| Abstract | Investigated sensitivity to 2 types of orthographic structure (linguistically-based orthographic regularity and summed single-letter positional frequency) in 11 deaf undergraduates with good speech, 12 deaf undergraduates with poor speech, and 17 hearing undergraduates. Perception,
judgment, and reading tasks were administered to all Subjects. Findings show that sensitivity to orthographic regularity differed as a function of expertise in speech. In the perceptual task, deaf Subjects with good speech exhibited perceptual facilitation due to regularity that was comparable to that of hearing Subjects, while deaf Subjects with poor speech exhibited less facilitation than those in the other 2 groups. In the judgment task, judgments of the hearing Subjects were more influenced by regularity than those of deaf Ss with poor speech. |
