Visuo-haptic multisensory object recognition, categorization, and representation

Simon Lacey, K. Sathian
2014 Frontiers in Psychology  
Visual and haptic unisensory object processing show many similarities in terms of categorization, recognition, and representation.  ...  In particular, we show that similar unisensory visual and haptic representations lead to a shared multisensory representation underlying both cross-modal object recognition and view-independence.  ...  A MODEL OF VISUO-HAPTIC MULTISENSORY OBJECT REPRESENTATION Haptic activation of the LOC might arise from direct somatosensory input.  ...

in visuo-haptic object recognition.  ...  Yet, vision might dominate visuo-haptic interactions as it is more effective than haptics in processing several object features in parallel and recognizing objects outside of reaching space.  ...  When familiar objects were recognized via reliable visual and haptic input, only haptic but not visual object recognition showed a brain activation pattern that is reconcilable with visuo-haptic interactions  ...
