Recent studies show that Working Memory (WM) can be influenced by several factors. One of these factors may be the use of video games, which may be associated with cognitive gains and better WM performance. In this sense, an experimental study was developed with the objective of evaluating the influence that different types of video games have on the WM of university students, seeking to compare 3 groups of students who play different genres of video games: Action, RPG and Strategy. The main hypothesis guiding the study was: the group of students who play Strategy games has better results in the WM test than the other groups. For this, an initial questionnaire was used to collect the sample and collect sociodemographic data and data related to gaming habits, with the sample consisting of 42 students, 23 of the male gender and 19 of the female gender, aged between 18 and 25 years old. Then, the in person test, developed in SuperLab 5, was scheduled to evaluate the WM performance of the participants. It was found that Strategy game players presented shorter reaction times, as well as shorter duration of the experience, with higher accuracy rates in all stimuli, compared to Action and RPG players, which indicates a superior WM performance. It is expected that this study will contribute to the construction of other more robust scientific studies, as well as help fight stigmatization of video games
