The Readiness-Efficiency Coupling: Synergy of High Preparatory and Reduced Execution Fractal Complexity in Motor Learning

↓), reflecting automated efficiency. Crucially, a three-way interaction revealed that the fastest response times were achieved specifically when high preparatory readiness was coupled with reduced execution complexity. This coupling collapsed upon transfer to novel sequences, indicating task-specificity. State-space analysis confirmed the Readiness-Efficiency configuration acts as a functional attractor, with the probability of occupying this state increasing five-fold through practice. These findings demonstrate that expertise is characterized by dynamic flexibility - the capacity to dissociate and pair control regimes to meet phase-specific demands - providing a mechanistic framework for profiling skill acquisition.
