Descriptive results of eye tracking during the free-viewing task.
| Stimuli | Smokers (n = 34) | Non-smokers (n = 37) | |||
|---|---|---|---|---|---|
| M | SD | M | SD | ||
| Fixation count | Smoke | 116.21 | 44.96 | 108.19 | 39.04 |
| Neutral | 89.79 | 35.88 | 93.00 | 37.95 | |
| Mean fixation time (ms) | Smoke | 130 | 41 | 113 | 42 |
| Neutral | 107 | 34 | 110 | 36 | |
| Initial fixation time (s) | Smoke | 4.36 | 2.70 | 5.48 | 3.10 |
| Neutral | 5.41 | 2.17 | 5.31 | 2.98 | |
| Proportion smoke-related first fixation (%) | 59.31 | 17.98 | 46.40 | 23.94 | |
| Dwell time (s) | Smoke | 78.15 | 12.70 | 76.43 | 15.31 |
| Neutral | 67.62 | 12.16 | 68.21 | 12.38 | |
Means (M) and standard deviations (SD) as well as number of participants (n) are given for smokers and non-smokers. Fixation counts are unitless absolute numbers, milliseconds are indicated for mean fixation time, seconds are indicated for the remaining time variables, and percentages are given for the proportion of trials in which first fixations were smoke-related.
