This conference paper also builds on the findings of the 2006 Klatzky et al. JEP:A paper. The earlier work showed that spatialized audio descriptions are more robust against increased cognitive load than spatial language. However, where the previous study only showed an advantage for route guidance, this study extended the advantage of spatialized audio to cognitive map development, assessed by a return to origin task. Results from this paper provide continued evidence for the use of 3D audio in nonvisual spatial displays, advantages echoed by Jack Loomis, Bobby Klatzky and their colleagues for more than two decades.
