While numerous studies have investigated this preference for visually-guided grasping (a left-hemisphere specialization), very few have documented it during haptically-guided actions (a right-hemisphere specialization). In a series of four studies, participants (healthy adults, congenitally blind, and children) were asked to replicate 3D-block models from a tabletop of blocks while the hand used for grasping was recorded. Overall the results showed a right-hand preference for grasping independent of age and visual experience (but not sensory modality). Haptics played a modest, yet significant, role in modulating hand preference, as there was a significant reduction in right-hand use in the absence of vision (i.e. during haptically-guided grasping). Because the left hand was never used more than 50% of the time, these findings support the theory of a default right-hand/left-hemisphere specialization for grasping that is modulated by haptics.","abstract_html":"The purpose of this thesis was to investigate the sensory contributions to hand preference for grasping.
