Bilateral symmetry in coincident timing: a preliminary investigation.
The purpose of this study was to investigate the coincident timing accuracy of the preferred and nonpreferred limbs in a ballistic striking task. A secondary purpose was to examine subjects' perception of their performance proficiency with each limb. 30 right-hand preferred subjects performed a 60-cm horizontal arm motion to displace a wooden barrier in coincidence with the final light in a series that traveled down a runway. Interestingly, while both the preferred and nonpreferred limbs were equally proficient in temporal accuracy, 80% of subjects perceived a bilateral asymmetry in performance. The influence of this perception on bilateral skill performance and acquisition remains in question.
