Accepts healthy volunteers: yes
Allocation: NA
Intervention model: SINGLE_GROUP
Intervention model description: All participants will see the same 4 labels (3 sodium labels \[text only, text + icon, and text + pictorial\] and a control bar code label) in a random order.
Primary purpose: PREVENTION

Brief summary: 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.

Detailed description: 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.

Eligibility criteria: Inclusion Criteria:
