Scientists at Johns Hopkins University in the US found that people are not able to recognize truth through the senses and objectively look at things. Experts came to such conclusion on the basis of a series of “philosophical” experiments with two coins. The results were published in the journal Proceedings of the National Academy of Sciences, briefly about the study reported in a press release on MedicalXpress.
During the experiments, volunteers were shown two coins, one of which was oval and the other round. The subjects were asked to choose an oval coin, but since the round coin was at an angle to the line of sight, it also seemed oval. The illusion was maintained, if the coins were fixed, moved or was depicted on the computer screen.
Scientists expected that the knowledge that one of the coins round, will give the subject the ability to quickly and correctly perform a test, but it was for the subjects challenging. According to the researchers, it demonstrates how stereotypes can distort people’s perceptions.
When a person sees any object, the brain identificeret it, by combining the processing of new visual information with existing ideas about the world and assumptions. If you take a circular coin and look at it at an angle, the brain still recognizes the circle. The same principle works when people recognize the real color of the object under different lighting conditions. However, until now remained unclear whether the brain really understand whether something is round, if it looks oval.
In the future, the researchers have planned other experiments, combining philosophical ideas with the neurobiology of human perception.
