The current study examined the performance of each limb as it reached across the body (the hard task), while yoked to it’s ipsilateral reaching counterpart (the easy task).

Most of the population is dextral, showing a clear preference for performing the vast majority of tasks with their right hand. Peters (1981) suggested that an asymmetrical bias in attention (toward the right hand in right handers) could account for many manual asymmetries in bimanual task performance, with the left hand unable to perform the attentionally demanding portion of the task. Likewise, Honda (1982) demonstrated preferential monitoring of the dominant hand during a bimanual reaching task. Recent evidence has also shown an intentional (i.e. output related motor attention) bias toward the dominant hand (Bestelmeyer & Carey, 2004), another possible factor …
