Vocalizations between pairs of adult female “Gothic-arch” squirrel monkeys were tape-recorded, along with identification of the vocalizer and social context. The major purpose the study was to identify and describe acoustic characteristics of cer
Communication is both a prerequisite and manifestation of social organization and in this sense several chapters of this volume are aimed to investigate the way vocal communication serves its ultimate function of maintaining social organization. Alth

The responses of 256 single neurons in the medial geniculate body of awake squirrel monkeys have been examined with a variety of acoustic stimuli. Both traditional artificial sounds and tape-recorded tokens of species-specific vocalizations were empl

Isolation calls of captive squirrel monkeys were recorded by separating infants from their natal group members and then permitting vocal contact between the "lost" baby and the group at systematically varied distances. Separated infants gave longer c

Isolation peeps (IP's) made by captive squirrel monkeys (Saimiri sciureus) of both the Gothic and Roman type have been analysed by spectrographic and statistical methods designed to quantify the degree of individuality found in utterances from single
