Infrequent non-target tone event-related potential responses
*At the Cz site, there were significant changes in amplitude in N1 and P3 responses to infrequent non-targets as well as a group effect for N1 responses, with meditators showing higher amplitudes during the Tones task, p = .02. There was an additional group effect for P2 with meditators showing higher amplitudes during the Breath Counting task, p = .04.
