Number rules, learned procedures and verbal or symbolic calculation contribute to the task.

What research really says about Abacus & the brain.
Mental-Abacus training has been studied through behavioural tests and brain imaging. The strongest evidence is around arithmetic fluency, visuospatial working memory and the visual strategies used during mental calculation.

THE SHORT ANSWER
Is Abacus learning good for a child's brain?
Research supports a cautious yes for specific skills. Mental-Abacus training is associated with stronger arithmetic performance and visuospatial working-memory skills in several studies, and neuroimaging shows that trained calculation uses brain networks involved in visual and spatial processing.
- Evidence is strongest for arithmetic skill and visuospatial working memory.
- Brain-imaging studies show different activation patterns during mental-Abacus calculation.
- Some studies report structural or functional brain changes after sustained training.
- Results vary by age, training quality, duration and study design.
HOW IT WORKS
One tool. Two complementary kinds of processing.
The popular “left brain vs right brain” picture is an oversimplification. In real brains, calculation and visualisation depend on distributed, interacting networks. Mental-Abacus training is interesting because it adds a strong visuospatial strategy to arithmetic.
Illustrative concept — not a literal map of brain function.Visuospatial processing
Skilled learners can picture an Abacus and manipulate imagined bead positions while calculating.
Integrated networks
Research points to coordinated frontal, parietal and occipital regions rather than a simple one-hemisphere explanation.
THE EVIDENCE
What modern neuroscience has found.
A plain-language summary of peer-reviewed findings — including limitations, not just positive headlines.
Mental-abacus training uses a visuospatial strategy
A 2020 neuroscience review reports that trained mental-abacus calculation relies heavily on frontal-parietal visuospatial networks, while conventional calculation more often recruits language-related networks.
Frontiers in Neuroscience, 2020 ↗Arithmetic and visuospatial working memory can improve
In a five-school-year study, children receiving abacus-based mental-calculation training outperformed controls on arithmetic and visuospatial working-memory tasks, although the authors described the broader transfer effects as limited.
Journal of Neuroscience, 2019 ↗Shorter training also showed a working-memory signal
A 2025 quasi-experimental study of 190 schoolchildren reported significant improvement in the trained group on measures related to visuospatial working memory after four months, with small effect sizes and a call for longer-term research.
PLOS ONE, 2025 ↗WHERE THE SCIENCE IS HONEST
Promising does not mean guaranteed.
Abacus training is not a proven shortcut to higher general intelligence, and no responsible study can promise the same cognitive gain for every child. The 2020 review explicitly calls for caution when generalising results, and the 2025 PLOS ONE study reported small effect sizes and recommended longitudinal research.

Educational psychology researcherHer published work examined how abacus learning affected calculation performance and how mental-abacus representations relate to digit memory. Findings support strong calculation fluency, while also showing that transfer to other methods is not automatic.
