Attentional costs of coordinating homologous and non-homologous limbs.

摘要: 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 ipsilateral limb combinations. Results indicated that: (a) focus further stabilised with cost at central level; (b) there was an inverse relationship between stability probe reaction time (RT) for all patterns, that is stronger coupling limbs lower cost. Overall, results support previous research suggesting attention plays important role in sustaining pattern co-variation can also be extended
