It’s free, every week, in your inbox.
There is also evidence of combinations of emoji being deployed.

Aroundtwo-thirdsof the brains neural activity relates to vision (when our eyes are open).

Around 40% of the brains nerve fibers are connected to the retina.
And it takes an adult human just 100 milliseconds to recognize an object.

But creative communicative smarts can often find novel ways of conveying important ideas in the service of digital communication.
And this is as true when communicating using emoji in the COVID-19 pandemic as at any other time.

For instance, the rolling eyes emoji ?
often signals that the meaning of a message is the opposite of what the words actually say.
For instance, a wink ?
