Abstract: A method for treating emotional and behavioural disorder includes using a sensor to obtain data pertaining to physiological responses of a user to an emotionally loaded sentence, to listed emotions, to listed chronological periods in the user's life, and to listed causes that may have led to absorption of an emotion during a period in the user's life. From the physiological response, an emotion having greatest emotional effect on the user, when it was absorbed, and its cause are determined. The user is presented with information associating the emotion, chronological period and cause. A sensor is used to obtain physiological data pertaining to the response of the user to a second instance of exposure to the emotionally loaded sentence. A result of treatment is determined by analysing and comparing the physiological data pertaining to the first and second exposures of the user to the emotionally loaded sentence.
