Or08-3the Influence of Prepotent Response Inhibition and Decision Making on Problematic Online Gaming

During the last decade, Massively Multiplayer Online games (MMO) have gained a particular interest. With dozen of millions users playing every day, the prevalence rate for the excessive and problematic usage of MMO is varying from 5 to 15%. Defined in the DSM-5 as Internet Gaming Disorder, the negative repercussions on health and on both family and professional spheres can be heavy. Several studies have highlighted the role of impaired inhibition capacities on the onset and maintenance of problematic behavior. More specifically, the inhibition of prepotent response identified and defined by Friedman and Miyake (2004) as the ability to deliberately suppress automatic behaviors has been reported impaired among excessive players. Another cognitive mechanism that was related to excessive online gambling is decision making abilities. It has thus been proposed that excessive gamers have difficulties to balance short term benefits with future outcomes (e.g., neglecting relationships) The aim of our study is to compare inhibitory control and decision making skills in problematic and non-problematic gamers (previous studies often compared problematic gamers with non-gamers). A secondary objective of the study will be to compare proportion of problematic versus non-problematic players according to the main types of MMOs (MMORPGs, FPS, MOBA).
