The Peak and End rule describes the effect that retrospective evaluations of temporal events significantly depend on the most extreme affect (peak) experienced during an episode and on the affect at the ending. Other features, like the duration of an event, seem to be widely negligible. We are testing this hypothesis in the context of soundscape evaluation in a series of listening tests conducted in Montréal, Canada, and Duesseldorf, Germany. The soundscapes consisted of recordings of different locations (e.g., railway station, park) and were edited so that there was one presumed emotional “peak moment.” The task of the test group was to indicate momentary judgments by continuously adjusting a slider on a computer interface over the course of the stimulus presentation. Additionally, the participants had to make an overall retrospective rating of the soundscapes after listening to them. To investigate attention effects in the course of the test task a second group was asked to only judge the sounds retrospectively. Preliminary results indicate that the Peak and End rule in combination with the averaged momentary evaluations well predict the retrospective judgments. Within this contribution the results of the experiment will be presented and implications for soundscape design will be discussed.
