The goal of this study is to examine attention elicited by icon, text-only, and control front-of-package food labels. The study also aims to explore whether English language proficiency moderates the impact of icon vs. text-only labels on attention.
In this study, participants will attend one in-person visit, lasting approximately 15 minutes after signing informed consent. First participants will complete an eye tracking task where their attention to study stimuli is measured objectively via an eye tracker (i.e., eye tracking task). The eye tracking task will take \~5 minutes. Then, participants will complete a brief \~10 minute self-administered survey on a computer.
