The document discusses the phenomenon of "phubbing", which refers to ignoring others in social situations due to focus on one's mobile phone. It traces the origin of the term to 2012 when an advertising agency coined it. Effects of phubbing include poor communication quality and relationship dissatisfaction. Phubbing can be especially problematic in classrooms, where it hinders learning, and in clinical settings, where it can compromise patient care and confidentiality. The document examines scales to measure phubbing behavior and provides tips for individuals to reduce phubbing, such as modeling phone-free interactions and implementing "digital detox" periods.
