Subjects improve with extended practice on a constant-speed credit assignment rotation perturbation (csCARP) mapping. A: cursor trajectories of the first 5 trials to each target on a particular day for monkey N during experiment 1. Colored circles represent the target locations. Solid curves and shaded areas indicate the mean and SD of the trajectories to each target. Dotted circles represent the halfway point where angular errors are assessed. B: angular error and success rate across the multi-day training for experiments 1 (left) and 2 (right). Shaded areas around black lines represent SE. Each data point represents the average of 20 trials to each target, subsequently smoothed with a 5-step sliding window. Gray rectangle background indicates the perturbation session. C: average target acquisition time across days for experiments 1 (left) and 2 (right). Each data point represents the mean of the first 480 trials on each day; shaded area denotes SE.
