Here are some definitions of some of the key terms used in ABA support

Autism Spectrum Disorder (ASD): Autism Spectrum Disorder (ASD), also called ‘Autism’, is a lifelong neurodevelopmental disorder that affects how people communicate and relate to others. The range and intensity of disability varies, but all people affected by ASD have difficulty with communication, social interaction, and restricted or repetitive interests and actions. Many have difficulty responding appropriately to their environment.


Applied Behaviour Analysis (ABA): The science in which tactics derived from the principles of behaviour are applied to improve socially significant behaviour and experimentation is used to identify the variables responsible for the improvement in behaviour.

Intensive Behaviour Intervention (IBI): The application of ABA principles in an intensive setting, in order to result in behaviour change and improvement.

Learning Disability (LD): “Learning Disabilities” refers to a variety of disorders that affect the acquisition, retention, understanding, organization or use of verbal and/or non-verbal information. Learning disabilities may also cause difficulties with organizational skills, social perception and social interaction. Learning disabilities are due to genetic, other congenital and/or acquired neuro-biological factors.

Verbal Behaviour: Behaviour whose reinforcement is mediated by a listener; includes both vocal-verbal behaviour and non vocal-verbal behaviour. Encompasses language and topics such as thinking, grammar, composition, and understanding.
