The TAYACI project consists of five sub-projects studying long-term effect of cochlear implants on 1) lingustic and cognitive development 2) hearing 3) balance 4) relationship with etiology 5) mental health.The current study is part of sub-project 1 studying the participants' linguistic and cognitive development, focusing on executive functions. Selection method:All potential participants who met inclusion criteria were invited by mail.The inclusion criteria were: First cochlear implant before 30 months of age, 12-22 years old, following normal curriculum and have at least one parent who speaks Swedish.Test procedure: Invited participants who consented completed language tasks and questionnaires (self- and parental assessment) at one study occasion. Medical record data were obtained on hearing background.Time period examined:march 2022 – october 2023Geographical location: Sweden (various regions).Number of individuals:70Population: 43 participants who received cochlear implants before the age of 30 months, are 12-22 years old and follow normal curriculum. All recruited via Karolinska University Hospital.27 participants with typical hearing, 12-22 years old and following normal curriculum. Recruited through advertisements, through contact with schools and through convenience selection.Study design:Cross-sectional studyCohort studyResponse rate/participation rate:Missing data for cochlear implant group: BNT (n = 2), PPVT-4 (n = 4), Reading span task (n = 7), Serial Recall of Nonword (n = 1), Repetition of Nonword (n = 1), CC(C)T, (n = 7).
