Young people with communication disabilities often experience the loss of their communication competences when they move between contexts. Due to lack of knowledge on this topic, this DFF Research Network aims to bring together international and interdisciplinary experts from Linguistics, Psychology, Sociology, Education Science, and Speech and Language Science. We will draw together and explore the scattered knowledge on communication practices that sustain communicative competences in young people living with communicative disabilities as they move between different institutional and everyday contexts. This entails a special focus on both the use of technologies which the young people often need to participate in interaction with others (e.g. Augmentative and Alternative Communication (AAC) technologies), and, critically, the interactional practices used by the communication partners to recognise, maintain and develop these young people’s communicative competences .
