It is customary to consider sound as being the province of auditory perception alone. However, recent findings and theory have emphasized the interactive nature of the sensory modalities as well as the ways in which sensory processing underlies higher cognition. For example, multisensory processing, in which multiple senses (vision, audition, touch) are used in concert, is beginning to be regarded as the norm, not the exception to perception. Furthermore, “embodied cognition” theories, that stress the close coupling of brain, body, and sensory systems, emphasize the importance of understanding how the dynamics of modality-specific constraints affect higher level cognition such as learning and memory. To put it another way: because the brain is an integrated functional system, sensory processing (and, by extension, the effects of sensory deprivation) are not completely independent from the rest of neurocognition and thus may have secondary effects on the brain and cognition as a whole.
