Abstract
Prelingually, profoundly deaf individuals, due to their hearing impairment, would not be expected to have the same access to phonological information as hearing individuals. They might therefore have difficulties in using phonological structure to relate different morphological forms of words. Deaf and hearing readers' sensitivity to the morphological structure of English words was tested in the present study by using a lexical decision (word/nonword classification) task. Target words were primed 10 trials earlier by themselves (e.g., think primed by think), by morphologically related words (e.g., think primed by thought), or by orthographically related words (e.g., think primed by thin). Response times of both hearing and deaf college students to target words were facilitated when primed by themselves and also when primed by morphological relatives. Response times of subjects in neither group were facilitated to targets primed by orthographically related but morphologically unrelated words. These results indicate that deaf readers, like hearing readers, are sensitive to underlying morphophonological relationships among English words.
