Abstract

Facial dimensions have been shown over the years to correlate with human behavior. However, little is known regarding this correlation among African population, particularly Nigerians. This study aimed to determine the relationship between facial dimensions and different self-reported forms of aggression (physical, verbal, anger, and hostility) among Nigerians. A total of 400 undergraduate students (200 male and 200 female) aged between 16 to 30 years old were randomly selected. A 2D facial images were used to measure facial dimensions (n-sn, sn-gn, go-go and zy-gy) and five facial ratios: upper facial weight/lower facial height (UFW/LFH), upper facial weight/lower facial weight (UFW/LFW), upper facial weight/upper facial height (UFWUFH), upper facial height/facial height (UFH/FH) and fWHR-lower derived from the measured linear dimensions using a Sony digital camera and art face 3 software. Buss and Perry aggression questionnaire was adopted, scores for each aggression scale was recorded. Data analysis was made using IBM SPSS software version 22 and the Cronbach’s alpha for each scale was above 0.70. Pearson’s correlation analysis was used to determine the relationship of facial biometrics with aggressive tendencies. It was observed that lower facial height (sn-gn) significantly correlates with verbal aggression and anger. Facial height (FH) also correlates with verbal aggression in both sexes, and facial weight to height ratio (fWHR) also correlates significantly with anger (AN). Lower facial height to facial height ratio (LFH/FH) also correlates significantly with verbal aggression (VA) and anger (AN) in respective of sex but correlates with same in male only. Similarly, upper facial width to lower facial height (UFW/LFH) correlates significantly with verbal aggression and anger irrespective of sex and with anger only in males.

In conclusion, facial characteristics are to some extent indicators of one’s mood.
