The verbal facilitation effect: re-reading person descriptions as a system variable to improve identification...

Area of Science:

• Cognitive Psychology
• Forensic Psychology
• Eyewitness Memory

Background:

• The verbal overshadowing effect (VOE) suggests describing a face can impair later identification.
• Replication of the VOE has proven difficult, questioning its robustness.
• Context reinstatement is a known memory enhancement technique.

Purpose of the Study:

• To investigate if re-reading a witness's own description can reverse the verbal overshadowing effect.
• To determine if context reinstatement through self-description review enhances eyewitness identification accuracy.
• To explore the relationship between description quality and identification performance.

Main Methods:

• 208 participants watched a video and performed identification tasks after varying delays (2 days, 5 weeks).
• Conditions included a control group, description-only group, and description-plus-re-reading group.
• Participants identified perpetrators from target-present or target-absent lineups.

Main Results:

• Identification accuracy was significantly higher (85.0%) when participants re-read their descriptions compared to controls (62.5%).
• Accuracy correlated positively with the quality of the initial description.
• Receiver operating characteristic (ROC) analyses confirmed improved recognition performance, not response bias shifts.

Conclusions:

• Re-reading self-generated descriptions can facilitate, rather than impair, eyewitness identification accuracy.
• Context reinstatement via self-description review appears to be a viable method to enhance eyewitness memory.
• Findings suggest a potential verbal facilitation effect (VFE) under specific conditions.
