Abstract
A recent theoretical position (Goldberg & Costa, 1981) is employed as a framework for a neurodevelopmental model of central processing deficiencies in children. The model, which emphasizes differences between right-hemisphere and left-hemisphere systems, is shown to embrace a wide variety of behavioural phenomena that have been observed in normal children and in various subtypes of learning-disabled children. Dynamic factors operative within the development of both normal and disabled learning are addressed and incorporated.
