According to S. T. Klapp (1995, 1996), extensive practice serves to induce the concatenation of multiple-element responses. One benefit of the chunking process, argued Klapp, is more efficient execution of motor programming. The authors conducted the present study with 30 participants to investigate that proposition. The chunking process was found to be very transient following some practice regimes. Specifically, compared with exposure to random practice, extensive blocked practice resulted in only temporary movement sequence consolidation. The present results provide support for the claim that random practice not only leads to improvements in the completion of intratrial movement planning processes but also affects the structure of the memory developed during practice. Both components are important contributors to long-term improvements in movement preparation associated with a high contextual-interference practice condition.
根据S. T. 克拉普（1995年、1996年）的观点，大量练习有助于引发多元素反应的串联。克拉普认为，组块过程的一个好处是运动编程的执行效率更高。作者对30名参与者进行了本研究，以调查这一观点。结果发现，在某些练习方式之后，组块过程非常短暂。具体而言，与随机练习相比，大量的集中练习只会导致运动序列的暂时巩固。目前的结果支持了这样一种说法，即随机练习不仅能提高试验内运动计划过程的完成度，还会影响练习过程中形成的记忆结构。这两个因素都是与高情境干扰练习条件相关的运动准备长期改善的重要因素。
