Description: The mental representations of the body in action can be explored using motor imagery (MI) tasks (Scarpina et al., 2019). MI tasks can be allocated along a continuum, going from more implicit to more explicit tasks. More implicit and more explicit refers to the different levels of awareness required to execute the task (Longo, 2015; Scarpina et al., 2019). An example of a more implicit task is provided by the laterality judgement tasks, such as the hand laterality task (Parsons, 1987) and the foot laterality task (Curtze, Otten, & Postema, 2010), in which individuals are asked to judge if a visual stimulus represents a left or a right limb. The tasks are solved using implicit motor strategy, that is the imagery of rotating the position of the real hand to match the visual hand. On the other hand, an example of a more explicit task is provided by the mental motor chronometry task (Schwoebel & Coslett, 2005; Sirigu et al., 1996), where individuals are asked to perform or to imagine performing movements with their limbs. However, in the literature, there is a gap in terms of comparison between MI ability of hands and feet, especially when body awareness (more implicit VS more explicit MI tasks) is taken into account. Similarly, we do not know the impact of perceiving our own body status, which can be defined as a conscious representation of our interoceptive states (Mehling, Acree, Stewart, Silas, & Jones, 2018; Mehling et al., 2012).
