RESEARCH ON ABACUS LEARNING & ITS IMPACT

Years of Abacus Research and extensive Abacus Data attracted educationists and scientists alike. One possible reason is that the abacus originated nearly 3000 years ago and provided a simple solution for handling complex calculations of ancient generations.

The remarkable speed and accuracy demonstrated by abacus users became an important subject of scientific study during the 20th century.

Research suggests that abacus technology and mental abacus calculation may positively influence brain development, especially functions associated with visualization and mental processing. Initially, this was considered a hypothesis, but later technological advances helped researchers collect measurable data.

Several researchers contributed significantly to understanding the impact of abacus training on children:

• Dr. Toshio Hayashi – Professor, Osaka Prefecture University, Director of RIAST
• Prof. Shizuko Amaiwa – Shinshu University, Faculty of Education
• Ms. Kimiko Kawano – Researcher, Nippon Medical School

Development of Human Brain

The cerebral neocortex does not fully function at birth. Appropriate stimulation during childhood helps develop neural pathways and supports overall growth.

Key Research Insights:

✔ The neocortex contains approximately 14 billion sensory and motor nerve connections.
✔ Brain activation occurs through continuous stimulation.
✔ Activities such as:

• Moving fingers
• Speaking aloud
• Coordinated actions

help stimulate multiple regions of the brain.

Role of Abacus Training

Abacus learning encourages:

• Finger movement
• Visual processing
• Concentration
• Coordination

According to Dr. Toshio Hayashi, introducing abacus learning at an early age may help activate developing brain functions.

“If children enjoy learning abacus and move the beads with interest and fun, they gain greater developmental benefits.”

Development of the Right Brain Through Mental Abacus

The human brain is commonly discussed in terms of:

Left Brain (Analytical Side)

• Reading & Writing
• Logical Thinking
• Mathematical Processing
• Sequential Learning

Right Brain (Creative Side)

• Visualization
• Creativity
• Spatial Awareness
• Imagination
• Artistic Skills

Mental abacus calculation involves visualizing the abacus internally and moving imaginary beads mentally to solve problems.

This approach led researchers to propose that mental calculation may encourage visual processing and mental imagery.

Modern studies using brain imaging and blood-flow measurement technologies have explored these effects further.

Mental Math Benefits:

✔ Faster calculation
✔ Better concentration
✔ Enhanced visualization
✔ Improved imagination

Improvement of Numerical Memory

Research observations found that abacus learners often showed:

Better Memory Performance

• Greater numerical recall
• Higher digit retention
• Improved accuracy

This happens because students mentally place numbers onto an imagined abacus while calculating.

According to Prof. Shizuko Amaiwa:

Abacus learners tend to retain numbers more effectively due to image-based calculation methods.

Rapid and Accurate Calculation Skills

One of the strongest benefits associated with abacus practice is:

Development of:

✔ Fast Calculation Speed
✔ High Accuracy
✔ Mental Calculation Ability

Students gradually begin solving mathematical operations mentally without needing a physical abacus.

Researchers observed that this may also support:

• Confidence in mathematics
• Flexible problem-solving approaches
• Faster arithmetic processing

However, repetitive practice may sometimes lead to boredom if training methods remain unchanged.

Verbal Thinking and Visualization

Most people perform calculations internally through verbal thinking:

Example:

100 − 7 = 93

Mental abacus introduces an alternative approach:

Image-Based Thinking

Students visualize bead movement instead of relying only on internal verbal calculation.

Potential outcomes:

• Better understanding of addition and subtraction
• Improved understanding of decimal systems
• Stronger visualization skills

According to Ms. Kimiko Kawano, visualization developed through abacus can sometimes support learning in other academic areas as well.
