The spontaneous use of tools by capuchin monkeys (Cebus sp.) has been studied by the Cognitive Ethology Laboratory in wild and semi-free groups. In the Tietê Ecological Park, the use of stones for cracking jerivá (Syagrus romanzoffiana) nuts has been a target of naturalistic studies for more than a decade. Recently, we also started to study this behavior through "experimental interventions" to enhance our understanding about several aspects of the selection and transportation of the tools usedby these animals. The studies here proposed give continuity to these experiments, evaluating theway the monkeys "organize" the use of tools. (AU)
