ORIGINAL PAPER

Abstract

Mindfulness meditation (MM) and EEG-alpha neurofeedback (NFB) have both been shown to improve attentional performance and increase full 8–12-Hz EEG alpha amplitude, but no studies have compared MM and NFB on their effects for modulating EEG alpha or attentional control. Sixty-one university students were randomized to a 15-min single-session MM (n = 24), NFB (n = 17), or sham-NFB (SHAM; n = 20) intervention and were compared on EEG alpha full and sub-band amplitudes during completion of a single 15-min session of either intervention across 5 successive 3-min epochs, as well as during performance of the Stroop test. MM and NFB participants demonstrated higher global full-band alpha amplitude when compared with SHAM participants during the final intervention epoch, whereas no group differences were observed for sub-band amplitudes. In the absence of group differences in behavioral performance, MM participants exhibited a lower ERD of the upper alpha-band within frontal cortex 200–400 ms post-stimulus on the Stroop task, an effect that correlated with upper alpha amplitudes demonstrated during the intervention. Future research directions are discussed.
