| Research Abstract |
We focused on the effect of successive experiences during the simultaneous learning process. It had been reported that simultaneous learning of two opposing force fields with a random order was better than alternating order, even if both have the same total number of experiences. We assumed this was because the alternating schedule gave no chance to retry the same rotational transformation successively. To evaluate this assumption, we compared three training conditions : alternating every trial, alternating every two trials, and changed at random. Experimental results suggested that providing the chance of successive trials had a small positive effect on the simultaneous learning. However the subjects trained under the random condition still showed a significant advantage in comparison with those trained under the other conditions.
