A representational analysis of numeration systems

  title={A representational analysis of numeration systems},
  author={Jiajie Zhang and Donald A. Norman},
This article explores the representational structures of numeration systems and the cognitive factors of the representational effect in numerical tasks, focusing on external representations and their interactions with internal representations. Numeration systems are analyzed at four levels: dimensionally, dimensional representations, bases, and symbol representations. The representational properties at these levels affect the processes of numerical tasks in different ways and are responsible… CONTINUE READING
