The present study was conducted according to the Freudian subdivisions on human psychosexuality. The study on sexuality can be subdivided and directed to several themes, walking through several areas of knowledge, where each theoretical field contributes significantly to such study. This work was part of the studies of the discipline Human Sexuality of the Course of Psychology of the Federal University of Rondônia in the second semester of 2017 and reports an observation made with four children, having as subjects children in the age group of 3 to 8 years, whose names used in this Freud's contributions to human sexuality, with emphasis on the phallic phase and latency period, are fictitious and based on theory. To assist in the field observations on the phases, a plan of observations was made with a script of aspects to be observed considering the literature that already indicates some characteristics attributed to this stage of human life. As a result, it was observed that there are clear correspondences between the literature and the practice, however, there is a need to broaden the means and resources of observation to deepen the research, producing, in turn, a better analytical apparatus.
