It has been a tough one, but finally it is published! Our paper Multisensory stimulation modulates perceptual and post perceptual face representations: Evidence from event‐related potentials is published now in the European Journal of Neuroscience. In this paper we explore the cognitive locus of the process of updating the own face representation. Our own face is not a static stimulus, but it changes as consequence of aging, grooming activities, etc. So to accommodate these changes our own face representation need to be constantly updated. Previous research has shown that multisensory signals underlies this process of updating the own face representation, that is we combine information from different senses, (e.g., vision, proprioception, touch signals, etc.). This makes sense, as when we see our own face in the mirror, we don't see a static an image, but an image but it moves when we move and we feel that it is touched when this image is touched.
A way to simulate in the lab this process of updating the own face representation is with the enfacement paradigm (see Tsakiris, 2008). In this paradigm, observers are stroke either in synchrony or in asynchrony with an onscreen face. Thus, the synchronous stimulation condition is highly similar to the process of seeing the own face in a mirror. After a few seconds of synchronous, but not asynchronous stimulation, observers feel that the onscreen face is actually the own face. In our experiments, after a stimulation stage, observers were presented with the synchronous stimulated face, the asynchronous stimulated face, the observer's own face, a couple of filler faces, and a to-be-detected face. We found that synchronous stimulation modulates ERP components related to perceptual (i.e., N170) and post-perceptual (i.e., P200) face processing, but not later components related to identity processing (i.e, N250) or emotional salience (i.e., P300) of the face.
