What counts? : cognitive development and arithmetical performance: the role of child- and environment-related factors

Knowledge about the influence both the child and the environment have on the development of arithmetical skills is important for the realization of optimal development possibilities for each child. This dissertation describes the role that various child- and environment-related factors play in the development of arithmetical skills and underlying cognitive skills, such as work memory. Particularly studied are children at the age of four to eight years. It is also investigated if training at preschool age can stimulate specific cognitive skills. This dissertation provides insight that can among others support early monitoring and the approach of arithmetical problems and underlying cognitive problems.
