This review is followed by an examination of the major criticisms associated with each theory. Finally, a call for a more sophisticated analysis of the complex relationship between cortical and subcortial structures and language processing and production is presented. This call highlights the need to examine the areas of listening, memory, and information retrieval.
In the past years a number of Speech Communication scholars have turned to neurophysiological research to provide insight and clarity in to the way humans process linguistic stimuli. These speech-oriented studies have been vital in explaining the structure / function relationship of brain and language. However, now that the 'basic" introduction to the area of neurophysiology has been accomplished, it may be time to reevaluate the general principles we have adopted whole heartedly from early neurological studies. If an accurate assessment of language processes is to be achieved, a more sophisticated analysis of the intricacies of the brain, and that entity's role in the production of speech need to be considered. It is no longer appropriate to generalize about language functions and cortical structures. Language and Reading scholars should strive for specificity.
