Models of Language Production
Willem Levelt outlined the currently accepted theory of speech production. The different components of production are displayed in the Figure 1. Words are produced after the concept waiting to be produced is conceptualized, related words are selected, encoded and the sound waves of speech are produced.
While there is a large amount of heterogeneity in phenotypes of children with expressive language disorder, in terms of impairment and of severity. We can use language models such as Willem Levelt's to propose that individuals of expressive language order have a block in one or more of the cognitive steps involved in language production.

“Today it is not the classroom nor the classics which are the repositories of models of eloquence, but the ad agencies.”
—Marshall McLuhan (1911–1980)
“French rhetorical models are too narrow for the English tradition. Most pernicious of French imports is the notion that there is no person behind a text. Is there anything more affected, aggressive, and relentlessly concrete than a Parisan intellectual behind his/her turgid text? The Parisian is a provincial when he pretends to speak for the universe.”
—Camille Paglia (b. 1947)
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
“In the production of the necessaries of life Nature is ready enough to assist man.”
—Henry David Thoreau (1817–1862)
