-
morphed images of their own face and one of the trust-ees using a staircase procedure. The PSE represented the degree of morphing at which the participant perceived the percentage of self and other in the photo to be the same
It become more difficult for participants to tell when there was more "other" in their picture in the trustworthiness control group. The PSE was higher because the degree that they felt that the pic was equal other and self was more than it actually was. This shows that if you feel someone is trustworthy they begin to look like you

After making both transfer decisions, participants viewed prerecorded videos of the trustees stating how much money they had decided to return to the trustor.

Following the self-recognition task, partici-pants completed the Inclusion of Other in the Self (IOS) scale

participants performed a self-recognition task (Tajadura-Jiménez, Grehl, & Tsakiris, 2012) so we could measure participants’ point of subjective equality (PSE) with each face.
According to the APA, point of subjective equality is "the value of a comparison stimulus that, for a given observer, is equally likely to be judged as higher or lower than that of a standard stimulus." The PSE in this experiment represented "the degree of morphing at which the participant perceived the percentage of self and other in the photo to be the same"

separate gender-matched trustee unknown to the participant
would the results have been significantly different with the opposite gender?
-
we examined how participants’ perception of facial similarity was affected by taking part in a social interaction (trust game) in which the trustee either rewarded or betrayed the participant’s trust
how they tested the variables

If evidence of cooperative intent in others serves as a contextual cue to kinship, then people may perceive another who behaves in a trustworthy way toward them as more physically similar than another who behaves in an untrustworthy way

-
whether the perceived similarity between the self and others can change as a result of such interactions
scientific question
-
