Do people perceive time differently during meditation? In order to assess the differing effects of two styles of meditation (mantra vs mindfulness) on subjective time perception and electroencephalographic (EEG) recordings, 14 experienced meditators were recruited for this repeated-measures experiment and examined during 3 conditions in Shove Memorial Chapel. To assess subjective time perception during meditation a temporal bisection task was administered before the meditation session, and two times during the session. EEG recordings were obtained using a 3D-printed OpenBCI Ultracortex MarkIV with dry comb-style Ag-AgCl electrodes. The EEG data were gathered to assess 1) if there are differences between the brainwaves of people practicing different styles of meditation, and 2) as a way to make sure that the participants actually were meditating. Preliminary analysis shows large variation between individuals and their differing responses to each condition. However, on average the Mantra meditation condition shows the highest power within alpha frequencies (7-12 Hz), followed by Mindfulness and then Control. Within the beta frequency (12-25 Hz) both meditation conditions show greater power than the control condition. Statistical analyses of the temporal bisection data and EEG data are forthcoming.
