Communication in children on the autism spectrum
Under DSM-5, autism is diagnosed by behaviour in two domains — difficulty in social communication and interaction, and repetitive behaviours with restricted interests; language itself varies widely between children, so a rich vocabulary does not rule autism out.
Why it matters in the exam
Exam questions test the criteria: a lack of gestures and non-verbal communication is part of the social criterion; Asperger syndrome was considered a separate disorder only until DSM-5; and the diagnosis is behavioural, not genetic. A common case: a 5-year-old referred for an /s/ error who, during therapy, turns out to quote sentences from television and talk a lot about one topic — autism spectrum should be suspected.
Another part concerns communication and treatment: echolalia, such as repeating "do you want a cookie?" when the child wants a cookie, is often a communicative attempt and should be treated as a request; initiating joint attention is the most consistent predictor of later language; AAC does not stop speech and may even help it; the DIR approach focuses on sensory regulation and emotional integration; and social (pragmatic) communication disorder is diagnosed when there are pragmatic difficulties without repetitive behaviours. Atypical intonation should raise suspicion of hearing loss or autism.
Key points
- DSM-5: social communication and repetitive behaviours; a behavioural diagnosis.
- Language varies; good language does not rule out autism.
- Echolalia can be communicative.
- Initiating joint attention predicts language; AAC does not stop speech.
- Social-pragmatic disorder: pragmatic difficulties without repetitive behaviours.
Summary table
| Topic | What is true | For the exam |
|---|---|---|
| Criteria (DSM-5) | Difficulty in social communication (reciprocity, non-verbal communication, relationships) and repetitive behaviours with restricted interests | A behavioural diagnosis; Asperger syndrome merged into the spectrum |
| Language | Varied: from children with almost no speech to a rich vocabulary and complex sentences | Good vocabulary does not rule out autism; prosody is often atypical |
| Echolalia | Immediate or delayed repetition of heard sentences | Often a communicative attempt — respond to the intent |
| Language predictor | Initiating joint attention | The most consistent predictor in a minimally verbal child |
| AAC | Does not stop speech and may promote it | Do not postpone it because of parents' fears |
| Treatment approaches | Behavioural (ABA), naturalistic developmental, DIR (sensory and emotional regulation) | Social-pragmatic disorder: without repetitive behaviours |
| Sex differences | A different expression of the same condition in girls | Girls are sometimes diagnosed later |
