RT food/non-food: mean reaction time (in ms) in food-relevant/non-food-relevant trials in visual probe task. RT bias: difference reaction time (in ms) in food-related and non-food-related trials. Gaze direction food/non-food: the average number of trials when the first fixation was directed to the food image across all trials. Gaze direction bias: the proportion of the number of trials in which the first fixation was directed to a food image out of the number of all trials in which the fixation was directed toward either the food or non-food image. Gaze duration food/non-food: the average time spent gazing at food/non-food (in ms) per trial. Gaze duration bias: the average proportion of gaze duration toward a food image out of the average total gaze duration toward all images (food and non-food).
