Visual Attention in Real‐World Conversation: Gaze Patterns Are Modulated by Communication and Group Size

Abstract

Gaze behavior both initiates and maintains conversations, playing a crucial role in real‐world collaboration. Hitherto, most findings on social attention stem from research using pictures of faces in the laboratory, however, attention operates differently in the real world. Thus, we know little of how gaze behavior operates in naturalistic interactions. To bridge this gap, we applied mobile eye‐tracking to investigate the gaze patterns present in naturalistic conversations. Specifically, we examined gaze behavior of participants in a group of two or five, either sitting together in silence, or engaging in a conversation, in which they took turns either listening or speaking to each other. Results show that participants looked more frequently towards others when the group was communicating compared to when remaining silent, and that they looked at others more frequently when listening compared to when speaking. Furthermore, being part of a dyad led to more social attention being afforded during conversation compared to the group situation, regardless of whether subjects were listening or speaking. Meanwhile, when sitting in silence subjects showed less social gazing in a dyad than in a group of five. Our results provide qualitative and quantitative insights into the patterns of visual attention during dynamic naturalistic conversations.
