Abstract

We investigate the hypothesis that multisensory representations mediate the crossmodal transfer of shape knowledge across visual and haptic modalities. In our experiment, participants rated the similarities of pairs of synthetic 3-D objects in visual, haptic, cross-modal, and multisensory settings. Our results offer two contributions. First, we provide evidence for a single multisensory shape representation common to both visual and haptic modalities. Second, our analyses suggest that these representations are part-based, representing objects as compositions of subparts.
