People's experience is shaped by the sensory experience, which relies on other senses to process information. This is crossmodality. The interactions between senses change how the other senses are processed. For example, the interactions of sight and somatosensation is proprioception. This is only true in sighted individuals, and blind individuals have different ways of proprioception. Plasticity of the brain allows crossmodality to be effective. Crossmodality can both enhance and hinder sensory expereinces and how people perceive the world.
