This study examines two components of Azrin and Nunn's (1973) habit reversal procedure in an attempt to separate the effects of awareness training from the effects of competing response training. Research (Miltenberger, Fuqua, & McKinley, 1985) has indicated that an intervention combining awareness training and competing response practice is as effective as the entire habit reversal package in suppressing muscle tics. However, because the competing response component is always administered in conjunction with awareness training, the effects of each component are obscured. Four subjects, two with muscle tics and two with nervous habits, received an intervention of either awareness training alone or awareness training plus competing response training. Both interventions were effective in reducing or eliminating muscle tics and nervous habits, suggesting that a portion of the effect attributed to the competing response may be due to the awareness training component.
