This study aimed to examine the attentional demands of coordinating movement patterns across limbs. Eighteen participants performed a circle drawing task involving in-phase and anti-phase coordination modes under homologous, contralateral and ipsilateral limb combinations. Results indicated that: (a) attentional focus further stabilised coordination patterns with a cost at the central level; (b) there was an inverse relationship between stability and probe reaction time (RT) for all coordination patterns, that is the stronger the coupling between the limbs the lower the central cost. Overall, the results support previous research suggesting that attention plays an important role in sustaining coordination pattern stability and that the co-variation between coordination stability and central cost can also be extended to coordination across limbs. © 2004 Elsevier B.V.
