Adequate mothering by partially isolated rhesus monkeys after observation of maternal care
van Vreeswijk, W.
13 laboratory-born female monkeys were allowed to remain with their mothers for about 4 mo and were subsequently singly caged in rooms where they were able to see other monkeys. Ss that did not see mothers caring for their infants neglected their own firstborn. In contrast, Ss that were allowed to observe separately caged mother–infant pairs accepted their own infants but initially held them in atypical positions. Only 2–3 yrs of natural group life, which probably involved observation of mothering and carrying younger group members, led to acceptance as well as normal holding postures. Results indicate that visual exposure to maternal care, which must take place when the animal is older than about 4 mo, leads to acceptance of the neonate. However, subsequent tactual experience is usually required for learning to hold the infant properly. (8 ref) (PsycINFO Database Record (c) 2012 APA, all rights reserved)
