• Participation in EEG-related research or formal EEG training within the past 12 months.
• Inability to access or utilize required technology (e.g., computer or tablet with internet access) necessary for completion of digital modules and online assessments.
• Any condition (physical, psychological, or cognitive) that, in the opinion of the site investigator, would preclude full participation in study activities or completion of the study protocol.
