Summary
Craniofacial bone structure is key for recognizing male faces. For females, body fat negatively impacts sex recognition accuracy, with bone structure alone not fully explaining facial cues.
Area of Science:
- Anthropology
- Forensic Science
- Human Anatomy
Background:
- Previous research identified facial features for sex recognition, influenced by soft tissue and skull bone structure.
- The role of distinct bone structure in facial sex recognition requires further investigation.
Purpose of the Study:
- To investigate the dissociable influences of craniofacial bone structure on facial sex recognition.
- To explore the mediating role of skull morphology in the relationship between facial features and sex identification accuracy.
Main Methods:
- Utilized magnetic resonance (MR) imaging to analyze skull morphology in a large adolescent sample (n=876).
- Employed mediation analysis with bootstrapping to assess the relationship between skull features, facial features, and sex recognition.
- Estimated body fat using bioimpedance analysis.
Main Results:
- Skull features fully mediated the link between facial features and sex judgments in males.
- In females, skull mediation occurred only after accounting for body fat, which negatively impacted accuracy.
- Body fat showed a slight positive influence on male face sex judgments but a robust negative influence on female faces.
Conclusions:
- Craniofacial bone structure is essential for accurate sex judgments of male faces.
- In females, body fat negatively affects sex recognition accuracy, and bone structure alone does not fully explain the observed facial cues.

01:08Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:24Facial Feedback Hypothesis
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 of...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:25Factors Affecting Perception
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
