Figure 1. The target segment of the study face and the target segment of the (correct) test face were taken from two different images of the same person on both congruent and incongruent trials. On congruent trials the distractor segment of the correct test face was also matched in identity to the distractor segment of the study face. However, on incongruent trials, the distractor segment of the (correct) test face was not matched in identity to the distractor region of the study face. Specifically, the target region in both the study face and the (correct) test faces are from Person A. On the congruent trial, the non-target region of both the study and (correct) test face are from Person B. However, in the incongruent trial, while the target regions are matched in identity (Person A), the non-target regions of the study face and the (correct) test face are from two different identities (Persons A and C).
