Dual-Finger Preferred-Speed Tapping: Effects of Coordination Mode and Anatomical Finger and Limb Pairings

摘要: Interlimb and interfinger coordination were examined in a dual-finger tapping paradigm which 16 subjects performed at preferred frequencies. Three bimanual finger combinations, random order (2 index; 2 middle; 1 index middle), in-phase antiphase modes, addition to unimanual combination (antiphase index-middle). Relative phase means within 3p accuracy for all conditions. A lower frequency was found vs. conditions, accompanied by phasing variability intrafinger consistency the antiphase. When changed from rate, modes became more alike and, same range, demonstrated no significant differences. The mixed-fingers tended have significantly values (a small fixed point drift) higher frequencies than symmetric task similar other Changes with different may be related differing perceptual informational constraints. Current models addressing natural of coupled oscillators do not account present data.
