![]() ![]() The neural correlates of mental calculation were also explored in children with AMC training. These differences may indicate that more visuospatial/visuomotor imagery processes are involved in mental calculation for AMC experts compared with nonexperts. ![]() ![]() The right frontoparietal areas, especially the posterior superior parietal cortex, were significantly activated in the AMC experts compared with the controls during numeral mental-operation tasks. The neural correlates associated with three mental-operation tasks (numeral, spatial, and verbal) were compared among experts and controls. provided direct evidence that mental calculations by adult abacus experts experts primarily depended on brain areas involved in visuospatial imagination. Moreover, a very important study by Hanakawa et al. Summary of the studies:Ĭompared to other subjects, the abacus-trained kids showed higher activity in the right posterior superior parietal lobule/superior occipital gyrus and the right supplementary motor area in both tasks. In addition, the mental abacus skills can be used to develop number concepts, increase efficiency in mathematical calculations, get substantial gains in numerical processing efficiency, and enhance the ability of students to apply mathematical skills to real-life scenarios. The studies have revealed that the proper Abacus training may result in qualitative changes in a child’s ability to represent numerical information through the development of a “mental abacus” and improve response inhibition. It certainly is an impressive and efficient approach, with the concentration, intensity and speed being very impressive.Įven though, Abacus is an ancient way of performing calculations, more research has been conducted in the recent years only especially on the mental abacus abilities helps the kids in enhancing the memory and other cognitive skills. So, what is so special about this mental abacus training? It is represented in visual working memory of an Abacus student by splitting the abacus into a series of columns, each of which is independently saved as a unit with its own detailed substructure. Why would one need to master mental abacus techniques? Children do these calculations in the physical rod and with constant practice and training, they can imagine an abacus in mind and perform arithmetic operations on a virtual abacus rapidly and precisely. Abacus, a tool which consists of beads and rods, can be used to do complex arithmetic operations, such as addition, subtraction, multiplication, division, square root and cubic root. ![]()
