The aim of this study is to explore the relationships between experienced immersion and autotelic engagement in computer gamers. As the tendency to act for the sake of acting or not, autotelic v/s exotelic engagement makes the gamer more or less susceptible to experiencing immersion. The interdependence of experiencing immersion and the sense of autotelic engagement corresponds to the level of autotelic immersion. Students from different university majors (N=87) participated in the study. They completed 2 questionnaires: The Immersiveness Inventory (ING) and the Engagement Questionnaire (FLOW). The results of this study indicate that the experience of autotelic immersion is enhanced by autotelic engagement, manifesting autotelic cognitive properties during computer game playing. In such cases, Interaction with the environment, Sensory Engagement, Sense of Control, balance between ability level and challenge, intrinsic rewarding, concentrating and focusing, control, feedback, and action awareness merging intertwine with each other. Strong positive correlations of interaction with the virtual environment and sense of control were observed with all dimensions of autotelic engagement: the balance between ability level and challenge, loss of the feeling of self-consciousness, clear goals, intrinsic rewarding, concentrating and focusing, control, and autotelic experience. There is a strong directly proportional relationship between autotelicity and immersion.
