Volunteers were given tactile alarms ones that vibrated while they had to perform visual tasks. After being given a task with high or low visual load, they had to say whether or not they noticed a vibration in their hands at that moment.
As a result, the researchers found that the perception of vibrations decreased as the amount of visual information received increased.
In other words, the study went far beyond the sense of touch and the reason we close our eyes when kissing: It showed that by deactivating one sense, we end up strengthening other senses.
Does seeing hinder hearing?
In previous studies, researchers had already described that the ability to perceive sound stimuli varies depending on the intensity of the visual information received at the same time.
That's why when we want to pay attention to the lyrics of a song, it's best to close our eyes so that the environment around us remains in the background and we can concentrate on what we're doing to feel that moment. We inhibit the sense of sight in order to improve others.
