Average aiming axes and angles of all groups in experiment 2 and comparisons of the aiming angles between and within groups.

The average aiming axes and angles are consistent with a representation of the partially learned perturbation in extrinsic coordinates and with a narrow generalization to different targets. The colors are as in Fig 8. (a) The course of the aiming axes (dots) averaged over participants in each group, and the ideal axis (arrows) in each session. (b) The time course of the aiming angles (dots) averaged over participants and the standard error (dark shading) of the aiming angles in each group. The light curves show the time courses of the aiming angles of each participant. The dashed lines separate between the different sets of trials. (c) Within groups comparisons of the three-trials averaged aiming angles of all participants (dots) in each of the key stages. The bars and error bars are the mean ± standard error. *p < 0.05, **p < 0.001. The effect sizes are in the inset. (d) Between groups comparisons of the three-trials averaged aiming angles of all participants in the early TRN stage, the late TRN stage, and the early TFR stage).
