Communication
Communication is the exchange of information between two or more people through a common system of symbols, signs, or behaviours. It is more complex than language alone as it is affected by social and cultural influences, which are often subtle and complex.
When we think of communication, the first thing that springs to mind is usually verbal communication, which refers to speaking and understanding language, either with or without aids for support. Communication also includes non-verbal communication, which refers to elements such as gesture (including signing), facial expression (including eye contact), and body language that help us communicate our message, and understand the messages that others are sending to us. Some children with ASD find it hard to interpret non-verbal communication in others. For example, they might not respond to a teacher waving them over to join in a game with the rest of the class. They might also find it difficult to use non-verbal signals to enhance their own communication. For example, they might turn their back to a peer who is talking to them.
To be an effective communicator we must use a combination of expressive language, receptive language, and pragmatic language.
Expressive and Receptive Communication
The following list represents typical communication development. Your child may benefit from speech therapy if they are having difficulty performing these skills:
By the age of 1 year, children are expected to:
- copy facial expressions with caregivers, such as smiling when a parent smiles
- follow your eye gaze to an item of interest
- respond to people talking to them (e.g. by turning to them)
- understand their name and respond to it
- understand words such as 'no'
- identify some common objects and known people (e.g. 'where’s Daddy?')
- understand simple instructions accompanied by gesture (e.g. putting your hand out and saying “give it to me”)
- use gestures (e.g. waving, shrugging, pointing) and facial expression to communicate
- start to use 2-3 words besides ‘mama’ and ‘dada’, try to copy words and sounds after you say them.
By the age of 2 years children are expected to:
- pull you to objects of interest (e.g. pulling a caregiver to a toy they can’t reach)
- be able to understand a wide range of words
- understand and respond to simple yes/no questions and one step instructions (eg. "push the car")
- use a range of words, some of which may only be recognisable to familiar people
- use 2-3 words together
- ask basic questions (eg. "what’s that?")
- use some action words (eg. "go") and describing words (eg. "big")
By the age of 3 years children are expected to:
- understand some concepts and describing words (e.g. cold/hot)
- follow 2- and 3-step instructions (e.g. "get your cup and put it on the table")
- categorise items (e.g. by different colours or sizes)
- understand not (e.g. "we are not going swimming today")
- use sentences of 3-4 words or more
- ask what and where questions
- use words such as you and me (e.g. "will you play with me?")
- have simple conversations and tell simple stories
By the age of 4 years children are expected to:
- put together sentences of 4-5 words in the correct order
- speech should be intelligible with few error sounds
- ask who, what, where, when, and why questions
- describe past experiences and tell stories
By the age of 5 years children are expected to:
- follow instructions with a series of steps
- use an extensive range of words and produce complex sentences with correct grammar most of the time
- use and understand location words (e.g. near, under, on)
- use reasoning and problem-solving skills to answer how and why questions
- yell stories and talk about the present, past, and future
By the age of 6 years children are expected to:
- understand and talk about concepts such as similarities and differences
- communicate effectively in classroom and social situations
- understand group instructions
- understand conversations between peers
- understand and use more complex grammar
Important Note:
These examples are based on typical developmental milestones, but it is important to remember that all children will develop in different ways and at different speeds. Please use this information as a guide only, and always discuss your concerns with a qualified professional who will help guide you in finding the best support for your child.
If you feel your child may benefit from assistance with the development of language skills, please contact a speech pathologist for further support and advice.

Pragmatic Communication
Many children with ASD find the social aspect of language difficult to understand and hard to learn. Pragmatic language refers to the social communication and language skills we use in our day to day interactions. It includes what we say, how we say it (both verbally and non-verbally) and how appropriate it is to the given situation.
Understanding pragmatic language involves looking at both verbal and non-verbal ways that people communicate their messages. Non-verbal pragmatic communication can include the understanding and use of eye contact, body language, facial expression and tone of voice. Verbal pragmatic communication might include the ability to express our wants and needs, thoughts and ideas, and our feelings.
Good pragmatic language is critical for successful social interaction. Children who have difficulty with verbal and non-verbal pragmatic skills also have difficulty recognising and understanding other people's communication which often leads to confusion for the child.
Because pragmatic communication can be difficult for children with Autism Spectrum disorder, they often have trouble following the rules of conversations such as turn-taking, staying on topic and showing interest in other people's conversations.
The following list will help you to identify some areas of pragmatic difficulty your child may be experiencing. You might want to consult a speech pathologist if your child is not using gesture, vocalisations, behaviour or words to:
- look at you when they want something
- reach or point to something that they want
- reject or protest when they don't want something
- greet people and/or communicate 'bye bye'
- indicate they need help
- show you things they are interested in (e.g. by bringing to you or pointing)
- approach you to engage in social games such as peek-a-boo or tickling games
- let you know they need comfort
- tell you what they want you to do (e.g. "give ball", "push swing")
- draw your attention to something they want you to notice (e.g. "look plane")
- ask questions, especially what, who and where questions
- make comments (e.g. "yukky", or "it's hot")
- request permission (e.g. "can I have...?")
- express feelings and opinions
- talk about a variety of topics
- take turns in conversation
If you feel your child may benefit from assistance with the development of pragmatic language skills, please contact a speech pathologist for further support and advice.
