The role of cognitive, psycholinguistic, and neurological models in developing, diagnostic and treatment tools for language disorders Naima, Maouchi Sidahmed, Bara Neurolinguistic psychological models Therapeutic program Deaf children Cochlear implant Neurolinguistic psychological model of Chevrie Muller This article aims to explain the role of cognitive, psycholinguistic, and neurolinguistic models that can be adopted as a theoretical basis for constructing diagnostic tools or therapeutic programs for developing oral language for children who have trouble in understanding and producing oral and written language. Based on a carefully selected theoretical background, an integrated treatment protocol was developed for deaf children with cochlear implants. This protocol is based on the neuropsychological linguistic model (MNPL) of Chevry-Muller (2007) to improve language reception and production, respecting all stages, from the initial level to the highest and most complex levels. It is currently undergoing psychometric testing to study its effectiveness and efficacy. 2025-06-12T10:39:46Z 2025-06-12T10:39:46Z 2025 journal article Maouchi Naima, Bara Sidahmed (2025).
