This study investigated the eyewitness identification of a person who is alleged to be familiar with the witness. Although identification of a familiar person has been believed to be more accurate than that of a stranger, we expected that misidentification of a familiar person as the target would occur, and in such cases, the confidence level of the witnesses would be higher than when correctly rejecting the familiar person. One hundred and seventy-two (172) participants were assigned to four conditions where construct of two-photo lineup and the familiarity of a target's photo were manipulated. First, subjects took an experiment where they rated photos, which were to make them familiar with the faces. Then they participated in another experiment where they saw some familiar faces (shown in the first experiment) and new ones, and took a recognition test which included the rest of familiar faces as distracters. As a result, familiar faces were chosen more often resulting in high hit rate and low correct rejection rate. The findings were discussed from the forensic viewpoint.
