About this study

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.

Read the 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.

    "Warning: High in sodium." is shown in a black square label on the can of soup.

  • Icon sodium labelBehavioural

    "Warning: High in sodium." is shown beneath a yellow triangle icon with an exclamation mark all in a black square label on the can of soup.

  • Pictorial sodium labelBehavioural

    "Warning: High in sodium." is shown beneath an image of a spilled salt shaker, all in a black square label on the can of soup.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Amount of Time Spent Looking at the Front-of-package Sodium Label (i.e., Dwell Time)

    This outcome will be measured using eye tracking technology.

    Measured: During ~5-minute eye tracking task, as part of a one-time study visit lasting ~30 minutes

Secondary outcomes (6)
  1. Number of Times Looking at the Front-of-package Sodium Label (i.e., Fixation Count)

    This outcome will be measured using eye tracking technology.

    Measured: During ~5-minute eye tracking task, as part of a one-time study visit lasting ~30 minutes

  2. Time to First Fixation on the Front-of-package Sodium Label

    This outcome will be measured using eye tracking technology.

    Measured: During ~5-minute eye tracking task, as part of a one-time study visit lasting ~30 minutes

  3. Dwell Time on "Natural" Claim

    This outcome will be measured using eye tracking technology.

    Measured: During ~5-minute eye tracking task, as part of a one-time study visit lasting ~30 minutes

  4. Self-reported Attention to the Front-of-package Sodium Label

    Assessed with 1 item for each label type. Response options will range from 1 to 5. Higher scores indicate more attention.

    Measured: During ~10 minute online survey, as part of one-time study visit lasting ~30 minutes

  5. Perceived Message Effectiveness of the Front-of-package Sodium Label

    Assessed with 3 items for each label type. Response options will range from 1 to 5. Higher scores indicate greater perceived message effectiveness.

    Measured: During ~10 minute online survey, as part of one-time study visit lasting ~30 minutes

  6. Understandability of Front-of-package Sodium Label

    1 item for each label type. Response options will range from 1 to 5. Higher scores indicate more understandability.

    Measured: During ~10 minute online survey, as part of one-time study visit lasting ~30 minutes
