fNIRS Dataset of Open Monitoring Meditation Modulating Negative Emotion Processing

This dataset focuses on the modulatory effect of open monitoring meditation on negative emotion processing and contains effect size data of task-related responses in prefrontal oxyhemoglobin concentration measured by functional near-infrared spectroscopy (fNIRS) while participants performed an emotional picture viewing task. The study employed a randomized pretest–training–posttest design and included 42 participants, who were assigned to either an open monitoring meditation group or a control group.

The meditation group received approximately 23 minutes of open monitoring meditation training, whereas the control group watched a neutral video. This dataset can be used for research on open monitoring meditation, negative emotion processing, and prefrontal functional activity.
