运动学习的文献表明，封闭的做法有利于更好地获得运动技能，而随机的做法有利于保留和转移。语言学习和记忆文献也提供了类似的证据。本研究的目的是探讨封闭与随机实践在治疗失名症的效果。该研究采用单中心随机交叉设计，对10名失名症患者进行两个重复实验阶段（两个封闭阶段和两个随机阶段）。每个阶段包括一个提示图片命名治疗。基于正确命名的探针比例，使用Tau-U计算个体治疗和维持效应以及加权平均值和组效应。10名参与者中有9名在四个阶段的每个阶段都表现出治疗效果。采集是可比的封闭和随机的做法。在7个封闭治疗阶段和12个随机治疗阶段后，观察到了维持效应。对于10名参与者中的4名，随机时间表导致训练物品的更好维护。虽然还需要进一步的研究，目前的数据表明，单词检索治疗与多次重复相同的项目，一个随机的介绍可能有利于维护治疗收益。
The motor learning literature has demonstrated that blocked practice facilitates better acquisition of motor skills, whereas random practice facilitates retention and transfer. The verbal learning and memory literature offers similar evidence. The purpose of this study was to investigate effects of blocked versus random practice in treatment for anomia. The study used a single site, randomized crossover design, with two replicated experimental phases (two blocked and two random) for each of 10 individuals with anomia. Each phase consisted of a cued picture-naming treatment. Individual treatment and maintenance effects, as well as weighted averages and group effects, were calculated using Tau-U based on the proportion of correctly named probes. Nine of 10 participants demonstrated treatment effects during each of the four phases. Acquisition was comparable for blocked and random practice. Maintenance effects were observed following seven blocked phases of treatment and 12 random phases of treatment across participants. For four of 10 participants the random schedule resulted in better maintenance of trained items. Although further research is needed, the present data suggest that for word retrieval treatment with multiple repetitions of the same items, a random presentation may benefit maintenance of treatment gains.
