Reading
Do deaf readers need sound-based skills to read well?
Open access · cc by · source: Europe PMC
Deaf readers reached similar reading levels by different routes: oral deaf readers relied on English sound knowledge, while deaf native signers relied more on meaning-based memory.
Study at a glance
- Design
- Cross-sectional — Two deaf groups (oral deaf vs deaf native signers) compared on novel phonology tasks that separate spelling from sound knowledge, then regression/partial correlations predicting reading comprehension.
- N
- The participants section is missing from the available text, so the sample size per group is not stated; the same participants took part in both experiments, plus a separate hearing group used only to validate the tasks.
- Population
- Profoundly deaf adults: oral deaf individuals who use spoken English and deaf native signers of American Sign Language
- Outcome
- Accuracy on phoneme judgment and phonemic manipulation tasks; sentence-level reading comprehension (PIAT-R) and its predictors

Key findings
Both groups did worse when spelling was uninformative, but the signers were hit much harder, showing they leaned more on visual spelling to answer sound questions. The two groups did not differ in reading comprehension, non-verbal IQ, or memory span. Yet the predictors differed: in oral deaf readers, the 'deep' phonology score and serial recall span correlated with reading, whereas in native signers the primacy part of free recall (remembering the first words of a list, linked to meaning-based coding) and the spelling-based 'shallow' score did. The group-by-free-recall-primacy interaction was the only group difference in predictors.
Methodology
Oral deaf adults and deaf adults who grew up with American Sign Language did picture-based tasks where knowing how a word is spelled either helped, did not help, or actively misled a judgment about its sounds. This separated true sound (phonological) knowledge from spelling knowledge. The same people then completed a sentence-reading comprehension test, speechreading, syllable counting, serial recall and free recall tasks, and the researchers tested which measures predicted reading in each group after removing non-verbal IQ and degree of hearing loss.
Limitations
The available text does not include the participant description, so group sizes and recruitment cannot be checked here, and the groups were small enough that per-group correlations rest on few people. The design is correlational, so it cannot show that semantic memory causes better reading in signers; the shallow phonology score might simply reflect how much people read. Free recall was scored only in each person's preferred language, and missing data were filled with the mean. The findings concern adults with profound deafness and may not apply to deaf children learning to read.
