Using a non-speech-specific measure of prosody, rise time perception, Goswami and her colleagues have found that individuals with dyslexia perform significantly worse than nonimpaired readers. Studies have also found that children and adults with specific language impairment were impaired on these tasks. Despite the high comorbidity of these…

The integrity of phonological representation/processing in dyslexic children was explored with a gating task in which children listened to successively longer segments (gates) of a word. At each gate, the task was to decide what the entire word was. Responses were scored for overall accuracy as well as the children's sensitivity to coarticulation…

A word-learning task was used to investigate variation among developmental dyslexics classified as phonological and surface dyslexics. Dyslexic children and chronological age (CA)- and reading level (RL)-matched normal readers were taught to pronounce novel nonsense words such as "veep." Words were assigned either a regular (e.g., ''veep'') or an…

Administered phonological awareness and phoneme identification tasks to dyslexic children and chronological age (CA) and reading-level (RL) comparison groups. Found no real differences in categorical perception between dyslexic and RL groups; however, more dyslexics (7 of 25) had abnormal identification functions. Results suggest that some…

Analyzes the spelling errors of third graders who fit phonological and surface profiles of developmental dyslexia along with the errors of younger (reading level matched) and chronologically age matched non-dyslexic comparison groups. Finds that different types of dyslexics produce different types of errors and that children produce spelling…

This study examined differences between two subgroups of third grade dyslexics (n=72), either phonological dyslexics (lower phoneme awareness and expressive language) or delayed dyslexics (slower at processing printed words and letters but not at rapid automatic naming). Re-testing in fourth grade revealed that this classification produced…

This study investigated the relationship between dyslexia and speech perception, phonology, and morphology among 7-, 8- and 9-year-olds. Findings indicated that only the developmentally language impaired showed clear speech perception deficits. Phonological dyslexics and developmentally language impaired showed inflectional morphology…

Assessed development of word recognition and spelling in dyslexic children (ages 9-15) over a 2-year period. Found that phonological and orthographic processing are distinct but reciprocally related components. Argues that dyslexics have primary deficits in phonological processing of speech and print and secondary deficits in orthographic…

Compares use of two decoding strategies in fifth-sixth grade normal and dyslexic children, and younger normals reading-aged-matched to the dyslexic students. Finds dyslexics lag behind age-matched normals in use of both strategies, and behind reading-age-matched normals in use of analogies, but not rules. (RS)

This study used computer word games to train 35 dyslexic readers (mean age 13 years) in automaticity (speed and accuracy) of word recognition. After training, reaction time on the word vocalization and sentence comprehension tasks improved significantly for both trained and untrained stimuli. Results support the automaticity hypothesis. (DB)

Studied 51 dyslexic children, 51 age-matched normal readers, and 27 younger normal readers to explore whether there are different subtypes of developmental dyslexia, and whether developmental dyslexia represents delay or deviance. Found evidence to support two subtypes: surface and phonological dyslexia. (DR)

Forty normal readers and 50 dyslexic children (age 9-14) were matched on reading level and intelligence quotient and tested. Analysis revealed 3 major subgroups: specific deficit in phonological processing of print (52 percent), deficits in processing both the phonological and orthographic features of printed words (24 percent), and phonological…

Investigates whether dyslexic children use word identification processes which are qualitatively different from those used by normal readers at the same stage of reading acquisition. Results suggest that dyslexics and normal readers use essentially the same processes to recognize words, but may differ in knowledge of correspondence rules. (RWB)

Although evidence is accumulating that the major reading difficulty dyslexics experience involves decoding and recognizing printed words, it is not clear that all dyslexics read poorly for the same reasons. A study investigated dyslexic children between 7 and 14 years of age to see if their reading errors and patterns of performance would enable…
