If you find yourself reaching to answer your phone only to find that it never rang, you could be suffering from "ringxiety", according to academics. Psychologists believe people who are insecure about their friendships or crave company even may start to hear phantom ringtones, notifications or the vibration of nonexistent messages."Mobilephone users have reported experiencing ringing and/or vibrations associated with incoming calls and messages, only to find that no call or message had actually registered," said Daniel Kruger of the University of MichiganKruger and Jaikob Djerf compared the frequency of "phantom ringing" among 411 volunteers who had reported levels of attachment anxiety.Eight in 10 said they had experienced phantom vibrations and almost half said they had heard ringing.Individuals who scored high in attachment anxiety were 18% more likely to experience phantom ringing and notifications."Phantom ringing and phantom notifications in one sample were significantly predicted by high levels of attachment anxiety," Kruger said.The study was published in the journal Cyberpsychology , Behaviour and Social Networking.Editor-in-chief Brenda Wiederhold said: "There's a growing awareness that ringxiety may result in both immediate and longer-term negative health effects, including headache, stress and sleep disturbances." ..
