Figure 2.

(A) shows the experimental setup (without speakers) with the monitor showing an underhand trial for the right hand. The visual occlusion goggles in their closed state are located to the left of the two-button response pad. The experimenter monitor with keyboard and mouse, used to input participant data, on-line grip error coding, and general experiment control can be seen on the left of the image. (B) shows a participant executing an underhand grasp with the left hand, while using the inactive right hand to keep the right response button pressed as instructed. (C) shows dimensions of the equipment used and distances between the equipment. Arrows leaving the picture plane extend to the forward edge of the table (80 mm from the forward edge of the response pad). Distance vectors parallel to the table plane are parallel and perpendicular to respective table edges. Vertical distance vectors are orthogonal to the table plane.
