Studies show that we can change the representation of the self and self-other boundaries, i.e. induce bodily self-other merging. Indeed, experiencing tactile facial stimulation while seeing similar synchronous stimuli delivered to the face of another individual as in a mirror (IMS procedure), induces the subjective illusory experience of ownership and self-attribution bias of the other’s face (Bufalari et al., 2018).

Over the last thirty years, the actor-partner interdependence model (Kenny, 1996) became an important methodology to address interpersonal perceptions in dyads. In this contribution, we present each practical step to conduct an extended version of it, the actor-partner interdependence mediation model (Ledermann, Macho, & Kenny, 2011) using multilevel modeling. Specifically, we posit that individuals’ and their romantic partners’ positivity, a personality disposition, enhance relationship satisfaction, through the individuals’ perceptions of partners’ positivity.
