Verbal working memory and reading abilities among students with visual impairment.

Argyropoulos et al. (2017) tested how verbal working memory links to reading in students with visual impairment. They gave memory and reading tasks to a group of these students. The team then looked at which reading skills matched memory scores.

Strong verbal working memory went hand in hand with better decoding and comprehension. The same memory scores did not predict reading fluency. In short, memory helps students figure out words and understand text, but not read them faster.

The result lines up with Symons et al. (2005) and Cullinan et al. (2001). Both found that phonological memory, a close cousin of verbal working memory, predicts word reading in Down syndrome and in broader intellectual disability. It also echoes Peeters et al. (2009): children with cerebral palsy who have weaker speech and lower IQ tend to score low on verbal working memory tasks. Together these papers show that across several disabilities, verbal memory is a core reading skill.

A slight twist appears with Levy (2011). That study found IQ, not memory, carried the weight once statistics were run. The difference is age and sample: Yonata tested older teens with intellectual disability, while Vassilios looked at school-age students with visual impairment only. When IQ range is wide and teens are involved, IQ can mask the memory effect. In the visual-impairment group, memory still shines through.

If you teach learners who are blind or have low vision, check verbal working memory early. A quick memory span task can flag who will struggle with decoding and comprehension. Pair these students with extra phonics practice and meaningful text, not just speed drills, since fluency is not driven by memory. Re-screen each year; as vocabulary grows, memory may improve and lift reading with it.
