UNLABELLED
BACKGROUND/STUDY CONTEXT: The purpose was to determine if aging interacts with the coding of a simple spatial-temporal movement sequence.
METHODS
An interlimb practice paradigm (24 participants; 12 young adults [age: 23-29]; 12 old adults [age: 65-78]) was designed to determine the coordinate system (visual-spatial/motor) that is used to code the movement sequence. Practice was scheduled over 2 days involving either the same visual-spatial or the same motor coordinates. On Day 3, two retention tests (Day 1/Day 2) were conducted.
RESULTS
Keeping the motor coordinates the same during acquisition resulted in superior retention only for younger adults.
CONCLUSION
The data provide strong evidence that the motor code plays a dominant role in acquiring simple movement sequences for younger adults, but not for older adults.

背景/研究背景：目的是确定衰老是否与简单时空运动序列的编码相互作用。
方法
设计了一种肢体间练习范式（24名参与者；12名年轻人[年龄：23 - 29岁]；12名老年人[年龄：65 - 78岁]）来确定用于编码运动序列的坐标系（视觉空间/运动）。练习安排在2天内进行，涉及相同的视觉空间或相同的运动坐标。在第3天，进行了两次保持测试（第1天/第2天）。
结果
在习得过程中保持运动坐标相同仅对年轻人有更好的保持效果。
结论
数据提供了有力证据，表明运动编码在年轻人获取简单运动序列时起主导作用，但在老年人中并非如此。
