Race and facial features

Historically, craniofacial genetic research has understandably focused on identifying the causes of craniofacial anomalies and it has only been within the last 10 years, that there has been a drive to detail the biological basis of normal-range facial variation. This initiative has been facilitated by the availability of low-cost hi-resolution three-dimensional systems which have the ability to capture the facial details of thousands of individuals quickly and accurately. Simultaneous advances in genotyping technology have enabled the exploration of genetic influences on facial phenotypes, both in the present day and across human history. There are several important reasons for exploring the genetics of normal-range variation in facial morphology. The facial surface is readily visible and identifiable with a close relationship to the underlying cartilaginous and skeletal structures Stephan et al. Differences in relative size, shape and spatial arrangement vertical, horizontal and depth between the various facial features e.

Predominance of eyes and surface information for face race categorization | Scientific Reports

The proliferation of minority populations in the US workforce has increased the need to investigate differences in facial dimensions among these workers. The objective of this study was to determine the face shape and size differences among race and age groups from the National Institute for Occupational Safety and Health survey of US civilian workers. Measurements of height, weight, neck circumference, and 18 facial dimensions were collected using traditional anthropometric techniques. A multivariate analysis of the data was performed using Principal Component Analysis. An exploratory analysis to determine the effect of different demographic factors had on anthropometric features was assessed via a linear model.

Predominance of eyes and surface information for face race categorization

The own-race bias ORB is a reliable phenomenon across cultural and racial groups where unfamiliar faces from other races are usually remembered more poorly than own-race faces Meissner and Brigham, By adopting a yes—no recognition paradigm, we found that ORB was pronounced across race groups Malaysian—Malay, Malaysian—Chinese, Malaysian—Indian, and Western—Caucasian when faces were presented with only internal features Experiment 1 , implying that growing up in a profoundly multiracial society does not necessarily eliminate ORB. Using a procedure identical to Experiment 1, we observed a significantly greater increment in recognition performance for other-race faces than for own-race faces when the external features e.
