Backchannels in the lab and in the wild
Backchannel choices affect conversational development. Some backchannels invite interlocutors to continue to the next part
of what they are saying and others invite them to elaborate on what they have just said. We tested how communicative modality (audiovisual,
audio, text), environmental setting (wholly in-lab, partially in the wild), and conversational goals (on-task, off-task) influenced
backchannel usage by participants. We found that backchannel production depends on modality, setting, and goals. For example, we found that
specific backchannels played a more prominent role in self-motivated dialogue. Knowledge of how backchannels are used has both theoretical
and practical implications.
