What are the possible causes of mistaken eyewitness identification?
The top 5 causes of eyewitness misidentification are: limitations in human memory, witness stress and anxiety, the fact that witnesses tend to focus more on weapons than a perpetrator’s identity.
How does eyewitness evidence affect a case?
While its role is complex, eyewitness testimony is a crucial part of the criminal justice system. When a legal team presents an eyewitness who can confidently identify the suspect and confirm that they saw them commit a crime, jurors are compelled to believe them.
How often is eyewitness testimony wrong?
Studies have shown that mistaken eyewitness testimony accounts for about half of all wrongful convictions. Researchers at Ohio State University examined hundreds of wrongful convictions and determined that roughly 52 percent of the errors resulted from eyewitness mistakes.
How does eyewitness misidentification lead to wrongful convictions?
Eyewitness misidentification can potentially lead to wrongful convictions in several ways: Misidentifying the perpetrator of a crime, so law enforcement officials lose precious time pursuing the wrong person. Purposefully identifying the wrong person to blame the crime on someone else or providing false testimony.
What are the two main categories of variables that affect eyewitness identification?
Leading social science researchers identify two main categories of variables affecting eyewitness identification: estimator variables and system variables. Estimator variables are those that cannot be controlled by the criminal justice system.
What factors affect a person’s memory and their ability to identify a suspect?
Anxiety levels, visual acuity, sharpness of memory, and environmental factors affect an eyewitness’ ability to recall events. The polygraph and the voice stress analyzer have limitations and legal problems of admissibility; suggestive police identification procedures can also cause eyewitness misidentification.
How can eyewitness testimony be affected by false memory?
Overall, false memories of eyewitnesses are generated either by external misleading information or by internal cognitive processes; false memories may guide police investigations in the wrong direction or cause eyewitnesses to misidentify an innocent person as the perpetrator.
What are two or more lineup strategies that the legal system can make so that mistaken eyewitness identification is less likely?
Ensure that police put in writing why a suspect is believed to be guilty of a specific crime before placing him or her in a lineup. Use a lineup with several people instead of what is known as a showup only featuring a single suspect. Avoid repetition of a lineup with the same suspect and same eyewitness.
What are 2 things that can be done to help improve the validity of eyewitness reporting?
New law enforcement training protocols, standardized procedures for administering lineups, improvements in the handling of eyewitness identification in court, and better data collection and research on eyewitness identification can improve the accuracy of eyewitness identifications.
What are the two areas that influence psychology research?
Therefore the relationship between law and psychology can be viewed as two-way. Psychology research is also influenced by developments in technology, social policy, and the media (e.g. reporting of public outcry over a particular case or event).
