Abstract
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
