At the moment of kissing it is a universal reflex that we all, we close our eyes. But why do we all have this automatism? According to a study published in the Journal of Experimental Psychology: Human Perception and Performance, the origin of the closure of our eyelids would be due to the fact that a visual task reduces the sensitivity to stimuli of other senses.
Man is single task
The human being is a single task, which is what this London study tends to show us. To arrive at this conclusion, the participants were subjected to visual tests and it is evident that their tactile sensitivity was less important when they had their eyes open.
“Stopping the visual leaves more mental resources to focus on other aspects”
Our brain has this ability to diminish one sense in order to prioritize another, for example we know that when we are focused on visual task, hearing is diminished.
A matter of concentration
So, if we close our eyes it’s to enjoy 100% of the sensations that a kiss provides, putting aside the vision leaves more mental resources to focus on other aspects of our experience.
