Representatives of one ethnic group seem to be “one person” people of other races. The latest research team of scientists from the universities of Stanford and California showed that the inability at first glance to recognize individual racial differences built into the human brain at birth.
In the study, researchers was attended by 17 representatives of the Caucasoid group. The volunteers were shown pictures of people who belonged to the Caucasoid and Negroid races. This was done by magnetic resonance imaging of the brain. Researchers were interested in activity in the visual cortex of the brain, because it is first processed image.
As a result of the experiment revealed that highly sensitive Department of the visual cortex is configured to recognize differences in people only their own race.
The authors emphasize that this innate mechanism is activated at a very early stage of analysis of visual information about the appearance, when the nerve centers are still only decide that for them has meaning and what doesn’t.
According to scientists, is the perception formed in people in the course of evolution. Now, however, it can be the basis of prejudice.
