The role of attention in multisensory processing and feature integration

Duke University, United States
For many years, the processes underlying the integration of the stimulus components of a multisensory object were thought to be essentially automatic. In recent years, however, multiple studies have provided evidence that the integrative interactions between multisensory stimulus components can be modulated by top-down cognitive factors such as attention. Our ERP recordings have shown that the integration of auditory and visual stimuli differs at spatially attended versus spatially unattended locations and that spatial attention to one modality can spread across both modalities and across space, such as occurs during the ventriloquism phenomenon. These findings have important implications for understanding the mechanisms of multisensory feature binding and object processing and underscore the critical role played by attention.
