This study has three aims 1) To compare the language, cognitive and sensory functions of children with implantation between 12-18 months and 18-24 months with their normal hearing peers, 2) To compare the language, cognitive, and sensory functions of unilateral implant users, bilateral implant users, and their peers with normal hearing, 3) To investigate the relationships between language, cognitive and sensory functions in cochlear implant users. The study included 50 children with cochlear implants and 20 children with normal hearing, aged between 6 and 9 years. The Test of Language Development-Primary (TOLD-P), The Working Memory Scale (WMS), The Rapid Naming Test (RNT), Hearing in Noise Test-Children (HINT-C) and Sensory Processing Measure-Home Form (SPM) were used to assess the language, verbal memory, rapid naming, hearing in noise, and sensory processing abilities of the participants, respectively. It was found that there was no difference between the groups implanted between 12-18 months and 18-24 months in terms of the TOLD-P index scores and levels, WMS levels, RNT level, HINT-C scores, and SPM score, but they performed worse than their peers with normal hearing (p<0,05). It was found that unilateral and bilateral users did not differ in TOLD-P index scores and levels, WMS levels, RNT level and SPM score, but they performed lower than their normal hearing peers (p<0,05). In the HINT-C scores, there was a statistically significant difference between unilateral users, bilateral users and normal hearing groups (p<0,05). In the correlation analyzes, statistically significant correlations were found between TOLD-P index levels, WMS levels, RNT levels and HINT-C scores (p<0,05). The results showed that children with congenital profound hearing loss do not have similar results with their normal hearing peers, even if they are implanted early and use sequentially bilateral cochlear implants.
