Abstract:
BACKGROUND: At present, there are some researches on the cognitive identification of Chinese characters at home or abroad, however, most of them are based on the normal and healthy people.OBJECTIVE: To investigate the processing styles of optical information on phonemic code, graphic code and semantic code of Chinese haracters between hearing-disabled and normal people.DESIGN: Retrospective, observational and compared analysis based on the hearing-disabled as research subjects and the normal as the controlled group.SETTING: Department of education in a university.PARTICIPANTS: This study was completed in Xi' an between October 2001 and April 2002. With the mean age of 17 years and half in gender, 20hearing-disabled people, who were in grade 6 to grade 8, were selected from the Second School for the Deaf and Dumb in Xi' an. Inclusion criteria: The hearing loss of people was more than or equal to 92 dB. Exclusion criteria:People with acquired hearing-disabled were excluded. At the beginning of study in primary school, they were accepted oral training and taught Chinese pinyi, but gesture was the main communicated style in their daily life. With the mean age of 15 years and half in gender, 28 normal people, who were in grade 3, were selected from the No. 99 Middle School in Xi'an.METHODS: This study showed with serial opticum. The diagnostic method was compared with the cognitive identification of the three kinds of Chinese characters between the hearing-disabled and the normal respectively.phonemic code, graphic code and semantic code between hearing-disabled characters between hearing-disabled and normal people.RESULTS: The results showed that the function of graphic code in visual processing was strongly correlated with recognition of words of Chinese characters than the phoneme code and semantic code in both the hearing-disabled and hearing children. For hearing-disabled children, the alternative was the direct access that a semantic code was produced directly from a translation of the graphic code, however, the hearing children used the strategies of grapheme-phoneme conversion rules to interpret the meaning of words.CONCLUSION: The analysis of various results showe that no significant differences of mental processing are found between the hearing-disabled and hearing children. Perhaps both the direct access and the grapheme-phoneme conversion will be a comprehensive information processing activated each other.
