From an evolutionary point of view, facial self-resemblance has therefore been ascribed a role as a potential cue for kin recognition, evolved to prevent inbreeding and enhance cooperation among genetic relatives (by means of phenotype matching). This bias toward self-resembling faces may even translate to more favorable prosocial attributions and higher willingness to engage in mutual cooperation (but see for diverging evidence). Most people are inclined to see others similar in physical appearance to themselves as more trustworthy and likable.

The results are discussed with respect to differential (presumably pre-attentive) effects of self-specific vs. Experiment II ( N = 54) produced similar findings using morphs of famous faces, yet showed no impact of mere familiarity on PPI effects (or response time, either).

As indexed both by relative facilitation of startle and faster manual responses, self-resemblance apparently induced deeper processing of facial affect, particularly in happy faces. Both affective modulation and PPI of startle in response to emotional faces was altered by physical similarity to the self. Pictures preceding noise bursts by short SOA inhibited startle (prepulse inhibition, PPI). Manual reaction time was measured in a simple emotion discrimination paradigm. At SOAs of either 300 ms or 3500–4500 ms after picture onset, startle responses were elicited by binaural bursts of white noise (50 ms, 105 dB), and recorded at the orbicularis oculi via EMG. Participants of the first experiment (I) ( N = 39) were presented with morphed faces showing happy, neutral, and fearful expressions which were manipulated to resemble either their own or unknown faces. Here we report two experiments utilizing startle modulation to investigate how the processing of facial expressions of emotion is affected by subtle resemblance to the self as well as to familiar faces. These findings suggest that the brain processes faces in a highly stereotypical manner, and that the deviations from this normative pattern may be related to the risk of mental illness.Facial self-resemblance has been associated with positive emotional evaluations, but this effect may be biased by self-face familiarity. At the individual level, connectivity profiles deviated from the canonical profile, and the magnitude of this deviation related to the presence of psychopathology. At the group level, we found a robust canonical profile of connectivity both across populations and time.
In the present study, we used data obtained with functional magnetic resonance imaging in two cohorts, IMAGEN ( N = 534) and ALSPAC ( N = 465), to investigate - both at group and individual levels - the consistency of the regional profile of functional connectivity across populations (IMAGEN, ALSPAC) and time (Visits 1 to 3 in IMAGEN age 14 to 22 years). An individual's profile of functional connectivity across a face network can be shaped by common organizing principles, stable individual traits, and time-varying mental states. The ability to extract cues from faces is fundamental for social animals, including humans.
