a Experimental order and alpha power. Participants undergoing the control period followed by the meditation period tended to evince greater alpha power during meditation, whereas those undergoing the meditation period followed by the control period tended to evince greater alpha power during the control period. b Meditators with less than 5 years of daily meditation practice (n = 6, M = 2.5, SD = 1.4) vs. meditators with 10 and greater years of daily meditation (n = 10, M = 19.3, SD = 8.5) practice showed different tendencies with regard to alpha power across experimental sessions, with shorter-term practitioners showing a trend toward greater alpha during meditation and longer-term practitioners showing the opposite pattern
