Keeping in touch with one’s self: multisensory mechanisms of self-consciousness
Open accessAbstract
BACKGROUND: The spatial unity between self and body can be disrupted by employing conflicting visual-somatosensory bodily input, thereby bringing neurological observations on bodily self-consciousness under scientific scrutiny. Here we designed a novel paradigm linking the study of bodily self-consciousness to the spatial representation of visuo-tactile stimuli by measuring crossmodal congruency effects (CCEs) for the full body. METHODOLOGY/PRINCIPAL FINDINGS: We measured full body CCEs by attaching four vibrator-light pairs to the trunks (backs) of subjects who viewed their bodies from behind via a camera and a head mounted display (HMD). Subjects made speeded elevation (up/down) judgments of the tactile stimuli while ignoring light stimuli. To modulate self-identification for the seen body subjects were stroked on their backs with a stick and the felt stroking was either synchronous or asynchronous with the stroking that could be seen via the HMD. We found that (1) tactile stimuli were mislocalized towards the seen body (2) CCEs were modulated systematically during visual-somatosensory conflict when subjects viewed their body but not when they viewed a body-sized object, i.e. CCEs were larger during synchronous than during asynchronous stroking of the body and (3) these changes in the mapping of tactile stimuli were induced in the same experimental condition in which predictable changes in bodily self-consciousness occurred. CONCLUSIONS/SIGNIFICANCE: These data reveal that systematic alterations in the mapping of tactile stimuli occur in a full body illusion and thus establish CCE magnitude as an online performance proxy for subjective changes in global bodily self-consciousness.

TL;DR
This paper links full-body multisensory conflict to tactile spatial representation by measuring crossmodal congruency effects (CCEs) for vibrotactile targets and LED distractors on the back. It reports that full-body CCEs are modulated by seeing one’s body and by synchronous versus asynchronous stroking, and that these changes accompany altered self-identification and self-location.
Key findings
- Full-body CCEs were present when subjects viewed their body: in Study 1, the body × side × congruency interaction was significant (F1,10 = 10.13, p = 0.01), and the CCE was larger for same-side than different-side visual distractors when the body was visible (t1,10 = 3.22, p = 0.009) but not when it was not visible (t1,10 = 0.83, p > 0.05).
- With a 233 ms LED–vibration SOA, stroking type modulated the CCE: Study 2 showed a significant stroking × side × congruency interaction (F1,12 = 11.30, p = 0.006), with a larger same-side versus different-side CCE during synchronous stroking (t1,12 = 4.01, p = 0.002) but not asynchronous stroking (t1,12 = 2.17, p > 0.05).
- In Study 2, synchronous stroking produced a mean self-location drift of 8.1 cm toward the virtual body versus 0.1 cm in the asynchronous condition (t1,12 = 2.21, p = 0.047), and higher questionnaire ratings for touch location (Q1: z = 2.8, p = 0.005) and self-identification with the virtual body (Q3: z = 2.3, p = 0.020).
- In the object control (Study 3), no significant CCE effects were found for the object condition, while the body condition replicated the synchronous-stroking effect (same vs different side: t1,8 = 2.60, p = 0.031; asynchronous: t1,8 = 0.39, p > 0.05).
Methods
- Thirty-five healthy right-handed subjects participated across three studies: Study 1 n = 13 (8 males, mean age 24), Study 2 n = 13 (9 males, mean age 26), and Study 3 n = 9 (6 males, mean age 23); two Study 1 subjects were excluded from analyses for chance-level performance, and different subjects took part in each study.
- Subjects stood 2 m in front of a 3D camera and viewed their backs via a head-mounted display; four vibrator–light pairs were attached to their backs, and stroking was applied synchronously or asynchronously (400 ms camera delay). They made speeded up/down tactile judgments while ignoring lights; CCE was computed as RT in incongruent minus congruent trials. Study 1 used a 33 ms LED–vibration SOA, while Studies 2 and 3 used 233 ms.
- Analyses used repeated-measures ANOVAs with factors including body/stroking type, side, and congruency; drift and questionnaire measures were analyzed with t-tests and Wilcoxon matched-pairs tests, with alpha = 0.05. Incorrect trials and responses over 1500 ms were discarded, averaging 4.8% of trials per subject.
Limitations
- The paper states that stimuli were applied only to the backs, so non-stimulated body parts may not have been affected and the measured effects may not be fully global; it calls for future studies testing generalization to non-stimulated parts such as the hands.
- The paper states that Study 1’s lack of stroking effects on self-location and self-identification may have resulted from adding the LED–vibration visuo-tactile mismatch to the stroking mismatch, and that the SOA choice may have influenced multisensory weighting; it also notes that the CCE data cannot by themselves determine whether touch or vision is remapped, and discusses alternative explanations such as task relevance, response bias, and visual recoding.
- Evident from the text: the per-study samples were small (13, 13, and 9 subjects), and the object-control questionnaire ratings for self-identification with the object were barely or not positive despite a significant synchronous-versus-asynchronous difference.

In the paper
“The present data suggest that the tactile stimuli are mislocalised to a different place in external space (towards the seen body in the synchronous condition) because the localisation of the body in space is biased towards the seen body (as measured by the drift and questionnaire) in the condition in which the CCEs are larger.”

“These novel data reveal ‘body-related’ and ‘self-related’ CCEs and suggest that under the conditions used in the present study the full body CCE is associated with key components of bodily self-consciousness, i.e. ‘what I experience as my body’ and ‘where I experience my body to be.’”

“Nevertheless, given that there is a change in self-location - as measured by the spatial drift - towards the seen body (i.e. towards the visual stimulus) in the synchronous condition, we suggest that it is touch rather than vision that is mislocalised.”

“Further, our finding that there was no CCE (no significant effect of congruency and no interaction between synchrony, side of visual distractor and congruency) in the object control condition suggests that the effect of stroking on the CCE is specific to the case where the stroking is applied to a human body.”

In the paper
“The present data show that the previously described [17], [18], [25], [27] changes in self-location and self-identification are - under certain experimental conditions - associated with changes in the CCE, and hence with changes in the mapping of tactile stimuli.”

In the paper
“We argue that when the LED-vibro-tactile stimuli were made more asynchronous (by introducing the larger SOA), this may have influenced the differential weighting of all visual and tactile stimuli present, and therefore have affected how the felt stroking and seen stroking were integrated.”

In the paper
“The self-related aspects of the CCE appear to be not simply an effect of seeing a body, but of identifying with the seen body, and having an altered self-location (biased towards the spatial location at which the body is seen).”

The paper relies on this without support.
The crossmodal congruency effect has a relatively large magnitude and is less susceptible to experimenter expectancy effects than previous behavioural proxies of bodily self-consciousness.
“This measure has a number of advantages: its magnitude is relatively large and it is less susceptible to experimenter expectancy effects than previous behavioural proxies of bodily self-consciousness.”
The paper relies on this without support.
The congruency task enables repeated, online measurements during manipulations of self-consciousness, and this has not previously been done in studies of partial or global bodily self-consciousness.
“Moreover, the congruency task enables the collection of repeated, ‘online’ measurements during manipulations of self-consciousness: this has not previously been done in studies of partial or global bodily self-consciousness.”

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.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
