Songbirds tracking territorial calls lose memory of previous songs when a new call arrives—working memory treats sequential sounds as updates, not additions. This is adaptive stream processing: when information arrives in temporal sequence, later signals likely replace rather than supplement earlier ones. For meetings: 'Any questions?' after presenting data overwrites the data in auditory memory, which is why effective facilitators pause before asking.
