Effect of Distorted Visual Feedback on the Sense of Agency
Open accessAbstract
It has been hypothesized that an internal model is involved in controlling and recognizing one’s own actions (action attribution). This results from a comparison process between the predicted sensory feedback of the action and its real sensory consequences. The aim of the present study is to distinguish the respective importance of two action parameters (time and direction) on such an attribution judgment. We used a device that allows introduction of discordance between the movements actually performed and the sensory feedback displayed on a computer screen. Participants were asked to judge whether they were viewing (1) their own movements, (2) their own movements modified (spatially or temporally displaced), or (3) those of another agent (i.e, the experimenter). In fact, in all conditions they were only shown their own movements either unaltered or modified by varying amounts in space or time. Movements were only attributed to another agent when therewas a high spatial discordance between participants’ hand movements and sensory feedback. This study is the first to show that the direction of movements is a cardinal feature in action attribution, whereas temporal properties of movements play a less important role.

TL;DR
This study used a joystick/virtual-hand setup to test whether spatial or temporal visual feedback distortion affects action attribution. It found that large angular deviations led participants to attribute their own movements to another agent, whereas even long temporal delays almost never did.
Key findings
- In the spatial condition, participants gave more “self” responses for biases between 0° and 15°, more “bias” responses for biases between 20° and 30° (p < 0.05), and more “other” responses for biases between 50° and 60° (p < 0.05); transitions occurred between 15°–20° and 30°–50°.
- In the temporal condition, participants never gave an “other” response; they gave significantly more “self” responses for biases between 0 ms and 50 ms (p < 0.05) and more “bias” responses for biases between 150 ms and 1100 ms (p < 0.05).
- Repeated measures ANOVA showed a significant main effect of response, F(2, 38) = 86.05, p < 0.0001, and significant interactions: response × bias value, F(26, 494) = 165.11, p < 0.0001; response × modality, F(2, 38) = 188.40, p < 0.0001; and three-way interaction, F(26, 494) = 64.63, p < 0.0001.
- Post-hoc tests found significantly more “bias” responses in the temporal modality than in the angular modality (p < 0.0001), and more “other” responses in the angular modality than in the temporal modality (p < 0.0001), with no significant difference for “self” responses between modalities.
Methods
- Twenty participants (mean age 29.8 ± 10.95; average Edinburgh handedness score 79.05 ± 32.04) held a joystick with their right hand and made random movements while viewing a virtual hand via a mirror, with no direct view of their own hand.
- Trials included neutral movements, 13 angular bias values (5°, 10°, 15°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°), and 13 temporal bias values (50, 100, 150, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100 ms); each value was repeated 10 times, yielding 270 trials per participant in pseudo-random order.
- Participants verbally judged each trial as “self,” “bias,” or “other”; responses were analyzed with repeated measures ANOVA (factors: response, modality, bias value) and pairwise t-tests.
Limitations
- The paper does not state limitations explicitly.
- Evident from the text: participants were told they might see the experimenter’s movements, but in reality they were never shown the experimenter’s movements, so “other” responses reflect misattribution of their own modified movements rather than detection of another agent.
- Evident from the text: the sample was 20 participants, predominantly right-handed, using only right-hand joystick movements, and only angular and temporal distortions were tested, which may limit generalization.

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.
