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

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

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)

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

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

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

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

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

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
