Age-sensitive associations of segmental and suprasegmental perception with sentence-level language skills in Mandarin-speaking children with cochlear implants.
Earlier cochlear implant surgery leads to better consonant, tone, and sentence skills in Mandarin-speaking deaf children.
01Research in Context
What this study did
Tian and team tested 42 Mandarin-speaking kids. Half had cochlear implants. Half had normal hearing.
They checked how well each child heard consonants and tones. Then they asked kids to repeat sentences.
Kids ranged from 3 to 7 years old. The team noted age at implant surgery for each deaf child.
What they found
Children with implants scored lower on every task. They missed more consonants. They mixed up tones.
Sentence repetition was hardest. Kids with earlier implants did better. Each month of delay hurt scores.
The gap grew with age. Older implanted kids fell further behind in both sound skills and sentence use.
How this fits with other research
Phillips et al. (2014) also tested deaf preschoolers. They focused on IQ tests, not language. Both studies show we need careful, multi-part assessment for this group.
Jelsma et al. (2015) found kids with motor delays learn slower. Tian shows the same pattern in language. Clinical groups need more practice time across domains.
Unlike Kim et al. (2023) who used brain scans to classify autism ASD, Tian used simple speech tasks. Both prove you can spot delays early with the right tools.
Why it matters
If you work with deaf children, push for implant surgery before 24 months. Then track consonant, tone, and sentence skills every six months. Use short, Mandarin-specific tasks like those in this paper. Early action plus close monitoring gives these kids their best shot at normal language growth.

03Original abstract
BACKGROUND AND AIM: It remains unclear how recognition of segmental and suprasegmental phonemes contributes to sentence-level language processing skills in Mandarin-speaking children with cochlear implants (CIs). Our study examined the influence of implantation age on the recognition of consonants, lexical tones and sentences respectively, and more importantly, the contribution of phonological skills to sentence repetition accuracy in Mandarin-speaking children with CIs. METHODS: The participants were three groups of prelingually deaf children who received cochlear implants at various ages and their age-matched controls with normal hearing. Three tasks were administered to assess their consonant perception, lexical tone recognition and language skills in open-set sentence repetition. RESULTS: Children with CIs lagged behind NH peers in all the three tests, and performances on segmental, suprasegmental and sentence-level processing were differentially modulated by implantation age. Furthermore, performances on recognition of consonants and lexical tones were significant predictors of sentence repetition accuracy in the children with CIs. CONCLUSION: Overall, segmental and suprasegmental perception as well as sentence-level processing is impaired in Mandarin-speaking children with CIs compared with age-matched children with NH. In children with CIs recognition of segmental and suprasegmental phonemes at the lower level predicts sentence repetition accuracy at the higher level. More importantly, implantation age plays an important role in the development of phonological skills and higher-order language skills, suggesting that age-appropriate aural rehabilitation and speech intervention programs need to be developed in order to better help CI users who receive CIs at different ages.
