Cognitive and linguistic predictors of reading comprehension in children with intellectual disabilities.
Kids with ID can sound like good readers yet still miss the point—teach them to answer 'why' questions, not just 'what' questions.
01Research in Context
What this study did
van Wingerden et al. (2014) tested how well kids with intellectual disabilities understand what they read. They compared two groups: kids with ID and kids without. All could read the words out loud. The team asked both explicit questions (what the text said) and implicit questions (what the text meant).
They also checked each child's language skills. They wanted to see if language skill predicted reading scores.
What they found
Both groups answered the easy, direct questions about the same. When the questions required reading between the lines, the ID group scored much lower. Language skill helped only with the direct questions, not the deeper ones.
In short, decoding is not enough. Kids with ID can read the words but still miss the point.
How this fits with other research
Wormald et al. (2019) tracked reading speed in grades two through eight. They found that speed, not accuracy, falls further behind each year. Evelien's work shows the same kids also struggle with hidden meaning. Together, the papers say: watch both speed and inference as kids age.
Manor-Binyamini et al. (2021) studied kids with 22q11.2 deletion syndrome. Like Evelien's ID group, these kids understood stories worse than their mental-age peers. Both studies warn against trusting IQ or decoding scores alone.
Chandler et al. (1992) taught idioms to kids with ID and saw gains. Evelien did not test teaching, but both papers show that higher-order language can be trained. Use K's story-plus-picture method to practice 'why' questions after reading.
Why it matters
If you work with school-age kids who have ID, do not stop at fluency drills. After each short passage, ask one 'why' or 'how do you know' question. Model the answer, then fade prompts. Track correct inferences, not just words read per minute.

03Original abstract
A considerable number of children with intellectual disabilities (ID) are able to acquire basic word reading skills. However, not much is known about their achievements in more advanced reading comprehension skills. In the present study, a group of 49 children with ID and a control group of 21 typically developing children with word decoding skills in the normal ranges of first grade were compared in lower level (explicit meaning) and higher level (implicit meaning) reading comprehension abilities. Moreover, in the group of children with ID it was examined to what extent their levels of lower level and higher level reading comprehension could be predicted from their linguistic skills (word decoding, vocabulary, language comprehension) and cognitive skill (nonverbal reasoning). It was found that children with ID were weaker than typically developing children in higher level reading comprehension but not in lower level reading comprehension. Children with ID also performed below the control group on nonverbal reasoning and language comprehension. After controlling for nonverbal reasoning, linguistic skills predicted lower level reading comprehension but not higher level reading comprehension. It can be concluded that children with ID who have basic decoding skill do reasonably well on lower level reading comprehension but continue to have problems with higher level reading comprehension.
