“…From perception research, we know that once an illusion or stimulus stops after a period of adaptation, there tends to be an aftereffect directed in the opposite direction to the illusion or stimulus presented. This has been shown, for example, in unimodal visual (Bednar 2013 ; Fernández-Ruiz et al 2004 ) and proprioceptive illusions (Goodwin et al 1972 ; Kito et al 2006 ; Perasso et al 2019 ; Seizova-Cajic et al 2007 ), as well as in multisensory illusions, such as the ventriloquism aftereffect (Sato et al 2007 ) or the face recognition aftereffect (Pond et al 2013 ). This study does not examine the aftereffect of the rubber hand illusion per se; rather, it examines the perseverance of two commonly used illusion measures after the end of the visuotactile stimulation.…”

The rubber hand illusion is a perceptual illusion in which participants experience an inanimate rubber hand as their own when they observe this model hand being stroked in synchrony with strokes applied to the person’s real hand, which is hidden. Earlier studies have focused on the factors that determine the elicitation of this illusion, the relative contribution of vision, touch and other sensory modalities involved and the best ways to quantify this perceptual phenomenon. Questionnaires serve to assess the subjective feeling of ownership, whereas proprioceptive drift is a measure of the recalibration of hand position sense towards the rubber hand when the illusion is induced. Proprioceptive drift has been widely used and thought of as an objective measure of the illusion, although the relationship between this measure and the subjective illusion is not fully understood. Here, we examined how long the illusion is maintained after the synchronous visuotactile stimulation stops with the specific aim of clarifying the temporal relationship in the reduction of both subjective ownership and proprioceptive drift. Our results show that both the feeling of ownership and proprioceptive drift are sustained for tens of seconds after visuotactile stroking has ceased. Furthermore, our results indicate that the reduction of proprioceptive drift and the feeling of ownership follow similar time courses in their reduction, suggesting that the two phenomena are temporally correlated. Collectively, these findings help us better understand the relationships of multisensory stimulation, subjective ownership, and proprioceptive drift in the rubber hand illusion.
