Document Summary

Lindsay & wells (1985): argued that sequential better than simultaneous, because witnesses making absolute rather than relative judgments of similarity in sequential. Gronlund (2004): found simultaneous-sequential lineup difference due mostly to more conservative response criterion in sequential. Gronlund et al (2012): roc analysis shows sequential lineups never more accurate than simultaneous. Gronlund, wixted & mickes (2014): not clear which procedure which lineup procedure will prove to be generally superior, but roc analysis is the only way to make that determination. Identification characteristics: identification latency, faster = more accuracy (r = -. 20 to -. 40, sweet spot" at 10-15 seconds, how long does it take the witness to say yes this is the person", identification confidence. Problem: correlation between accuracy and confidence is not very high: however: when people are more confident, they do tend to be more accurate. Confidence accuracy calibration (ideal vs. in reality: ideal, in reality. Shows us that we do see a relationship between confidence and accuracy.
