Criminal identification viewed from a different angle: Can a novel interactive lineup procedure improve accuracy?

Perpetrator pose reinstatement—viewing a criminal perpetrator's face in the same pose in which the witness saw him—should enhance face identification performance (e.g., Bruce, 1982). Witnesses likely encode culprits from different angles (left profile, front, right profile), but little research has examined whether pose reinstatement and viewing faces from multiple angles during a lineup improves identification accuracy. Two lineup procedures currently used in practice include photo lineups that show each face in frontal pose, and video lineups that show each face rotating left and right, 
revealing the whole face. We created a novel interactive lineup procedure, wherein witnesses were able to rotate the lineup faces into any pose, and addressed the following questions in our experiments: 1. Does encoding view influence discrimination accuracy? 
 2. Do multiple views at test enhance discrimination accuracy? 
 3. Do subjects reinstate pose and is pose reinstatement associated with accuracy? Our results indicate that learning conditions are important. Participants who viewed the perpetrator from the front at encoding had better discrimination accuracy than subjects who viewed the perpetrator from the profile. Multiple views at test—in video and interactive lineups—can enhance discrimination accuracy. When interacting with the lineup faces, we found that participants spontaneously reinstated the pose in which they had viewed the perpetrator. Pose reinstatement was associated with accuracy. We are continuing this line of work to examine whether interactive lineups can improve accuracy in other circumstances, such as in cross race identifications (i.e., people are worse at recognising faces of a different ethnic/racial background than their own).

Study-test pose improves accuracy
(e.g., Bruce, 1982)
Pose-sensitivity in cortical regions
(e.g., Grill-Spector et al., 1999)
Interactivity improves recognition
(Liu et al., 2007)
Pose less influential (e.g., Logie et al., 1987)
Lineup decision (Bailenson et al., 2008)
Only interact at test (Lui et al., 2007)
