Schore (2012) describes how the ‘rhythmic developmental movement’ between survival-security and exploration ‘etches’ a template in the brain ‘for the rest of the lifespan’ (p.387). The rhythmic movement outward for exploration and inward for safety is the hallmark of emotional security. When this ‘life rhythm’ is supported by caregivers i.e. when it is synchronous, the child can attain more complex growth and development. ‘Optimal interactive regulation’ facilitates the development of more complex right brain functions of attachment security, affect regulation and a ‘burgeoning positive sense of self’ (p.387). Developmental neurobiology and psychobiology research shows that during ‘optimal’ moments of ‘bodily based affective communications’ the “primary caregiver’s exogenous sensory stimulation coincides with the infant’s endogenous organismic rhythms” (Schore, 2012, p.230).
