Identifying the Perpetrator Flashcards
As emphasised by Zajac, we are not very good at identifying strangers, especially when they are another ethnicity. True or false?
True
Encoding and storage are ____ variables:
Estimator
(Variables that affect how an eyewitness remembers details about a crime or perpetrator.)
Retrieval is a ____ variable.
System
(Variables that affect how evidence is elicited from eyewitnesses, by the criminal justice system)
The phenomenon in which we fail to distinguish between other ethnicities is called:
Cross-race bias
Age and ethnicity are examples of:
Stable witness factors
Factors about a person that can change from day to day, such as alcohol consumption or tiredness, are called:
Malleable witness factors
Our ability to remember more distinctive faces when identifying a perpetrator is an example of a:
Stable target factor
(Distinctive faces are not easily changed)
A perpetrator using disguises to avoid identification is an example of a:
Malleable target factor
(Disguises are an easy and resourceful way for perpetrators to change their appearance and avoid being identified.)
According to Shepherd & Ellis (1996), eyewitnesses are most likely to describe which feature about a person?
Hairstyles.
(This can be problematic when identifying a perpetrator as hairstyles are not stable and can be frequently changed.)
According to Shepherd & Ellis (1996), the eyes, nose and face shape are more or less likely to be described in eyewitness interviews?
Less
(This is problematic because they are stable factors and are not likely to change, compared to features like hairstyles, which are most identified by eyewitnesses but also most likely to change.)
Light levels, visibility, the presence of a weapon and the seriousness of a crime are all ____ factors:
Environmental
Delay, misinformation and verbal overshadowing are all examples of ____ factors:
Post-event
Eyewitnesses are not likely to do well at facial recognition tasks after verbally describing what someone looks like. This phenomenon is known as:
Verbal overshadowing
The way eye witness evidence is elicited, thus making them more likely to misidentify someone, demonstrates a problem with system or estimator variables?
System variables
Verbal descriptions, facial composites, mugshot books and line-ups are all examples of ___ variables:
System.
