Humans see the world through the five senses, but how and when the ability to integrate across the senses arises is debated.
Society for Research in Child DevelopmentJul 19 2024 Research shows that humans combine sensory information together, particularly when one sense is not able to produce a sufficient response alone. Studies also show that infants may use multisensory cues to perceive their environments more efficiently.
Results helped researchers confirm that the ability to perceive faces greatly improves between four and 12 months with younger infants benefitting the most from the presence of their mother's odor. The research also suggests that older infants efficiently perceive faces from visual information, and they do not need to rely on other concurrent cues anymore.
The Society for Research in Child Development had the opportunity to discuss these findings with Dr. Arnaud Leleu, Associate Professor of psychology and neuroscience and Head of the Development of Olfactory Communication & Cognition Lab, Center for Taste, Smell and Feeding Sciences at the Université de Bourgogne in Dijon, France. Dr. Leleu: I have a longstanding interest in how sensory perception works in the human brain.
