The study aimed to examine whether there is an effect of playing a violent video game on reducing prosocial behavior, compared to playing prosocial and neutral video games. The study involved 105 participants, who were randomly assigned to one of three groups: playing a prosocial, violent or neutral video game. Before playing the game, participants answered the following questionnaires: Demographic data questions, Questionnaire about playing video games, and Questionnaire about prosocial behavior. After they finished playing the video game they were given a tangram task as a measure of prosocial behavior. The hypothesis was that there was going to be a negative impact of violent video games on prosocial behavior, meaning that participants who played a violent video game would have the lowest score on the measure of prosocial behavior, but the research results showed that there was no significant difference between the groups. This result meant that there was no confirmation of the negative impact of violent video games on prosocial behavior. Also, the hypothesis of a statistically significant negative correlation between the time spent playing video games and prosocial behavior was not confirmed. The obtained results did not confirm the hypotheses that were set. In conclusion, we could say that the results predicted by the hypotheses were not obtained and that it is necessary to include more diverse types of video games, ways of playing, players and non-players in future research in order to explore this topic more deeply.
