Fig. 2From: The order of complexity of visuomotor learningHuman learning. a The thick, bright red line shows human subject 9’s unsigned error versus shot number, averaged over all 24 test blocks. The thinner, dark red line shows the shot-by-shot errors averaged across all 12 subjects; small vertical lines along this curve show standard errors of the mean, across subjects. b Red dots show the same subject’s errors on the 100-shot long block. The thick, bright red line is a running average of those errors, with a nine-shot sliding window. The thinner, dark red line is the mean running average across all subjects. We take each subject’s average error over shots 51–100 (pale gray interval) as a measure of their long-term accuracyBack to article page
