Trying to remember something now typically improves your ability to remember it later. However, after watching a video of a simulated bank robbery, participants who verbally described the robber were 25% worse at identifying the robber in a lineup than were participants who instead listed U.S. states and capitals—this has been termed the “verbal overshadowing” effect (Schooler & Engstler-Schooler, 1990). More recent studies suggested that this effect might be substantially smaller than first reported. Given uncertainty about the effect size, the influence of this finding in the memory literature, and its practical importance for police procedures, we conducted two collections of preregistered direct replications (RRR1 and RRR2) that differed only in the order of the description task and a filler task. In RRR1, when the description task immediately followed the robbery, participants who provided a description were 4% less likely to select the robber than were those in the control condition. In RRR2, when the description was delayed by 20 min, they were 16% less likely to select the robber. These findings reveal a robust verbal overshadowing effect that is strongly influenced by the relative timing of the tasks. The discussion considers further implications of these replications for our understanding of verbal overshadowing.
Eyewitness memory can be negatively influenced by the presence of a weapon during a crime. We investigated the potential impact of weapon presence on the confidence–accuracy relationship. Additionally, we tested a concealed weapon condition, as it is common for criminals to verbally threaten a victim with a weapon, despite not showing one during a crime. In support of the weapon focus effect (WFE), correct identifications were lower, and false identifications were higher, for participants who saw the weapon. The concealed weapon did not create a WFE, even though the perpetrator attempted to draw attention to the gun in his pocket, and participants reported that he had a gun. Calibration analyses revealed that weapon presence, whether visible or concealed, did not negatively impact the confidence–accuracy relationship. In fact, participants were best calibrated when the weapon was clearly visible. We discuss implications of these findings for police and the criminal justice system.
