1. Heather Caspers Lineup Administration

2. Preview • Background • Sequential Superiority Effect • Order effects • Choosers v. Non-choosers • Number of passes

3. Background • Lineup instructions (Malpass & Devine, 1981) • Lindsay and Wells (1985) introduced sequential lineup • Absolute vs. relative responding • Illinois Report • Response

4. Lineup administration • Target-present, target-absent • Possible decisions in target-present: correct: identify target, incorrect: reject lineup or identify foil • Possible decisions in target-absent: correct: reject lineup, incorrect: identify foil • Without replacement (Clark & Davey, 2005; Wells, 1993)

5. Sequential Superiority Effect • Steblay et al., 2001 meta-analysis • Correct rejection higher in sequential lineups • Also examined moderator variables

6. Sequential Superiority Effect • McQuiston-Surrett et al., 2006 meta-analysis • Moderator variables • Target-to-foil shift in both sequential and simultaneous lineups (Clark & Davey, 2005) • Order effects

7. Choosers vs. Non-choosers • Choice as a moderator regarding accuracy-confidence relationship • Sporer, 1993

8. Number of Passes • Sequential superiority effect disappears when participants take more than one pass (MacLin & Phelan, 2007)

9. PC_Eyewitness • Similar to paper-and-pencil administration (MacLin et al., 2005) • Helpful to police officers • Lineup recognition paradigm • Meissner et al., 2005

10. Lineup research • Need to examine factors influencing decision processes surrounding simultaneous and sequential lineups • Signal detection theory explanations (Meissner et al., 2005) • Issues concerning similarity
