Abstract:
Experiment 1: Hierarchical linear modeling of growth trajectories of three executive functions (inhibition; rapid automatic switching, RAS; and combined inhibition/switching) in typical readers and writers showed steady improvement of inhibition but leveling of RAS and inhibition/switching about fourth grade. In multiple regressions, RAS, entered after inhibition, contributed uniquely to literacy outcomes at every grade. Improvement of executive functions over the first four grades predicted literacy outcomes at fourth grade. Experiment 2: For children with dyslexia, executive functions explained less variance in literacy outcomes, and boys were worse in inhibition and inhibition/switching. Developmental, educational, and clinical significance of findings are discussed.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
