Research Progress on the Cognitive Neural Mechanism of Semantic Processing in Individuals With Hearing Impairments
Due to their auditory limitations,individuals with hearing impairments primarily rely on semantic processing during language development.Current neuroimaging and event-related potential studies have mainly focused on revealing the semantic processing in aspect of neural mechanism in individuals with hearing impairments.These studies have found significant activation in the right inferior frontal gyrus and superior temporal gyrus,as well as larger N400 effects and reduced N170 amplitudes in individuals with hearing impairments.Currently,the findings of these studies are inconsistent,suggesting that there are differences in the cognitive neural mechanism of semantic processing between individuals with hearing impairments and those with normal hearing.Future research should strengthen the common explanations of semantic processing in individuals with hearing impairments,understand its semantic processing and characteristics more deeply and specifically,and then put forward more effective educational intervention suggestions and methods for their language learning and development.
