Study Notes
- Concerns the misinformation effect, source effect, weapon focus effect, accuracy from lineups vs showups, relationship between eyewitness confidence and identification accuracy, ways to improve eyewitness accuracy, pristine conditions for accurate witness identification, and the Manson criteria for evaluating eyewitness testimony accuracy.
Psychological Effects on Memory
- Misinformation effect: Memory of an event is altered by misleading information introduced after the event.
- Source effect: Misattributing the source of a memory, remembering a fact but not where it was learned.
- Weapon focus effect: When a weapon is present during a crime, the witness focuses on the weapon, reducing their ability to recall other details.
Lineups Vs. Showups
- Lineups lead to more accurate identification when conducted fairly using double-blind and sequential methods.
- Showups have a higher risk of false identification due to suggestiveness.
Eyewitness Confidence and Identification Accuracy: Related Conditions
- Related: Initial immediate identifications, high-quality viewing conditions, and proper lineups.
- Accuracy of eyewitness identification is related to their confidence at initial identification.
- High-quality viewing conditions aid in more accurate and confident eyewitness identifications
- Proper lineups, designed to reduce bias, contribute to the relationship between confidence and accuracy.
Eyewitness Confidence and Identification Accuracy: Unrelated Conditions
- Confidence is not related: After suggestive feedback, long time between event and identification, poor viewing conditions
- Suggestive feedback can inflate confidence without improving accuracy.
- A long time between the event and identification diminishes the reliability of confidence.
- Poor viewing conditions undermine both accuracy and the reliability of confidence.
Improving Eyewitness Accuracy
- Employ double-blind lineups
- Use sequential lineups (one after another).
- Avoid confirming feedback to prevent inflated confidence.
- Avoid leading instructions to minimize bias.
- Avoid multiple identifications
- Employ cognitive interviews to enhance memory recall.
Pristine Conditions for Accurate Witness Identification
- Present only one suspect at a time in the lineup.
- Construct the lineup so the suspect does not stand out.
- Provide unbiased instructions to the witness.
- Use a double-blind procedure.
- Obtain an immediate confidence statement from the witness.
Manson Criteria (Manson vs. Braitwaite, 1977)
- Opportunity to view the suspect: the amount of time and clarity of the witness's view.
- Degree of attention: The witness's focus on the suspect during the event.
- Accuracy of prior description: How well the witness's initial description matches the suspect.
- Level of certainty: The witness's confidence in the identification.
- Time elapsed: The duration between the event and the identification.
