Self-referential Processing
A brain function (DMN) for spontaneously thinking about oneself, remembering the past, and imagining the future, active during mind-wandering and rest.

Self-referential processing is a neural function mediated by the default mode network (DMN) that involves spontaneously thinking about oneself, autobiographical memory, and future self-projections. It is distinct from focused external attention and supports mind-wandering, social cognition, and temporal navigation.
What this means in real life
When reading a news story about someone losing their job, you instinctively think about your own job security and worry, rather than simply absorbing the facts. This personal connection makes the story stick in your memory far longer.
What it isn’t
It is not narcissism or self-centeredness. Self-referential processing is an automatic cognitive mechanism everyone uses; narcissism is a personality trait involving excessive self-focus and lack of empathy. The process itself is neutral and universal.
Commonly misused online
Social media often conflates it with 'making everything about yourself'—treating normal self-reference as selfish behavior. In reality, relating new information to your own life is how humans learn and remember; the problem arises only when it prevents listening to others.
