There are 31 participants, and the data collected in our lab (MAE104 – Clifton, Nottingham Trent University) from Oct 2018 to Dec 2018. We used our devices which are EEG, fNIRS for recording physiological data, and laparoscopic trainer box to perform basic laparoscopic tasks. The laparoscopic tasks are the Ring Transfer and Threading tasks. The Ring Transfer task involved grasping, lifting and relocating rings from one rod to another using both surgical instruments and was performed on a ring stack base (Inovus Medical, St Helens, UK). Four rods were selected and labelled A, B, C and D, at the left-hand bottom, top left-hand, top right-hand and bottom right-hand corners on the ring stack base respectively. Four rings were initially put over rod A at the beginning of the trial. The procedure includes picking up a ring from rod A and placing it onto rod B with the left-hand only. After transferring all four rings to rod B, participants used their left-hand only to grasp and lift up each ring, pass it to the right-hand and place it on rod C. The procedure was completed by moving the rings individually from rod C to D using the right-hand only. Threading task consisted of passing a piece of string through the holes in a pre-determined order. The holes were labelled 1-7 in a zigzag pattern on the Threading base. Participants could use both surgical tools, however, no restriction was made on the use of right, left or both hands. more...
