The two types of intervention methods which are seen in different research methods definitely include the Applied Behavioural Analysis. The ABA is a way in which the positive behaviors are reinforced by providing some stimulus after the child actually does that kind of behavior. The Positive stimulus can be an appreciation of a pat or anything. The basis of positive behavior should be the desire of the child. In this way gradually the positives of the child are reinforced and the symptomatic behaviors are eliminated.
