According to University of Missouri researchers, some people experience anxiety and various physical systems when they fail to carry their mobiles with them. A short article about this 21st century malady can be found in the Huffington Post. The actual study—”The Extended iSelf: The Impact of iPhone Separation on Cognition, Emotion, and Physiology”—appears in the Journal of Computer-Mediated Communication.

Those who prefer getting their psychological science as a film may enjoy “Login,” an iPhone short by Bralizian director Cristiano Sousa. In the dramedy,  the protagonist lives with his smartphone 24 hours per day damaging his social intercourse and his own life.

Students of film–as opposed to psychology–may wish to note how many locations Sousa crowds into less than two-and-a-half minutes.

“Login” is showcased in the current Super9 Mobile Film Fest.
