报告的研究使用双任务的方法来评估与高和低上下文干扰（CI）的实践环境相关的注意力需求。讨论了两个具体问题。第一，在随机和封闭的训练时间表中，注意力需求是否存在差异？第二，在随机和封闭训练中出现的任何差异注意力需求的时间过程是什么？为了解决这些问题，在实践中探索了两个特定的时间位点：前响应间隔和试验间隔。假设反应前间隔包含重建活动，该重建活动是重建位置的中心。与此相反，试验间的间隔已被解释在以前的工作是关键的项目内和项目间的处理过程中进行随机练习的时间间隔。数据显示，一个典型的CI效应的主要按键任务。具体来说，块实践参与者显示上级的性能在培训过程中，但表现不如随机实践的个人在保留的时间。随机练习参与者的较差的采集性能与较高的认知需求在两个前响应和试验间的时间间隔比分配到封锁的做法的个人。更大的关注需求随机实践个人进行了讨论，可能会发生在两个预响应和试验间隔的过程。
The reported study used the dual-task methodology to assess the attention demands associated with high and low contextual interference (CI) practice environments. Two specific issues were addressed. First, is there a difference in the attention demands during random and blocked schedules of practice' Second, what is the time course of any differential attention demands that emerge during random and blocked training? In order to address these questions two specific temporal loci were probed during practice: a pre-response interval and the inter-trial interval. It was assumed that the pre-response interval contained the reconstructive activity that is central to the reconstruction position. In contrast, the inter-trial interval has been interpreted in previous work to be the interval in which critical intra- and inter-item processing is performed during random practice. The data revealed a typical CI effect for the primary key-pressing task. Specifically, blocked-practice participants displayed superior performance during training but performed less well than the random-practice individuals at the time of retention. The poorer acquisition performance of the random-practice participants was associated with higher cognitive demand during both the pre-response and the inter-trial intervals than that of individuals assigned to blocked practice. The greater attention demands for random-practice individuals are discussed with respect to processes that might occur in both the pre-response and the inter-trial intervals.
