In the abstract the word ‘‘self-location’’ is repeated twice. The second ‘‘self-location’’ was meant to be ‘‘self-identification’’. The correct sentence reads below: This has recently been tested experimentally in healthy subjects showing that integration of multisensory bodily signals from the entire body with respect to the three aspects: self-location, first-person perspective, and self-identification, is crucial for bodily self-consciousness.

People tend to grossly overestimate the size of their mirror-reflected face. Although this overestimation bias is robust, not much is known about its relationships to self-face perception. In two experiments, we investigated the overestimation bias as a function of the presentation of the own face (left-right reversed - as in a mirror - or nonreversed - as in a photograph), the identity of the seen face, and prior exposure to a real mirror. For this we developed a computerized task requiring size estimations of displayed faces. We replicated the observation that people overestimate the size of their mirror-reflected face and showed that the overestimation can be reduced following a brief mirror exposure. We also found that left-right reversal modulates the overestimation bias, depending on the perceived face's identity. These data underline the enhanced familiarity of left-right reversed self-faces and the importance of size perception for understanding mirror reflection processing.

Summary The experience that our body and its parts belong to us and are not those of other people is a key aspect of the ‘self' called body ownership [1]. In six experiments, we have investigated body ownership and its neurophysiology using a tactile illusion [2,3] that disrupts body ownership and tactile sensation robustly, repeatedly, and with no particular apparatus by inducing an illusory feeling of numbness for another person's finger — the ‘numbness illusion' (NI). Our results show that the NI does not depend primarily on visual or motor signals, but on tactile inputs modulating activity in primary somatosensory cortex.
