This study investigated the efficacy of negative feedback, over correction, and short periods of negative practice in the treatment of tics. Three Ss with different types of tics were treated. The first S was given negative feedback contingent upon the emission of a lip tic. The result was a marked reduction in the frequency of his tics during the treatment phase. The second S was given negative feedback and was required to overcorrect her leg tic by walking a long corridor without emitting the tic. Here, too, there was a marked reduction in the frequency of her tics. The third S was treated using negative feedback and short periods of negative practice. The negative feedback resulted in an increase in the frequency of his tic--an unexpected effect. The S's head tic was finally reduced to a low frequency when negative practice was made contingent to the emission of head tics while the S was under observation. The results tended to support the efficacy of negative feedback in the treatment of tics with some Ss.
