The effect of operation type, operand-order and problem-size on processing simple arithmetic

Once learned, simple arithmetic facts are thought to be represented in a dedicated long term memory store, known as an arithmetic retrieval network. Although the existence of this network is generally agreed upon, the organisation and accessibility of it is not. The aim of the current study was thus to test the effect of operation type, presentation format and problem-size on the processing of simple arithmetic. In two separate experiments...
