Crossmodal information for visual and haptic discrimination
Both our visual and haptic systems contribute to the perception of the three dimensional world, especially the proximal perception of objects. The interaction of these systems has been the subject of some debate over the years, ranging from the philosophically posed Molyneux problem to the more pragmatic examination of their psychophysical relationship. To better understand the nature of this i...
متن کاملCrossmodal short-term memory of haptic and visual information.
Rhesus monkeys were trained on a within-subjects design to assess whether they could perform concurrently visual-to-haptic (V-H) and haptic-to-visual (H-V) crossmodal delayed matching-to-sample (DMS). A parametric analysis was conducted of the effect of delay between presentation and re-presentation of the test discriminanda (three-dimensional geometric objects). The results indicate that (a) m...
متن کاملHaptic Shape Processing in Visual Cortex
Humans typically rely upon vision to identify object shape, but we can also recognize shape via touch (haptics). Our haptic shape recognition ability raises an intriguing question: To what extent do visual cortical shape recognition mechanisms support haptic object recognition? We addressed this question using a haptic fMRI repetition design, which allowed us to identify neuronal populations se...
متن کاملShape Matching in Visual Data
Acknowledgements First and foremost, I would like to thank my advisors Professor Andrea Massa and Professor Francesco G.B. De Natale who taught me a lot about research and life in general. They were always there to provide everything not only to support my research but also to help me adjust myself in new country as Italy. Without their guidance and support, this thesis would not have been comp...
متن کاملCrossmodal Association of Visual and Haptic Material Properties of Objects in the Monkey Ventral Visual Cortex
Just by looking at an object, we can recognize its non-visual properties, such as hardness. The visual recognition of non-visual object properties is generally accurate [1], and influences actions toward the object [2]. Recent studies suggest that, in the primate brain, this may involve the ventral visual cortex, which represents objects in a way that reflects not only visual but also non-visua...
