Abstract

An abrupt change in a visual attribute (size) of apparently moving visual stimuli extends the time the changed stimuli is visible even after its physical termination (visible persistence). In this study, we show that elongation of visible persistence is enhanced by an abrupt change in an attribute (frequency) of the sounds presented along with the size-changed apparently moving visual stimuli. This auditory effect disappears when sounds are not associated with the visual stimuli. These results suggest that auditory attribute change can contribute to the establishment of a new object representation and that object-level audio-visual interactions can occur in motion perception.
