Eyewitness Identification Data from US and UK Lineup Procedures

2249 participants watched a crime video and were tested using either a US-style six-person simultaneous photo lineup or a UK-style nine-person sequential video lineup. The dataset supports analysis of discriminability and reliability in eyewitness identification procedures.

Use Cases

• Compare discriminability metrics between the US six-person simultaneous photo lineup and the UK nine-person sequential video lineup procedures.
• Analyze confidence-accuracy characteristics to assess the reliability of eyewitness identifications across the two procedural formats.
• Investigate the relationship between participant responses and the specific lineup type (simultaneous vs. sequential) used in the test.

Strengths

• Data from a controlled experiment involving 2249 participants.
• Directly compares two distinct real-world lineup procedures used in the US and UK.
• Focuses on two key analytical metrics: discriminability and reliability.

Limitations

• The dataset does not pinpoint the specific reason for performance differences between the two procedures.
• Sample size of 2249 participants may limit granular subgroup analyses.
• Experimental setting may not fully capture the stress and complexity of real-world eyewitness scenarios.
