Auditory spatial attention is a specific form of attention, involving the focusing of auditory perception to a location in space. Although the properties of visuospatial attention have been the subject of detailed study, relatively less work has been done to elucidate the mechanisms of audiospatial attention. Spence and Driver note that while early researchers investigating auditory spatial attention failed to find the types of effects seen in other modalities such as vision, these null effects may be due to the adaptation of visual paradigms to the auditory domain, which has decreased spatial acuity.
