三个实验，利用14元素的手臂运动序列的设计，以确定是否恢复的视觉空间坐标，这需要在采集过程中使用的相同的空间位置的移动，结果在更好的效应器转移比恢复的电机坐标，这需要相同的模式的同源肌肉激活。结果表明，更好的转移时，视觉空间坐标恢复比运动坐标恢复时，无论实践量（1，4，或12天;实验1-3，分别）。转移（左到右，左打）是对称的视觉空间坐标恢复时，但不是当运动坐标恢复。当运动坐标恢复后12天的实践和视觉闭塞，转移是更好地从右肢向左，反之亦然。这些数据也与多个代码（视觉，空间和运动）在实践中发展的概念相一致，当各自的坐标恢复时，每个代码都有助于转移性能。此外，结果表明，当一个或多个坐标在转移测试中发生变化时，序列之间的链接（串联）会中断。
Three experiments utilizing a 14-element arm movement sequence were designed to determine if reinstating the visual-spatial coordinates, which require movements to the same spatial locations utilized during acquisition, results in better effector transfer than reinstating the motor coordinates, which require the same pattern of homologous muscle activation. Results demonstrated better transfer when visual-spatial coordinates were reinstated than when motor coordinates where reinstated regardless of the amount of practice (1, 4, or 12 days; Experiments 1-3, respectively). Transfer (left to right and fight to left) was symmetric when visual-spatial coordinates were reinstated but not when motor coordinates were reinstated. When motor coordinates were reinstated after 12 days of practice and vision occluded, transfer was better from fight limb to left than vice versa. The data are also consistent with the notion that multiple codes (visual, spatial, and motor) are developed over practice, with each contributing to transfer performance when the respective coordinates are reinstated. Further, the results indicate a disruption of the linkage (concatenation) between subsequences when one or more coordinates are changed on the transfer test.
