The newborn infant is a social organism, pre-disposed to interact with his caregiver and able to elicit the kind of caregiving necessary for successful adaptation. The earliest developmental task of the newborn is to organize behavior to be able to play an active role in influencing the caregiving environment and eliciting the kind of support needed for development. This task is accomplished through the attainment of self-regulation or balanced neurobehavioral functioning of the infant's autonomic, motor, state, and responsivity behavioral dimensions as described by Als.
