noun The function of hatching asynchrony has been the subject of dynamic debates and intensive research effort. Example sentencesExamples - Specifically, participants are presented with a sequence of brief stimuli with a constant stimulus onset asynchrony, and are asked to respond when they believe the sequence has ended.
