The successful navigation of complex everyday environments with multiple sensory inputs—such as restaurants, busy streets, and other social settings—relies on the brain’s ability to organize the barrage of information into discrete perceptual objects on which cognitive processes, such as selective attention, can act.

Several factors appear to contribute to SPiN abilities in adults with typical hearing, including the top-down cognitive functions of attention, working memory, and inhibition.
