The Applied Behavioural Analyses, Intervention in Autism: Psychologists' Perspective

Applied Behaviour Analysis (ABA) is a behavioural intervention model primarily based on instrumental conditioning, which follows the principle that behaviour is a function of its consequences. It is commonly used with children who have diverse abilities, such as those with autism spectrum disorder, intellectual disabilities, and similar conditions. ABA is an evidence-based and effective approach for managing behaviours associated with autism.

The ABA approach focuses on using rewards or reinforcements to encourage desirable behaviours and reducing problem behaviours by applying positive consequences or consequences such as “time-out,” “extinction,” or withholding privileges following undesirable behaviours. This method was first introduced by American psychologist Ivar Lovaas in 1987 to improve social interaction and reduce maladaptive behaviours in children with autism.
