For each participant (20 anorexics, 20 healthy controls) we built personalized avatars that reproduced their own body size, shape, and verisimilar increases and losses of their original weight. Body overestimation and dissatisfaction were measured by asking participants to choose the avatar that best resembled their real and ideal body. Results show higher body dissatisfaction in AN, caused by the desire of a thinner body, and no body-size overestimation. Interpersonal multisensory stimulation (IMS) was then applied on the avatar reproducing participant's perceived body, and on the two avatars which reproduced increases and losses of 15% of it, all presented with a first-person perspective (1PP). Embodiment was stronger after synchronous IMS in both groups, but did not reduce BID in participants with AN. Interestingly, anorexics reported more negative emotions after embodying the fattest avatar, which scaled with symptoms severity. Overall, our findings suggest that the cognitive-emotional, more than the perceptual component of BID is severely altered in AN and that perspective (1PP vs. 3PP) from which a body is evaluated may play a crucial role. Future research and clinical trials might take advantage of virtual reality to reduce the emotional distress related to body dissatisfaction.</dcterms:abstract> <dc:creator>Tieri, Gaetano</dc:creator> <dc:contributor>Dazzi, Federico</dc:contributor> <dcterms:rights rdf:resource="http://creativecommons.org/licenses/by/4.0/"/> <dc:creator>Provenzano, Luca</dc:creator> <dc:contributor>Loriedo, Camillo</dc:contributor> <dc:creator>Bufalari, Ilaria</dc:creator> <dc:creator>Lenggenhager, Bigna</dc:creator> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/57171/3/Provenzano_2-xoqwxrz1egtj7.pdf"/> <dc:creator>Porciello, Giuseppina</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Porciello, Giuseppina</dc:contributor> <dc:creator>Dazzi, Federico</dc:creator> <dc:contributor>Ciccarone, Sofia</dc:contributor> </rdf:Description> </rdf:RDF>
