summary | In their first year of life, infants possess two cognitive systems that encode numerical information : one system representing small and large numerosities as approximate analog magnitudes, and the second system tracking objects in small sets – and therefore, indirectly keeping track of their numerosity. The analog magnitude system is known to be functional in newborns (0-3 days of age). I will present several lines of research building on this first result, to provide a richer picture of numerical cognition at birth. A first series of experiments tested newborns’ ability to relate different types of magnitudes (numerosity, spatial extent, temporal duration). The other series of experiments tested whether newborns possess a specific system to encode small sets, as do older infants. |
