The main questions it aims to answer are: Do children with CIs use more mental energy to listen than children with normal hearing, and does this extra effort slow their brain development over time? Does listening with two ears (bilateral CIs or a CI plus a hearing aid) reduce listening effort compared to listening with one ear only? How does listening effort affect children's ability to get along with others and adapt to daily life? Researchers will compare children with CIs to children with normal hearing to see if differences in listening effort lead to differences in cognitive development, socia
