The effect of game mechanics and financial incentive on amount of engagement with a cognitive test

This study explored the effects of both game mechanics and financial incentive on the amount of engagement with a cognitive test. Participants (n = 96) signed up to take part. We used a mixed design with participants completing three test sessions over a five-day period. Each session consisted of a different SST variant (Non-Game, Points and Theme) followed by two short questionnaires on subjective engagement with the task.
