The difference in error types are theorized to be due to neurological deficits affecting different stages of sentence processing, with paragrammatic speech errors occurring later in the sentence formulation processing. Paragrammatic errors may or may not occur in writing as well as in speech due to: (1) presumed differences in the neural circuits responsible for the two functions, (2) differences in the organization of these skills in the brain, and (3) the...
