Reevaluating the role of verbalization of faces for composite production: Descriptions of offenders matter!

Standard forensic practice necessitates that a witness describes an offender's face prior to constructing a visual likeness, a facial composite. However, describing a face can interfere with face recognition, although a delay between description and recognition theoretically should alleviate this issue. In Experiment 1, participants produced a free recall description either 3-4 hr or 2 days after intentionally or incidentally encoding a target face, and then constructed a composite using a modern "feature" system immediately or after 30 min. Unexpectedly, correct naming of composites significantly reduced following the 30-min delay between description and construction for targets encoded 2 days previously. In Experiment 2, participants in these conditions gave descriptions that were better matched to their targets by independent judges, a result which suggests that the 30-min delay actually impairs access to details of recalled descriptions that are valuable for composite effectiveness. Experiment 3 found the detrimental effect of description delay extended to composites constructed from a "holistic" face production system. The results have real-world but counterintuitive implications for witnesses who construct a face 1 or 2 days after a crime: After having recalled the face to a practitioner, an appreciable delay (here, 30 min) should be avoided before starting face construction.
