Abstract:

Previous studies consistently found that the language processing system plays different roles in different kinds of numerical systems. Specifically, language processing influences the exact number system, whereas, there is no relationship between language and either the approximate number system or small number system. The mechanism underlying these relationships remains unclear. Recent behavioral and brain researchers have explored the reliance of numerical processing on language by using different paradigms such as longitudinal tests, language switching, dual tasks and phonological length operation within the same language.. However, these studies have not reached a consensus. Here we propose a novel explanation for this inconsistency from a perspective of memory mediation. Future research should include the number system development trace of children during their language-acquiring age. In addition, more studies should be done to see how long term and short term memory systems have effect on the relationship between language and number, how semantic and grammar influence number system, and to investigate the cognitive and neural basis of four basic number operations.

Key words: approximate number system, exact number system, language system, working memory, long-term memory
