Brief summary: The goal of this study is to determine the effectiveness of pictorial warning labels (PWLs) featuring narrative (vs. non-narrative) content in communicating the cancer risk of alcohol. Participants will be randomized to view either three narrative or non-narrative PWLs. Key outcome variables include visual attention, message reactance, risk perceptions, and intentions to reduce and stop drinking.

Detailed description: The goal of this study is to determine the effectiveness of pictorial warning labels (PWLs) featuring narrative (vs. non-narrative) content in communicating the cancer risk of alcohol. Participants will be recruited from online panels. Participants will first be invited to participate in an online screening survey. Eligible participants will be invited to participate in the main experiment. In the main experiment, participants will first answer questions concerning baseline alcohol consumption and other background information. Then they will engage with a webcam-based eye-tracking task through Sticky by Tobii. Participants will first read instructions and tips related to completing the eye-tracking task. They will complete a brief calibration procedure and be presented with either three narrative PWLs or three non-narrative PWLs. Sticky by Tobii will record participants' gaze, thereby measuring visual attention to each PWL. After viewing each PWL, participants will answer a few questions. After viewing all three PWLs, they will answer questions based on all images combined. Upon study completion, participants will be compensated. A follow-up survey will be sent to participants after two weeks, which includes questions about their drinking behaviors, information seeking behaviors, and social interactions.

Eligibility criteria: Inclusion Criteria:

1. be at least 21 years old;
2. have consumed more than three alcoholic drinks per week over the past year;
3. be willing to participate in remote eye tracking tasks and have necessary technical support to complete remote eye tracking tasks (i.e., having access to high-speed Internet and a computer/tablet/phone equipped with a high-speed camera).

Exclusion Criteria:

1. be younger than 21 years old;
2. has not consumed more than three alcoholic drinks per week over the past year;
3. be not willing to participate in remote eye tracking tasks and have no necessary technical support to complete remote eye tracking tasks (i.e., having access to high-speed Internet and a computer/tablet/phone equipped with a high-speed camera).
