We know much about the social and affective importance of shared experiences, but the epistemic benefits of perceiving together, by contrast, are much less explored. Is there something special when we sense things together? Can we explain and quantify the epistemic benefits of shared perception? Can we use this knowledge to improve collective experience, notably in online and virtual environments?
In this project, we propose that joint attention is a fundamentally multisensory phenomenon. We study how different senses shape joint attention and, conversely, how joint attention can affect perception across modalities.
