Abstract:

Experiments with human subjects explored how auditory attention operates. Specifically, the experiments investigated 1 the hypothesis that room reverberation interferes with selective attention, 2 whether selective attention to an ongoing target improves with time when the target has a contiguous feature distinguishing if from competing sources, and 3 how visual cues help direct selective auditory attention through behavioral measures and computational modeling. Results demonstrate that 1 selective attention is adversely affected by room reverberation, 2 continuity of task-irrelevant sound features strongly enhances the ability to maintain attention on a stream based on some other, orthogonal feature, and 3 visual cues can be used to direct selective auditory attention.
