Body motion perception is associated with the movement or change of the position in 3D space experienced by a human when submitted to xteroceptive (visual, vestibular, haptic) or proprioceptive information. Independently of the inductive stimulation, body motion perception is called “global” when it involves the whole body and “segmental” when it involves body parts. It can be linear, circular or curvilinear (both linear and circular). Starting with the vestibular effects on perception and subjective posture in 3D space and analysing the importance of visual information on spatial linear navigation, the cognitive and visuo-vestibular effects on body motion perception will be explained in experimental and naturalistic virtual environments. Based on the motor simulation hypothesis, motor imagery of segmental and global body motion will be considered a perception-action process mentally represented. Expressed in a continuum, the aim of the presentation is to contribute to the understanding of the behavioural and neural components of body motion perception in the real, virtual and simulated world.
