The average radial deviation for three groups exhibited reductions in the first session over the course of trials (8 trial moving average shown), as well as disruptions following exposure to periods free exploration training (blue dashed). Groups (by rows) differed in the sequence of training fields for each session (columns): null-field, combined-load, negative-viscosity (NCV), null-field, negative-viscosity, combined-load (NVC), null-field for each session (NNN). Note that all evaluation trials are in null-field conditions.
