Karl-Heinz Graß (KFU, advisor B. Thaller): Geometry and Arithmetic: Theoretical Analysis and Empirical Investigation to Spatial and Basic Numerical Influences on Arithmetic

Abstract: Spatial skills are highly related to success in mathematics and science. However, little work has been done to investigate the cognitive pathways by which the relation between spatial skills and arithmetic emerges. Neurological and cognitive studies indicate positive correlations between spatial abilities and mathematical skills, especially arithmetic skills. We investigate which types of spatial exercises and which components of spatial imagination play a crucial role in connection with arithmetic skills. Furthermore we hypothesize that spatial imagination indirectly influences arithmetic skills via basic numerical processing skills. We test this hypothesis using a cross-sectional dataset including approximately 100 children between the ages of 9 and 11 with different socio-economic backgrounds.
In this presentation we give a short overview about the underlying theories, the developed test battery, the statistical methods used, and the results of the examination.[hide abstract]
