According to this study, it seems that Caucasoids and Mongoloids don’t examine faces the same way.
Note that this article uses the term “Caucasian” which I assume, based on context, that they are referring to what many people call Caucasoids (to avoid confusion). I.e., roughly the people in Europe, Western Asia, North Africa, and India. (I.e., they are not just referring to people of Caucasia — not just referring to the Georgians, Armenians, Azerbaijani, Ossetians, Kurds, Iranians, Chechens, Abkhaz, Adygei, etc.)
Also, in the article they used the term “Asian”, which I assume should be read as “Mongoloid”. I.e., roughly East Asians.
Caucasians and Asians don’t examine faces in the same way, according to new research. PhD student Caroline Blais, of the Université de Montréal Department of Psychology, has published two studies on the subject: one in Current Biology and the other in PLoS One.
Previous studies have shown that people collect information by mostly studying the eyes as well as the mouth of a face. “The problem is that these studies always used Caucasian test subjects,” says Blais.
Questioning the universality of facial recognition began after studies showed that Asians study faces in an overall fashion, while Caucasians break down faces into distinct parts.

Caucasian and Asian subjects excelled at recognizing someone of their race, yet both had the same level of difficulty in identifying someone of another ethnic group. According to Blais, this says more about the analytical approach of Caucasians and the holistic approach of Asians.In a second experiment, test subjects had to pinpoint an emotion: surprise, fear, disgust or joy. Asians mostly focused on the eyes and not enough on the mouth, which meant some emotions were wrongly identified.
“Asians had particular problems with negative emotions. They confused fear and surprise as well as disgust and anger,” says Blais. “This is because they avoided looking at the mouth which provides a lot of information about these emotions.”
