This study investigated the influence of social rearing on ultrasonic vocalization (USV) responses of 11- to 12-day-old rat (Rattus norvegicus) pups in isolation to the presence or removal of an anesthetized adult. Pups were reared with the dam or dam plus a virgin female (aunt), their biological sire, or a castrated male. All pups reduced rates of USV in contact with anesthetized adults. Pups' USV rates after the adult's removal depended on their rearing experience. After removal of the dam… CONTINUE READING
