What this study supports

Supports the claim that a majority chose to repeat the longer trial that ended less painfully, consistent with peak and end effects. A single paradigm of mild physical discomfort.

Who was studied
Participants exposed to a short and a longer cold-water trial and asked which to repeat.
Design
Experiment
Level of evidence
Controlled studies: randomised or experimental designs, and syntheses of correlational work.

Claims that rest on it

Each claim states what the site asserts, at what strength, and with what caveat.

EmpiricalLevel BConfidence HIGH

Retrospective evaluations of experiences are dominated by their most intense and final moments while duration is largely neglected; most participants chose to repeat a longer cold-water trial that ended less painfully.

Scope
Laboratory film clips and cold-water immersion.
Caveat
Applying the rule to remembered nights out is an extrapolation from laboratory episodes.

TheoreticalLevel DConfidence LOW

A short next-day review of what changed after a relieving experience (feeling, understanding, decision, action) is recommended on theoretical grounds and has not been tested as a routine.

Scope
Everyday use by adults without acute clinical needs.
Caveat
Confidence is low because the routine itself has no trial evidence; it rests on theory and laboratory findings about memory.

EmpiricalLevel BConfidence HIGH

Adding a milder but still unpleasant ending to an aversive episode led most participants to choose the longer episode for repetition, and retrospective evaluations of film clips were little affected by their duration.

Scope
Cold-water immersion and film clips in laboratory experiments.
Caveat
The peak–end average in the model is a simplification of a group tendency, and applying it to real-life episodes is an extrapolation.
