Fig. 3.
Structural learning of visuomotor rotations. (A) Learning curves for a block of +60° rotation trials performed by a group that had experienced random rotations before (R-learner, red), a control group that had only experienced movements with veridical feedback (blue) and a group that experienced random linear transforms and ±60° rotations (green). The rotation group shows strong facilitation. (B) Learning curves for a subsequent block of −60° rotation trials performed by the same groups. The interference effect that can be seen in the control group is strongly reduced in the rotation group. (C) Learning curves for a subsequent block of +60° rotation trials performed by the same groups. Again the random rotation group shows a performance advantage in the first 10 trials. The median error over all subjects is shown and the pertinent interquartile confidence interval.
