Control of an obscene "verbal tic" through timeout in an elementary school classroom

A classroom teacher modified the behavior of a 10-yr-old student who had a high rate of obscene vocalizations accompanied by facial twitches. In the first phase, the subject was instructed to repeat rapidly the most frequent obscene word in four daily 15-min sessions. This procedure reduced the frequency of obscene vocalizations, but not to an acceptable level. Subsequently, the teacher was able effectively to control the target behavior using a timeout procedure.
