Walking on a line: a motor paradigm using rotation and reflection symmetry to study mental body transformations.
Researchers have recently reintroduced the own-body in the center of the social interaction theory. From the discovery of the mirror neurons in the ventral premotor cortex of the monkey's brain, a human embodied model of interindividual relationship based on simulation processes has been advanced, according to which we tend to embody spontaneously the other individuals' behavior when interacting. Although the neurocognitive mechanisms of the embodiment process have started being described, the mechanisms of self-location during embodiment are still less known. Here, we designed a motor paradigm which allows investigating in ecologically more valid conditions whether we embody another person's intransitive action with an embodied or disembodied self-location. Accordingly, we propose a phenomenological model of self-other interaction showing how perspective-taking mechanisms may relate on mental body transformation and offering a promising way to investigate the different sorts of intersubjectivity.
