- Eyebrow movements, especially furrows, signal problems during face-to-face conversations.
- Furrows are strongly associated with restricted clarification requests.
- Furrowed brows prompt longer responses from participants in virtual reality experiments.
- Furrows alone may initiate repair during conversation.
- Presence or timing of eyebrow movements did not significantly affect repair latency.
- Individual differences in empathy and fear of negative evaluation did not significantly modulate the effects.
