The objective of the present study was to explore the perceptual basis of these sexual differences by comparing the visual information used by men and women to discriminate between different intensities of pain facial expressions. Using the data-driven Bubbles method, we were able to corroborate the woman advantage in the discrimination of pain intensities that did not appear to be explained by variations in empathic tendencies. In terms of visual strategies, our results do not indicate any qualitative differences in the facial regions used by men and women. However, they suggest that women rely on larger regions of the face that seems to completely mediate their advantage. This utilization of larger clusters could indicate either that women integrate simultaneously and more efficiently information coming from different areas of the face or that they are more flexible in the utilization of the information present in these clusters. Women would then opt for a more holistic or flexible processing of the facial information, while men would rely on a specific yet rigid integration strategy. © 2022 American Psychological Association},

We found significant associations between body image satisfaction and anti-fat attitudes and sex differences on these measures. We also found a significant interaction effect of the sex of the participants, sex of the VH, and the body size of the VH.
