Conditions of observation and social distance in groups of squirrel monkeys,Saimiri sciureus

  • Fernando Alvarez


Observation conditions were very influential in determining the social distance among members of groups of squirrel monkeys.

With observer visible to the animals and recording by talking into a tape recorder the monkeys did not show a consistent pattern of social distance as reflected by actual space and frequency of bodily contacts, whereas when the observer was concealed, looking through a one-way vision screen and recording silently by marking on paper, the subjects tended to group in unisexual clusters, with that of the females showing higher cohesiveness.
