Fig. 6: Group comparisons of actual hold times.

Interquartile ranges display an upward trend in achieved holding times for the conditions. The early completion of the No-Goal condition reflects a premature discontinuation of task when individuals are given no end time. The higher upper interquartile in the 240 s condition, that extends towards the higher whisker, also indicates how milestones (a termination point) aid potentials in completing tasks that would otherwise go undiscovered.
