Abstract
The authors explored principles of auditory and auditory-visual grouping. Participants made visual temporal order judgments (TOJ) about which of two centrally presented lights appeared first while they heard task-irrelevant critical sounds before the first and after the second light. Temporally misaligned sounds captured the onsets of the lights (i.e., temporal ventriloquism). This temporal ventriloquist effect was greatly attenuated when the critical sounds themselves were flanked by similar sounds, but not when the flanking sounds had different frequency, or rhythm. The results demonstrate that principles of auditory grouping take priority over intersensory ones.
