Generalization across an increase in movement amplitude, with 4 interleaved trials. Data are plotted as in Fig. 2. A: movement kinematics show the same pattern as in Fig. 2A. Interleaved trials to the 30 cm target were made in the clockwise force field (orange). B: force production at the end of training was no different from expected. C: force production during the test for generalization was less than expected at velocities that exceeded velocities experienced during training (indicated by the dashed vertical lines). The difference was reliable (highlighted by the gray bar), but the extent of the difference was reduced compared with Fig. 2C. D: at the end of training on the 30 cm target, subjects produced the expected lateral forces. E: repeated-measures ANOVA revealed that actual force did not increase during the test for generalization.
