A system for facilitating a subject's functional development includes sensing devices configured for sensing mind state signals； sensing devices configured for sensing body state signals； and a set of processing resources configured for generating a mind state indicator/measure, a body state indicator/measure, and a mind-body synergy indicator/measure that corresponds to which each of the subject's mind state and body state are synergistically aligned for facilitating the subject's functional development. The system can be configured for concurrently presenting a set of activities involving a model body part； engaging in attempted imitation of the set of activities by way of attempted movement of a body part that is a mirror image of the model body part； presenting an indication of an extent to which each of the mind state and body state are cooperative with respect to performance of the set of activities； and presenting an indication of relaxation.
