¿Hasta dónde llega el esquema corporal? Esquema corporal extendido

This work aims to uphold that a subject‘s body schema can be extended beyond their physical body, that is, that external artifacts, such as tools, can be a part of the said body schema. To support this thesis a new definition of ―body schema‖ is proposed, one that starts by pointing out that body schema as a sub-personal sensorimotor is a necessary condition, albeit not a sufficient one, besides pursuing to include environmental interactions as a sufficient condition. Together, these elements favor the generation and modification of body schema and, consequently, its extension.
