Abstract
Self-monitoring technique was used for eliminating tics and obsessive behavior together with negative practice. The treatment processes of four patients were reported ; there were three primary school boys and one adult lady. These behavior problems were an obsession of stepping a cover of a manhole on the road, a head shaking, voicing "kun, kun" in the class room and a head shaking from left to right of the lady which had been continued for a period of about ten years. Behavior modifications of these tics and an obsessive behavior had been continued till decreasing about 0. The effective of the self-monitoring technique was not cleary concluded because of using with other methods ; negative practice, autogenic training or medication. As Thoresen and Mahoney (1974) had suggested before, it is essential to use together with other methods in order that self-monitoring is utilized effectively. Nevertheless, the author postulated from the treatment of the four cases that the large function of self-monitoring is "awareness" for abnormal behaviors and leads extinction because the response loop of these behaviors will be able to be broken down.
