  Fathers have higher motivation for parenting than mothers in common marmoset (Callithrix jacchus)
■ 概要
  We adopted the infant-retrieval test to compare the motivation for parental or alloparental behaviour among family members. All the fathers invariably retrieved their infants promptly, but some mothers did not. This variation of responsiveness of mothers was partially explained by the amount of their experience of having their own infants. There was a tendency that inexperienced mothers took a longer time to retrieve infants than experienced ones. Older siblings took a significantly longer time to retrieve infants than fathers during the first few days, but their latency became the same as that of parents in the 8-day test period.
