We Have A 'Force Field' Around Our Bodies And Here's How You Can Feel It

You know what your personal space is. Uninvited strangers invading it invoke an immediate sense of unease. A bird flying over but too close to your head may cause you to reflexively duck. It’s like we don’t just end where our bodies end, but a little bit beyond.

In a new study published in the journal Cognition on June 24, neuroscientists at the Karolinska Institute in Stockholm describe how they did this using an altered version of the so-called rubber hand illusion.
