Koelewijn, T. (author), Bronkhorst, A. (author), Theeuwes, J. (author), TNO Defensie en Veiligheid (author)There is debate in the crossmodal cueing literature as to whether capture of visual attention by means of sound is a fully automatic process. Recent studies show that when visual attention is endogenously focused sound still captures attention. The current study investigated whether there is interaction between exogenous auditory and visual...article 2009
