2.2.3. Grooved Pegboard Test

The Grooved Pegboard test [7] measured both motor speed and hand–eye coordination. It is a widely used metric that requires refined manual dexterity for completion. The pegboard apparatus is made up of a metal surface with a 5 by 5 matrix of keyhole-shaped holes in various orientations. The pegs have ridges on the sides that need to be twisted around or oriented differently in order to fit the pegs into the grooved holes. During the task, the child is told to insert all of the pegs into the 25 holes on the pegboard. They were also told to go as quickly as they can, use only their right or left hand, start from left to right, and pick up one peg at a time. The subjects completed two trials, first with their dominant hand and second with their non-dominant hand. Specific hand preference was evaluated by which ever hand the child used to draw during the mathematics story task. The score is calculated from the amount of time taken to complete all of the rows and also the number of pegs dropped.
