Primary Outcome Measures

Name	Time	Method
Implicit Positive Smoking Expectancies, Measured by the Implicit Association Test	within 5 minutes post intervention	Scores are measured by recording the amount of time (milliseconds) it takes to categorize smoking-related words with positive (e.g., cool) and negative (e.g., cancer) words. Faster reaction times when categorizing smoking-related words with positive words is evidence of higher positive smoking expectancies.
Amount of Time Spent Looking at Static Smoking Cues in E-cigarette Advertisements	approximately 30 minutes post intervention	Eye-tracking will be used to measure the amount of time (milliseconds) spent looking at static smoking cues in screen shots taken from e-cigarette advertisements. The amount time spent looking at a smoking cue is a measure how much attention was given to the smoking cue. The longer the looking time, the greater amount of attention.
Implicit Positive Vaping Expectancies, Measured by the Implicit Association Test	within 5 minutes post intervention	Scores are measured by recording the amount of time (milliseconds) it takes to categorize vaping-related words with positive (e.g., cool) and negative (e.g., cancer) words. Faster reaction times when categorizing smoking-related words with positive words is evidence of higher positive smoking expectancies.
