Percussive manipulations distinguish object play in capuchin and patas monkeys
Object play has been proposed as a developmental precursor of flexible tool use. We applied a standardized object play protocol, previously used with corvids and parrots, to tufted capuchin monkeys (Sapajus apella), a member of a genus known for tool use, and patas monkeys (Erythrocebus patas), for which tool use has not been reported.
