We recently reported that a left-right asymmetry index for peak alpha frequency (PAF) had asignificant correlation with the mean log-transformed produced duration (r = .36, n = 51, p< .01) of individuals completing a time-production task with online EEG recording(Glicksohn et al., 2009). The sample in that study comprised 27 participants serving in acondition of restful wakefulness, and 24 participants participating in a session of motortraining. In the present paper, we add to this data set a group of 47 meditators—31 long-term(LT), and 16 short-term (ST). For the LT meditators, we report that the left-right asymmetryindex for PAF has a significant negative correlation with the mean log-transformed producedduration (r = -.41, p < .05), indicating a reversal in asymmetry. We discuss the relationshipbetween PAF and time production, drawing implications for the rate of functioning of aninternal clock.
