Dr Rakesh Sengupta, Assistant Professor, Psychology, SIAS, has co-developed DyscalcBattery, an open-source cognitive screening tool designed for dyscalculia screening and numerosity perception research.
Addressing a significant gap in learning disability research, DyscalcBattery offers a free, browser-based alternative to existing commercial screening tools that are often calibrated primarily for Western populations. Developed as an open-source platform, the tool is specifically designed for multilingual and low-resource field deployments, enabling researchers and educators to conduct cognitive screening using low-end laptops and tablets.
The tool is currently being used in a large-scale field study involving school children in Warangal, Telangana.
The preprint for the battery, DyscalcBattery: An open browser-based psychophysical battery for dyscalculia screening and numerosity perception research, co-authored by Dr Rakesh Sengupta, Assistant Professor, Psychology, SIAS and Usha Padmini, SR University, Warangal is now available online. The paper provides additional details on the development and implementation of the open-source screening tool.
