Two experiments are reported in which the question of whether or not contextual interference effects are found in motor tasks that require the acquisition of new coordination patterns was examined. Participants (N = 18, Experiment 1; N = 12, Experiment 2) practiced 3 novel bimanual patterns (45 Degrees, 90 Degrees, and 135 Degrees relative phase) in either a random or a blocked order. No statistically significant acquisition or retention differences between groups were found when all 3 patterns were practiced on each of 2 days (Experiment 1). When the blocked group practiced 1 pattern on each of 3 acquisition days (Experiment 2), however, typical contextual interference effects were found: The blocked group performed better than the random group in practice, but the random group performed better than the blocked group in a delayed (by 1 week) retention test. The experiments revealed that contextual interference effects can arise in motor tasks that require the acquisition of new coordination patterns and are not limited to tasks involving novel scaling of a previously existing pattern.

机译：报告了两个实验，其中研究了在需要获取新的协调模式的运动任务中是否发现情境干扰效应的问题。参与者（N = 18，实验1； N = 12，实验2）以随机或封闭的顺序练习了3种新颖的双手模式（相对相位为45度，90度和135度）。在每2天的所有3种模式下均进行实验（实验1）后，各组之间的采集或保留差异均无统计学意义。但是，当受阻组在3个采集日中的每一天都练习1种模式时（实验2），发现了典型的情境干扰效果：受阻组在实践中的表现优于随机组，但在受阻组中，随机组的表现优于受阻组延迟（1周）保留测试。实验表明，在需要获取新的协调模式的运动任务中，可能会产生上下文干扰效应，而这种局限性并不局限于涉及对现有模式进行新颖缩放的任务。
