作者研究了（a）意识到即将发生的滑动和（B）启动（加速学习）对获得性稳定性控制的肢体间转移的影响。在参与者中，24名年轻人中有12名没有被告知2次未训练的左侧滑倒（UNWARN），而另外12名知道24次右侧滑倒后第一次左侧滑倒（WARN）的确切时间和位置，所有参与者在行走时都知道。两组均将后向平衡丧失（BLOB）发生率从第一次滑动时的100%降至第24次滑动时的0%。作者发现，WARN中改进的稳定性控制的传递明显优于UNWARN，导致第一次左滑时BLOB的减少更大（分别为55%和92%）。预充很明显，第二次左侧滑动时没有BLOB，而第二次右侧滑动时有50%。因此，肢体间泛化可以通过认知来提高，并在启动中得到证实。
The authors examined the impact of (a) awareness of impending slip and (b) priming (to accelerate learning) on interlimb transfer of acquired stability control. Among the participants, 12 of 24 Young individuals were not informed of 2 impending slips oil the nontrained left-side (UNWARN), whereas the other 12 knew the exact timing and location of the 1st left slip (WARN) following 24 right-side slips, given to all participants while walking. Both groups reduced the backward loss of balance (BLOB) incidence from 100% oil the first slip to 0% on 24th slip. The authors found significantly better transfer of the improved stability control in WARN than in UNWARN, resulting in a greater reduction in BLOB on the 1st left slip (55% vs. 92%, respectively). The priming was evident with no BLOB on the 2nd left slip versus 50% on the 2nd right slip. Thus, the interlimb generalization can be improved by cognition and evidenced in priming.
