Simultaneous Synthesis, Regulation, and Arithmetical Performance

Abstract

This study examined arithmetical performance in relation to Luria's theory of the functional organization of the brain and Das, Kirby, and Jarman's model of simultaneous-successive processes. It was found that both computation and problem solving are related to simultaneous synthesis and behavior regulation factors. However, tests of problem solving and quantitative ability loaded higher on the simultaneous synthesis factor than on the behavior regulation factor, while the computation test loaded higher on the regulation factor than on the simultaneous synthesis factor.
