Background and Aim: Children with severe and profound hearing loss have difficulties in communicating with others and educating at school. Effects of learning environment on children&aposs language skills have been recently focused and educating those students in ordinary schools has been proposed. According to this view, we compared perception of antonyms and synonyms as a semantic aspect of language in students of ordinary, integrated and special schools.
Methods: It was an analytic cross-sectional study. Three groups of students were enrolled: normal-hearing students of ordinary schools and hearing-loss students of integrated and specials schools. Each group consisted of 25 students in fifth grade of elementary schools in Tehran city. Two written tests were used. Subjects wrote synonyms and antonyms for each word in the tests.
Results: Results denoted significant differences between scores of normal-hearing and hearing-loss students and also between hearing-loss students of integrated schools and hearing-loss students of special schools (p<0.05). In all three groups of the students, perception of antonyms was better than antonyms (p<0.001). Speech processing rate in normal-hearing students were higher than both groups of hearing-loss students (p<0.001).
Conclusion: The differences between normal-hearing and hearing-loss students shows that similar to other language skills, perception of synonyms and antonyms as a semantic aspect of speech is related to the hearing conditions and type of education. Moreover, the differences between two groups of hearing-loss students represent that speech stimulants and interaction with normal-hearing children could improve semantic aspect of speech in hearing-loss students.
