Running Head: LINEUPS FOR SUSPECTS WITH DISTINCTIVE FEATURES Creating Fair Lineups for Suspects with Distinctive Features

In their descriptions, eyewitneVVHV RIWHQ UHIHU WR D FXOSULW¶V GLVWLQFWLYH IDFLDO IHDWXUHV %XW LQ D police lineup, to select the only member with the distinctive feature is both unfair to the suspect and provides the police with no further information. To provide information over and above the presence of the distinctive feature, the distinctive feature should either be replicated across foils or concealed on the target. In the present experiments, replication produced more correct identifications in target-present lineups ±without increasing the incorrect identification of foils in target-absent line ups± than did concealment. This pattern ±and only this pattern± is predicted by the hybrid-similarity model of recognition.
