The paper reviewed 5 experimental studies which focused on models' inhibitory and disinhibitory effects on sex-inappropriate behavior in young children. Studies revealed: 1) an exposure to the model displaying sex-inappropriate behavior has a disinhibitory effect on the observer, 2) it is unlikely that the observation of the female (male) model showing feminine (masculine) responses would facilitate the occurrence of similar behavior in observer boys (girls) when the status difference is clear between the model and observers, 3) the response consequence to the model's sex-inappropriate behavior is important in determining whether or not the observer reproduces the model's behavior or displays a similar class of responses, 4) the observer's control over the inappropriate responses may be acquired through the observation of the model inhibiting sex-inappropriate behavior, and 5) the presentation of the model who demonstrates alternative activities to sex-inappropriate responses can reduce the probability of occurrence of inappropriate behavior in the observer.
