Abstract
We developed and tested four sonic games responsive to changes in EEG band power. 26 participants in four studies played the neurofeedback games, encouraged to find their own strategies to control the specific neurofeedback parameter. Mixed method analysis of performance in the games and post-session interviews where the probands described what strategies they used, led to the identification of subjective mental states that correlated with success in the game.
One of the principal findings of the series of studies is that increase in left frontal beta activity was facilitated by evoking interest in observed surroundings (in contrast, inner counting or planning of quotidian tasks did not lead to an increase in the band power). Currently, an experiment is taking place to validate this finding.
