Speed-accuracy tradeoff for able-bodied individuals and amputees. Trial completion time is plotted against the number of errors per trial for able-bodied individuals (left) and below-knee amputees (right). A “speed accuracy tradeoff” is defined as an inverse relationship between completion time and error rate. The bracket indicates that there was a statistically significant relationship between the number of errors per trial and completion time for below-knee amputees (linear regression, p < 0.001), but not able-bodied individuals.
