Participants
24 (12 experienced meditators, 12 non-meditators)
Population
Adults
Protocol
Twin Hearts guided meditation; P300 event-related potentials
Sessions
1 guided meditation session

Key findings

  • At baseline, experienced meditators had shorter P300 latency at Fz and Cz
  • After one session, non-meditators showed larger P300 amplitude at Fz, Cz and Pz
  • Experienced meditators showed no significant change after the session
  • All measures moved in the direction of more efficient processing; small sample (24)

Twelve people with at least 1000 hours of practice in this guided compassion meditation were compared with 12 non-meditators, with the auditory P300 brain response recorded at three midline sites before and after listening to the meditation. Experienced meditators started with faster P300 responses, and non-meditators showed larger P300s right after the session. The authors read this as a quick cognitive boost in newcomers and more stable benefits in long-term practitioners, though the sample was small.
