Absolute-judgment models better predict eyewitness decision-making than do relative-judgment models.

When presented with a lineup, the witness is tasked with identifying the culprit or indicating that the culprit is not present. The witness then qualifies the decision with a confidence judgment. But how do witnesses go about making these decisions and judgments? According to absolute-judgment models, witnesses determine which lineup member provides the strongest match to memory and base their identification decision and confidence judgment on the absolute strength of this MAX lineup member.

Comparing witness performance in the field versus the lab: How real-world conditions affect eyewitness decision-making.

Objective: This field-simulation experiment was designed to compare eyewitness performance when conducting show ups and lineups under field versus laboratory conditions.

Hypotheses: We expected to replicate the findings from previous field-simulation experiments showing overconfidence in show up identifications made under field but not lab conditions, and further predicted that under field conditions, high-confidence identifications are more likely to be correct when using lineups compared with show ups. It was also expected that field conditions would lead witnesses to lower their criterion for choosing with show ups, but we did not know how field conditions would affect lineup decision-making.
