“…They found that facilitator behaviours with positive influence were continuous feedback and acknowledgement of the contributions of the participants, explicating conversation rules, standards or guidelines, promoting interactional symmetry, directing attention towards joint efforts to find lost words, using humour for different purposes, and communicating multi-modally through both verbal and visual expressions (for instance, spoken words, written keywords, gestures and pictures). Behaviours found to have negative impact included asking plenty of recycled questions (that is, approximately, repeated questions without connection to previous participants' contributions), a lot of closed questions with predetermined answer alternatives, test questions (following the IRE pattern) that signal power asymmetry, and exposing errors of the participants [37]. In line with several of these results, Lanyon, Worrall, and Rose [36] found that persons with aphasia themselves underlined the importance of promoting non-hierarchical interactions and equal opportunities for participation in conversation groups, where the "democratic feel" (p. 528) of the conversation is present and the responsibilities for the group process are distributed among the participants.…”
