Luria's functional organization of the brain, and views on language, h
ave influenced major developments in conceptualizing cognitive process
es and linguistic abilities; research by a Canadian group in these are
as is presented in this paper. Aspects of language such as paradigmati
c and syntagmatic associations, and the failure to acquire phonologica
l coding, are considered in several empirical studies. The theoretical
context for them is provided by a theory that considers four primary
cognitive processes: planning, arousal-attention, simultaneous and suc
cessive processing. The theory provides an understanding for linguisti
c development in children which is a significant extension of Luria's
clinical work. It confirms the validity of the four cognitive processe
s outside the clinical population.
