This research intends to investigate the acquisition in Brazilian Portuguese of the three types of perfect, proposed by Pancheva (2003), associated with the present tense, assuming the existence of syntactic node(s) of perfect in the structural representation of the sentence. Based on this investigation, we aim to contribute to the study of the representation of linguistic knowledge of perfect. The hypothesis of this research is that the emergence of the resultative perfect, experiential perfect and universal perfect associated with the present tense occurs simultaneously in the Brazilian Portuguese acquisition. To this end, we developed a case study, with speech data longitudinally retrieved from a child in the process of acquiring Brazilian Portuguese. The obtained data revealed the following order of realization of the perfect types: resultative perfect, universal perfect and experiential perfect. This way, we refuted the hypothesis of this study. Thus, we suggest that there is a dissociation in the linguistic representation of these types of perfect, each one of them projecting, respectively, the nodes RePerfP, UPerfP and ExPerfP. The features heading these projections would be, respectively, resultative, continuous and experience. We also argue in favor of the following structural hierarchy: ExPerfP > UPerfP > RePerfP.
