Researchers have discovered the real reason behind why people close their eyes when they kiss.
According to psychologists from the University of London, people close their eyes when kissing because the brain cannot deal with more than two things at once.
Funny enough, they came to their conclusion without actually looking at a couple kissing. Instead of this, the cognitive psychologists told respondents to undergo a visual test while their response to something touching their hands was measured.
In the research finding published in the Journal of Experimental Psychology: Human Perception and Performance, the team found that visual fields override tactile responses, meaning that it would become difficult to continue kissing if they were looking at something which becomes difficult to process.
One of the researchers explained further that if our eyes were focused on something, it reduces our awareness of stimuli from other senses.
This could also be used to explain why people sometimes close their eyes while learning braille or dancing.
“These results could explain why we close our eyes when we want to focus attention on another sense. Shutting out the visual input leaves more mental resources to focus on other aspects of our experience,” Dr Polly Dalton, one of the researchers, said.
