Understanding Your Child's Brain
My child can read fluently. So they must understand. They just don't want to answer.
Hyperlexia (advanced decoding) doesn't guarantee comprehension. Reading words and understanding meaning are different processes.
Hyperlexia (fluent reading decoding that outpaces comprehension) and reading comprehension deficits are dissociable in autism.
**Decoding vs. Comprehension:** Reading fluency — sounding out words correctly — is different from reading comprehension — understanding what the words mean.
Many autistic children excel at decoding. They recognize letter patterns, sound out words, read fluently and with good pronunciation.
But comprehension lags. They don't automatically understand what they read, despite perfect decoding.
**Why This Happens:** Decoding is about pattern recognition and phonological processing. Autistic children often excel at pattern recognition.
Comprehension requires: - Understanding vocabulary in context - Making inferences (reading between the lines) - Understanding cause and effect - Holding the whole story in working memory - Integrating prior knowledge
These are different cognitive processes, and they can develop at different rates.
**Language Comprehension Challenges:** Many autistic children have difficulty with: - Abstract language ("the sky fell" = the child is sad, not literal sky) - Figurative language (idioms, metaphors, sarcasm) - Implied meaning (what someone said vs. what they meant) - Discourse comprehension (understanding how sentences relate to each other)
**Working Memory Load:** Comprehension requires holding information in working memory. A child with strong decoding but limited working memory can read the words but forget what earlier sentences said before reaching the comprehension question.
**How to Support:** - Ask factual questions (answers are directly in the text) before inferential questions - Reduce the complexity of the reading material - Use visual supports alongside text - Help your child understand vocabulary before reading - Ask one question at a time, not multiple questions
Don't assume fluent reading means full comprehension. Ask comprehension questions to verify understanding.
Teach comprehension skills explicitly. Ask factual questions first ("What color was the cat?") before inferential questions ("Why did the cat go outside?").
Use visual supports. Pictures alongside text help comprehension. Read together and discuss.
❌ Assign reading without checking comprehension. Your child may read fluently while understanding very little.
❌ Ask complex inferential questions without building understanding first.
❌ Assume lazy reading. The child is reading; they just don't understand the implied meanings.
