Hearing-impaired students are more susceptible to the outside interference information in reading chapter content. It will reduce their reading speed and reading scores indicators and their reading ability is affected. Therefore, it is very important to suppress jamming irrelevant information research for hearing-impaired students' reading development. Inhibition mechanism is an important cognitive processing mechanism, but what is the role of inhibition mechanism, yet there is a big controversy. Functions and roles of working memory structure of the system is to read one of the main direction of inhibition mechanism in the research, many studies have shown that the hearing-impaired students' working memory capacity is small, processing and storage of information ability is bad, they are the same age average as hearing students, there is a big gap between the different working memory capacity and ability of inhibition of whether the hearing-impaired students can make a big difference. Therefore, this study from the perspective of different interference, to inspect different working memory capacity of the hearing-impaired students in discourse reading suppression characteristics. Choose the Chinese discourse as the experimental material, to explore the inhibition mechanism of hearing-impaired students in reading. This research includes three experiments:The first experiment is to investigate different working memory capacity group of the hearing-impaired students and hearing students to suppress irrelevant information in discourse reading ability if there are differences. The study found that hearing-impaired students and hearing students both be influenced by the interference information. Hearing students' inhibition ability is higher than the hearing-impaired students. Different working memory capacity of the hearing-impaired students' inhibiting ability is significant difference in reading. High working memory capacity group of the hearing-impaired students'inhibiting ability is stronger, low working memory capacity of the group of the hearing-impaired students is weaker.The second experiment is to explore the influence of different meaning materials for different working memory capacity of the hearing-impaired students in suppressing the irrelevant information in reading. And analysis the hearing-impaired students specific suppression of interference information process in which a stage. The study found that different interference of material has a different influence of different working memory capacity of the hearing-impaired students. Low working memory capacity group of hearing-impaired students are greatly influenced by the disturbance of material significance. High working memory capacity group hearing-impaired students are less affected by the disturbance of material significance. Interference materials has a great influence on the inhibiting ability. For the hearing-impaired students, the interference of meaning has a significant impact. The none meaningful material is more difficult than the meaningful materials. Inhibition ability of hearing-impaired students in reading mainly occurred in the process before the inhibition mechanism of action. The results consistent with Connelly and others' idea.The third experiment is to explore the influence of different location materials for different working memory capacity of the hearing-impaired students in suppressing the irrelevant information in reading. And continue to analysis the hearing-impaired students' specific suppression of interference information process in which one phase. The study found that the predictive of the interference materials location for different working memory capacity of the hearing-impaired students will have much impact. Low working memory capacity group of the hearing-impaired students are greatly influenced by the interference material position. High working memory capacity group of the hearing-impaired students have little effect on interference material position. The predictive of the interference materials location for inhibition also play a great influence. For the hearing-impaired students, random Location material is harder than fixed location reading material. Questions about the role of inhibition process, the experiment results are same as the second experiment, in favor of Connelly and others' idea.
