Figure 6.

Results: object-grasp and task-completion times distributions. Box & whiskers plots representing (A) object-grasp time (Tg) and (B) task-completion time (Tc) distributions for subjects in G2 on day 1,2,3 (d1, d2, d3) and for group G1. Black boxes refer to power grasps, white boxes to precision grasps and the gray ones to lateral grasps. Each box is delimited by the first and third quartile values; thick horizontal lines, instead, highlight median values. Whiskers show the extent of the rest of the data, while crosses represent the outliers.
