ABSTRACT
The major theme of our chapter is that cultural context is a source of ontogenetic continuity from birth to maturity. Our case in point is development among the Zinacantecos, an endogamous Mayan Indian society in Chiapas, Mexico (Vogt, 1969). We trace two aspects of behavioral style that are constant in Zinacanteco development from birth to maturity: (a) restrained motor activity and (b) the tendency to respond (rather than initiate).
