Influence of colored face masks on judgments of facial attractiveness and gaze patterns.

BACKGROUND

Facial aesthetics are of great importance in social interaction. With the widespread adoption of face masks in response to the Covid-19 pandemic, there is growing interest in understanding how wearing masks might impact perceptions of attractiveness, as they partially or completely conceal facial features that are typically associated with attractiveness.

OBJECTIVES

This study aimed to explore the impact of mask wearing on attractiveness and to investigate whether the color (red or blue) of the mask has any effect on the perception of a person's attractiveness, while also considering gender and age as contributing factors. Additionally, the study intended to evaluate gaze patterns, initial focus, and dwell time in response to masked and unmasked faces.

METHODS

30 AI-generated images of 15 female and 15 male faces were presented to 71 participants (35 male, 36 female) in 3 conditions: not wearing any mask, wearing a red surgical mask, and wearing a blue surgical mask. The perceived attractiveness was rated on an ordinal scale of 1-10 (10 being most attractive). Gaze behavior, dwell time and initial focus were recorded using a stationary eye-tracking system.

RESULTS

The study found that wearing masks had no significant effect on the attractiveness ratings of female faces (p = .084), but it did benefit the perceived attractiveness of male faces which were initially rated lower (p = .16). Gender and age also played a significant role, as both male and female participants rated female stimuli higher than male stimuli (p < .001), and younger participants rated both genders as less attractive than older participants (p < .01). However, there was no significant influence of the mask's color on attractiveness. During the eye-tracking analysis, the periorbital region was of greater interest while masked, with the time to first fixation for the eyes being lower than the non-masked stimulus (p < .001) and showed a longer dwell time (p < .001). The lower face was shown less interest while masked as the time to first fixation was higher (p < .001) and the fixation count was less (p < .001). Mask color did not influence the scan path and there was no difference in revisits to the mask area between red or blue masks (p = .202), nor was there a difference in time to first fixation (p = .660).

CONCLUSIONS

The study findings indicate that there is an interplay between the gender and age of the participant and the facial stimuli. The color red did have an effect on the perception attractiveness, however not in female faces. The results suggest that masks, especially red ones, might be more beneficial for male faces, which were perceived as less attractive without a mask. However, wearing a mask did not significantly impact already attractive faces. The eye-tracking results revealed that the periorbital region attracted more attention and was fixated on more quickly while wearing a mask, indicating the importance of eyes in social interaction and aesthetic perception.
