Standardized pegboard of the MLS system. For the subtests steadiness and contour copying the pegboard is presented in an upright position, for the subtests aiming and tapping in a horizontal position. For the subtest steadiness the participants inserted a stick in a hole (5.8 mm diameter, 32 seconds duration, top row, second one from centre) and were required to keep it there without touching by accident the lateral wall or back wall of the hole. The subtest contour copying requires the copying of a given trace without touching the lateral or back walls of the milled out trace (please see Figure 1 third row from top). The subtest aiming requires the volunteer to tap as fast and exact as possible along a line of 20 small circles (diameter 5 mm, distance between circles 4 mm) without touching the pegboard itself (fourth row of the pegboard in Figure 1). The subtest tapping consists of the instruction to tap on a rectangular plate (40mm one side) as fast and often as possible (quadratic area in the sixth row of the pegboard in Figure 1).
