The cost of using this technique as the treatment modality should be brought into consideration before the initiation of the therapy. It is also known as Intensive Behavioral Intervention. There are differences between these two kinds of therapy but most of the parents as well as layman usually consider both of these as a form of intense treatment plan which primarily includes careful observation and studying the patient usually the affected child and the treatment mainly applies the principles of Operant Conditioning which was1st presented in the theories presented by B. A study of the children affected by autism was carried out by Ivar Lovaas in 1980’ s and it was evident from the results of the study that main principles of ABA can be used in a program designed to treat the patients of autistic disorders.
This study showed marked improvement in the patients of autism if these techniques are used in a proper manner. There are many techniques which are currently the part of ABA management system and one of the principle techniques is Discrete Trial Teaching (DTT) which is used extensively nowadays.
The main aim of this technique is to maximize the learning process in the affected children and it is useful in the development of most of the skills e. cognitive, social, behavioral, fine motor, play as well as it can also be used to accelerate the ability of the children to help them at times. DTT usually involves the fragmentation of the main skill into several sub-skills and then each sub-skill is taught to the children intensely at a time. In actual practice, repeated sessions are planned with the child and involve prompting and then the prompt is faded to make sure the successful learning of that particular skill by the child.
It also uses the phenomenon of reinforcement to maintain the learned skills. One of the other principle techniques which are being employed in ABA is the use of the natural environment in the teaching of the child with autism and with the development of the child; more elaborated methods of teaching are incorporated in the training program to enhance the verbal and the social skills of the affected individual.
