Subjects identified the left-hand image as a woman and the right-hand one as a man. Yet the two images differ only in skin tone. Study by Richard Russell, Sinha Laboratory for Vision Research, MIT.   Skin color differs by sex: women are fairer and men browner and ruddier. Women also exhibit a greater contrast in... Read More

Great at reading or recognizing faces? You might not do so well on an IQ test.
The English psychologist Charles Spearman was the first to argue that a single factor, called "g," explains most of the variability in human intelligence. When observing the performance of children at school, he noticed that a child who did well in math would also do well in geography or Latin. There seemed to be a... Read More
How to hyperstimulate a sex-recognition algorithm. Women have higher luminous contrast between their facial skin and their lip/eye color. This contrast effect is influenced not only by degree of lightness but also by degree of redness (source). Women are fairer in complexion because their skin has less melanin and less blood (Edwards and Duntley, 1939).... Read More
The inferotemporal cortex is involved in both face perception and color perception. It may be in this region that the brain processes visual data on the hue and luminosity of human skin. If you are a member of the International Society for Human Ethology, you can read my latest article: Hue and luminosity of human... Read More
Averaged face of blue-eyed male subjects (left). Averaged face of brown-eyed male subjects (right). Czech population.

There is now evidence that blue eyes... Read More
Averaged female face (left) and averaged male face (right). The key facial regions for gender recognition, in terms of either response time or accuracy, seem to be where facial skin borders the lips or the eyes. The human face is a special visual object. We do not learn to recognize it. Instead, it is processed... Read More
Postgraduate students, School of Psychology, Cardiff University A recent study from Cardiff University (Wales) has found interesting sex differences in the way men and women evaluate facial skin color, specifically for faces of white, black, or mixed-race origin. The female participants evaluated White faces the least favorably out of all male facial photos. Conversely, the... Read More
Averaged faces of 22 women and 22 men (White American subjects with no makeup). Female faces are lighter-skinned than male faces, while showing more contrast between facial skin and lips/eyes (see research by Richard Russell). Les Presses de l’Université Laval has just published my book Femmes claires, hommes foncés. Les racines oubliées du colorisme. An... Read More
We seem to be born with the ability to recognize the human face. Even infants as young as 1 month old show a consistent, spontaneous preference for face-like stimuli over nonface-like patterns. Such recognition seems guided by an inborn representation of the main facial features, particularly the eyes and the mouth (Pascalis & Kelly, 2008).... Read More
