not their hands, as they would in video game play. Subsequent to balloon selection on each trial, feedback was delayed variably between 1000 and 1200ms. This was done to make the task feel less monotonous and to mitigate against the possibility of a contingent negative variation (CNV) in the EEG signal. Feedback lasted 1000 ms followed by a 1000-1200ms crosshair, and a 100ms blank screen before the balloons reappeared. Participants' selection of a balloon was self-paced on each trial.
