Fingers count: The role of finger counting in adult numerical cognition

Summary/Abstract: Finger counting being present in vast majority of cultures, plays very important role in the mathematical cognition. The practice of finger counting had large impact on the development of mathematics in a form we all know. Both neuropsychological studies and recent developments in cognitive neuroscience show close relationship between numerical and finger representations. Educated adults sometimes use finger counting as a backup strategy in order to reduce working memory load e.g. in calendar calculations. Despite commonness of finger counting, there are considerable between cultural and interindividual differences in finger counting. Apart from its role in numerical cognition, relations between number representations and fingers lend strong support to the embodied cognition hypotheses showing clearly that abstract concepts of numbers are anchored in bodily representations.
