The bimanual finger-oscillation symmetry tendency is perceptual rather than neuromuscular: the symmetrical pattern stays stable across congruous and incongruous hand positions while the parallel pattern disintegrates with speed¶

Subclaims¶

q2 i? In Mechsner et al.'s (2001) four-hand-position variant of Kelso's paradigm, the symmetrical oscillation pattern remained stable at high frequencies regardless of hand position, while the parallel pattern switched to symmetry, supporting a psychological over a physiological interpretation. → Dor Abrahamson · Franz Mechsner 2022

q2 · i? · theoretical · r3

Experimental variant replication of Kelso's bimanual finger-oscillation paradigm by Mechsner et al. (2001), testing all four palm-down/palm-up hand-position combinations. The article reports that the result was "completely independent of congruous or incongruous hand positions", dissociating perceptual from neuromuscular accounts. No effect size or sample size is printed.

"Instead, completely independent of congruous or incongruous hand positions, the symmetrical oscillation pattern was always stable up to the highest oscillation frequencies, while the parallel pattern disintegrated with increasing metronome speed and switched into a symmetrical pattern."

• An otherwise impossible 4:3 bimanual circling frequency relationship can be performed comfortably when it serves visual symmetry of visible proxy flags — related
• Difficulty maintaining a 90° phase-shifted bimanual circling pattern reflects an unsuitable strategy rather than neuromuscular constraint, and spatial or imagined marks render the task easy — related
