Momentary Reports

Pain in Real Time
Continuous Experience
Patients report pain minute by minute during invasive procedures.
Unequal Profiles
Intensity fluctuates and duration differs widely.
Peak-End Memory

The Stored Episode
Selective Weight
The worst moment and the final moment dominate retrospective ratings.
Duration Neglect
Longer procedures are not remembered as proportionally worse.
Gentle Ending

Relief as Evidence
Slight Improvement
A longer exposure ends with warmer water and reduced pain.
Better Memory
The improvement makes the objectively worse episode seem preferable.
Repeated Suffering

The Choice to Repeat
Memory's Verdict
Most participants choose the longer exposure when its ending is better.
Mistaken Preference
The remembering self overrides the experiencing self.
Medical Design

Designing Better Endings
Memory Objective
A physician seeking better memories may lower peaks and soften endings.
Welfare Conflict
Those choices may increase total pain rather than reduce it.
