If you find yourself compulsively checking Facebook, Snapchat or Twitter many times a day, especially when carrying out other important tasks such as driving, on a phone call, in a work meeting or when you are pretending to listen to your significant other, it may be because you have an imbalance between two systems within your brain.
Neuroscientists theorise a dual system at work in the brain when we make decisions: one that automatically and often subconsciously responds through habit to triggers such as a Facebook message alert; and the one that makes rational decisions based on reasoning and weighing up options.
A stronger tendency towards the former system results in poor impulse control, which is bad news for smartphone users who have a multitude of distractions at their fingertips.
"The clear and strong effect of problematic social media use on an academic performance was astounding. A slight increase in problematic social media use translates into significant grade loss, and this declined performance is persistent – it remained one year after our initial study," says Ofir Turel, a California State University professor whose research has found a link between problematic social media use and this kind of brain imbalance.
