| summary | The beneficial consequences of perceiving and integrating information across different sensory systems have been profusely described in recent literature. For example, we often find it easier to hear someone at a noisy party when we can see their face or, can orient more accurately to the blare of an ambulance siren if we can also see its flashing lights. Multisensory phenomena like these have been extensively studied in the laboratory, but often under conditions where attention can be easily focused on the critical stimuli. However, these focused attention conditions are very different from most everyday life environments, where many relevant and irrelevant sensory events can co-occur within a short time window and perhaps at close locations in space. What is more, multisensory coincidences may occur at completely unexpected moments and places. The question I will address is, to which extent multisensory integration is robust to attentionally compromising situations. I will present the results of recent studies across various domains of perception where multisensory integration plays a paramount role. These studies exemplify how selective attention can modulate behavioural and physiological expressions of multisensory integration, how expectation in time can determine grouping across sensory modalities and, how the perception (and perhaps awareness) of tactile events unfolds as information is orchestrated across sensory modalities. Altogether, my intention is to conclude that multisensory integration cannot be understood without its interplay with attention, and that this interplay may lead to have radically different perceptions of otherwise similar sensory combinations. |
