Looking for myself: current multisensory input alters self-face recognition

Open access

Abstract

How do I know the person I see in the mirror is really me? Is it because I know the person simply looks like me, or is it because the mirror reflection moves when I move, and I see it being touched when I feel touch myself? Studies of face-recognition suggest that visual recognition of stored visual features inform self-face recognition. In contrast, body-recognition studies conclude that multisensory integration is the main cue to selfhood. The present study investigates for the first time the specific contribution of current multisensory input for self-face recognition. Participants were stroked on their face while they were looking at a morphed face being touched in synchrony or asynchrony. Before and after the visuo-tactile stimulation participants performed a self-recognition task. The results show that multisensory signals have a significant effect on self-face recognition. Synchronous tactile stimulation while watching another person's face being similarly touched produced a bias in recognizing one's own face, in the direction of the other person included in the representation of one's own face. Multisensory integration can update cognitive representations of one's body, such as the sense of ownership. The present study extends this converging evidence by showing that the correlation of synchronous multisensory signals also updates the representation of one's face. The face is a key feature of our identity, but at the same time is a source of rich multisensory experiences used to maintain or update self-representations.

  • Experimentally induced modulations of body ownership enhance perceived physical similarity between self and other.

    “The first relevant finding to support our argument is that experimentally induced modulations of body ownership enhance perceived physical similarity between self and other.”
  • After experiencing an enfacement illusion, participants accepted morphed photos of faces with a higher percentage of the other as depicting themselves, suggesting that the participants' stored representations of their own faces were altered to incorporate aspects of the other person.

    “In a more objective quantification of a comparable effect, participants accepted morphed photos of faces with a higher percentage of the other as depicting themselves after experiencing an enfacement illusion, suggesting that the participants' stored representations of their own faces were altered to incorporate aspects of the other person [26,35,36].”
  • After the rubber hand illusion, participants rated the rubber hand as more physically similar to their own.

    “For example, after the rubber hand illusion, participants rated the rubber hand as more physically similar to their own [26].”
  • Enfacement produces a measurable bias in self-face recognition, whereby participants perceive the other's face as looking more like their own.

    “produces a measurable bias in self-face recognition, whereby participants perceive the other's face as looking more like their own [26,35,36].”
  • Tsakiris [32] showed that synchronous, but not asynchronous, visuo-tactile stimulation between the participant's own face and a morphed face produced a measurable bias in self-face recognition.

    “Tsakiris [32] showed that synchronous, but not asynchronous, visuo-tactile stimulation between the participant’s own face and a morphed face, containing a blending of the facial features of the participant (50%) with the features of someone else’s face (50%), produced a measurable bias in self-face recognition.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
