摘要: This study investigated the influence of social rearing on ultrasonic vocalization (USV) responses 11- to 12-day-old rat (Rattus norvegicus) pups in isolation presence or removal an anesthetized adult. Pups were reared with dam plus a virgin female (aunt), their biological sire, castrated male. All reduced rates USV contact adults. Pups' after adult's depended experience. After dam, increased over baseline (potentiation). aunts potentiated adult females but suppressed males. sires strange males did not suppress castrates unfamiliar intact Thus, pups' differential passive adults can be acquired during prior
