Precedence effect in psychology

Audio Location 2023
Geoffrey W Sutton & Bing AI

 The precedence effect is a psychophysical phenomenon identified by Wallach and others in 1949. The effect is the perception of hearing one sound when two sounds were presented one after the other with a short delay. In such cases, the first sound is the lead sound, which determines the localization (localization dominance). The location of the second sound is suppressed (discrimination suppression).

For a  review, see Brown et al. (2015).
