Abstract
The development of Isolation Peeps (IP's) was studied in seven laboratory-reared squirrel monkeys (Saimiri sciureus) over the age range of one day to two years. IP's were identified by specified criteria from the wide range of vocalizations recorded and analysed by descriptive and statistical methods. Despite the presence of substantial maturational changes in IP's, the data reveal individuality or vocal signature at all ages tested. Furthermore, the animals had developed by the end of the study unique and stable IP's comparable to those recorded previously from wild-caught adults.
