Myklebust's cognitive structure hypothesis for 91 dyslexic students of Delft University of Technology
AbstractInvestigated various aspects of dyslexia in persons over age 15. A study of all spelling mistakes in written work of 626 secondary school pupils resulted in a diagnostic criterion. Data from 91 dyslexic college students, analyzed over 7 yrs, show that intelligence test profiles differed markedly, making possible a classification as dyslexic or nondyslexic with a certainty of 80%. Marked differences in intercorrelation patterns between subtests were found between the successful dyslexic students, dropouts, and engineers.
