Pat exhibits disruptive behaviors like tantrums, hitting and screaming during discrete trial training sessions. There are three potential reasons for these behaviors: the tasks may be too difficult, the tutor does not provide strong enough reinforcers, or the tutor provides attention after disruptive behaviors. To address this, the tutor should make tasks easier, use stronger reinforcers like playing, and limit attention after disruptive behaviors. Playing is especially important as a reinforcer for children with functional skills.
