Children with Autism may have difficulty demonstrating a needed response in environments and situations not included when learning that response. When this is the case, generalization is the skill lacking here. This can present itself in many ways such as across people, materials used, physical locations and ways in which opportunities to respond are stated (for example a request stated differently). Part of any successful ABA program is to address any difficulties with generalization for an individual and to ensure that as they progresses through a program they are able to develop a generalized response. It is when this is addressed that our children actually master skills and become more ready to be independent learners!
