Although humans are almost constantly exposed to stimuli from multiple sensory modalities during daily life, the processes by which we learn to integrate information from multiple senses to acquire knowledge of multisensory objects are not well understood. Here, we present results of a novel audio – visual statistical learning procedure where participants are passively exposed to a rapid serial presentation of arbitrary audio – visual pairings (comprised of artificial/synthetic audio and visual stimuli). Following this exposure, participants were tested with a two-interval forced-choice procedure in which their degree of familiarity with the experienced audio – visual pairings was evaluated against novel audio – visual combinations drawn from the same stimulus set. Our results show that subjects acquire knowledge of visual – visual, audio – audio, and audio – visual stimulus associations and that the learning of these types of associations occurs in an independent manner.
