Dissociating effects of error size, training duration, and amount of adaptation on the ability to retain motor memories
After controlling for both training duration and the amount of learning, we found essentially identical retention when comparing gradual and abrupt training for two different types of force-field dynamics. By contrast, we found that retention was markedly higher for long-duration compared to short-duration training for both types of dynamics. These results demonstrate that the duration of training has a far greater effect on the retention of motor memory than the exposure rate during training. We show that a multi-rate learning model provides a computational mechanism for these findings.”
