New research led by Texas A&M University suggests that reading success depends less on general intelligence or visual processing than commonly assumed. Instead, auditory processing—the ability to recognize speech sounds—and comprehension knowledge, including vocabulary and background information, were the strongest predictors of reading comprehension in a large analysis of children’s cognitive and achievement measures.
Study examines the abilities linked to reading success
For decades, explanations for why some children struggle with reading have often focused on intelligence and visual information processing. Children who read easily may be viewed as more intelligent, while those who have difficulty reading may be considered less capable. Reading comprehension problems are also frequently attributed to difficulty interpreting words and letters on the page.
Dr. Daniel Hajowski, an associate professor in the Department of Educational Psychology at Texas A&M University, led one of the most extensive studies to date examining how cognitive abilities relate to reading comprehension. Researchers from the University of Kansas, St. John’s University, Montclair State University and Temple University also contributed to the work.
The researchers combined 50,000 correlations from a battery of 137 cognitive and achievement tests into a single statistical model. This large-scale approach allowed them to examine how different mental abilities relate to reading comprehension and may help explain why earlier studies have sometimes produced conflicting results.
Visual processing showed no significant relationship with reading comprehension across the analyses. General intelligence was associated with reading comprehension, but the relationship was considerably smaller than some previous studies had suggested.
Instead, auditory processing and comprehension knowledge emerged as particularly important predictors of reading success.
“One notable finding was that general intelligence was less dominant than in some previous meta-analyses,” Hajowski said. “Broad abilities such as comprehension knowledge and auditory processing played a strong and specific role in reading beyond general intelligence, especially in decoding and comprehension.”
Auditory processing and comprehension knowledge
Auditory processing involves recognizing and distinguishing the individual sounds in spoken words. Children need to identify these sounds to understand how they correspond to written letters, a skill that supports decoding—the process of working out how written words are pronounced.
Comprehension knowledge includes the vocabulary, concepts and background information children build through education and everyday experiences. This foundation can make it easier to understand the meaning of individual words, sentences and longer passages.
Together, auditory processing and comprehension knowledge showed a stronger relationship with reading comprehension than any other abilities examined in the study. Memory, reasoning and mental processing speed also contributed to reading development, but played more supportive roles.
The findings suggest that reading is not simply a reflection of general intelligence or visual processing ability. Language-related skills appear to play a particularly important role, supported by several interrelated cognitive abilities.
What the findings could mean for children with reading difficulties
The research may help educators better understand why individual students struggle with reading. Instead of treating all reading comprehension problems as identical, teachers may be able to identify specific weaknesses and provide instruction designed to address them.
The findings also offer an encouraging message for families. Children who struggle with reading are not necessarily less intelligent or incapable of becoming strong readers. Their difficulties may reflect particular abilities that need additional development and support.
“Reinforcing basic skills at home, even those that seem simple, can have a meaningful effect on higher-level reading skills,” Hajowski said. “Lower reading comprehension is not a sign of poor ability, but often reflects specific skills that need to be strengthened within a larger system that works together.”
The finding highlights the value of helping children build essential reading skills through consistent support at school and at home. Hajowski said the most effective approach involves collaboration among schools, parents and the wider community.
Reading develops through a network of connected skills, and strengthening that foundation step by step can help children become more confident and competent readers.
