Recent research from Stanford University uncovers neural and behavioural variations in children with dyscalculia, suggesting personalised support may be essential for effective maths learning.
Children who struggle persistently with maths may be showing more than a gap in classroom practice, according to new research from Stanford University that points to differences in both problem-solving behaviour and brain activity. The study, published in JNeurosci and led by Oliver Lasnick, focused on developmental dyscalculia, a condition that affects the ability to work with numbers and is thought to affect a small but meaningful share of school-age children.
In a group of 68 children aged eight to 10, the researchers found that those with developmental dyscalculia were less adept at choosing between maths strategies. They changed methods more slowly, were less responsive when tasks became harder and did not become better over time at selecting the most effective approach. The researchers also reported that patterns of brain-system activity differed from those seen in children who were more skilled at strategy use, and that these signals could help predict how well a child counted and switched between methods.
The findings fit with a broader wave of recent work suggesting that developmental dyscalculia is linked to more than simple weakness in arithmetic. Other studies have pointed to altered connectivity in resting-state brain scans, slower preparatory brain activity before tasks begin, and differences in attentional control and neural timing during arithmetic processing. Taken together, this body of research suggests that the condition may involve a wider network of cognitive and neural differences than previously appreciated.
Lasnick said the work also underlines how much variation there is within dyscalculia itself. That matters for parents and educators because it suggests children may need different forms of support, depending on whether the main difficulty lies in attention, memory, strategy choice or the speed of neural processing. The researchers say that understanding these underlying mechanisms could eventually help shape more targeted interventions for children who continue to struggle despite standard maths instruction.
