Behavioural rigidity is one of the characteristics of a child with ASD. When it comes to teaching a program or concept, the responses may be very simplistic at first e.g. ‘What’s your name?’ ‘John’. ABA then overcomes this rigidity by using many different examples to build on this response and transfer it to naturalistic settings. E.g. having someone else to ask ‘What’s your name?’ Or use a different way of asking ‘Your name is_____.’, ‘How would you like to be called?’. We also emphasis children's ability in expressing their desires and preferences through communication and let their personality shine through.
