Key takeaways
From the reading, NOTE-1006.
- The illusion. Synchronous brushing of a seen rubber hand and the subject’s hidden hand makes subjects feel “the touch not of the hidden brush but that of the viewed brush, as if the rubber hand had sensed the touch”. Three questionnaire items were affirmed reliably: touch felt where the rubber hand was touched, touch caused by the brush on the rubber hand, and “I felt as if the rubber hand were my hand”.
- Ownership comes with it. Subjects who referred touch to the rubber hand also reported it as belonging to them, and eight of ten used words of ownership unprompted.
- Felt position moves. After 30 minutes of exposure, blind intermanual reaches were displaced toward the rubber hand, more so the longer the illusion had been reported (r² 0.47, p<0.03, Fig. 2).
- Synchrony is the cause. With a small asynchrony in the brushing, the illusion was reported for 7% of the exposure against 42%, and reaches moved 13 mm away from the rubber hand rather than 23 mm toward it.
- The interpretation. A constraint-satisfaction process among vision, touch and proprioception, shaped by their normal correlations, reconciles conflicting input by distorting position sense; and intermodal matching “can be sufficient for self-attribution”.
Standing in the record
Filed on 2026-10-19 at the owner’s request to fill the record’s gap around the rubber hand illusion and bodily self-consciousness. Before it, the record held body ownership only at second hand: Metzinger’s “Self models” (LIT-450, NOTE-372) cites full-body illusions (Lenggenhager et al. 2007) for its claim C6 that ownership can be manipulated by multisensory conflict, and none of the primary studies had been read. This is the founding primary report of that kind of manipulation, read in full: Active.
It is a single page with ten subjects, so it establishes the effect and its dependence on synchrony, not its size or mechanism. It bears on THEORY-064, which says such illusions show the self-model can be manipulated but not that it is all there is; on THEORY-458 and the ownership–agency distinction of Gallagher (LIT-453) and Haggard (LIT-1009), since the illusion is ownership produced in a passive hand with no agency at stake; and on the precision-weighted multisensory accounts in the record (LIT-1181), whose reconciliation of conflicting senses it is an early behavioural instance of. The NOTE sets this out.
Filed alongside, in the 2026-10-19 batch on the rubber hand illusion and bodily self-consciousness: Lenggenhager et al. 2007, the full-body illusion (LIT-1279); Blanke & Metzinger 2009, minimal phenomenal selfhood (LIT-1274); Apps & Tsakiris 2014, the free-energy self (LIT-1262); Seth 2013, interoceptive inference (LIT-1263).
Filed from this work on 2026-10-20: THEORY-765, on the synchrony effect itself; THEORY-769, the predictive account of ownership, as the finding it explains.
One of the sources of THEORY-766 (filed 2026-10-20), which restates the rubber hand synchrony effect as a difference in reports, separates drift from those reports, and leaves open whether expectation produces the difference.
