Phonological Processing, Verbal and Nonverbal Memory, and Attention in Dysphonetic and Dyseidetic Dyslexia.
Newby, Robert F.; And Others
The main aim of this study was to compare children diagnosed as dysphonetic and dyseidetic on a number of mental processing variables to determine if opposite patterns of relative strength and weakness between the groups could be documented. Another aim was to externally validate the diagnostic criteria, which were based on standardized clinical tests of reading and related abilities. Two matched groups of 8- to 11-year-olds were selected by means of historically conventional criteria for diagnosis of dyslexia. The dysphonetic group (N=31) had poor nonword decoding and limited phonetic skills in spelling unknown words. The group also had more regular word miscues in relation to irregular word miscues at frustration level than expected. The dyseidetic group (N=18) showed the opposite patterns. Measures of rhyming, word segmentation, phonological integration, orthographic and phonological processing, verbal and nonverbal memory storage and retrieval, and parent-rated and clinically-tested attention were given to each group. Reliable differences between the groups in higher-level phonological skills, and trends toward developmental differences in lower-level phonological skills and an orthographic and phonological double dissociation, supported the validity of the subgroups. Memory and attention measures did not differ between the groups. (RH)
