Outline of Final Research Achievements

We conducted research with the aim of clarifying the mechanisms of play and the factors that inhibit it, based on the thesis that "enjoyment," which is an element of playability, is different from "pleasure," which leads to the danger of dependence. The primary issue is the structure of the DG, which is designed to be sustained for long periods of time. Furthermore, a decrease in alpha-2 waves was observed in the group with gaming addiction following a stress task. In severe cases of gaming addiction, brain fatigue accumulates due to the sustained concentration of momentary focus. There is a possibility that specific changes in brain function related to addiction are occurring.

Academic Significance and Societal Importance of the Research Achievements

本研究では、遊戯性の要素である「楽しさ」と「依存への危険を導く快」が異なるというテーゼに立ち、ゲーム依存のメカニズム及びそれを抑制する要因を明らかにすることで、GAの予防の一助となる成果に至ることを目的とする。質問紙調査及び実験での検証より、青年期特有の心理状態のアセスメント、脳波や唾液中生化学成分の生物学的エビデンスをも含めた総合的なGAメカニズムの解明を試みた。本研究の将来性として、GA予防の方策及び依存症治療後におけるセルフコントロールによる再発防止法の開発までの発展が可能と考える。
