Key findings
Phonological awareness was the single strongest predictor of every reading skill evaluated. Together, the cognitive predictors accounted for 55% of the variance in decoding performance. Furthermore, verbal working memory uniquely predicted reading fluency and comprehension, while parent-rated attention problems specifically predicted reading fluency, with the model explaining 46% of the overall variance in fluency.
Methodology
The researchers evaluated a community sample of 182 children, ages 8–12 years, including individuals with ADHD, reading disorders, both conditions, or typical development. They measured phonological processing (phonological awareness, rapid naming, and phonological memory), verbal working memory, and parent-reported attention problems. These cognitive measures were used to predict children's performance across key reading dimensions including decoding, word recognition, reading fluency, and comprehension.
Limitations
Because this study used a correlational design and tested participants at only a single time point, it cannot prove that cognitive deficits cause reading difficulties. The reading fluency and comprehension tasks relied on short sentences and passages, meaning the results might not generalize to how attention or working memory impacts the reading of longer, more complex texts. Additionally, attention control was assessed using parent questionnaires rather than direct, experimental measures of sustained attention.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
Working memory capacity is a significant predictor of academic outcomes, specifically in mathematics and reading.
Evidence for the claim as stated.
Phonological awareness is a powerful predictor of multiple reading skills including decoding and word recognition, but reading fluency and comprehension are also uniquely predicted by other cognitive variables such as working memory and attention.
Evidence for the claim as stated.
While phonological awareness is the dominant predictor of academic and reading outcomes in typically developing children, evidence suggests it may not be the primary predictor of academic success in clinical groups, such as bilingual children with developmental language disorder, where rapid naming skills can be more predictive.
Evidence for the claim as stated.
While phonological processing skills are strong predictors of overall reading performance, domain-general cognitive factors like working memory and attention control uniquely contribute to reading fluency and comprehension.
Evidence for the claim as stated.
Linguistic and reading difficulties are multifactorial, involving not only phonological processing deficits but also general attention control, decision-making parameters, and visual sensory processing speeds.
Evidence for the claim as stated.
While some evidence suggests that phonological awareness is the dominant cognitive predictor of reading and academic performance across general and typical student populations, longitudinal data from atypical populations (such as bilingual children with developmental language disorders) indicates that rapid naming skills can emerge as the unique predictor of long-term academic success instead.
Evidence for the claim as stated.
