Little attention has been devoted to date to the study of morphological knowledge in individuals with developmental dyslexia. The current study compares the ability of Hebrew-speaking adult dyslexic students and gradeschool children to analyze written words into their morphological components, using a linguistic analogy task. Two sets of monolingual Hebrew-speaking participants--152 typically developing gradeschool children and 38 undergraduate students diagnosed with reading disabilities--were administered the Morphological Analogies Task. Results indicate an early ability of normally developing children to perform morphological analogies, while the adult dyslexic group performed on par with 3rd and 4th grade. Error analysis revealed that the overwhelming majority of the erroneous responses in all grades involved morphological strategies rather than the associative semantic strategy. However, the adult dyslexic students had many more associative responses than the graderschoolers. This testifies to the reduced written morphological abilities of adult dyslexic students.
