jats:titleAbstract</jats:title>jats:pMobile eye-tracking was used to investigate the link between teacher gaze and student-rated teacher interpersonal behaviour. Teacher gaze was recorded for 10 min during a teacher-centred part of a naturally occurring lesson. The jats:italicQuestionnaire on Teacher Interaction</jats:italic> was then administered to assess how UK students evaluated their teacher interpersonally in that lesson. Teachers conveyed greater dominance (or interpersonal agency) through increasing eye contact while asking questions (‘attentional gaze’). Teachers conveyed more interpersonal friendliness (or communion) through increasing eye contact while lecturing (‘communicative gaze’). Culture did not affect the way gaze was associated with students’ interpersonal perceptions.</jats:p>
