Nowadays, children with hearing impairment are likely to be exposed to a variety of communicative situations and to use a diversity of communication approaches and strategies for interaction in different environmental contexts. This work package will evaluate how individual language and learning resources (i.e. verbal and non-verbal cognitive abilities, communication strategies) affect spoken and written communication and facilitate daily-life interaction according to the opportunities and constraints of the communicative environment (i.e. multilinguistic and multicultural settings, interactional support within the family). Moreover, researchers will examine how such diverse language skills and communicative repertoires can be assessed.
