“…Moreover, it is worth noting that inclusion of other in the self was indexed by IOS score, which taps conceptual forms of self-representation [ 79 ], while passability judgments were used to probe representations related to the bodily-self. Hence, consistent with previous work, our results suggest an interaction between conceptual- and bodily-self [ 35 , 86 , 87 ].…”

Self-partner inclusion predicts performance of romantically involved individuals in a body-scaled action-anticipation task

Previous research has shown that romantic relationships can lead to the cognitive inclusion of a romantic partner into one’s own self-representation, resulting in blurred boundaries between self and intimate other. Recent work suggests that this self-other integration process encompasses the two dimensions of the self–the conceptual and the bodily self. In line with this, it has been proposed that romantic love is associated with cognitive states that blur or reduce the saliency of self-boundaries in the bodily domain. The present study tested this hypothesis by investigating the influence of the self-other integration process in romantic love on passability judgments of door-like apertures, an action-anticipation task that rests on the representation of bodily boundaries. Romantically involved and single participants estimated whether they could pass through apertures of different widths. Moreover, inclusion of romantic partner in the self was assessed using the Inclusion of Other in the Self (IOS) scale. The pattern of correlation and the ratio between participants’ shoulder width and aperture judgments did not differ between romantically involved participants and singles. However, our results revealed that in romantically involved participants, the relationship between individuals’ shoulder width and aperture judgements was moderated by IOS scores. A greater inclusion of romantic partner in the self was associated with a weaker prediction of aperture judgment by participants’ shoulder width. A similar moderating effect of the intensity of romantic feelings (as measured by the passionate love scale) on shoulder width-aperture judgment relationship was found. IOS scores, but not romantic feelings, also moderated aperture judgments made for another individual (third person perspective). Together, these findings are consistent with the view that inclusion of romantic partner in the self triggers cognitive states affecting self-boundaries in the bodily domain.

“…We expected that participants would self-identify more with the seen face and experience a stronger sense of agency in the synchronous compared to the asynchronous condition. In line with previous studies using the enfacement illusion, synchronous stimulation was further expected to enhance perceived similarity [8] and attractiveness [28] of the observed face. Finally, we expected that participants' gender identity would shift more towards the opposite of the self-identified gender in the synchronous compared to the asynchronous condition.…”

Fluid face but not gender: Enfacement illusion through digital face filters does not affect gender identity

It has been shown that observing a face being touched or moving in synchrony with our own face increases self-identification with the former which might alter both cognitive and affective processes. The induction of this phenomenon, termed enfacement illusion, has often relied on laboratory tools that are unavailable to a large audience. However, digital face filters applications are nowadays regularly used and might provide an interesting tool to study similar mechanisms in a wider population. Digital filters are able to render our faces in real time while changing important facial features, for example, rendering them more masculine or feminine according to normative standards. Recent literature using full-body illusions has shown that participants’ own gender identity shifts when embodying a different gendered avatar. Here we studied whether participants’ filtered faces, observed while moving in synchrony with their own face, may induce an enfacement illusion and if so, modulate their gender identity. We collected data from 35 female and 33 male participants who observed a stereotypically gender mismatched version of themselves either moving synchronously or asynchronously with their own face on a screen. Our findings showed a successful induction of the enfacement illusion in the synchronous condition according to a questionnaire addressing the feelings of ownership, agency and perceived similarity. However, we found no evidence of gender identity being modulated, neither in explicit nor in implicit measures of gender identification. We discuss the distinction between full-body and facial processing and the relevance of studying widely accessible devices that may impact the sense of a bodily self and our cognition, emotion and behaviour.

“…Recognizing oneself based solely on static images might lead to a broader boundary of self-recognition, potentially embodying others within oneself and representing oneself more within others 14,17,62 . In contrast, recognizing oneself from moving images might result in a more stringent boundary of self-identification.…”

“…Moreover, shifts in self-face recognition induced by multisensory stimulation have been reported to be influenced by various factors. For instance, the boundaries between self and others have been associated with social traits, perceptual and social binding, relationships, and attractiveness 13,14,18,[22][23][24][25] , schizophrenia disorder 26,27 , personal bias 28 . These phenomena exhibit similarities with the sense of body ownership 29,30 , and are beginning to be elucidated in connection with neural activity 15,20,26,31 .Previous studies have utilized morphing still images to investigate self-recognition, aiming to explore the boundaries between the self and others.…”

Face recognition is a crucial aspect of self-image and social interactions. Previous studies have focused on static images to explore the boundary of self-face recognition. Our research, however, investigates the dynamics of face recognition in contexts involving motor-visual synchrony. We first validated our morphing face metrics for self-face recognition. We then conducted an experiment using state-of-the-art video processing techniques for real-time face identity morphing during facial movement. We examined self-face recognition boundaries under three conditions: synchronous, asynchronous, and static facial movements. Our findings revealed that participants recognized a narrower self-face boundary with moving facial images compared to static ones, with no significant differences between synchronous and asynchronous movements. The direction of morphing consistently biased the recognized self-face boundary. These results suggest that while motor information of the face is vital for self-face recognition, it does not rely on movement synchronization, and the sense of agency over facial movements does not affect facial identity judgment. Our methodology offers a new approach to exploring the ‘self-face boundary in action’, allowing for an independent examination of motion and identity.
