The development of simple, nonsocial behaviors was observed in neonatal squirrel monkeys and cotton‐top tamarins. One group of observed behaviors included rooting, orienting up, clasping, and grasping, and was assumed to be more directly related to maintenance of maternal contact and nursing than others such as visual and auditory orienting, crawling, walking, and climbing down. Comparison of the results with previously reported data from rhesus monkeys and galagos supported the hypothesis that neonatal behaviors related to maternal contact and nursing persist longer in species with relatively passive maternal behaviors than in species with relatively active maternal behaviors. In contrast, the development of neonatal behaviors not directly related to maternal contact and nursing was not found to vary reliably as a function of species.
