This effect, according to the assumption of researchers, is due to the fact that physical changes that occur in the nerves and neurons play an important role in the perception of time with age. Over the years, these structures become more complex and, eventually, begin to collapse, providing greater resistance to the electrical signals they receive. Adults often feel that the experiences of adolescence are much deeper and more significant than the current ones, but in fact they were simply processed by the brain at a higher speed, scientists explain.
According to this hypothesis, the degradation of these key neurological signs leads to a decrease in the rate at which we receive and process new information. For example, it is known that children move their eyes much more often than adults, because they process visual stimuli with greater speed. For older people, this means that fewer incentives are processed at the same time, and this creates the impression that things happen faster.
“The human mind feels that time changes when perceived images change,” said researcher Adrian Bejan. “The present is different from the past, because mental perception changes.” The days seem much longer in adolescence, since the young brain processes more images in one day than the same brain in old age. ”
