Selection Of

5 infants were observed during the first 13 mo. after birth in a free-ranging group of Japanese monkeys ( Macaco fuscata) to examine whether they maintained relatively frequent affiliative relationships with particular immature individuals. The number of immature affiliative partners rapidly increased from the first 3-mo. period after birth to the second 4-mo. period after birth, and the infants thereafter maintained affiliative relationships with particular individuals, mostly same-aged infants, at least in the second half of their first year. These findings show that infants were likely to interact with a larger number of different animals in the early stage of development, and thereafter selected particular individuals with whom they maintained affiliative relationships. The effects of sex on the selection of these long-term partners are also discussed.

Abstract1. Responsiveness to inanimate objects was studied in feral M. fuscata by: (a) observing reactions to naturally occurring objects, (b) placing novel toys along paths and on rocks, and (c) presenting novel dolls in conjunction with food, as in a conflict test. 2. Spontaneous manipulation seemed less frequent and less persistent than in laboratory primates. Children accounted for a vast majority of such activity. The dominant modes of reaction to novel objects were cautious in nature, albeit avoidance was often impossible to observationally distinguish from indifference, especially in adult males. Emotional displays were rare, presumably because of Ss' ability to make spatial adjustments and thus control the effective intensity of stimulation. 3. The larger a doll, or the closer it was to a food kettle, the fewer and the farther the approaching monkeys. With time more Ss began to approach, but adaptation was slow. 4. The data were discussed in relation to problems of social behavior and instrumentation, and to the general problem of measuring responsiveness in the laboratory and the field.
