Early intensive behavioural intervention (EIBI) programmes have been proven to be effective at teaching children with autism spectrum disorder (ASD). An examination of components of these programmes is made, focusing on methods of discrete trial teaching (DTT) and discrimination training. The importance of stimulus control in EIBI programmes is explored, specifically in teaching intraverbal behaviour. It is argued that antecedent stimuli in intraverbal behaviour are complex, and can include compound stimuli, as well as making conditional discriminations. Further, it is shown that teaching listener behaviour can help with the emergence of intraverbal behaviour for children with ASD. Long-term benefits of EIBI programmes are shown in an outcome follow-up study that measured the progress made by children with ASD at an average age of 15 years.
