Capturing Developmental Change in Regulation Processes Using Dynamic Systems Models: Borrowing Differential Equations from Ecology

Developmental theories emphasize nonlinear dynamic processes occurring over multiple time-scales. Following this, we map theoretical propositions of self-/co-regulation when infants are distressed to fishery model parameters where fish's reproduction and farmers' harvesting contribute to population size. We examine self-/co-regulation changes with age as mother-infant dyads gain efficiency in achieving calm.
