Neuroscientists discover adaptation mechanisms of the brain when perceiving letters of the alphabet
The headlights – two eyes, the radiator cowling – a smiling mouth: This is how our brain sometimes creates a face out of a car front. The same happens with other objects: in house facades, trees or stones – a “human face” can often be detected as well. Prof. Dr. Gyula Kovács from Friedrich Schiller University Jena (Germany) knows the reason why. “Faces are of tremendous importance for human beings,” the neuroscientist explains. That’s why in the course of the evolution our visual perception has specialized in the recognition of faces in particular. “This sometimes even goes as far as us recognizing faces when there are none at all.”
Until now the researchers assumed that this phenomenon is an exception that can only be applied to faces. But, as Prof. Kovács and his colleague Mareike Grotheer were able to point out in a new study: these distinct adaptation mechanisms are not only restricted to the perception of faces. In the The Journal of Neuroscience the Jena researchers have proved that the effect can also occur in the perception of letters.
