One in five people experience language-based learning disabilities, according to the National Center for Learning Disabilities. Dyslexia — difficulty reading or interpreting words, letters and symbols — is among the most common. A new study from the University of Missouri examined typically developing children and identified a clear connection between working memory and learning. Researchers say this insight could guide educators in tailoring instruction for children who struggle with language-based learning disorders.
“Working memory, or the retention of a small amount of information that is readily available, is an integral aspect to learning,” said Nelson Cowan, professor of psychological sciences in the MU College of Arts and Science. “Our goal was to understand the structure of working memory and how it relates to language use and intelligence in children.”
Working memory refers to the limited amount of information that a person can hold and manipulate in mind at one time. Cowan gives an everyday example: while listening to a story, a child must retain the opening sentence or paragraph long enough to connect it with what follows and make sense of the narrative. Cowan and colleagues suggest that weaknesses in this temporary storage — especially in the component that regulates attention — may underlie some language disorders, including dyslexia.
The research team tested 168 typically developing second-grade children, evaluating multiple aspects of working memory. They employed three theoretical memory models to explore how memory capacity, the focus of attention, and related processes interact with language skills and general intelligence. The battery of assessments challenged visual-spatial memory, phonological processing, and auditory working memory, giving a broad picture of each child’s abilities.

Study results indicated that a specific component of working memory, often described as the focus of attention, showed a strong correlation with both learning outcomes and measures of intelligence. In related prior work, Cowan demonstrated that attention control is central to how effectively working memory operates.
“Attention is vital to understanding phonetic sounds, reading words and solving mathematical problems,” Cowan said. Based on their findings, the authors suggest practical classroom approaches that could reduce cognitive load for struggling learners. For example, teachers can present smaller chunks of information, minimize multitasking demands, and emphasize one instructional target at a time so children can concentrate their attention where it matters most.
These instructional adjustments do not require new technology or extensive resources; they focus on sequencing, pacing and clarity. Strategies that align with the study’s implications include breaking reading or math tasks into brief, manageable steps; using clear verbal cues and visual supports to direct attention; and providing frequent opportunities for repetition and retrieval practice so information is consolidated from working memory into long-term memory.
While this study involved typically developing children rather than students already diagnosed with learning disabilities, the parallels suggest that strengthening attention and managing information flow could benefit those with language-based learning challenges as well. The research highlights that working memory is not an isolated trait but a process closely tied to how children process language and solve problems across subjects.

This research underscores the importance of attending to working memory and attention in early education. Practical classroom changes that reduce the amount of simultaneous information and focus student attention may improve comprehension and learning, especially for children who struggle with phonological processing and reading. Continued research and collaboration between cognitive scientists and educators can refine these approaches and test their impact in diverse classroom settings.
