Background: Intervention studies aimed to improve the written production of single words by persons with aphasia have yielded promising results and there is growing interest in interventions targeting text writing. The development of technical writing aids offers opportunities for persons with aphasia, and studies have shown that using them can…

Connectionist theories of language propose that written language deficits arise as a result of damage to semantic and phonological systems that also support spoken language production and comprehension, a view referred to as the "primary systems" hypothesis.

The purpose of this article was to examine a behavioral treatment sequence for such individuals intended to strengthen phonological processing and links…

This study evaluates spelling errors in the three subtypes of primary progressive aphasia (PPA): agrammatic (PPA-G), logopenic (PPA-L), and semantic (PPA-S). Forty-one PPA patients and 36 age-matched healthy controls were administered a test of spelling. The total number of errors and types of errors in spelling to dictation of regular words,…

Separate experiments investigated parietal lobe malfunction; developmental v acquired dyslexia; whole-word, syllabic, and alphabetical reading ability; phonological recoding; and spelling. Reading processes and memory of normal and aphasic children were compared. (CP)
