From learning a language to riding a bike, most of our experiences are multisensory in nature. The fact that the brain can integrate information from different sensory modalities (hearing, vision, etc.) into a coherent and unitary experience is truly amazing given that each sensory modality simultaneously receives qualitatively different types of input (e.g., photons, molecules, pressure, etc.) and this information is processed, at least in the early stages of processing, by dedicated sensory systems. My program of research examines how infants, children, young adults, and older adults process and integrate multisensory information and how this ability sub-serves various cognitive tasks such as statistical learning, categorization, word learning, and individuation.
