Fig. 2. Construct validity of Bimanual Coordination in the LASTT model. The ability to grasp six pre-defined objects with the dominant hand and re-grasp and transport them with the non-dominant hand to pre-defined targets in the LASTT model was evaluated. Higher scores represent bad performance. The upper graph shows the scores of the participants in function to their exposure to laparoscopic surgery. The lower graph shows the median (interquartile range) scores of the three groups. Group 1 (G1, green): no or little exposure to laparoscopy. Group 2 (G2, yellow): intermediate exposure to laparoscopy. Group 3 (G3, yellow): important exposure to laparoscopy. ***P < 0.001 (G1 vs. G3); °°P < 0.01 (G2 vs. G3).
