Vocal Ontogeny in Macaques and Marmosets: Convergent and Divergent Lines of Development

摘要: Of the many published studies of behavioral development in non-human primates (NHP), very few have had a comparative emphasis which developmental course behavior found two taxa is compared. Where comparisons been made, they consist rather broad leaps between taxa, such as NHP and songbirds or humans (e.g, Snowdon et al., 1986). The these on emergence apparently similar behaviorally relevant phenomena imitative learning. Within literature NHP, individual species are becoming increasingly prominent, particularly for do well captivity can, therefore, be observed great detail from birth. Communicative behavior, vocalizations, come under close scrutiny several species, and, with availability instruments can graphically represent vocalization time-histories (sound spectrographs related forms time history displays), some details species’ vocal repertoire being documented. One group squirrel monkeys (Saimiri), has studied over more than twenty years, considerable information about now available (see contribution by Biben, this volume). Representatives other primate groups, genus Macaca callitrichids (marmosets tamarins) also subjects detailed analyses development. Interestingly, both efforts made to demonstrate an important role learning acquisition communication skills (macaques: Gouzoules Gouzoules, 1989; Masataka Fujita, callitrichids: Elowson 1992; al.,1986). While controversial, pioneering kept alive hope among primatologists that model studying language human children may yet found.
