This dataset contains MEG recordings from participants performing a risky decision-making task alongside a localizer task and a probability learning task. It was collected to investigate heuristics in risky decision-making and their relationship to preferential neural representation of choice- and outcome-related information. The dataset includes raw MEG data and derivative event and epoched data tables supporting analyses reported in an associated preprint.

This multimodal neuroimaging dataset investigates the neural mechanisms of metacognition—the ability to assess decision confidence—by isolating postdecisional from decisional contributions. Healthy volunteers performed perceptual judgments and observed decisions while reporting confidence, with concurrent electroencephalography and functional magnetic resonance imaging recordings. The study reveals dissociable neural correlates of confidence in prefrontal regions and proposes a computational model explaining how decision commitment enhances metacognitive performance.
