A Study On Lexical Semantic Processing Of Deaf Students

Due to the limited information can deaf students get, not as easy as normal children, deaf students have several problems in word recognition, parsing, comprehension and writing. It is worth recognizing that what features in their semantic processing of vocabulary, how left and right hemispheres affected when they process the Chinese vocabulary semantic and whether the loss of speech perception affects the process of vocabulary semantic. Research in vocabulary semantic processing is helpful to grasping the key reason to the vocabulary learning problems, and meaningful to the Chinese language teaching, also, it’s significant to the language development of deaf students. Base on Chinese vocabulary, this essay is aimed at discuss the characteristics of deaf students’process of Chinese vocabulary semantic and the effect of left and right hemispheres.By adopting word recognition task, all the stimuli are reflected by the software named E-prime. There are three experiments as below:Experiment1:By using the task of recognize vocabulary to inspect deaf students’ ability of semantic processing and their features which three kinds of vocabularies had been used:synonym, antonym, and non-related words, the interval of starting a phrase and inspect a phrase is60ms,100ms and140ms separately. The purpose of this experiment is to inspect the features of deaf students’processing of vocabulary, and whether they can use font, meaning and pronunciation together to process, if they can, which one is accounted for the largest to process.Experiment2:By using the task of sentence supplementary to investigate deaf students’ability of processing vocabulary under the influence of context which four kinds of vocabularies had been used:correct words, synonym, antonym, and non-related words, the interval of starting a phrase and inspect a phrase is60ms,100ms and140ms separately. The purpose of this experiment is to recognize how context influence deaf students’to distinguish the meaning of words. Affected by the context of a sentence, whether it is influenced by the similar of shape or meaning, whether they can process the sentence and the meaning and what the features of the speed of process and the accuracy of the process.Experiment3:By using the task of combine the recognize vocabulary and tachistoscopic visual half-field technique to inspect how left and right hemispheres effected on vocabulary process which three kinds of vocabularies had been used: synonym, antonym, and non-related words, the interval of starting a phrase and inspect a phrase is Oms,50ms and100ms separately, and the render view divided into two parts: left and right. The purpose of this experiment is to investigate the how left and right hemispheres effected on vocabulary processing and the features and under the circumstance of lose phonetic empathy, what is the different of normal and deaf students’on the activation of the brain hemispheres language features, and how brain hemispheres affect vocabulary processing.In summary, this essay support conclusions as follow:(1) The way of deaf students to process Chinese vocabulary depends on the shape and meaning of the words, pronunciation has little effect on it. Meanwhile, there was an obvious mistake on word-formation, we support that it is related to the use of gesture language. This essay is also support the hypothesize of deaf person us directly-process to pick up familiar vocabularies.(2) Deaf students have a positive reflect on recognition words under context, context has an impact on the semantic processing. When context has been used, high semantic similarity words had been identified harder, by contrast, low semantic similarity words can be recognized easily.(3) The use of left hemisphere and the use of right hemisphere to process vocabulary have the same result. Although the loss of speech function slow down the development of left hemisphere, the usage of gesture language and vision make up to enhance the ability of vocabulary recognizing to the level as normal person does.
