Examines the consonant substitution, sequencing, omission, and addition errors of severely reading disabled teenagers in recognizing consonants in orthographically regular nonwords, and compares the results with responses to identical stimuli by normal children of the same age and reading level groups. (Author/DJD)

Compared the vowel responses of severely disabled readers with those of normal control children in reading orthographically regular nonwords. Vowel responses were compared on both age and reading level groups, and the vowel responses of two out of three reading disabled groups paralleled those of their reading level peers. (Author/DJD)

Two studies were conducted to determine whether the consonant errors displayed by readers with severe reading disabilities are the result of phonetic rather than visual substitutions. In the first study, the reading and spelling performance of three groups of readers with average IQs but with reading levels two years below grade level, was…
