Cognitive and Neural Bases for Understanding Natural Numbers
This work reviewed recent empirical data on the existence of three distinct cognitive and neural systems behind our ability to understand natural numbers. The first system, specific to adult humans only, enables understanding of exact numbers and their flexible application in cardinal, ordinal and n...
