Model law (modeling). He believes that many children's behaviors are not formed through direct practice or reinforcement, but through observation and learning, thus increasing the acquisition of good behaviors or reducing and weakening bad behaviors. So imitation is a basic form of learning, just like reinforcement. Model laws include on-site demonstration, participatory imitation, self-demonstration, film, television or video demonstration and imaginative imitation. The demonstration method has the advantages of quick effect and wide application range. It can also be combined with other behavioral therapy methods, which is especially suitable for group psychotherapy. Lovaas 1977 reports that the combination of demonstration and reinforcement is used to promote the language and behavior development of autistic children.

operational approach

1. Live demonstration, so that sick children can watch how other children play and get along with dogs in the real environment. It is reported that the effective rate of this method is 50% ~ 67%.

2. Participate in the imitation method to let the sick child observe and demonstrate that the child plays with the dog, and let him gradually participate in such activities under the guidance. The effective rate is as high as 80% ~ 92%.

3. Movie, TV or video demonstration method allows sick children to watch movies, TV or videos where the presenter gets along with the dog, so that they can gradually imitate the behavior of the presenter and eliminate their fear of dogs. The effective rate is 20% ~ 30%. When using the model law, the target behavior should be determined according to the ability of sick children. During the demonstration, if the sick child can concentrate, he can increase the presentation time of the demonstration behavior and let him have more time to watch the demonstration.
