An alternative model for symbolic number processing
Goal: Symbolic and non-symbolic numbers are thought to be processed by an evolutionary ancient, simple representation, the Analogue Number System (ANS), which system is thought to be the very base of number understanding.
We offer an alternative account for symbolic number understanding, proposing a human specific, simple representation similar to a network of concepts or to the mental lexicon. It is a comprehensive model for symbolic number processing phenomena.
