A method and system for instructing a user behavior change comprising: collecting a first and a second bioelectrical signal dataset； generating an analysis based upon the first and the second bioelectrical signal datasets； and providing a behavior change suggestion to the user based upon the analysis. The method can further comprise collecting a third bioelectrical signal dataset associated with a performance of an action by the user in response to the behavior change suggestion； generating an adherence metric based upon the third bioelectrical signal dataset and at least one of the first and the second bioelectrical signal datasets； providing a stimulus configured to prompt an action by the user； and providing at least one of the analysis and an analysis based upon the adherence metric to the user. An embodiment of the system comprises a biosignal detector and a processor configured to implement an embodiment of the method.
