Parafoveal activation of sign translation previews among deaf readers during the reading of Chinese sentences

In the present study, we manipulated the different types of information available in the parafovea during the reading of Chinese sentences and examined whether deaf readers could activate sign translations of Chinese words during reading. The main finding was that, as compared to unrelated previews, the deaf readers had longer fixation durations on the target words when sign-phonologically related preview words were presented; this preview cost effect due to sign-phonological relatedness was absent for reading-level-matched hearing individuals. These results indicate that Chinese deaf readers activate sign language translations of parafoveal words during reading. We discuss the implications for notions of parafoveal processing in reading.
