(62 cards)
What did the Supreme Court rule regarding DNA evidence for convicted offenders?
States are not required to make DNA evidence available to convicted offenders, leaving many wrongly convicted without a way to prove their innocence.
What is the leading cause of wrongful convictions?
Eyewitness errors are the leading cause, accounting for 70% of wrongful convictions from mistaken identifications.
What is confirmation bias in the context of eyewitness identification?
Confirmation bias leads police to stop investigating once there is a tentative identification.
What conditions make mistaken identifications common?
Conditions such as low light, quick events, or brief encounters contribute to mistaken identifications.
What is the weapon focus effect?
The weapon focus effect is the failure to notice other stimuli when a gun is present.
How does heightened arousal affect memory encoding?
Heightened arousal does not always enhance encoding; extreme stress can lead to incomplete or inaccurate information encoding.
What is a significant factor affecting memory loss after a crime?
Memory loss is rapid, and time passing between the crime and police questioning can exacerbate this.
How can post-event information affect memory?
Post-event information can alter the memory of the original event.
What is unconscious transference?
Unconscious transference is the generation of a memory based on past interactions with a suspect, leading to confusion between innocent and guilty parties.
What are system variables in eyewitness accuracy?
System variables refer to how the lineup is conducted.
What are estimator variables in eyewitness accuracy?
Estimator variables are factors beyond the control of the justice system, such as lighting conditions at the time of the crime.
How does decision-making speed affect eyewitness accuracy?
Witnesses who make decisions more quickly tend to be more accurate than those who take longer.
What is a cognitive interview?
Cognitive interviews can generate substantial increases in correct recall but may also produce a small increase in incorrect details.
What should be communicated to eyewitnesses during a lineup?
Eyewitnesses should be told that the perpetrator may or may not be present in the lineup.
What is relative judgment in eyewitness identification?
Relative judgment occurs when a witness selects whoever looks most like the perpetrator, often used when memory is weak.
Why should lineup administrators be blind to the suspect’s identity?
Lineup administrators should be blind to prevent any influence on the eyewitness’s decision.
What common misconception exists about eyewitness accuracy?
There is a tendency to overestimate the accuracy of eyewitnesses.
What role can expert witnesses play in court regarding eyewitness testimony?
Expert witnesses can provide information to the judge and jury about the psychological evidence related to eyewitness identification.
How accurate are children as eyewitnesses?
Children aged 5 can make reasonably reliable identifications from lineups, but they are generally less accurate than adults when the culprit is absent.
What is important in investigative interviews with children?
No suggestive questions should be asked, and structured questioning protocols should be used.
What is a notable finding regarding the credibility of child witnesses?
Courts are more likely to believe an 8-year-old than a 12-year-old in sex abuse cases.
What is a common theme in reports of repressed and recovered memories?
Most reports involve individuals recalling experiences of sexual or physical abuse during childhood after years of repression.
What do researchers question about recovered memories?
Researchers often question the validity of memories that resurface years after the alleged incidents, especially after therapy.
What can suggest about spontaneously recovered memories?
Memories recovered spontaneously can be more easily corroborated, indicating they may be genuine.
