Interaction and common ground in dementia: Communication across linguistic and cultural diversity in a residential dementia care setting

Previous research concerning bilingual people with a dementia disease has mainly focused on the importance of sharing a spoken language with caregivers. While acknowledging this, this article addresses the multidimensional character of communication and interaction. As using spoken language is made difficult as a consequence of the dementia disease, this multidimensionality becomes particularly important. The article is based on a qualitative analysis of ethnographic fieldwork at a dementia care facility. It presents ethnographic examples of different communicative forms, with particular focus on bilingual interactions. Interaction is understood as a collective and collaborative activity. The text finds that a shared spoken language is advantageous, but is not the only source of, nor a guarantee for, creating common ground and understanding. Communicative resources other than spoken language are for example body language, embodiment, artefacts and time. Furthermore, forms of communication are not static but develop, change and are created over time. Ability to communicate is thus not something that one has or has not, but is situationally and collaboratively created. To facilitate this, time and familiarity are central resources, and the results indicate the importance of continuity in interpersonal relations.
