Brief Positive-Affect Lift
A brief mood lift produced by an AI exchange that raises a user's momentary positive affect without causing distraction or exaggerated elation, leaving task focus intact.
Operational Definition
EVENT. One occurrence is coded when a short within-session rise in self-reported or observably expressed positive affect follows a specific AI turn, and the following turns show no drop in on-task behavior. The affect-rise tied to that turn is the countable marker.
Measurement Schema
Proposed measurement protocol (not yet empirically validated): Momentary affect probe: single-item positive-affect rating (0-100 visual analog scale) sampled immediately before and after the triggering exchange; the pre-post difference indexes the lift; aggregated as mean within-person change with a paired test, paired with a task-focus check (on-task action present in the next turn).
