令人兴奋的研究领域。
Explanatory hypotheses proposed in behavioral studies assumed that less repetitive practice schedules, such as random practice, seem to demand greater cognitive effort than more repetitive types of practice organization, such as constant. All of these hypotheses emphasize the enhanced demand to memory processes promoted by less repetitive practice schedules. In the present study, we investigated the cognitive effort involved in random and constant practice schedules with an electrophysiological approach. Twenty-one male participants practiced a sequential key-pressing task with two goals: learning the relative timing dimension and learning the absolute timing dimension. Sixty trials were performed in a constant practice schedule (only one absolute timing goal), and sixty trials were performed in random order (three absolute timing goals). Two electroencephalography based measures of cognitive states were used: (a) task engagement (sensory processing and attention resources) and (b) mental workload (working memory load). The results showed that random practice induced greater cognitive effort than constant practice when task engagement was analyzed. Throughout practice, both task engagement and mental workload decreased more in the constant practice condition than in the random practice condition. The increased demand for sensory processing observed in random practice opens a new exciting field of study in practice organization.
