Eyewitness Identification Study

Study Design: Participants watched a 2-minute video of a burglary, where the burglar's identity changed midway. Half received instructions to intentionally remember (intentional condition), while the other half viewed it incidentally (incidental condition).
Participants: 80 participants (40 men, 40 women), aged 15-65. Majority employed, with some in domestic care or student status.
Video Content: The video depicted a burglary from a student house. Two actors played the burglar, differing in height (1.70m vs. 1.88m) and build.
Testing Procedure: Participants completed a questionnaire about the video, including open-ended questions about the burglar's appearance and seeking awareness of any change. A lineup was presented post-video for identification.
Key Findings:
- Change Blindness: 61% of participants failed to notice the identity change.
- Intentional vs. Incidental: Participants in the intentional condition had significantly higher recall rates and detection rates of the change.
- Awareness and Accuracy: Awareness of the change correlated with better recall and identification accuracy.
- Gender Effect: In the intentional condition, more women than men noticed the change; no gender difference was seen in the incidental condition.
- Statistical Significance: The study utilized chi-square tests and hierarchical log-linear analysis to demonstrate significant differences between conditions.
