A use of attention
Why do we ruminate?
We ruminate because it can feel like the only way to settle an unanswered question, and because it can postpone feeling. Both payoffs teach the next loop. Rumination is a process with a substantial evidence base as a maintaining factor for low mood. It is not a diagnosis and not the same as concrete reflection.

Definition
Repetitive, passive focus on distress and its meanings, often past-oriented, without moving into a next step.
Nolen-Hoeksema’s longitudinal work found that a ruminative response style predicted later distress. That supports rumination as a maintaining process. It does not establish a single neural mechanism, and it is self-report research with those limits.
In simple terms
You keep turning the same painful story because stopping feels like leaving it unsolved — or like having to feel it. The turning is practice.
Scientific explanation
Attention plus working memory occupancy plus negative reinforcement (avoided affect). Sleep and stress make the loop cheaper.
Psychology perspective
Concrete, time-bounded problem-solving is a different use of the same machinery.
Neuroscience perspective
Do not invent a rumination nucleus. Control and affect networks are the honest level of talk.
What research shows
Ruminative style predicted later distress in community adults (moderate evidence, self-report).
What the research does not prove
That all thinking about pain is rumination, or that you have depression because you replayed a conversation.
What remains uncertain
Causal neural pathways; cultural differences in what counts as useful reflection.
Practical implications
If you can name a next physical step, it may be problem-solving. If you cannot, time-box and get off the mental wheel. Impairing low mood deserves clinical care.
Educational only — not a diagnosis, not a treatment plan, not a crisis service.

Questions
Is all thinking about a problem rumination?
No. Concrete, time-bounded problem-solving is a different use of the same machinery.
Can rumination become a habit?
Yes, in the ordinary learning sense: a context (night, bed, a song) cues the same replay because it has paid off as a feeling of doing something.
