Q

Eyewitness Testimony

A

o Juries rely heavily on eyewitness testimony
o Accuracy of eye-witness identification depends on viewing conditions when the crime was committed
o Most jurors believe witnesses can correctly identify the criminal, even when viewing conditions are poor
o STUDY: Wells et al. (1998)
- Examined 40 cases in which DNA obtained after conviction showed person was innocent
- In 36 cases, eyewitnesses had put the person at the scene of the crime

Q

Acquisition

A

o Process by which people notice and pay attention to information in the environment
o People can acquire only a subset of the information available in the environment
o Witnesses overestimate the length of time an event takes place
o Study: review of RCMP fraud and robbery crimes
- Looked at 3 characteristics of perpetrator: facial hair, hair colour, line-up
- Eyewitness were really good at telling if had facial hair; victim was basically chance
- Chance for all other categories…
- Victim; stress and fear therefore visual and attentional field narrowed so we’re processing less…same for witness, but not at same level of victim
o Accuracy decreased when weapon is present
o Victims focus more on weapon than on physical features of perpetrator
o When gun involved, accuracy goes way down
o Accuracy influence by: time, viewing conditions and victim
o We notice what fits our schema – remember familiar things more readily than unfamiliar things
- Better at recognizing faces from our own race: own race bias (or more contact with…)

Q

Storage

A

o Process by which people hold in memory the information they have acquired from the environment
o Reconstructive memory: memories for an event become distorted by information encountered after the event has occurred
o Source errors – start to forget where you got the information from
o Even the way the questions are phrased can mislead us

Q

Retrieval

A

o Process by which stored information is brought forward
o Accuracy better with a 6-person lineup than on an individual basis
- Tendency to choose person who most resembles the perp, even if resemblance is small
- People who “know” right away tend to be more correct that those who need to compare faces
- Accuracy decreased when required to put what you’ve seen into words – forced to focus on specific details rather than big picture

Ways to improve lineup results

A
  • Have everyone resemble the perp
  • Tell witness the perp may or not be in lineup

Q

Witness confidence

A

o People are more apt to believe witnesses who are confident about what they saw

Detecting lies

A
  • No one is better than another at detecting lies (people often think authority figures are good at that, but they have chance levels)

Q

Improving eyewitness testimony - recovered memories

A
  • Recollections of an event, such as sexual abuse, that have been forgotten or repressed

Q

Jurors

A
  • Only understand about 60% of instructions they are given
  • Jurors are sometimes biased by pretrial publicity, even when they consciously try not to be
  • Emotional publicity that arouses public passions, such as lurid details about a murder, creates the most bias
  • During the trial jurors attempt to make sense of the testimony, and often decide on one story that explains most of the evidence
  • Then they try to fit the story to the possible verdicts they are allowed to render
  • If one of the verdicts fits their preferred story, they are likely to vote to convict on that charge
17
Q

Two ways to present evidence

A
  • Story order: evidence is presented in the sequence in which events occurred
  • Witness order: witnesses are presented in the sequence they think will have the greatest impact
  • Story is most influential
18
Q

Jurors - during deliberations

A
  • Jurors with minority views are often pressured into conforming to the view of the majority
  • Dissenters may not sway the verdict but can reduce the severity of the penalty
19
Q

Deterrence theory

A

People refrain from criminal activity because of the threat of legal punishment, as long as the punishment is perceived as:

  • relatively severe
  • swift
  • certain
20
Q

Procedural justice

A
  • More likely to obey the law if sense of procedural justice is high – believe that procedures used to determine guilt or innocence are fair
