Are Two Hands (from Different People) Better than One? Transfer between Unimanual, Bimanual, and Intermanual Coordination Modes

摘要

We report an experiment investigating transfer effects between unimanual (one-handed), bimanual (twohanded),and intermanual (different peoples' hands) coordination modes. From an information-basedperspective, coordination at the individual level should positively transfer to coordination at theinterpersonal level, and vise versa. From a constraint-based perspective, simpler coordination tasks (e.g., atthe individual level) should positively transfer to a more complex one (e.g., at the interpersonal level), butnot vise versa. Participants drove a teleoperated rover using different manual coordination modes in awithin-subjects design, and their speed was measured. The resulting pattern of transfer effects acrosscoordination modes is better accounted for by a constraint-based explanation. However, those transfereffects disappear rapidly with practice. The current results lead us to conclude that team motor skills arenot immediately transferable to individual motor skills.
