Adult behaviors, such as vocal production, often exhibit temporal regularity. In contrast, their immature forms are more irregular. We ask whether the coupling of motor behaviors with arousal changes gives rise to regularity: Do they drive transition from variable regular output over course development? used marmoset monkey production explore this putative influence on nonlinear in developing patterns. Based a detailed analysis and dynamics marmosets, we put forth general model incorporating auditory feedback loops for spontaneous production. Using model, show that stable oscillation can emerge baseline increases, predicting stochastic periodic oscillations observed during development. further provide solution how explain development joint consequence energetic growth social feedback. Together, plausible mechanism arousal-mediated adaptive behavior.
