Summary
Gender significantly influences how people scan faces. Female gazers explore more and focus on the left eye when viewing other females, impacting gaze-based models.
Area of Science:
- Cognitive Science
- Psychology
- Computer Vision
Background:
- Human face perception is crucial for social interaction.
- Individual eye-scanning patterns are stable but influenced by factors like culture and personality.
- Previous studies often used static analyses of limited eye-tracking data.
Purpose of the Study:
- To investigate the temporal dynamics of gaze during face exploration.
- To identify individual characteristics that shape unique gaze patterns.
- To explore information extractable about observers and observed stimuli.
Main Methods:
- Collected the largest eye-tracking dataset to date (405 participants, 58 nationalities).
- Analyzed gaze patterns of participants watching videos of other people.
- Employed novel data-mining techniques to probe temporal gaze dynamics.
Main Results:
- Participant gender (gazer) and actor gender significantly influence face exploration patterns.
- Female gazers exhibit a more exploratory scanning strategy compared to male gazers.
- Female gazers observing female actors show increased attention to the left eye.
Conclusions:
- Gender is a primary determinant of gaze patterns during face observation.
- Distinct gaze strategies exist between genders and based on the observed person's gender.
- Findings have significant implications for gaze-based models in computer vision and clinical psychology.

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Emotional expression encompasses how individuals convey their emotions through verbal communication and non-verbal cues. These non-verbal actions include facial expressions, body language, and physical gestures, such as frowning or smiling. Among these, facial expressions play a crucial role in emotional expression and are understood universally, indicating a biological basis for how humans communicate emotions.

Social-emotional experiences and cultural influences play significant roles in shaping gender development. During middle childhood, from ages 6 to 11, peer groups become dominant in reinforcing gender norms. Children in this age group often align with same-gender peer groups, which actively encourage behaviors that conform to traditional gender roles. For instance, boys may be discouraged from engaging in activities perceived as feminine, reinforcing culturally dictated norms about masculinity...
