This article argues that word finding problems of children with dyslexia reflect deficits that underlie both naming and reading problems. Research on the co-occurrence of reading and word finding problems is reviewed, and a four-phase research program is reported. Findings focus on the causal relationship between naming speed deficits and reading…

Research findings from autopsy studies, neuroimaging, functional imaging, and electrophysiological measures specific to dyslexia have provided a better understanding of the reading process, particularly as it applies to individuals with dyslexia. Evidence from these studies pertaining to the neurological origins of dyslexia is reviewed, and…

This article considers differences between good and poor spellers and concludes individual differences in spelling ability are the result of differences in the knowledge of sound-spelling information rather than differences in visual memory abilities.

A conceptual framework for designing a comprehensive assessment battery is presented with specific attention to the relationship between…

This discussion of speech and language development in individuals with nonverbal learning disabilities (NLD) reviews NLD assets, deficits, and dynamics; the white matter model; manifestations of NLD in neurological dysfunction; psycholinguistic dimensions of NLD in terms of language content, form, and use; developmental considerations in NLD; and…
