Mental abacus (MA) is a technique of performing fast, accurate arithmetic using a mental image of an abacus; experts exhibit astonishing calculation abilities. Over 3 years, 204 elementary school students (age range at outset: 5-7 years old) participated in a randomized, controlled trial to test whether MA expertise (a) can be acquired in standard classroom settings, (b) improves students' mathematical abilities (beyond standard math curricula), and (c) is related to changes in basic cognitive… Expand
Effects of mental abacus training over cognitive flexibility: An exploratory study
Mental Abacus (MA) training teaches students to solve math problems by visualizing a physical abacus structure to perform arithmetic operations. Research shows that MA practice relates with enhancedExpand
A One-Year Classroom-Randomized Trial of Mental Abacus Instruction for First- and Second-Grade Students
TLDR
It is found that first-grader students struggled to achieve abacus expertise over the course of the year, while second-graders were more successful, and the results suggest caution in the adoption of MA as a short-term educational intervention. Expand
Chinese kindergarteners skilled in mental abacus have advantages in spatial processing and attention
Abstract Previous studies have demonstrated that mental abacus learning could be helpful in improving mathematical skills. We hypothesized that kindergarteners skilled in mental abacus would haveExpand
Training on Abacus-Based Mental Calculation Enhances Visuospatial Working Memory in Children
TLDR
It is found that AMC training enhanced V SWM in children, which was accompanied by altered activation in frontal, parietal, and occipital areas, and it is observed that activation in right middle frontal gyrus played a significant mediation role in the transfer of AMC training to VSWM. Expand
Does the Japanese abacus improve underachieving children's performance in mathematics?
TLDR
The results show that children who participated in the abacus sessions have progressed at an average rate of 40% against the control group of 8%. Expand
A Review of the Effects of Abacus Training on Cognitive Functions and Neural Systems in Humans
TLDR
Findings from previous behavioral and neuroimaging studies about AMC experts as well as children and adults receiving AMC training are reviewed and suggests that AMC training has the potential to enhance various cognitive skills including mathematics, working memory and numerical magnitude processing.

The Chinese abacus was invented 1800 years ago as a piece of calculation equipment for economic education and support. The abacus no longer serves as an economic tool but has emerged as a powerfulExpand
A Feel for Numbers: The Changing Role of Gesture in Manipulating the Mental Representation of an Abacus Among Children at Different Skill Levels
TLDR
It is suggested that for intermediate and advanced learners, motor-spatial representation through abacus co-thought gestures may complement visual-sp spatial representation of a mental abacus to reduce working memory load. Expand
Children skilled in mental abacus show enhanced non-symbolic number sense
Mental abacus is mental arithmetic with the help of an imagined abacus. Children skilled in mental abacus have been shown to exhibit top-quality arithmetic abilities. The current study investigatedExpand
Intensive Math Training Does not Affect Approximate Number Acuity: Evidence From a Three-Year Longitudinal Curriculum Intervention
TLDR
While the present study replicated past work finding correlations between approximate number acuity and math success, these correlations were very small when other domain-general capacities were considered, and there was no evidence that changes to math performance induced changes to approximateNumber acuity, militating against one class of causal accounts.

Representing exact number visually using mental abacus.
TLDR
The structure of the representations underlying MA in a group of children in India is investigated, suggesting that MA is represented in visual working memory by splitting the abacus into a series of columns, each of which is independently stored as a unit with its own detailed substructure. Expand
Numerical processing efficiency improved in children using mental abacus: ERP evidence utilizing a numerical Stroop task
TLDR
The results suggest that AMC training can strengthen the relationship between symbolic representation and numerical magnitude so that numerical information processing becomes quicker and automatic in AMC children. Expand
Numerical processing efficiency improved in experienced mental abacus children
TLDR
The results showed that experienced MA children were less influenced by physical size information when intentionally processing numerical magnitude information, but they were more influenced than their peers by numerical magnitude Information when intentionallyprocessing physical size Information. Expand
Different components of working memory have different relationships with different mathematical skills.
TLDR
Visual-spatial sketchpad (VSSP) functioning predicted unique variance in magnitude judgments and number writing, which is consistent with the VSSP having a role in the development of number writing and magnitude judgments but a lesser role in early arithmetic. Expand
Adaptive training leads to sustained enhancement of poor working memory in children.
TLDR
Findings indicate that common impairments in working memory and associated learning difficulties may be overcome with this behavioral treatment. Expand
Putting brain training to the test
TLDR
Although improvements were observed in every one of the cognitive tasks that were trained, no evidence was found for transfer effects to untrained tasks, even when those tasks were cognitively closely related. Expand

Although math anxiety is associated with poor mathematical knowledge and low course grades (Ashcraft & Krause, 2007), research establishing a connection between math anxiety and math achievement hasExpand
Enhanced white matter tracts integrity in children with abacus training
TLDR
It is suggested that long‐term AMC training from an early age may improve the memory capacity and enhance the integrity in white matter tracts related to motor and visuospatial processes. Expand
No evidence of intelligence improvement after working memory training: a randomized, placebo-controlled study.
TLDR
This study compared young adults who received 20 sessions of practice on an adaptive dual n-back program or an adaptive visual search program with a no-contact control group that received no practice, and found no positive transfer to any of the cognitive ability tests. Expand
The Roles of the Central Executive and Visuospatial Storage in Mental Arithmetic: A Comparison across Strategies
TLDR
Investigating the impact of a dynamic spatial n-back task and tasks loading the visuospatial sketchpad and central executive on adults’ use of counting, decomposition, and direct retrieval strategies for addition suggest that maintaining visUospatial information in mind is required when adults solve addition arithmetic problems by any strategy but the role of domain-general executive resources is much greater than that of the Visuosp spatial sketchpad.
