Familiar Recognition

Of the three facial approximations represented by target individuals in the face pool for the unfamiliar trials, two were correctly identified (Table 11.2). Of the seven people familiar with the person represented by FA5, six made correct identifications (86%). Most of these assessors were colleagues of the target who had known her for three years. Of the five people familiar with the person represented by FA1, two made correct identifications (40%). Most of these assessors were friends of the target and had known her for about four years. It is worth noting that a sibling of the target who had known her for almost 20 years did not make a correct identification. Of the four people familiar with the person represented by FA4, none made correct identifications (0%). Most of these assessors had known the target for about two years but again a sibling who had known the target for almost 20 years did not make

Table 11.2 Summary table of recognition responses for people familiar with individuals included in the face pool. Italicized rows indicate responses by people familiar with individuals who were included in the face pool, but who were not used to construct facial approximations. "NI" stands for "no identification response". Note that a total of10 individuals were used overall for familiar tests; some individuals knew more than one individual included in the face pool; one individual correctly identified a facial approximation not represented by a face in the face pool; and two individuals made incorrect identifications of facial approximations not represented by their respective faces in the face pool.

a correct identification. No individuals familiar with the nontarget faces present in the face pool incorrectly identified any of the facial approximations.

Only two (2%) false positive identifications were made out of a total of 95 familiar responses. One assessor in the familiar testing scenario also correctly identified one of the "nontarget" facial approximations (a facial approximation not represented by a target face in the face pool used for unfamiliar testing).
