The nature of social context as a factor affecting grouping behavior is experimentally examined in captive groups of squirrel monkeys by recording the effects of systematic removal and return of individuals on the distributions of non-agonistic interactions and prolonged (huddle) contacts among the remaining group members. Observed changes in the(More)
The structure of social attraction was assessed in pair- and group-living squirrel monkeys (Saimiri) using paired-comparison and single-stimulus preference tests. Effects of the social environment were most prominent in females. Females housed with a single male showed sharply increased attraction to like-sex strangers and less pronounced increase in(More)
Various classes of individuals were removed from three captive groups of squirrel monkeys and effects measured on the frequencies of nonagonistic interactions of the remaining individuals. Results indicated that there are regularities in the effects of certain classes of dyadic relationships on others which may be considered species-typical structuring(More)
