Shared dynamics of attentional cost and pattern stability
Résumé
Examined the informational activity devoted by the CNS to couple oscillating limbs in order to sustain and stabilize bimanual coordination patterns. 10 university students (aged 20–25 yrs) performed an RT task and inphase and anti-phase coordination patterns at several frequencies, under conditions of shared attention or primary attention given to the coordination task. Results show a U-shaped evolution of pattern stability and attentional cost, as a function of oscillation frequency. Findings suggest that central cost and pattern stability covary and may share common, high order dynamics. Stabilizing a coordination pattern incurs a central cost that depends on its intrinsic stability. (PsycInfo Database Record (c) 2020 APA, all rights reserved)
