Interactive versus Photo and Video Lineups.
For front encoding, for any false ID rate, simultaneous interactive lineups enhanced the correct ID rate of target faces by 35% and 27% compared to sequential video and simultaneous photo lineups, respectively. The ROC analysis found better discriminability for simultaneous interactive than simultaneous photo lineups, though this was not statistically significant in the modeling results (For profile-encoding, for any possible false identification rate, interactive lineups enhanced the target correct identification rate by 75% and 60% compared to simultaneous photo and video lineups, respectively. This suggests discriminability is enhanced for simultaneous interactive witnesses because they can actively explore and compare faces in the same pose that they were encoded, thereby increasing the availability and use of proportionally more diagnostic features. Further research is needed to examine the relative contributions of active exploration and pose reinstatement in enhancing discriminability. This work should also incorporate independent measures of participant motivation and engagement to further investigate any potential biases that might be introduced by the exclusion of noninteracting participants from the analysis.
