“…With regards to the proprioceptive drift results, the non-significant relationship between illusion strength and proprioceptive drift scores is in accordance with some previous studies [50], [52] but inconsistent with other findings [1], [24], [61], [62]. Moreover, the absence of a relationship between proprioceptive drift and schizotypal traits is in accordance with findings reported by Germine et al [29].…”

Is Body Dysmorphic Disorder Associated with Abnormal Bodily Self-Awareness? A Study Using the Rubber Hand Illusion

Evidence from past research suggests that behaviours and characteristics related to body dissatisfaction may be associated with greater instability of perceptual body image, possibly due to problems in the integration of body-related multisensory information. We investigated whether people with body dysmorphic disorder (BDD), a condition characterised by body image disturbances, demonstrated enhanced susceptibility to the rubber hand illusion (RHI), which arises as a result of multisensory integration processes when a rubber hand and the participant's hidden real hand are stimulated in synchrony. Overall, differences in RHI experience between the BDD group and healthy and schizophrenia control groups (n = 17 in each) were not significant. RHI strength, however, was positively associated with body dissatisfaction and related tendencies. For the healthy control group, proprioceptive drift towards the rubber hand was observed following synchronous but not asynchronous stimulation, a typical pattern when inducing the RHI. Similar drifts in proprioceptive awareness occurred for the BDD group irrespective of whether stimulation was synchronous or not. These results are discussed in terms of possible abnormalities in visual processing and multisensory integration among people with BDD.

“…Secondly, the viewed body orientation provides a further important cue for one's own body: viewing a hand with fingers pointing away from one's trunk is anatomically more plausible for one's own hand than viewing a hand with the opposite orientation. The importance of this body ownership cue has been demonstrated also with the rubber hand illusion paradigm (Ehrsson et al 2004;Holle et al 2011;Ide 2013).…”

The plausibility of visual information for hand ownership modulates multisensory synchrony perception

We are frequently changing the position of our bodies and body parts within complex environments. How does the brain keep track of one's own body? Current models of body ownership state that visual body ownership cues such as viewed object form and orientation are combined with multisensory information to correctly identify one's own body, estimate its current location and evoke an experience of body ownership. Within this framework, it may be possible that the brain relies on a separate perceptual analysis of body ownership cues (e.g. form, orientation, multisensory synchrony). Alternatively, these cues may interact in earlier stages of perceptual processing-visually derived body form and orientation cues may, for example, directly modulate temporal synchrony perception. The aim of the present study was to distinguish between these two alternatives. We employed a virtual hand set-up and psychophysical methods. In a two-interval force-choice task, participants were asked to detect temporal delays between executed index finger movements and observed movements. We found that body-specifying cues interact in perceptual processing. Specifically, we show that plausible visual information (both form and orientation) for one's own body led to significantly better detection performance for small multisensory asynchronies compared to implausible visual information. We suggest that this perceptual modulation when visual information plausible for one's own body is present is a consequence of body-specific sensory predictions.

“…Therefore, it could be argued that the lack of a relationship between one aspect of the RHI (i.e., the explicit questionnaire) and hypnotic suggestibility implies no relationship between HS and the rubber hand illusion, as classically proposed. However, recent behavioural (Holle et al 2011;Kammers et al 2009;Wold et al 2014) and neuroimaging (Tsakiris et al 2007) findings have indicated that the RHI is a multi-facetted and complex illusion which can be broken down into separate constructs (e.g. Figure 1) and that separate cognitive multisensory mechanisms underlie different aspects of the illusion (Blanke 2012;Makin et al 2008;Rohde et al 2011;Tsakiris et al 2010).…”

Are You Suggesting That’s My Hand? The Relation Between Hypnotic Suggestibility and the Rubber Hand Illusion

et al. 2015

Abstract. Hypnotic suggestibility (HS) is the ability to respond automatically to suggestions and to experience alterations in perception and behaviour. Hypnotically suggestible participants are also better able to focus and sustain their attention on an experimental stimulus. The present study explores the relation between HS and susceptibility to the rubber hand illusion (RHI). Based on previous research with visual illusions, it was predicted that higher HS would lead to a stronger RHI illusion. Two behavioural output measures of the RHI, an implicit (proprioceptive drift) and an explicit (RHI questionnaire) measure were correlated against HS scores. Hypnotic suggestibility correlated positively with the implicit RHI measure contributing to 30% of the variation. However, there was no relation between HS and the explicit RHI questionnaire measure, or with compliance control items. High hypnotic suggestibility may facilitate, via attentional mechanisms, the multisensory integration of visuoproprioceptive inputs that leads to greater perceptual mislocalisation of a participant's hand. These results may provide insight into the multisensory brain mechanisms involved in our sense of embodiment.
