Zusammenfassung:The investigation of the infant's simple and conditional discrimination learning demands an experimental planning that involves variables and appropriate situation features to population peculiarities. It was described the performances in discrimination tasks of four 12 until 24 month old infants in relation to: discrimination tasks, general conditions of the experimental procedure--to play between attempts; to play after sessions' conclusion; attempts' number or correct responses to reach learning criterion. The infants participated in one of two experiments, in a daycare center, where one apparatus to teach discrimination were located. Constant analysis of the participants' behavior allowed identifies relations between the infants' responses and the nature of the social contact with the experimenter and the variety of stimuli with functions predicable or not in experimental planning. The manipulation of selected variables produced: the expansion of the infants' time in the experimental situation; the increase of the infants' responses directed to the apparatus and the increase of infants' correct choices. Key words: simple discrimination; conditional discrimination; identity matching; infants; experimental studies. A investigacao sobre a aprendizagem de discriminacoes simples e condicionais por bebes requer um planejamento experimental com variaveis e caracteristicas da situacao apropriadas as peculiaridades da populacao. Foi descrito o desempenho de quatro bebes de 12 a 24 meses em relacao a: tarefas de discriminacao, reversao e remediativos; condicoes gerais dos procedimentos experimentais--brincadeiras entre tentativas; brincadeira apos o encerramento da sessao; numero de tentativas por sessao ou de respostas corretas para atingir o criterio de aprendizagem. Os bebes participaram de um entre dois experimentos em uma creche onde foi instalado um aparato para ensino de discriminacao. Analises continuadas do comportamento dos participantes permitiram identificar relacoes entre as respostas deles e a natureza do contato social com experimentador e a variedade dos estimulos com funcao prevista ou nao no planejamento experimental. A manipulacao das variaveis selecionadas produziu: aumento do tempo de permanencia dos bebes na situacao; aumento das respostas dos bebes direcionadas ao aparato e o aumento do numero de acertos. Palavras-chave: discriminacao simples; discriminacao condicional; pareamento de identidade; bebes; estudo experimental.
