Attention: Latency (Time Until First Fixation) for Image |
We defined areas of interest (AOIs) encompassing the image and text portions of each PWL. For each AOI, we examined attention measures of latency (time until the first fixation in the AOI; i.e., how quickly attention is drawn to the AOI), latency duration (length of the first fixation; i.e., how long the AOI is initially viewed), and total fixation time (sum of all fixations in the AOI; i.e., overall viewing allocation, accounting for viewing the same AOI multiple times). Analyses examined the mean of each outcome across the four PWLs within each condition. |

Recall: Participants Ability to Recall Condition Image |
Participants will view 11 warning label images and would be required to identify the warning label images they saw during their eye tracking portion of the session. This outcome measure (Recall -Image) was assessed in a percentage unit of measure. The percentages are not whole numbers for these items because it's the mean % correct for the condition, or the average percent correct across the four images for the group. The results in the Outcome Measure Data table demonstrate the percentage of participants who correctly identified the images from their condition (4 of the 11 images presented to participants were from their randomized condition; A or B). |

Recall: Participants Ability to Recall Condition Text |
Participants will view 11 warning label text statements and would be required to identify the warning label text statements they saw during their eye tracking portion of the session. This outcome measure (Recall -Text) was assessed in a percentage unit of measure. The percentages are not whole numbers for these items because it's the mean % correct for the condition, or the average percent correct across the four images for the group. The results in the Outcome Measure Data table demonstrate the percentage of participants who correctly identified the text statements from their condition (4 of the 11 images presented to participants were from their randomized condition; A or B). |

Knowledge of Smoking Harms |
All participants will select harms caused by tobacco from a list of health issues and diseases, before as well as after viewing the warning labels on the screen. Pre and post warning label exposure knowledge of smoking harms were assessed by using an exploratory scale that asked participants if cigarette smoking caused a list of 18 health conditions with a 5-point response scale, (1=definitely yes 2= probably yes, 3 = might or might not, 4 = probably not, 5 = definitely not). |
