Abstract: | Repetition blindness (RB; Kanwisher, 1987) is the term used to describe people’s failure to detect or report an item that
is repeated in a rapid serial visual presentation (RSVP) stream. Although RB is, by definition, a visual deficit, whether
it is affected by an auditory signal remains unknown. In the present study, we added two sounds before, simultaneous with, or after the onset of the two critical visual items during RSVP to examine the effect of sound on RB. The results show that the addition
of the sounds effectively reduced RB when they appeared at, or around, the critical items. These results indicate that it
is easier to perceive an event containing multisensory information than unisensory ones. Possible mechanisms of how visual
and auditory information interact are discussed. |
