Mother-infant separation in squirrel monkeys living in a group.
Two female and three male infant squirrel monkeys (Saimiri sciureus) were separated from their mothers at a mean age of 169 days. All had been reared from birth in a large communal cage. The experiment consisted of three five-day periods: (1) preseparation baseline, (2) separa tion > and (3) reunion. Throughput the experiment, each in fant was observed for ten minutes per day. Frequency and d...
متن کاملSocial recovery by isolation-reared monkeys.
Total social isolation of macaque monkeys for at least the first 6 months of life consistently produces severe deficits in virtually every aspect of social behavior. Experiments designed to rehabilitate monkeys reared in isolation are described. While young isolates exposed to equal-age normal peers achieved only limited recovery of simple social responses, some mothers reared in isolation even...
متن کاملConceptual numerousness judgments by squirrel monkeys.
Two monkeys were reinforced for responding to the card which displayed fewer number of entities (three randomly selected sizes of filled circles) than the other card in any given pair. Area and brightness cues were controlled (at least for the successive numerousness discriminations), as were specific-pattern learning cues. Training proceeded in the order 2 versus 7 (2:7), 2:6, 2:5...2:3, 3:7, ...
متن کاملCup tool use by squirrel monkeys.
Captive-born male and female squirrel monkeys spontaneously 'invented' a cup tool use technique to Contain (i.e., hold and control) food they reduced into fragments for consumption and to Contain water collected from a valve to drink. Food cup use was observed more frequently than water cup use. Observations indicate that 68% (n = 39/57) of monkeys in this population used a cup (a plastic slip ...
متن کاملSociophysiology of Squirrel Monkeys
Primate sociophysiology is an emerging discipline concerned with understanding the proximate mechanisms that contribute to the generation and maintenance of species-typical social systems. Studies of squirrel monkeys illustrate that sociophysiological processes are more varied than is commonly assumed with respect to both the effective social dimensions that influence physiological function and...
