THE PROJECT

At the roots of Spatial Numerical Association: From behavioral observation to neural basis, SNANeB

The SNANeB project is funded by the European Commission under the action “Marie Skłodowska-Curie Individual Fellowships (IF)”. Marie Skłodowska-Curie fellowships finance international mobility of experienced researchers of all ages, nationalities and scientific disciplines within European Countries or between a European country and a country outside Europe.  The goal of the Marie Skłodowska-Curie fellowships consists in giving researchers the chance to enhance their career by increasing international research experience and expanding new scientific competences.

Scientific background and aims

Only adult humans master complex math using symbols and language, but whenever their use is prevented, they can still represent numbers approximately. This approximate number sense emerges early in life and shows a pattern of similarities with the number sense of infants and animals. Uniquely human mathematical abilities appear to be scaffolded on this ontogenetically and evolutionarily ancient “number sense”.

A peculiarity of numbers is their strong association with space. Humans represent number on a left to right oriented Mental Number Line, with small numbers located on their left and larger ones on their right. Historically, the association between number and space has been considered a by-product of culture. Recent evidence reported a tendency to associate numbers and space in infants and newborns. Nevertheless, the researches that toss most uncertainties on the importance of language and symbolic thought for the origin of the spatial numerical association, SNA, come from comparative research. Evidence on the SNA in animals advocates that it originates from non-symbolic and biologically determined precursors, but these are still unknown.

This SNANeB project is focused on studying the SNA in day-old domestic chicks and monkeys, thus addressing its wellspring in the absence of language or culture and to unveil the neural basis of numerical cognition. A superior knowledge of neural representation of numbers will permit optimized designs of clinical applications to enhance numerical comprehension.
