“…Thus, for example, the control of physiological arousal, which is achieved during early infancy and underlies mastery of state regulation and control of sleep-wake cycles, eventually becomes integrated into the processes of attention engagement and disengagement (Porges, 1996;Richards, 1985Richards, , 1987. Moreover, attentional control becomes integrated into emotional and behavioral regulation (Belsky, Friedman, & Hsieh, 2001;Rothbart, Posner, & Boylan, 1990;Sethi, Mischel, Aber, Shoda, & Rodriquez, 2000). In our view, these early developing levels of regulation-physiological, attentional, and caregiver-supported emotional regulation-play a critical role in very early personality and social behavior, and these early emerging behaviors will be reciprocally involved in the development of more complex levels of regulation, such as those involved in behavioral control, interpersonal processes, and metacognitions (Cole, Michel, & Teti, 1994;Stifter, Spinrad, & Braungart-Rieker, 1999).…”
