Primary outcomes

  1. Implicit Positive Smoking Expectancies, Measured by the Implicit Association Test

    Time frame: 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.

  2. Amount of Time Spent Looking at Static Smoking Cues in E-cigarette Advertisements

    Time frame: 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.

  3. Implicit Positive Vaping Expectancies, Measured by the Implicit Association Test

    Time frame: 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.
