Our research suggests that, in a way, the mere presence of our smartphones is like the sound of our names — they are constantly calling to us, exerting a gravitational pull on our attention. If you have ever felt a “phantom buzz” you inherently know this. Attempts to block or resist this pull takes a toll by impairing our cognitive abilities. In a poignant twist, then, this means that when we are successful at resisting the urge to attend to our smartphones, we may actually be undermining our own cognitive performance.
Are you affected? Most likely. Consider the most recent meeting or lecture you attended: did anyone have their smartphone out on the table? Think about the last time you went to the movies, or went out with friends, read a book, or played a game: was your smartphone close by? In all of these cases, merely having your smartphone present may have impaired your cognitive functioning.
