PROprioCEption in Sensory Substitution (PROCESS)
My PhD research focuses on sensory substitution and the interaction between perception, action, and proprioception. It investigates how different types of movement (active or passive) and exploration strategies affect shape recognition, proprioceptive accuracy, and motor performance, as well as the impact of multisensory feedback (auditory and tactile) on perceptual and motor learning. The work combines fundamental research on perceptual mechanisms with potential applications in sensorimotor rehabilitation.
