Comparison of Definitional skills in school-age children with cochlear implants and normal hearing peers

The auditory experience is important because makes a major contribution to the development of speech, language, cognitive, and social skills. Knowledge of the lexicon has been increased throughout life. Input factors and linguistic and metalinguistic knowledge are effective factors in the acquisition of definitional skills. This study was done to investigate definitional skills in cochlear-implanted (CI) children and their typically developing (TD) peers. A total of 46 third-grade primary school children (16 with cochlear implants and 30 their TD peers) were recruited. The verbal definitional task included 14 common high-frequency nouns and 11 common high-frequency verbs. All definitions were scored for both content (semantic) and grammatical forms.
