When searching for a computer file, a person uses the same part of the brain as a dog looking for a bone.

Psychologists at the University of Sheffield have found that when searching for computer files, a person acts like a dog looking for a bone.

Alas, the search methods in 95% of the people inhabiting the Earth have not changed over the past several million years. Scientists were convinced of this using data obtained from a brain scan. So when working with IT-information, most of us use the so-called "hierarchical navigation" - viewing the list from top to bottom. Much fewer computer owners use the keyword search method.

Dr. Yael Ben, from the University's Department of Psychology, noted that despite advances in search technology, computer users prefer to find files using folder navigation rather than more flexible and modern query methods.

Scientists have found that in the process of navigating through folders, a person uses the same areas of the brain as during normal navigation. They are located in the back, which turns on, in particular, when a person makes his way home from work. The brain of a dog buries in a bone in order to find it later.

When searching with a keyword, the frontal region of the brain is activated, which is closely associated with linguistic processing. This opportunity is unique to humans.
