The aim of the present study was to determine if two levels of task similarity influenced acquisition, retention, and transfer performance of three simple motor skills. Sixty right-handed subjects were randomly assigned to one of five (n = 12) experimental conditions. Each subject performed 72 trials during acquisition. Twenty-four trials were recorded for each movement task. Following a 5-min unfilled retention interval, subjects performed 4 trials on each task before completing 12 transfer trials of a novel movement. Contextual interference effects for acquisition and retention were supported for low but not high similarity tasks. Further, the results suggest that a different memory representation exists for high and low similarity tasks.
本研究的目的是确定两种任务相似度水平是否会影响三种简单运动技能的习得、保持和迁移表现。60名右利手受试者被随机分配到五个（n = 12）实验条件之一。每个受试者在习得过程中进行72次试验。每个运动任务记录24次试验。在5分钟的无填充保持间隔后，受试者在每个任务上进行4次试验，然后完成一项新运动的12次迁移试验。对于低相似度但非高相似度任务，习得和保持的情境干扰效应得到了支持。此外，结果表明，高相似度和低相似度任务存在不同的记忆表征。
