Extension neglect has also been observed in a paradigm in which participants
are exposed for some time to an unpleasant experience. The participants
provide a continuous report of current discomfort, using an ‘affect meter.’ Later
they provide a global judgment of the entire episode. Various experiences have
been studied, including unpleasant films e.g., of an amputation., immersion of the
hand in cold water, exposure to loud noise, and painful medical procedures see
Kahneman, Wakker and Sarin 1997. for a review.. For our purposes, an episode of discomfort can be construed as a set of unpleasant moments. The duration of the
episode is the measure of extension. Valuation by prototype implies that participants
will construct or remember a typical moment of the episode, and evaluate
the episode as a whole by the level of unpleasantness associated with the prototypical
moment}the duration of the episode will be neglected. The hypothesis of
duration neglect has been confirmed in several experiments, with both ratings and
choices as dependent variables
