Whether common marmosets (Callithrix jacchus) exhibit spontaneous alternation behavior was examined. Marmosets were allowed to explore one of the two arms of a Y-shaped maze, and after delays of various lengths, their preference to enter the previous

Early development of visual behavior was examined in hand-reared (HR) and parentally reared (PR) common marmosets (Callithrix jacchus). On the day of birth, most of the marmosets exhibited sensitivity to light and sound: they closed their eyes in res

Common marmosets vocalize phee calls as isolation calls, which seem to facilitate their reunion with family groups. To identify multiple acoustic properties with different time courses, we examined acoustic modulations of phees during different socia

Marmosets exchange two types of calls: phees and trills. We played back phees and trills to investigate the temporal rules of vocal exchanges using ten captive common marmosets (Callithrix jacchus). The marmosets usually emitted the same type of voca
