Abstract: Abacus is a complete brain development program used by Chinese, Japanese, Malaysians and Koreans to improve mathematical skills. The improvement in mathematical skills is due to a coordinated functioning of both right and left brain hemisphere. As learning and memory in any field is achieved by coordinating and analyzing the different sensory inputs, whether an abacus trainee would also improve the short term memory as a whole was evaluated in our study. 50 children of average IQ between 7 and 12 years from 2 regular schools and 50 from an abacus institute were evaluated for short term memory before and after a period of one and two years. The memory tests were taken from Wechsler memory scale, Mini mental state examination, Mann Buitar visual memory screen for objects. The results showed that the abacus learners at the end of one and two years had a better visual and auditory memory with ability and positive attitude when compared to non abacus learners.
