Stanford researchers identify that developmental dyscalculia may be linked to challenges in attention, memory, and strategy switching, offering new insights for tailored interventions.
Children who struggle persistently with maths may not simply be behind on practice; their difficulty may also lie in the way they choose and change strategies while solving problems. Researchers at Stanford University have reported new evidence that developmental dyscalculia,a condition marked by ongoing trouble with arithmetic,may involve weaker control over attention, memory and flexible problem-solving as well as altered brain activity.
In a study published in JNeurosci, Oliver Lasnick and colleagues examined 68 children aged eight to 10 and found that those with developmental dyscalculia were less efficient than their peers at using different maths strategies. They took longer to switch methods, were less responsive to changes in difficulty and did not get better at choosing the most effective approach over time. The researchers said this suggests the disorder is not just about knowing number facts, but about the broader mental systems children use to plan, adapt and monitor their work.
The findings fit with earlier research showing that children with developmental dyscalculia are often slower and less accurate on simple addition and subtraction tasks, especially subtraction. Studies published in journals including Developmental Cognitive Neuroscience and indexed in PubMed have also reported heightened activity in parietal, occipito-temporal and prefrontal brain regions, pointing to atypical connectivity in networks linked to arithmetic. In the new Stanford work, brain-system activity differed between children with dyscalculia and those who used strategies more effectively, and could help predict how well children counted and shifted between approaches.
The researchers said the results underline the wide variation seen in dyscalculia and reinforce the idea that the condition reflects difficulties across several cognitive and neural processes rather than a single fault. That matters for parents and teachers because it suggests some children may need support that goes beyond extra practice, including teaching strategies step by step and reducing the demand on working memory. Cleveland Clinic describes dyscalculia as a learning disability that can affect counting, recognising numbers and understanding mathematical concepts, and notes that practical tools such as tangible objects and real-life examples may help children build confidence.
