Overview of experimental block design. All blocks consisted of randomly interspersed auditory-only (a), visual-only (v), and simultaneous audiovisual (av) stimuli, labeled in each frame. The auditory and visual constituent stimuli of audiovisual trials matched during the two congruent blocks and did not match on incongruent blocks. Target stimuli (animal words) in each block stream are depicted in uppercase (though they did not differ in actual salience during the experiment). During the focused visual attention blocks, participants detected visual animal word targets occurring in either the V or AV stream. During the distributed audiovisual attention blocks, participants detected animal targets occurring in either of three stimulus streams.
