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(More)
People learn modality-independent, conceptual representations from modality-specific sensory signals. Here, we hypothesize that any system that accomplishes this feat will include three components: a representational language for characterizing modality-independent representations, a set of sensory-specific forward models for mapping from(More)
The format of high-level object representations in temporal-occipital cortex is a fundamental and as yet unresolved issue. Here we use fMRI to show that human lateral occipital cortex (LOC) encodes novel 3-D objects in a multisensory and part-based format. We show that visual and haptic exploration of objects leads to similar patterns of neural activity in(More)
This paper presents a computational model of concept learning using Bayesian inference for a grammatically structured hypothesis space, and test the model on mul-tisensory (visual and haptics) recognition of 3D objects. The study is performed on a set of artificially generated 3D objects known as fribbles, which are complex , multipart objects with(More)
