Emotion dynamics

The study of how emotional states change over time: how quickly they rise, how long they last, how variable they are and how strongly one moment carries over into the next. Common indicators include intensity, variability, instability and inertia, usually estimated from repeated momentary reports. Differences in these patterns have been associated with well-being and psychological difficulties, although the indicators overlap and their unique contributions are debated.

Where the site uses it

Relief is not resolution: reinforcement, avoidance and memory
Why a restorative experience can leave the underlying difficulty unchanged: negative reinforcement, experiential avoidance, acute mood effects of exercise, rumination and the peak-end rule.
Methods: signals, inference and the limits of detecting a state change
How one could reason about recording a catharsis-like change of state: signals, features, inference and context, baselines, self-report, error costs and ethics, and why every step stays uncertain. Nothing on this site measures anyone.
