There is psychological and neurobiological evidence that number and language processing present some specificities and may dissociate after brain damage. Furthermore, animals and babies seem to be able to discriminate small numerosities in a non-symbolic way. However, one of the specificities of the human species is the development of language and symbolic processes. The acquisition and development of arithmetic is thus bound to the acquisition of language and symbolic notations.In this sp...

In particular, Piaget’s work on conservation, including conservation of number, profoundly influenced developmental psychologists who, working first in the Piagetian theoretical framework, began to discover a broader set of topics in mathematical cognition. In developmental psychology, the field continued to ...
