When parents want to discourage nail biting and begin reinforcing writing as an alternative to anxiety, they use methods of differential reinforcement of alternative behaviors.
Differential Reinforcement of Alternative Actions (DRA): involves reinforcing behaviors that substitute for inappropriate behaviors. A good example of this is a child asking a parent for food. Every time a child makes a request, his parents ignore it.
Reinforcement can be used to teach new skills, teach alternative behaviors to disruptive behaviors, encourage appropriate behaviors, or improve task behaviors.
