different settings and people without prompt dependence. The study completed by McGee and Daly (2007) showed that the social phrases learned in their study by the three autistic boys were transferred across different periods and situations without prompts. According to McGee et al. (1999) the strong interest and favor to incidental teaching was due to the need to overcome the generalization issue that occurred in other behavioral interventions.

As mentioned earlier, incidental teaching is a procedure is reinforcing because the child initiates the intervention based on their own interest, and receives the reinforce when the child attempts to follow the instructor’s prompt. Incidental teaching is also an intervention that promotes lasting and impactful results because it is an intervention that is early, it also can be done in a variety of settings with different people, it can have family involvement, the procedure can include peers, and it is fun for the child since it initiated by the child (McGee et al., 1999). Since it is child selected, it drives the child’s motivation, which ultimately assists the child to learn.

Limitations

Incidental teaching is a procedure that has shown a lot of progress in children, especially in vocalization. However, the teaching procedure is mainly an intervention that focuses on verbal communication and can be limiting to certain children with ASD, especially those who are severe. McGee et al. (1983) modified the standard incidental teaching for autistic children with severe language deficits shown evident progress in the subjects. However, the setting was more contrived and it was not based on the interests of the child. In addition, many studies mentioned that it is beneficial for the child to initiate, but it becomes challenging to use incidental teaching past a certain age because then the interests start to become narrower and more depleted.

It is also difficult to find a “perfect” intervention for ASD because it i
