Multisensory enhancement of localization under conditions of induced myopia.

W David Hairston, Paul J Laurienti, Gautam Mishra, Jonathan H Burdette, Mark T Wallace,

Enhanced behavioral performance mediated by multisensory stimuli has been shown using a variety of measures, including response times, orientation behaviors, and even simple stimulus detection. However, there has been little evidence for a multisensory-mediated improvement in stimulus localization. We suggest that this lack of effect may be a result of ... Read more >>
