“…In line with previous studies investigating plasticity of body representation by inducing bodily illusions (e.g., Botvinick and Cohen, 1998;Tsakiris, 2008;Sforza et al, 2010), we ensured that the first block lasted a sufficient amount of time to induce 9 plastic changes in the cortical representation of the participant's left hand. For this reason the first block of visuo-tactile stimulation lasted 5 min, whereas the other three 'top up' blocks lasted 1 min each.…”

Chronic pain and impaired tactile sensitivity are frequently associated with "blurred" representations in the somatosensory cortex. The factors that produce such somatosensory blurring, however, remain poorly understood. We manipulated visuotactile congruence to investigate its role in promoting somatosensory reorganization.To this aim we used the mirror box illusion that produced in participants the subjective feeling of looking directly at their left hand, though they were seeing the reflection of their right hand. Simultaneous touches were applied to the middle or ring finger of each hand. In one session, the same fingers were touched (for example both middle fingers), producing a congruent percept; in the other session different fingers were touched, producing an incongruent percept. In the somatosensory system, 3

“…This perceptual effect is accompanied by a subjective illusion that the other face belongs to the observer. This bias in self-recognition or Òenfacement effectÓ (Sforza, Bufalari, Haggard, & Aglioti, 2010) has been shown with totally unfamiliar (TajaduraJimŽnez et al, 2012a), familiar (Sforza et al, 2010), and other-race faces (Bufalari, Lenggenhager, Porciello, Serra-Holmes, & Aglioti, 2014;Fini, Cardini, TajaduraJimŽnez, Serino, & Tsakiris, 2013).…”

This study focuses on learning of the self, by examining how human observers update internal representations of their own face. For this purpose, we present a novel gazecontingent paradigm, in which an onscreen face either mimics observersÕ own eye-gaze behaviour (in the congruent condition), moves its eyes in different directions to that of the observers (incongruent condition), or remains static and unresponsive (neutral condition). Across three experiments, the mimicry of the onscreen face did not affect observersÕ perceptual self-representations. However, this paradigm influenced observersÕ reports of their own face. This effect was such that observers felt the onscreen face to be their own and that, if the onscreen gaze had moved on its own accord, observers expected their own eyes to move too. The theoretical implications of these findings are discussed.3

“…For example, synchronous visual-tactile stimulation between one's own face and that of another can lead to an illusion of ownership over the other's face, as well as intriguing changes in the perceived similarity of that face to one's own (Sforza, Bufalari, Haggard, & Aglioti, 2010;Tsakiris, 2008). Furthermore, body ownership illusions are no longer restricted to individual body parts; a ''full-body illusion'' has been developed, in which participants feel that they are embodied in a different spatial location to that of their own body (Ehrsson, 2007;Lenggenhager, Tadi, Metzinger, & Blanke, 2007) and even that they have swapped bodies with another person (Petkova & Ehrsson, 2008).…”

The self is one the most important concepts in social cognition and plays a crucial role in determining questions such as which social groups we view ourselves as belonging to and how we relate to others. In the past decade, the self has also become an important topic within cognitive neuroscience with an explosion in the number of studies seeking to understand how different aspects of the self are represented within the brain. In this paper, we first outline the recent research on the neurocognitive basis of the self and highlight a key distinction between two forms of self-representation. The first is the ''bodily'' self, which is thought to be the basis of subjective experience and is grounded in the processing of sensorimotor signals. The second is the ''conceptual'' self, which develops through our interactions of other and is formed of a rich network of associative and semantic information. We then investigate how both the bodily and conceptual self are related to social cognition with an emphasis on how self-representations are involved in the processing and creation of prejudice. We then highlight new research demonstrating that the bodily and conceptual self are both malleable and that this malleability can be harnessed in order to achieve a reduction in social prejudice. In particular, we will outline strong evidence that modulating people's perceptions of the bodily self can lead to changes in attitudes at the conceptual level. We will highlight a series of studies demonstrating that social attitudes towards various social out-groups (e.g. racial groups) can lead to a reduction in prejudice towards that group. Finally, we seek to place these findings in a broader social context by considering how innovations in virtual reality technology can allow experiences of taking on another's identity are likely to become both more commonplace and more convincing in the future and the various opportunities and risks associated with using such technology to reduce prejudice.
