  1. First, separate classifiers were trained on each of the named movement conditions. Then, classification performances were estimated on ‘attempted movement’. Results are given as classification accuracy (95% CI): for each individual classification accuracy the binomial 95% CI is given, for the mean classification accuracy the standard 95% CI is given.
