Is there anything more annoying than trying to have a conversation with someone while they are sending text messages? Well it turns out, it’s not (entirely) their fault for ignoring you.
A new study from University College London found when people text, they actually go temporarily deaf! The researchers found that when we focus on something visual like texting or playing a video game, our brains temporarily tune out normal sounds. So you’d hear something unusual, like a siren, but you don’t hear normal stuff, like people talking. The reason is because our hearing and vision basically split the same resources in the brain, so when we’re focused on one, it’s tough to use the other.
