The rubber hand illusion ( RHI ) and its variant the invisible hand illusion ( IHI ) are useful for investigating multisensory aspects of bodily self‐consciousness. Here, we explored whether auditory conditioning during an RHI could enhance the trisensory visuo‐tactile‐proprioceptive interaction underlying the IHI . Our paradigm comprised of an IHI session that was followed by an RHI session and another IHI session. The IHI sessions had two parts presented in counterbalanced order. One part was conducted in silence, whereas the other part was conducted on the backdrop of metronome beats that occurred in synchrony with the brush movements used for the induction of the illusion. In a first experiment, the RHI session also involved metronome beats and was aimed at creating an associative memory between the brush stroking of a rubber hand and the sounds. An analysis of IHI sessions showed that the participants’ perceived hand position drifted more towards the body‐midline in the metronome relative to the silent condition without any sound‐related session differences. Thus, the sounds, but not the auditory RHI conditioning, influenced the IHI . In a second experiment, the RHI session was conducted without metronome beats. This confirmed the conditioning‐independent presence of sound‐induced proprioceptive drift in the IHI . Together, these findings show that the influence of visuo‐tactile integration on proprioceptive updating is modifiable by irrelevant auditory cues merely through the temporal correspondence between the visuo‐tactile and auditory events.
