Individualized Alpha Neurofeedback for ADHD

Real time visual feedback will be given the participants, such that as the higher/lower alpha power increases (relative to the mean value in the pre-training resting state EEG recording) a plane on the screen will move horizontally (the movement is correspondent to the magnitude of upper/lower alpha ratio), and the animation will change based on EEG parameter every 2 seconds. EMG-based feedback is also provided, such that if the children's EMG level is too high the plane will drop (vertical movement). Participants are instructed to 'fly' the plane as far as possible.

The sham neurofeedback protocol was identical to the verum neurofeedback protocol except that the animation (horizontal plane movement) was based on the EEG results of another participant. EMG-based feedback will still be provided for the sham condition
