Median estimation per level for Exp II. Estimated value, i.e. estimated closing velocity/vibration, plotted against correct stimulus, i.e. generated velocity/vibration, with every boxplot representing the median (circle), interquartile range (box), range (line), and outliers (pluses) of all subjects’ medians for one level. Each subpanel represents one of the feedback conditions (see title). The black line is the reference line, which would reflect perfect responses. Significant differences (p < 0.05) from that line are indicated by asterisks
