Cognitive performance in deaf children using cochlear implants

Abstract Background: Cognitive abilities like language, memory, reasoning, visualization, and perceptual functioning shape human action and are considered critical to the successful interaction with the environment. Alternatively, hearing loss can disrupt a child's ability to communicate, and negatively impact cognitive development. Cochlear implants (CI) restore auditory input thereby supporting communication and may enhance cognitive performance. This study compares general cognitive development after cochlear implantation (2017-2019) in two groups of Jordanian children implanted earlier (age:4-6 years, N = 22) and later (7-9 years, N = 16) to the development of randomly selected normal hearing peers (N = 48).
