Supplemental Material for Does it pay to play? Undermining effects of monetary reward and gamification in a web-based task.

The increasing use of self-paced computer and web-based platforms for e-learning work has led to renewed interest in promoting intrinsic motivation. A classic finding motivation literature is the undermining effect: Task reduced when previously presented monetary rewards are eliminated. Efforts prevent effects on tasks have focused adding game-like features, such as points or leaderboards (i.e., “gamification”), maintain task interest. On other hand, some raised concern that these game elements could be a reward undermines motivation, engagement features We, therefore, conducted two preregistered studies pay gamification memory task. Results revealed small effect performance incentives were removed from Exploratory analyses suggested slightly different mechanisms behind each type effect. Finally, we observed large benefits performance-based rewards, relative alone. Implications explanations application online learning contexts discussed.
