Strengthening human-centered face recognition in law enforcement: Combining the Zurich face cognition test with the holistic cognitive interview

In the area of security, human cognition remains essential for face recognition despite advancements in technology. Law enforcement agencies (LEAs) are interested in harnessing these abilities, as recognizing people is a fundamental aspect of their work. We conducted two studies to support integrating human face recognition skills into police work. In study 1, we developed the Zurich Face Cognition Test (ZFCT), a self-assessment tool that reliably measures the face cognition abilities of police officers with authentic police material. Our approach is complementary to the identification of super-recognizers. In study 2, we evaluated the Holistic Cognitive Interview (HCI), a method successfully applied in the UK to recognize facial composites better. Our results indicate that the HCI provides an effective strategy for police officers to memorize images of unfamiliar faces more effectively, for example, for better recognition of wanted or missing persons.
