EEG signatures of mindfulness-based artistic-contemplative sound interventions: a pilot study on aesthetic states of consciousness.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Mindfulness-based artistic-contemplative interventions, including auditory "sound pills," have increasingly been investigated using neurophysiological measures such as electroencephalography (EEG) to promote psychological well-being and attentional regulation. However, the neurophysiological mechanisms underlying these interventions remain poorly understood. Methods: This pilot, exploratory, within-subject proof-of-concept study investigated the neurophysiological effects of mindfulness-based artistic-contemplative sound pills in adults using EEG. Twelve participants were exposed to structured auditory interventions integrating poetic narratives, soundscapes, and mindfulness instructions. EEG activity was recorded before, during, and after the intervention, and spectral power across frequency bands was analyzed using linear mixed-effects models. Subgroup analyses by artistic modality (visual arts, dance, music, and theater) were also performed. Results: At the group level, exploratory analyses indicated a statistically significant modulation of high-frequency beta activity (20-30 Hz), characterized by a reduction during the intervention compared to the pre-intervention baseline, followed by a return toward baseline levels in the post-intervention phase. No statistically significant global changes were observed in the other frequency bands examined, including alpha (8-12 Hz), theta (4-8 Hz), delta (0.5-4 Hz), mu, low-frequency beta (12-20 Hz), and the combined theta + alpha band. Subgroup analyses by artistic modality suggested descriptive, modality-specific oscillatory patterns; however, these findings should be interpreted as hypothesis-generating only, given the very small sample sizes per modality (n = 2-4) and the absence of a control condition. Conclusion: Overall, the results provide preliminary evidence that artistic-contemplative auditory interventions can modulate neural oscillatory dynamics, particularly within the high-frequency beta range. Given the small sample size, within-subject design, and lack of a control condition, these findings should be interpreted with caution and require confirmation in larger controlled studies.
