Computerized facial composites from memory were ineffective. Even familiar viewers could not recognize individuals from these composites, questioning their use in criminal investigations.

Area of Science:

  • Cognitive Psychology
  • Forensic Science

Background:

  • Facial composites are used to identify suspects.
  • Computerized systems aim to improve composite accuracy.

Purpose of the Study:

  • To evaluate the effectiveness of the Mac-a-Mug Pro facial composite system.
  • To determine if facial composites aid recognition in identification tasks.

Main Methods:

  • Study 1: Participants created composites from memory; recognition was tested with known/unknown individuals.
  • Study 2: Witnesses attempted to identify targets from photo lineups containing composites.

Main Results:

  • Composites were not recognized by viewers, even when the depicted individuals were known.
  • Composite quality and familiarity did not predict recognition accuracy.

  • Witnesses failed to identify targets from composite-based photo lineups.

    • Conclusions:

    • The Mac-a-Mug Pro system showed limited effectiveness in producing recognizable facial composites.
    • The findings raise concerns about the utility of such systems in real-world forensic applications.
