What Is ABA?

Applied Behaviour Analysis (ABA) is the science of understanding how behaviour works, how people learn and how the environment influences what we do.

ABA is not a therapy designed exclusively for autistic children. It is a well-established scientific discipline with applications across all ages and many areas of life, including education, healthcare, mental health, sports, workplace performance and everyday behaviour change.

ABA has its roots in behavioural research from the early twentieth century. Since the 1960s, its principles have been increasingly applied to support people with autism and other developmental or learning difficulties.

Today, ABA includes a wide range of teaching approaches, from structured learning activities to naturalistic, play-based interventions.

What Does Research Tell Us?

ABA is one of the most extensively researched approaches used in autism intervention. Research has shown that specific ABA-based strategies can help develop communication, social interaction, learning and daily living skills.

Every individual learns differently, so intervention must be adapted to their strengths, needs and priorities. Progress is regularly measured, and teaching strategies are adjusted based on what works.

The aim is to develop meaningful skills, increase independence and improve quality of life.

Teaching Approaches and Programmes

ABA is a science, not a single therapy or teaching method. It provides the principles behind a variety of evidence-based teaching strategies and intervention programmes.

These include:

• Discrete Trial Teaching (DTT): Teaching new skills through structured, step-by-step learning.

• Natural Environment Teaching (NET): Using play, daily routines and naturally occurring opportunities to support learning.

• Verbal Behaviour (VB): Developing functional communication and language skills.

• Functional Communication Training (FCT): Helping individuals communicate their needs effectively, including as an alternative to challenging behaviour.

• Early Start Denver Model (ESDM): Combining developmental and behavioural strategies in play-based early intervention.

• JASPER (Joint Attention, Symbolic Play, Engagement and Regulation): A naturalistic, developmental and behavioural approach focusing on shared attention, play, social communication and engagement.

These approaches are not interchangeable or suitable for everyone. They are selected according to the individual's developmental level, learning needs and goals.
