“…A fundamental variable concerning compensation is probably age of the infants. Locke-Haydon (1984a) drugged the father and siblings at 4 and 14 weeks respectively. Our study shows that compensation occurred mostly in the first two weeks.…”

“…In particular, Ingram (1975), cited by Locke-Haydon (1984a, p. 806), reported that when one parent carried the infant for less time than usual, the other parent would compensate by carrying more. Locke-Haydon (1984a), by contrast found that mothers did not compensate when fathers had been given a tranquilizing drug. Locke-Haydon (1984a) also developed a model predicting the conditions under which compensation would be expected to occur, and under which conditions it would not.…”

“…Locke-Haydon has shown previously that intramuscular injection of modecate into the fathers of 4-week-old infants reduces the fathers' responsiveness to their infants. Drugged fathers spend less time grooming infants, pick them up less frequently, and approach and leave their infants less often than do control fathers (Locke-Haydon, 1984). In the experiments reported here, not only the fathers, but also the mothers and older siblings of 4-week-old infants received the drug, with the intention of reducing the responsiveness of all of the infant's caregivers.…”

“…The drug used in this study was fluphenazine decanoate: a phenothiazine derivative that functions as a long-acting tranquilizer, marketed under the tradename "modecate." Further details of the drug and of its mode of action are given in Locke-Haydon (1983, 1984. Locke-Haydon has shown previously that intramuscular injection of modecate into the fathers of 4-week-old infants reduces the fathers' responsiveness to their infants.…”

Effects on the behavior of infant common marmosets (Callithrix jacchus) of separation from caregivers and of drug‐induced reduction in caregiver responsiveness

The effects of separating 4-week-old twin marmosets for 8 days from their families are compared with the effects of leaving 4-week-old infants with their families, but reducing the responsiveness of their caregivers for 8 days by administration of the tranquilizer fluphenazine decanoate. Both treatments reduce infant mobility, abolish play, and increase the time that infants spend with each other. During the period after the termination of the treatment, both treatment groups continue to play and move less than controls, and try to climb onto the mothers more frequently. These results are consistent with the hypothesis that the principal factor precipitating disturbed behaviors in infant monkeys subjected to long-term separation is disruption of the infant-caregiver relationship rather than the separation itself. Some post-treatment differences occur between separated and tranquilized groups. Notably, reunion after separation appears to involve a marked readjustment of the behavior of all family members to the return of the infants, whereas withdrawal of the tranquilizer does not.

Responses of foster-mothers and troop members to adopted newborns in a captive group of rhesus monkeys

ABSTRACT. Two rhesus monkey males and two females, born to females caged singly, were exchanged with same-sex infants born to females in a large troop which was held in an enclosure in a different building. The ages of the infants were between 24 and 120 hr. The selected foster mothers (FMs) immediately accepted the foreign infants, allowed them to suckle and treated them as their own offspring. Compared with interactions with previous offspring, the FMs initially tended to be more possessive and restrictive of their foster infants: generally they took longer before they allowed the infants to sit at a distance from them and more readily retrieved them. The foster infants tended to be more active ('fidgety') than natural (control) offspring born to the troop. Non-related members of the troop, differentiated between foster and control groups. These troop animals more frequently approached and sat in proximity, often in fur-contact with, touched, groomed, and lipsmacked to, foster infants than control infants. The attractiveness of the fostered infants seemed to be slightly associated with the FMs' dominance rank. The foster infants were therefore viewed by others as having assumed the role afforded by the FMs' rank. Thus both FMs and other troop members recognized the unfamiliarity and novelty of the foster infant but the infants were still accepted into the group. We suggest that the different treatment of the foster infants by the troop may have consequences on the infants' future social development.
