【abstract】
The popularity of online games has generated research interest in the flow experiences they may induce and the possibility of game addiction. Our study focuses on the dynamics of progression within online games, a perspective largely overlooked in previous investigations. Recreation specialization is used for exploring progression among online gamers and clarifying relationships between flow experiences and addiction tendencies. Data from online questionnaires completed by 357 players of Massively Multiplayer Role-Playing Games showed that specialized players are more likely to experience flow and exhibit game addiction than inexperienced players. Additionally, recreation specialization intensifies the effect of flow experiences on addiction tendencies. Our study results also demonstrate a moderating effect of recreation specialization on the flow-addiction relationship. The effect of flow experience on addiction tendency was stronger among highly specialized online game players than it was for other players.
