ABSTRACT:
A method for using patient feedback to influence presentation of sound stimuli during music therapy comprises presenting a first stimulus to induce a predicted degree of expectancy fulfillment, detecting brain electrical activity generated by the patient in response thereto, determining values of certain parameters of the brain electrical activity, comparing the parameters to a classification library to determine the actual degree of expectancy fulfillment or violation, calculating a correction factor based on the difference between the predicted and actual degrees of expectancy fulfillment or violation, determining the configuration of a second stimulus taking into account the correction factor, and arranging and presenting the second stimulus to the patient. Apparatus for carrying out the method comprises an arrangement of readily available hardware and software components.
