“…Nine male rhesus monkeys (Macaco, mulatto) were equally divided into 3 groups: a wild-born (WB) group, housed singly from their arrival in the laboratory at an estimated age of 8-12 months and 2 lab-born groups, separated from their mothers within the first 2 days post-partum and raised in individual cages with identical cloth surrogates. The surrogates of one group (SS) occupied a fixed position within the cage, whereas those for the other (MS) moved up and down and around the cage on an irregular schedule (see Mason & Berkson, 1975, for further details).…”

“…The monkeys were maintained in individual cages, except for testing. Prior to this experiment, social interactions for lab-born monkeys were limited to a series of paired encounters beginning when they were approximately 14 months old and totaling 5.5 hr of social exposure, equally divided between male and female wild-born companions (Mason & Berkson, 1975). Some of these same wild-born monkeys were used in the present research.…”

The social behavior of rhesus monkeys raised for the 1st year of life with mobile (MS) or stationary (SS) cloth surrogate mothers was investigated when the animals reached 4-5 yr of age. The MS males generally refrained from social interaction during initial pairings with females, whereas SS males interacted frequently, but were more often the targets of attacks and chases from adult females than were MS males. The MS males were more likely to vary their social behavior according to the behavior of the social partner and seemed to benefit more from extended social exposure than their SS counterparts. The MS females were more similar to wild-born females than were SS females in nearly every behavior category and dimension tested. These results suggest that rearing with mobile artificial mothers improves the chances of later adaptive social adjustments in socially restricted monkeys.Early restriction of social contacts can produce a broad spectrum of deficiencies and aberrations in the social behavior of rhesus monkeys (e.g

229Summary Fifty-two cynomolgus monkeys were reared in peer groups on surrogate mothers and fed by bottle during the first months of life. A description of the technique of bottle feeding and the structure of surrogate mothers is presented. Results are shown in a growth curve. Interindividual differences in body weight were very large. The mean weight was higher in males than in females, but no significant sex differences in growth occurred. The weight of mother-reared infants stayed within the standard deviation of the mean weight of the artificially-reared subjects.

“…However, these surrogates required either large housing areas or cumbersome external machinery (Anderson et al, 1977;Mason & Berkson, 1975;Duijghuisen et al, 1992). Such requirements cannot typically be met in contemporary nurseries, which often require individual infant housing.…”

A biological mother's movement appears necessary for optimal development in infant monkeys. However, nursery-reared monkeys are typically provided with inanimate surrogate mothers that move very little. The purpose of this study was to evaluate the effects of a novel, highly mobile surrogate mother on motor development, exploration, and reactions to novelty. Six infant rhesus macaques (Macaca mulatta) were reared on mobile hanging surrogates (MS) and compared to six infants reared on standard stationary rocking surrogates (RS) and to 9-15 infants reared with their biological mothers (MR) for early developmental outcome. We predicted that MS infants would develop more similarly to MR infants than RS infants. In neonatal assessments conducted at day 30, both MS and MR infants showed more highly developed motor activity than RS infants on measures of grasping (p=.009), coordination (p=.038), spontaneous crawl (p=.009), and balance (p=.003). At 2-3 months of age, both MS and MR infants displayed higher levels of exploration in the home cage than RS infants (p=.016). In a novel situation in which only MS and RS infants were tested, MS infants showed less of a stress response, spending less time near their surrogates in the first five minutes of the test session than RS infants (p=.05) and exhibiting a significantly lower rise in salivary cortisol after the test than RS infants (p=.018). Collectively, these results suggest that when nurseryrearing of infant monkeys is necessary, a mobile hanging surrogate may encourage more normative development of gross motor skills and exploratory behavior and may serve as a useful alternative to stationary or rocking surrogates.
