Training Working Memory in Adolescents Using Serious Game Elements: Pilot Randomized Controlled Trial

Serious game elements serve as a mechanism to enhance engagement and training intensity in cognitive interventions, specifically regarding working memory capacity in adolescents. By comparing gamified training against standard and placebo conditions, this research evaluates whether the integration of game mechanics can improve both participant adherence and cognitive outcomes. The primary thesis posits that while gamification effectively increases initial motivation and the volume of completed training sessions, these benefits are often transient and fail to produce superior cognitive gains compared to traditional training methods.

The study, which involved 84 adolescent participants, reveals that gamified interventions successfully drive higher participation rates and increased trial completion in the short term. However, data indicates that the motivational impact of these game elements diminishes as the training progresses, suggesting that extrinsic rewards may be insufficient for sustaining long-term interest. Furthermore, the analysis shows no significant variance in working memory capacity improvements across the different conditions, indicating that the addition of game mechanics does not inherently enhance the efficacy of the cognitive training itself.

These findings highlight a critical challenge in the design of serious games for developmental and clinical applications. While gamification is a viable tool for boosting initial engagement and training intensity, the decline in participant interest over time underscores the necessity for more sophisticated, immersive design strategies. Future efforts must focus on better managing participant expectations and developing more robust motivational frameworks to ensure that the benefits of gamified cognitive training are maintained throughout the entire duration of an intervention.
