Inferential ability in children with cerebral palsy, spina bifida and pragmatic language impairment.

Holck et al. (2010) watched how kids answered inference questions during short stories. They compared three groups: children with pragmatic language impairment, cerebral palsy, and spina bifida.

The team coded each wrong answer. They asked, 'Did the child miss the clue in the story, or lack real-world knowledge?' This split helps you see why the child struggles.

Kids with pragmatic language impairment made more inference errors than the other two groups. Their mistakes usually came from missing social cues in the text, not from lacking facts.

Children with cerebral palsy or spina bifida often knew the facts but needed extra help linking them. The coding scheme cleanly separated these two error types.

Freed et al. (2015) later showed that spoken story-level scores predict reading success in the same PLI group. Together, the papers tell you to probe both oral inference and print inference.

Cheng et al. (2024) systematic review flags inference questions as extra hard for kids with developmental language disorder. Pernille’s fine-grained coding shows one reason why: social-cue blindness, not world knowledge.

Sullivan et al. (2020) found that kids with visual impairment struggle only with spatial inferences. The 2010 study adds that PLI kids struggle with social inferences. Method looks similar, deficit is domain-specific in both.

Next time a child bombs an inference question, don’t just mark it wrong. Ask yourself: did they miss the social clue or lack the fact? If it’s a social-cue miss, add perspective-taking drills. If it’s a knowledge gap, pre-teach vocabulary and background facts. This quick split guides your intervention target within the same session.
