dc.description.abstractOur brain has a remarkable capacity for learning movements and adapting them to accomplish a motor goal. In many adaptation studies, participants move in a 2D plane while their hand is represented by a cursor. When visual feedback of hand position is misaligned, people can quickly compensate for this perturbation, show persistent reach aftereffects, and even misestimate the location of the unseen hand in the direction of previous visual training. However, it is unknown how well this generalizes to real-world settings or to the tools we use every day. Immersive virtual reality was used to test if end-effector shifts are also observed in more naturalistic virtual reality environments and if they extend to tools as end effectors. In the Hand Experiment, previous work from our lab was replicated where we found shifts in end-effector localization after adapting reach movements to a 30° and 60° visuomotor rotation of the hand, showing a similar magnitude of both shifts in where people indicate their perceived/felt hand and reach aftereffects following training to the perturbation in the VR environment. In the Pen Experiment, this paradigm was extended to investigate how well people can adapt when aiming with a common tool, like a pen, and whether the tool location is also recalibrated. The extent that the unseen location of hand-held tool, as well as the hand (in separate trials) recalibrates with adaptation was measured. Our results provide insight into the adaptative processes involved when learning to wield tools in more complicated, realistic environments.
