Chapter 19 / Module 18 – Autism Spectrum Disorder (ASD) & Behavioural Learning

 

What is Autism Spectrum Disorder (ASD)?

Autism Spectrum Disorder is a neurodevelopmental condition that affects:

  • Social communication
  • Interaction with others
  • Behaviour and sensory processing

It is called a spectrum because it affects people in different ways and different levels of support are needed.

Key features include:

  • Difficulty with social communication
  • Challenges with non-verbal communication (facial expression, eye contact)
  • Differences in understanding social situations
  • Repetitive behaviours or routines
  • Sensory sensitivities

Some people may be non-speaking or use alternative communication methods.


Early Signs of Autism (12–24 months)

Early indicators may include:

  • Limited eye contact
  • Delayed speech or language development
  • Reduced response to name
  • Less interest in social interaction
  • Repetitive movements or play patterns

Early support can make a significant difference in development.


Core Areas Affected in Autism

1. Social Communication

  • Difficulty understanding tone of voice
  • Challenges with conversation back-and-forth
  • Difficulty understanding social rules

2. Behaviour

  • Repetitive movements or routines
  • Preference for sameness
  • Distress with change

3. Sensory Processing

  • Over- or under-sensitivity to:
    • Sound
    • Light
    • Touch
    • Smell

Key Autism-Related Terms

  • Echolalia – repeating words or phrases heard
  • Functional communication – expressing needs and feelings effectively
  • Theory of mind – understanding that others think and feel differently
  • Repetitive behaviours – repeated actions or routines for comfort or regulation

Applied Behaviour Analysis (ABA)

ABA is a structured therapy approach used to support people with autism.

It focuses on:

  • Teaching new skills
  • Reducing behaviours that cause difficulty
  • Reinforcing positive behaviours

ABA is often used in educational and clinical settings and may be covered through specialist programmes.


Generalisation and Maintenance (Learning Skills)

These are important parts of autism support and behavioural learning:

Generalisation

This means using a learned skill in different situations, such as:

  • With different people
  • In different places (home, school, community)
  • With different materials or tasks

Example:
A child learns to ask for water at home → then uses the same skill at school.

Maintenance

This means:

  • Keeping a skill over time
  • Not forgetting what has been learned

Both are essential for real-life independence.


Strategies to Support Learning

To help skills generalise and last:

  • Involve family and carers in learning
  • Practice skills in real-life environments
  • Repeat learning over time
  • Use consistent routines
  • Adapt environments when needed

TRICARE Autism Care Demonstration (ACD)

This programme supports eligible individuals with autism by funding services such as ABA therapy.

Key features:

  • Requires a formal ASD diagnosis
  • Uses structured assessments (e.g., ADOS-2, CARS-2)
  • Provides access to trained behaviour specialists
  • Assigns an Autism Services Navigator (care coordinator)

It is designed to support structured behavioural and developmental care.


Support Roles in Autism Care

  • Behaviour technicians (direct support)
  • Behaviour analysts (programme design and supervision)
  • Care coordinators / navigators
  • Family members and educators

Key Takeaway

Autism is not an illness.

It is a lifelong neurodevelopmental difference that affects:

  • Communication
  • Social interaction
  • Behaviour and sensory processing

With the right support:

  • Skills can be learned
  • Independence can increase
  • Quality of life can improve
