The phantom notification
Have you ever felt your phone buzz in your pocket, only to check it and find nothing there? It's not just you: in a 2012 study, Michelle Drouin and her team found that up to 90% of the college students surveyed had felt that phantom vibration at some point. The brain, trained to expect a signal, "generates" it even when the phone is on silent, sitting on the table, or even switched off.
Something very similar happens with people: when your attachment system is on alert — for instance, with an anxious attachment style, as Mario Mikulincer and Phillip Shaver have described for decades — your mind constantly scans the environment for signs that someone has pulled away, gotten angry, or is about to leave. And sometimes it finds them where they aren't: a message that takes a while to arrive becomes a silence loaded with meaning, a neutral tone of voice reads as coldness. It's your alarm system, hypervigilant, generating phantom notifications.
This doesn't mean you're "making up" your emotions: the alarm is real, it's just that sometimes the signal that triggers it isn't. Knowing this pattern exists gives you a useful question to ask before reacting: "is what I'm noticing a real signal, or is my system just checking the phone just in case?". You won't always know right away, but simply asking the question already turns the alarm's volume down a little.
Next time you feel an alarm signal in a relationship, before reacting ask yourself: is this a real signal, or my system checking the phone just in case?
