Syntactic Processing of Text Reading for People Who are Deaf and Hard-of-Hearing:Qualitative or Quantitative Difference?
Text-reading ability is required for people who are deaf and hard-of-hearing to access external information and integrate into society.However,the reading comprehension scores of deaf readers are lower than those of hearing readers.After high school graduation,the average reading comprehension levels of deaf readers are comparable to those of hearing readers in the fourth grade of primary school.According to the results of the language proficiency test,the syntactic awareness deficit is one of the reasons for the reading difficulties of deaf readers.Syntactic awareness contributes more to the reading comprehension of deaf readers than other linguistic or non-linguistic factors.Nevertheless,it is unclear whether the deficit in syntactic awareness may affect the syntactic processing and whether deaf readers have access to syntactic information when reading text.Currently,two distinct perspectives exist.First,there is a qualitative difference in syntactic processing between deaf readers and hearing readers.Syntactic violations in sentences have not elicited a P600 effect for deaf readers.In contrast,only the N400 effect accurately predicted their reading performance.This study has revealed that deaf readers have neglected syntactic information and prioritized semantic information for comprehension.The second perspective is a quantitative difference whereby deaf readers activate syntactic information automatically,yet it takes them longer and is less accurate.Despite the uncertainty over whether the syntactic processing of deaf readers has undergone a qualitative or quantitative change,it is indisputable that the sentence processing speed and accuracy of deaf readers are lower than those of hearing readers as a result of the impairment of their syntactic processing ability.What would this difference occur?The word processing efficiency hypothesis in previous studies has suggested that deaf readers show improvement in visual compensation due to their hearing loss,thereby increasing their perceptual span.Deaf readers can process semantic information,such as orthography,more quickly,which can impede syntactic processing.What is the extent of compensation provided by the visual area and other brain areas?Findings reveal that individual differences,such as prior experience with sign language and working memory capacity,influence the syntactic processing of deaf readers.Future research is expected to focus on the syntactic processing mechanisms in deaf readers from four directions.First,it can investigate the neural basis of deaf readers'syntactic processing at the space-time level from the perspective of brain function compensation.Second,for the experimental design,future studies could choose a paradigm that is more suitable for speech impairment and Chinese characteristics.Third,regarding individual differences,it is essential to examine the effect of oral experience on executive functioning.Lastly,it should create sign bilingualism and co-enrollment environments and control groups that are suitable for interventions.
