We’re not sure how to feel about this. Experts say emoticons have become such an important part of the way we communicate that we now react to them in the same way as we do human faces.
Research suggests our brains have developed to read emotional cues in happy and sad emoticons just like we do during face-to-face interactions. There’s one catch- using brain scans, the study found that we only react to emoticons that are typed in a left-to-right format, not when they’re flipped in the other direction.
Something to keep in mind the next time you write a text message.
