Fig. 4.

Plots of mean transport distance and aperture for the control (no perturbation) and a selected set of size-perturbation conditions for a representative participant. (a) Transport distance, perturbation applied at 300 ms after movement onset. (b) Aperture, perturbation applied at 300 ms after movement onset. (c) Transport distance, perturbation applied at 100 ms, 200 ms, or 300 ms after movement onset. (d) Aperture, perturbation applied at 100 ms after movement onset, 200 ms after movement onset, or 300 ms after movement onset. Legend format: Object Size_Object Distance; arrows indicate perturbation of object size. Gray vertical dashed-dotted lines and solid circles indicate the timing of the perturbations.
