title: A developmental perspective of intermanual performance asymmetry in aiming.
abstract: This study compared intermanual performance asymmetry between adults and children of different ages in timing components of an aiming task. Participants manipulated a computer mouse with either hand, aiming to rapidly reach targets of different widths with a pointer on a monitor. Results showed longer deceleration movements with the left hand in children, leading to increased intermanual performance asymmetry when aiming at narrower targets. Increased intermanual performance asymmetry in children is conceptualized to derive from planning to minimize trajectory variability when controlling the nondominant hand.
