Abstract
Everyday explanations are interactive processes with the aim to provide a less knowledgeable person with
reasonable information about other people, objects, or events. Because explanations are interactive communicative processes, the
topical structure of an explanation may vary dynamically depending on the immediate feedback of the explainee. In this paper, we
analyse topical transitions in medical explanations organised by different physicians (explainers) related to different forms of
multimodal behaviour of caregivers (explainees) attending an explanation about the procedures of an upcoming surgery of a child.
The analyses reveal that explainees’ multimodal behaviour with gaze shifts (and particularly gaze aversion) can predict a
transition from an elaborated topic to a new one, whereas explainees’ forms of multimodal behaviour with static gaze cannot be
related to changes of the topical structure.
