Automatic recognition, elimination strategy and familiarity feeling: Cognitive processes predict accuracy from lineup...

Area of Science:

• Cognitive Psychology
• Forensic Psychology
• Criminal Justice

Background:

• Accurate suspect identification is crucial for effective criminal investigations.
• Eyewitness decision-making during lineup identification involves distinct cognitive processes.
• Previous research has identified 'automatic recognition' and 'elimination' as key strategies.

Purpose of the Study:

• To examine the relationship between eyewitness decision strategies and identification accuracy.
• To investigate the role of a familiarity-based factor in lineup identification.
• To validate a refined questionnaire for measuring cognitive processes in eyewitness identification.

Main Methods:

• Two experiments were conducted in France and South Africa.
• A modified Retrospective Self Awareness (RSA) interview method was used to create questionnaires.
• Factor analysis identified three common factors: automatic recognition, elimination strategy, and familiarity.

Main Results:

• Witnesses reporting a familiarity feeling were less likely to make correct identification decisions.
• Witnesses reporting the use of an 'elimination strategy' were less likely to make correct decisions.
• Witnesses reporting 'automatic recognition' were more likely to make correct identification decisions.

Conclusions:

• The 'automatic recognition' strategy is associated with higher accuracy in suspect identification.
• Reliance on familiarity or elimination strategies can decrease the likelihood of correct eyewitness identification.
• Findings highlight the importance of understanding cognitive processes in eyewitness testimony.
