Abstract

In two field studies, bar tenants (Ns=86 and 190, respectively) were successively approached by confederates C1 and C2 on a night out. Confederate C3 then presented participants with a six-person target-absent or target-present lineup concerning C1 or C2 (immediate test). Several days later, participants viewed a lineup regarding the confederate they had not attempted to identify earlier (C1/C2; delayed test). An immediate compared with a delayed, sober identification test did not increase the risk of a false identification decision. A blood alcohol concentration of 0.06-0.07% best discriminated accurate from inaccurate decisions. Choosers with a blood alcohol concentration
