The HEARING category includes articles associated with the processes of audition. Some articles may also be categorized under other headings. For example, an article on ventriloquism might be listed under both Hearing and Seeing, because ventriloquism involves both. In particular, ventriloquism can be loosely described as a phenomenon in which one's visual percept of position affects the place from which a sound seems to originate, despite contradictory information from your ears. As one can easily appreciate, articles under Hearing that consider our perceptions of sounds or of auditory space might also be categorized under Perceiving.
