Accuracy of Offender Description = Correlates recollection with real life image. Witness Confidence Level = Relates witness certainty to identification accuracy.</p> Signup and view all the answers

Match each component of the Manson criteria with how it evaluates eyewitness reliability:

<p>Witness opportunity to view perpetrator = Evaluates the length and quality of the witness's view. Level of attention during the crime = Decides level of distraction or concentration of visual details. Correctness of the previous description = Compares with physical attributes of the suspect. Gap Time = Reflects memory loss or alteration.</p> Signup and view all the answers

Match the lineup practices with their intended improvement in identification accuracy:

<p>Inform witness that culprit may not be present = Avoid misleading conclusion suspect is in lineup. Provide unbiased instructions before proceeding = Keep witness devoid external influence. Record witness' confidence immediately after identification = Discourage influenced alterations. Lineup administration happens double-blind = Remove administrator’s unintentional biases.</p> Signup and view all the answers

Match the effect to how it influences an eyewitness recall or identification:

<p>Weapon Focus = Recall of weapon is increased, compromising surrounding details. Misinformation Effect = Incorrect particulars gets melded in one's memory. Source Monitoring = Memory’s origin gets mistaken or forgotten. Unconscious Transfer = Remembering a suspect by mistaking him or her to being offender.</p> Signup and view all the answers

Match the interview methods to its aim in enhancing testimony quality:

Study Notes

  • A person's memory of an event can be altered by misleading information encountered after the event, which is known as the misinformation effect.
  • The source effect occurs when a person misattributes the origin of a memory, recalling a fact but not its source.
  • During a crime, if a witness focuses on a weapon, their ability to recall other details is reduced which exhibits the weapon focus effect.

Accuracy of Lineups vs. Showups

  • Lineups, especially double-blind and sequential lineups, lead to more accurate identifications compared to showups.
  • Showups carry a higher risk of false identification because of suggestiveness.

Relationship Between Eyewitness Confidence and Identification Accuracy

  • Eyewitness confidence and accuracy are related during initial immediate identifications.
  • High-quality viewing conditions and proper lineups also cause relations.
  • Suggestive feedback can alter eyewitness confidence and accuracy.
  • A long delay between the event and identification can also effect eyewitness confidence and accuracy.
  • Poor viewing conditions also impact the relation of confidence and accuracy.

Improving Eyewitness Accuracy

  • Double-blind lineups and sequential lineups can improve eyewitness accuracy.
  • Avoiding confirming feedback and using non-leading instructions ensures accuracy.
  • Accuracy is improved by Avoiding multiple identifications and utilizing cognitive interviews.

Pristine Conditions for Accurate Witness Identification

  • Present only one suspect at a time in a lineup.
  • Ensure the suspect does not stand out in the lineup.
  • Provide unbiased instructions to the witness.
  • Use a double-blind procedure.
  • Obtain an immediate confidence statement from the witness.

Manson Criteria for Evaluating Eyewitness Testimony Accuracy (Manson vs. Braitwaite, 1977)

  • The witness's opportunity to view the suspect is key.
  • The witness's degree of attention is also important.
  • The accuracy of the witness's prior description matters
  • The witness's level of certainty is an important factor.
  • The amount of time elapsed between the event and the identification is also important.
