“…Differences between self and familiar faces were evident in ROT areas, which are often active during facial processing (Alzueta et al., 2020; Iidaka, 2014) and might thereby facilitate self‐face recognition. Although the effects of self‐face processing on P200 have been observed in a number of previous studies (e.g., Caharel et al., 2007; Estudillo et al., 2018; Keyes et al., 2010; Parketny et al., 2015; Tanaka et al., 2006), they have often been overlooked. Indeed, only recently have some authors highlighted the importance of the P200 component for self‐face processing (Alzueta et al., 2019; Estudillo, 2017).…”

The upside‐down self: One's own face recognition is affected by inversion

One's own face is recognized more efficiently than any other face, although the neural mechanisms underlying this phenomenon remain poorly understood. Considering the extensive visual experience that we have with our own face, some authors have proposed that self‐face recognition involves a more analytical perceptual strategy (i.e., based on face features) than other familiar faces, which are commonly processed holistically (i.e., as a whole). However, this hypothesis has not yet been tested with brain activity data. In the present study, we employed an inversion paradigm combined with event‐related potential (ERP) recordings to investigate whether the self‐face is processed more analytically. Sixteen healthy participants were asked to identify their own face and a familiar face regardless of its orientation, which could either be upright or inverted. ERP analysis revealed an enhanced amplitude and a delayed latency for the N170 component when faces were presented in an inverted orientation. Critically, both the self and a familiar face were equally vulnerable to the inversion effect, suggesting that the self‐face is not processed more analytically than a familiar face. In addition, we replicated the recent finding that the attention‐related P200 component is a specific neural index of self‐face recognition. Overall, our results suggest that the advantage for self‐face processing might be better explained by the engagement of self‐related attentional mechanisms than by the use of a more analytical visuoperceptual strategy.

“…Larger N170 amplitudes for inverted faces reflect a disruption of configural processing and a preponderance of featural processing. The N170 is modulated by "selfinformation," and more negative for own relative to other faces [e.g., (40,41)]. (3) The occipito-temporal P200 occurs about 200-250 ms poststimulus, has been related to the perceived typicality of a face [e.g., (40,42,43)], and is larger for less distinctive (i.e., more typical) faces.…”

Background: Body dysmorphic disorder (BDD) is characterized by an excessive preoccupation with one or more perceived flaws in one's own appearance. Previous studies provided evidence for deficits in configural and holistic processing in BDD. Preliminary evidence suggests abnormalities at an early stage of visual processing. The present study is the first examining early neurocognitive perception of the own face in BDD by using electroencephalography (EEG). We investigated the face inversion effect, in which inverted (upside-down) faces are disproportionately poorly processed compared to upright faces. This effect reflects a disruption of configural and holistic processing, and in consequence a preponderance of featural face processing. Methods:We recorded face-sensitive event-related potentials (ERPs) in 16 BDD patients and 16 healthy controls, all unmedicated. Participants viewed upright and inverted (upside-down) images of their own face and an unfamiliar other face, each in two facial emotional expressions (neutral vs. smiling). We calculated the early ERP components P100, N170, P200, N250, and the late positive component (LPC), and compared amplitudes among both groups.Results: In the early P100, no face inversion effects were found in both groups. In the N170, both groups exhibited the common face inversion effects, with significantly larger N170 amplitudes for inverted than upright faces. In the P200, both groups exhibited larger inversion effects to other (relative to own) faces, with larger P200 amplitudes for other upright than inverted faces. In the N250, no significant group differences were found in face processing. In the LPC, both groups exhibited larger inversion effects to other (relative to own) faces, with larger LPC amplitudes for other inverted than upright faces. These overall patterns appeared to be comparable for both groups. Smaller inversion effects to own (relative to other) faces were observed in none of these components in BDD, relative to controls. Conclusions:The findings suggest no evidence for abnormalities at all levels of early face processing in our observed sample of BDD patients. Further research should investigate the neural substrates underlying BDD symptomatology.Keywords: body dysmorphic disorder, own-face perception, face inversion effect, event-related potentials, electroencephalography Ritter et al.

“…ERP components linked with early visual processing (N170, P2) and attention (N2PC, SPCN) show a modulation specific to self-face supporting the automatic capture of self-face ( Alzueta et al., 2020 ; Keyes et al., 2010 ; Wójcik et al., 2018 ). Interestingly, these modulations are also present for faces for which have been synchronized with self-face to induce enfacement illusion ( Estudillo et al., 2018 ). Furthermore, they do not find similar modulation for other familiar faces, hinting toward a unique ability of self-face to capture attention.…”

Earlier work on self-face processing has reported a bias in the processing of self-face result in faster response to self-face in comparison to other familiar and unfamiliar faces (termed as self-face advantage or SFA). Even though most studies agree that the SFA occurs due to an attentional bias, there is little agreement regarding the stage at which it occurs. While a large number of studies show self-face influencing processing later at disengagement stage, early event-related potential components show differential activity for the self-face suggesting that SFA occurs early. We address this contradiction using a cueless temporal order judgment task that allows us to investigate early perceptual processing, while bias due to top-down expectation is controlled. A greater shift in point of subjective simultaneity for self-face would indicate a greater processing advantage at early perceptual stage. With help of two experiments, we show an early perceptual advantage for self-face, compared to both a friend’s face and an unfamiliar face (Experiment 1). This advantage is present even when the effect of criterion shift is minimized (Experiment 2). Interestingly, the magnitude of advantage is similar for self-friend and self-unfamiliar pair. The evidence from the two experiments suggests early capture of attention as a likely reason for the SFA, which is present for the self-face but not for other familiar faces.
