Abstract
Personalisation is the new mantra in social care; this article focuses on how personalisation can be achieved in practice, by presenting an analysis of data from people with learning disabilities and their personal assistants, where traditional care relationships have often been shown to be disempowering. The focus here is on the ways in which both parties use references to shared knowledge, joint experiences or personal-life information. These strategies can be used for various social goals, and instances are given where shared references are used during non task-related talk. Both parties are seen on occasion to attempt to refer to shared information, and dense layers of inference can result, which move the interaction onto an ordinary, more symmetrical and friendly footing. The article concludes that shared knowledge referencing creates a way to shift between the personal and the professional, to blur the boundaries, and to create a new and more personalised relationship.
