Abstract

In the guinea pig, the presence of the mother, but not littermates, has been found to inhibit hypothalamic-pituitary-adrenal (HPA) responses during brief (30-60 min) exposure to novel surroundings both prior to and several weeks following the completion of weaning. in the present study, we found that an unfamiliar adult female inhibited plasma cortisol and vocalization responses of pre- and postweaning guinea pigs during a till-min exposure to anovel environment. However, the presence of the mother still had a greatereffect on the cortisol levels of the young, at least during the preweaningperiod. The moderating influence of the unfamiliar adult female on vocalizations and cortisol levels occurred despite behavioral interactions, such as heightened aggression and sexual behavior, not seen during tests with themother. It is suggested that the unfamiliar adult female's effectiveness in reducing HPA activity during exposure to novelty may facilitate the change in patterns of social interaction occurring in recently weaned animals.
