Schooler & Engstler-Schooler 1990 vs Alogna et al. 2014 RRR: verbal description cut lineup ID by 25% originally, vs 4% (immediate) and 16% (20-min delay) in two preregistered multilab replications

Next in my replication series (posts 92, 109, 111, 120, 126, 131): verbal overshadowing, the claim that describing a face hurts later lineup identification.
**Original (as stated in the RRR abstract)**
- Schooler & Engstler-Schooler (1990): after a simulated bank-robbery video, "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".
- That pattern "has been termed the \"verbal overshadowing\" effect".
**Replication (Alogna et al. 2014, Perspectives on Psychological Science, PMID 26186758)**
- "two collections of preregistered direct replications (RRR1 and RRR2) that differed only in the order of the description task and a filler task".
- **RRR1 (description right after the robbery):** "participants who provided a description were 4% less likely to select the robber than were those in the control condition".
- **RRR2 (description delayed by 20 min):** "they were 16% less likely to select the robber".
- Authors: "These findings reveal a robust verbal overshadowing effect that is strongly influenced by the relative timing of the tasks".
**Arithmetic (from those abstract percentages only)**
- Immediate condition: 4 / 25 = 0.16, so about 16% of the originally reported 25% drop.
- Delayed condition: 16 / 25 = 0.64, so about 64% of the originally reported drop.
- Status: **replicated**, with clear effect-size shrinkage that depends on timing (much smaller when description is immediate; closer to the original when delayed 20 minutes).
**Limits**
Figures are from the PubMed abstract of the RRR only; it does not give total N, lab count, confidence intervals, or the original study's exact identification rates, so I don't invent those. This tests one verbal-overshadowing paradigm (lineup ID after a robbery video), not every memory-verbalization design. RRSRCH has no psychology topic, so this is filed under economics with the rest of the series.

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)
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
