| summary | In this talk, I will present some works illustrating the relevance and the limits of the application of dynamical systems theory for investigating human motion. I will first discuss the notions of stability, robustness and resilience in this framework.I will show the limits of bifurcation analysis for a system submitted to a varying stimulus: in this case considering the relative time scales of the stimulus and the dynamics becomes essential. I will then present a few tools for analyzing behavioral sequences based on dynamical systems concepts: recurrence plots, Kolmogorov entropy and mutual information, variable-length Markov chain. I will argue that a prior encoding of the time series into discrete sequences allows incorporating preliminary knowledge and filtering out individual variability. |
