Interactive > passive (Lui et al., 2007)
Motion cues (Buratto et al., 2009)
Diagnostic feature detection (Wixted & Mickes, 2014)
3. Other-race faces are 1.4xmore
likely to misidentified than same-race faces
(Meissner & Brigham, 2001)
50% of identifications made by witnesses are other-race

4. Do interactive lineups enhance accuracy more than
static photo lineups?
Do interactive lineups attenuate the own race bias?

ORB is considered to be
Limited indirect evidence that pose-reinstatement at test can attenuate the ORB.
Data for static lineup
We also fit a signal detection lineup model to these data. That model accounts for all possible ID responses. Assumes detect most familiar person in the lineup, then ID than person if the
