TAILIEUCHUNG - Endogenous orientation of visual attention in auditory space

Visuospatial attention is asymmetrically distributed with a leftward bias (. pseudoneglect), while evidence for asymmetries in auditory spatial attention is still controversial. In the present study, we investigated putative asymmetries in the distribution of auditory spatial attention and the influence that visual information might have on its deployment. A modified version of the Posner task (. the visuo-audio spatial task [VAST]) was used to investigate spatial processing of auditory targets when endogenous orientation of spatial attention was mediated by visual cues in healthy adults. A line bisection task (LBT) was also administered to assess the presence of a leftward bias in deployment of visuospatial attention. Overall, participants showed rightward and leftward biases in the VAST and the LBT, respectively. | Journal of Advanced Research 18 2019 95-100 Contents lists available at ScienceDirect Journal of Advanced Research journal homepage locate jare Original article Endogenous orientation of visual attention in auditory space Gaetana Chillemia 1 Alessandro Calamuneria 1 Angelo Quartarone b 2 Carmen Terranovac Adriana Salatino d Alberto Cacciola a b Demetrio Milardia b Raffaella Riccid Check for updates a IRCCS Centro Neurolesi Bonino Pulejo Contrada Casazza SS113 98124 Messina Italy b Department of Biomedical and Dental Sciences and Morphofunctional Imaging University of Messina Via Consolare Valeria 1 Gazzi 98125 Messina Italy c Department of Clinical and Experimental Medicine Endocrinology University of Messina Via Consolare Valeria 1 Gazzi 98125 Messina Italy d Department of Psychology University of Torino Torino 10123 Italy HIGHLIGHTS GRAPHICAL ABSTRACT Facilitation was observed for rightsided auditory stimuli in a new visuo-audio task. Auditory space has dynamic nature which adapts to changes in visual space. Sound localization was enhanced by visual cues. Crossmodal links in spatial attention were found between audition and vision. These findings have theoretical and translational implications for future studies. Using an visuo-audio spatial task a novel version of the Posner task we support the idea that auditory and visual attentional systems are governed by modality-specific processes and provide novel evidence for audiovisual links in endogenous covert spatial attention.
