Eye-tracking research on sensory and consumer science: A review, pitfalls and future directions

[Display omitted] •Reports of eye-tracking research for sensory and consumer sciences are reviewed.•Bottom-up factors such as visual salience and size influence visual attention.•Top-down factors such as goals and task instructions influence visual attention.•Visual attention affects consumer choice in some cases.•Eye-tracking pitfalls and future studies for consumer science are discussed. Visual processing is a core cognitive element of sensory and consumer science. Consumers visually attend to food types, packaging, label design, advertisements, supermarket shelves, food menus, and other visible information. During the past decade, sensory and consumer science have used eye tracking to elucidate visual processing by consumers. This review paper summarizes earlier findings in terms of bottom-up (i.e., stimulus-driven) processing such as visual salience, size, and top-down (i.e., goal-driven) processing such as goals, task instructions, task complexity, and emotions. Downstream effects of gaze on choice are also reviewed. Pitfalls and future directions of eye-tracking research on sensory and consumer science are also discussed.
