Do you know why we kiss with our eyes closed? It used to be thought that people closed their eyes while sharing a kiss because their vision could not focus on something as close as the other person’s face.
But a new study says other. According to Study Human Perception and Performance on vision and tactile sensory experience by cognitive psychologist Sandra Murphy and Polly Dalton at Royal Holloway, University of London, the brain finds it difficult to process other sense if it’s concentrating on visual stimuli. So, by closing our eyes when we kiss, we can more easily focus on other sensations, like touch.
‘By closing our eyes when we kiss, we can more easily focus on other sensations, like touch.’
The study published in the journal of Experimental Psychology did not involve people kissing, suggest that, to on focus on tactile sensation, people might instinctively close their eyes.
Cognitive psychologist found “tactile [sense of touch] awareness depends on the level of perceptual load in concurrent visual task”. However, these conclusion published in journal, were reached without studying couple kissing.
To measure visual sense study participants completed letter searching task of varying difficulty and tactile response was measured by responding to a small vibration applied to one of their hands.
It is important for designers to be aware of these effects, because auditory and tactile alerts are often used in situations of high visual demand, such as driving a car or flying an aircraft.
