Anatomical Study of Facial Width–to–Height Ratio as a Predictor of Aggressive Behavior among University Students

Anatomical Study of Facial Width–to–Height Ratio as a Predictor of Aggressive Behavior among University Students

CHAPTER ONE

1.1 Background of the Study

Facial morphology has long been associated with personality traits and behavioral tendencies. One anthropometric measure that has attracted attention in recent years is the facial width–to–height ratio (fWHR) (Carré and McCormick, 2008). This ratio is calculated by dividing the bizygomatic width (distance between the cheekbones) by the upper facial height (distance between the upper lip and brow).

Several studies suggest that individuals with a higher fWHR may display greater assertiveness or dominance. Researchers believe that this association could be linked to hormonal influences during development, particularly testosterone. Consequently, fWHR is now studied as a potential marker for behavioral and psychological traits.

However, environmental and cultural factors can influence both facial features and behavioral expression. Therefore, findings from Western populations may not apply universally. Studying this relationship among Nigerian university students will provide valuable insights into how facial structure relates to behavior within a local context.

This research aims to determine whether facial width–to–height ratio can serve as a predictor of aggressive behavior among Nigerian students.

1.2 Statement of the Problem

Most previous studies on facial morphology and behavior have focused on non-African populations. As a result, little is known about how fWHR relates to aggression in Nigerian youths. Without local evidence, it is difficult to draw meaningful conclusions about the relevance of facial structure as a behavioral indicator.

1.3 Aim and Objectives of the Study

The aim of this study is to investigate the relationship between facial width–to–height ratio and aggressive behavior among university students.

The specific objectives are to:

1. Measure the facial width and height of participants using standardized anthropometric techniques.

2. Calculate the facial width–to–height ratio for each subject.

3. Assess aggressive tendencies using validated psychological questionnaires.

4. Analyze the correlation between fWHR and aggression scores.

1.4 Significance of the Study

This study will contribute to the growing field of behavioral anatomy by exploring how physical features may relate to social behavior. The findings will assist psychologists, anatomists, and sociologists in understanding the possible biological basis of aggression. Furthermore, it will add to the body of knowledge on human variation within Nigerian populations.

1.5 Scope of the Study

The study will involve male and female students from selected Nigerian universities aged 18 to 30 years. Participants with facial deformities or a history of psychiatric illness will be excluded.

1.6 Operational Definition of Terms

• Facial Width–to–Height Ratio (fWHR): The ratio between the bizygomatic width and upper facial height.

• Aggression: Behavior characterized by hostility, dominance, or a tendency toward confrontation.

• Anthropometry: The scientific measurement of human body dimensions and proportions.
