      Nossa pesquisa tem como objetivo estudar o desenvolvimento dos infantes e juvenis de um grupo de macacos-prego (Cebus apella) em condição de semiliberdade, com ênfase nos comportamentos manipulativos. No presente estudo, relacionamos o aparecimento do uso de instrumentos para quebra de cocos com a brincadeira social e com a brincadeira com objetos. A brincadeira social ocorreu predominantemente em infantes e juvenis. A brincadeira com objetos, muitas vezes indistinguível das atividades exploratórias, aumentou durante o primeiro ano de vida. A manipulação exploratória de pedras constitui uma oportunidade importante para a aprendizagem individual, por tentativa-e-erro, do uso de instrumentos para quebrar cocos, que surge entre o segundo e o terceiro anos de vida. A brincadeira social parece facilitar a tolerância entre os sujeitos, o que favoreceria a aprendizagem por observação dos episódios de quebra.

      Translated abstract

      The aim of our research is the study of the development of young tufted capuchin monkeys (Cebus apella) from a semi-free group, with an emphasis in manipulative behaviors. In the present study, we discuss the relations between the appearance of tool-use in nutcracking and social and object play. Social play occured mainly among infant and juvenile subjects. Object play is often indistinct from exploratory activities and increased during the first year of life. The appearance of the use of tools for cracking nuts, between the second and the third year, is related to exploratory manipulation because of its importance for trial-and-error learning. Social play may facilitate tolerance among subjects and hence favour the observational learning of nutcracking.
