Examining the Impact of a Specific Guided Meditation (Twin Hearts Meditation; THM) on Mood, Cognitive Functioning, and EEG Dynamics in Experienced and Novice Meditators

Detailed Summary

The goal of this clinical trial is to examine the impact of a specific guided meditation (Twin Hearts Meditation; THM) on cognitive functioning and EEG dynamics in experienced and inexperienced meditators. The main questions it aims to answer are: * Will the experienced meditators outperform inexperienced meditators on the attention control tasks (Flanker, Trails A \& B) at baseline (pre-meditation)? * Will both groups show improvements in performance after meditation associated with mood and physiological state changes? * Will the experienced meditators show an overall mood profile of higher positive mood states and less negative mood states (Brunel Mood Scale subscale difference) at baseline (pre-meditation)? * Will both groups show mood state improvements after meditation? * Will the experienced meditators show differences in electrophysiological characteristics compared to inexperienced meditators? * Will inexperienced meditators exhibit shifts from their baseline resting-state EEG towards being more similar to the EEG characteristics of experienced meditators at baseline? * Will experienced meditators demonstrate differences in P300 latencies and amplitudes on the auditory oddball paradigm. Participants will: * Take a series of pre-meditation surveys. * Complete pre-meditation P300 auditory oddball task. * Complete pre-meditation cognitive behavioral task set. * Continuous 19-channel EEG recording before and after pre-recorded guided THM. * Take a series of post-meditation surveys. * Complete post-session P300 auditory oddball task. * Complete post-session cognitive behavioral task set.
