Multisensory experiences crucially contribute to the development of infants' ability to match audio-visual (A-V) information. This study investigated two-day-old newborns' ability to bind non-verbal, naturally occurring, experienced A-V stimuli. Our results demonstrate that, when presented with experienced stimuli (yawns and hiccups) within an intermodal matching procedure, 2-days-old newborns matched not only synchronous (Experiment 1) but also asynchronous A-V information (Experiment 2). Conversely, no evidence of A-V association was found when unexperienced stimuli, such as a linguistic sound (syllable/ba/) (Experiment 3), were presented in asynchrony. The possible role of sensorimotor experience in the early emergence of intersensory abilities is discussed.

Abstract
Multisensory experiences crucially contribute to the development of infants' ability to match audio-visual (A-V) information. This study investigated two-day-old newborns' ability to bind non-verbal, naturally occurring, experienced A-V stimuli. Our results demonstrate that, when presented with experienced stimuli (yawns and hiccups) within an intermodal matching procedure, 2-days-old newborns matched not only synchronous (Experiment 1) but also asynchronous A-V information (Experiment 2). Conversely, no evidence of A-V association was found when unexperienced stimuli, such as a linguistic sound (syllable/ba/) (Experiment 3), were presented in asynchrony. The possible role of sensorimotor experience in the early emergence of intersensory abilities is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
