Conversations between self and self as Sigmund Freud—A virtual body ownership paradigm for self counselling

Abstract

When people see a life-sized virtual body (VB) from first person perspective in virtual reality they are likely to have the perceptual illusion that it is their body. Additionally such virtual embodiment can lead to changes in perception, implicit attitudes and behaviour based on attributes of the VB. To date the changes that have been studied are as a result of being embodied in a body representative of particular social groups (e.g., children and other race). In our experiment participants alternately switched between a VB closely resembling themselves where they described a personal problem and a VB representing Dr Sigmund Freud, from which they offered themselves counselling. Here we show that when the counsellor resembles Freud participants improve their mood, compared to the counsellor being a self-representation. The improvement was greater when the Freud VB moved synchronously with the participant, compared to asynchronously. Synchronous VB movement was associated with a much stronger illusion of ownership over the Freud body. This suggests that this form of embodied perspective taking can lead to sufficient detachment from habitual ways of thinking about personal problems, so as to improve the outcome and demonstrates the power of virtual body ownership to effect cognitive changes.

TL;DR

In immersive virtual reality, male participants alternately embodied a lookalike self and a virtual Sigmund Freud counsellor to discuss a personal problem. Embodiment as Freud improved mood and happiness more than embodiment as the self, especially when the Freud body moved synchronously with the participant and elicited stronger body ownership.

Key findings

  • Body ownership and agency over the counsellor body were substantially higher with visuomotor synchrony than asynchrony: for MeDown, MeMirror, and MyMovements, Wilcoxon rank-sum tests gave P = 0.003, 0.015, and 0.0001, respectively.
  • In the within-groups experiment (n = 12), the Freud counsellor produced greater mood improvement than the Self counsellor: the marginal difference in dPOMSTotal had a 95% CI of −8.02 to −0.14, and dSAMHappy Freud minus Self had a 95% CI of 0.17 to 1.43.
  • Overall mood improved pre- to post-experiment: POMS differences were significant in the Async condition (P = 0.005) and Sync condition (P = 0.0001); SAMHappy differences were significant in Async (P = 0.027) and Sync (P = 0.0003).
  • In the between-groups comparison of visuomotor conditions, dPOMSTotal showed no significant main or interaction effect for Visuomotor, but greater body ownership over the Freud body (MyBodyPCA) interacted with SUDS such that greater ownership was associated with greater mood improvement.

Methods

  • Experiment 1 was a within-groups design (n = 12): each participant discussed a different personal problem one week apart, once with a Freud counsellor and once with a lookalike Self counsellor, counterbalanced, with visuomotor synchrony. Experiment 2 added 10 participants who always had the Freud counsellor but with visuomotor asynchrony while embodied as Freud, compared with the 12 synchronous Freud cases from Experiment 1.
  • Participants were 22 males, mean ± SD age 24 ± 5, recruited around the University of Barcelona; they were body-scanned to create lookalike avatars, wore an Oculus DK2 HMD and XSens MVN motion capture suit, and in the Freud condition their recorded voice was pitch-lowered by 2 semitones.
  • Measures included SUDS for problem severity screening, POMS and Self Assessment Manikin (SAMHappy, SAMIntensity) before and after, and body-ownership/agency questions (MeDown, MeMirror, MyMovements, LikeMe); MeDown and MeMirror were combined via polychoric PCA into MyBodyPCA. Analyses used non-parametric tests where possible, mixed-effects regression for Experiment 1, and ANCOVA for Experiment 2.

Limitations

  • The paper states that the experiment cannot determine whether the result is due to the Freud body specifically, with its strong therapy association, or whether another body would have worked as well.
  • The paper states that participants presented fairly mild personal problems, outcomes were assessed only through questionnaires, and further study is needed with more severe issues, actual outcomes, and long-term follow-up.
  • Evident from the text: the sample was small (22 males total), all male, and recruited from a university campus, limiting generalizability; the qualitative interview data were not analyzed in this paper.

    “the body associated with this different perspective representing another person, in this case strongly associated with therapy”
  • The authors state this as an assumption.

    Change in mood after the experience compared to before is correlated with SUDS, since if the original level of discomfort was already low there is not much room for change.

    “It is reasonable that the change in mood after the experience compared to before might be correlated with the SUDS, since if the original level of discomfort was already low there is not much room for change.”
  • The paper relies on this without support.

    Participants have full access to all necessary information about their problem in autobiographical memory.

    “Moreover the participants also normally have full access to all the necessary information about their problem, residing in their autobiographical memory.”

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In the earlier study, being embodied as Freud with synchronous visuomotor feedback produced better outcomes than asynchronous feedback.

    “Moreover, being embodied as Freud with synchronous visuomotor feedback, corresponding to a strong illusion of body ownership over the Freud body, produced better outcomes compared with asynchronous visuomotor feedback corresponding to low body ownership.”
  • In the earlier study, self-counselling produced better mood and happiness outcomes when participants were embodied as Freud compared to a duplicate of their own body.

    “We showed in the earlier study2 that the self-counselling technique produced better outcomes, in terms of improving the mood and happiness of participants with respect to their initial problem, when participants were embodied as the counsellor in the Freud virtual body compared to the counsellor being another duplicate of their own body.”
  • Osimo et al. introduced a VR self-counselling technique in which participants alternate between their own virtual body and a virtual Freud body to maintain a self-conversation.

    “Osimo, et al.2 introduced such a technique for self-counselling. Participants were embodied in scanned copies of themselves in immersive virtual reality (VR) and explained a personal problem to a virtual representation of Dr Sigmund Freud.”
  • In the SC group, body ownership did not differ between the Freud and own body.

    “In the SC group the level of body ownership was not different with respect to the Freud and own body, replicating what was found in2.”
  • In the earlier study, on average participants improved mood and happiness irrespective of condition; simply talking about the problem was sufficient for some improvement.

    “Although, being embodied as Freud with synchronous visuomotor feedback produced the best overall outcomes, on the average participants improved their mood and happiness with respect to their personal problem irrespective of the experimental condition: simply talking about their problem was sufficient to lead to some improvement.”

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Conditions differed in more than visuomotor synchrony

    Minor

    The claimed sole difference omits the reversed order of the preparatory embodiment phases and the fact that asynchronous participants visited only once, whereas synchronous participants came from the two-visit experiment.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

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.
