Q

Where can a forensic psychologist work?

A

A court room: providing assessments, reports and being an expert witness or giving an expert opinion

A police station: developing profiles for suspects

The treatment room (prisons, special organisations- CPS): assess and treat victims, witnesses and criminals

The research lab: conduct research such as witness studies, jury behaviour and psychology of the courtroom

Remember at least two of the above

Also: forensic mental health units, correctional institutions (prisons), law courts, children protection services, sexual offenders treatment services, domestic violence programs, police, universities, research organisations

Q

What is an intimacy-seeking stalker’s typical behaviour?

A

They respond to loneliness and try to establish a close relationship with someone in an inappropriate way. They would begin stalking after a brief social encounter and can stalk their victim for a very long time. They don’t see a court order as something that could stop them from stalking and see the punishment for stalking as a ‘price to pay’.

Q

What is criminal profiling and criminal profiles based on?

A

They are based on the assumption that criminals will leave clues to their identity at a crime scene.

The offender’s (criminal) behaviour at the crime scene reflects something about them as a person.

Q

When is criminal profiling used?

A

It is used once a crime has occurred but when we don’t really know who committed the crime. It is created using the clues left behind.

It helps the police to identify potential suspects as well as narrow the list of suspects.

It is usually used for mass murderers (for people who kill more than one person: serial murderer/serial killer)

44
Q

What distinguishes a spree murderer?

A

When the killer murders people at two or more locations.

45
Q

What are the types of criminal profiling methods?

A

There are three types (only need to know 1- the third one)

1- Crime scene analysis (made by FBI in USA)
2- Investigative Psychology (made by Dr David Carter in the UK)
3- Behavioural evidence analysis (made by Brent Turvey)

46
Q

What is inductive criminal profiling?

A

Comparing known information about the crime under investigation with other similar crimes. Uses this comparison to decide on the type of offender who is most likely responsible.

47
Q

What is deductive criminal profiling?

A

Using information about the crime to draw specific conclusions about the type of offender responsible. Also know as Behavioural Evidence Analysis (BEA)

48
Q

Using the example below, what is the signature aspect and behaviour?

Example: if an offender does not like blondes because as a child they were bullied by a popular blond girl, they might kill their victim (who is blind) and then die their hair brunette.

A

Aspect: revenge and anger towards girls with blond hair

Behaviour: dying the girls hair brown after killing her

50
Q

What does BEA stand for?

A

Behavioural Evidence Analysis

51
Q

What is the first step for BEA? Explain

A

Evidence:
Where you analyse the forensic evidence using physical evidence such as: crime scene photos, sketches and videos, autopsy reports, videos or photos, bloodstream patterns- directions of flow/gush and amount of blood loss, bullet wounds- direction of entry, gunpowder burns (shows if shot at from too close a distance) and hair fibres, fingerprints and DNA test results.

Called equivocal forensic analysis because it’s important for investigators to consider the fact that the evidence can be interpreted in more than one way.

52
Q

What is the second step for BEA? Explain.

A

Victimology/Victim’s characteristics:
Looking at the victims personality, age, physical build and marital status- it helps to create an as accurate a ‘picture’ of the victim as possible.

Determine how? when? why? the victim was chosen- gives a clue to the identity of the offender

53
Q

What is an example of using victimology to help find the offender?

A

If an offender carries the victim away from the spot he/she killed the victim it suggests the offender it either muscular or has a heavy build or an accomplice.

If there was no struggle it might mean that the victim knows the offender or that they had good social skills to convince the victim to accompany them.

54
Q

What is the third step for BEA? Explain.

A

Scene (crime scene):
Analyse the crime scene characteristics using evidence and victimology (step one and two). To determine where? and the number of crime scenes. Also determines if the crime scene had a special meaning to the the criminal- helps provide clues to the offender’s identity.

Primary crime scene: place where majority of interaction between victim and offender takes place.

55
Q

What is the fourth step for BEA? Explain.

A

Profile (criminal profile):
Develop a criminal profile using physiological and psychological characteristics. It is prepared using information from steps one, two and three.

The profile is given to detectives working on the case so they can cross check it with their list of suspects. It can produce more suspects or eliminate suspects that are under investigation.

56
Q

What is the fifth step for BEA? Explain.

A

Apprehension/Arrest:
This only occurs in about 50% of cases. The suspect is identified and he or she is interviewed, investigated and compared to the profile. If the police believe this person is the perpetrator they get a warrant to arrest them and it is then followed by a trial (arrested then taken to trial) with expert witnesses- forensic psychologists and other forensic experts, including the people involved in step one.

57
Q

What is a warrant?

A

A document issued by a legal or government official authorising the police or another body to make an arrest, search premises or carry out some action relating to the administration of justice.

58
Q

What is dangerousness?

A

It refers to the likelihood of a person (with or without a mental disorder) committing a serious act of violence with little provocation (being provoked) in a variety of real life situations.

59
Q

Who assess dangerousness?

A

Forensic psychologists-

Use assessments and reports about dangerousness- what is the risk of allowing this person into the community (bail, sentencing and prevention detention, conditions of parole, rehabilitation)? It is long term and used in the criminal justice system.

60
Q

What are the risk factors that lead to dangerousness?

A

Demographic factors
History and background
Mental State

61
Q

What are some examples of demographic factors that lead to dangerousness?

Remember at least two.

A

Male
Young age
Poor background
Poor social support (employment difficulties, unstable relationships)

62
Q

What are some examples of history and background factors that lead to dangerousness?

Remember at least two.

A

Previous episodes of violence/convictions: numerous serious offences, young age at their first violent, lack of remorse (guilt, regret, shame)
Alcohol or substance abuse
Has a serious mental illness (ex- schizophrenia)
Poor self control and impulsivity- acting without thinking of consequences
Doesn’t take recommended medication or attend recommended therapy sessions
Drug use by father
History of parental fighting
Abuse in childhood

63
Q

What are some examples of mental state that can lead to dangerousness?

Remember at least two.

A

Preoccupations with, or plans to be violent (has large collection of violent videos) and has access to weapons
Current threats to be violent (when people have restraining orders taken against them)
The presence of paranoid delusions (ex- wrongly believes that is being watched by others)
Psychopathy

64
Q

Is dangerousness linked to mental disorder

A

It is assumed that mental disorders are associated with criminal behaviour and that mentally disordered prey on innocent and that they attack unsuspecting strangers in public areas. Also tends to be reinforced by media. ALL WRONG

4% of Aus offenders were recorded to have a mental disorder in 1999
The location is more likely to be private

A mental disorder is taken into consideration when assessing dangerousness

65
Q

What is a psychopath?

A

A person suffering from chronic mental disorder with abnormal or violent social behaviour. They can be an unstable and aggressive person.

66
Q

How to you assess dangerousness?

A

Using structured clinical judgement: a method of assessing an offender’s risk or future violent behaviour.

Uses a combination of: forensic psychologist professional training (knowledge, skills and expertise), consideration of the individual risk factors and offenders scores on a violence risk assessment (historical- clinical- risk management- 20, psychopathy checklist- revised)

67
Q

What steps are taken to assess dangerousness (steps for structured clinical judgment)?

A

1- gather information from the offender, the offender’s family, the victim’s and their families, police and thier reports, court reports and other health professionals (doctors, psychologists, nurses, social workers, etc.)
2- conduct risk assessment (tests)
3- examine demographic factors, history and background and mental state (three things that influence risk of violence)
4- determine the dangerousness and risk of the offender

68
Q

What is the accuracy of dangerousness predictions?

A

True positive: a correct prediction that the individual will be violent
True negative: correct prediction that the individual will not be violent
False positive: incorrectly identified someone as posing a future risk of violence when in fact they don’t
False negative: incorrectly incentivised someone as posing no future risk of violence when in fact they do

Uses contingency table
Will be violent Is violent Is not violent
Won’t be violent 1 3

69
Q

What is an eye witness?

A

Someone who has first hand knowledge about a specific event or crime through their senses (seeing, hearing, smelling, touching) and can help others understand what happened at an event/crime

70
Q

What is an eyewitness memory?

A

Refers to the eyewitness’s memory of the specific event or crime

71
Q

What is an eyewitness testimony?

A

Refers to the verbal or written statement the person gives about what they remember about the specific even or crime they witness, relying solely on their memory.

Often includes information about the suspect, the details or the crime, who else was there, the sequence of events, time of day, etc.

72
Q

What is the difference between eyewitness testimony and eyewitness memory?

A

Eyewitness memory is what the person remembers, but eyewitness testimony is what the person says or writes about what happened

73
Q

What is memory?

A

An information processing system that obtains, retains and receives information.

Important in eyewitness memory and testimony as someone can be wrongly convicted if you give false data (get it wrong)

74
Q

What are the three stages of memory?

A

1- encoding
2- storage
3- retrieval

75
Q

What happens in the encoding stage for memory?

A

It is a way that information is converted so it can be stored in memory.

When compared to a computer- typing on your computer

76
Q

What happens in the storage stage for memory?

A

Refers to the retention of information so that it can be used at a later time.

Compared to computer- saving the information on your hard drive

77
Q

What happens in the retrieval stage of memory?

A

Refers to the process of locating and recovering of stored information from memory.

Comparing to computer- finding a file on your hard drive

78
Q

What are factors that can influence eyewitness memory?

A
VERY WET TOES MAY CAUSE A CHILL
V W T M C
Problems with encoding:
- Violent distraction
- Weapon focus

Problems with retrieval:

  • Trace-dependant forgetting
  • Motivated forgetting
  • Cue-dependant forgetting
79
Q

How can problems with encoding influence memory?

A

We may only encode some information or distort the information we encode.

Two factors:
Violence distraction
Weapon focus

80
Q

What is violence distraction

A

Refers to an eyewitness’s decreased ability to recall what they witnessed, the more violent the crime, the less accurate the memory.

Have better memory for non-violent event

Yerkes-Dodson Law of Arousal- high levels of arousal lead to lower levels or performance

81
Q

What is weapon focus?

A

Refers to an eyewitness’s decrease ability to give an accurate description of the perpetrator when a weapon is used in a crime.

In violent events, witnesses focus on the weapon and don’t focus on anything else- reduced focus results in reduced encoding.

82
Q

What did Loftus do (psychologist)?

A

Showed two different videos of the same event, but one had a gun and one had a cheque.

The people who saw the video with the gun were unable to accurately identify details of the context and people who saw the video with the cheque who able to accurately identify details of the context.

Because attention is drawn to the weapon.

83
Q

How can problems with retrieval influence memory?

A

Some information is easier to retrieve while some information is harder. It is when we have trouble retrieving information- forgetting.

Three factors:
Trace-dependant forgetting
Motivated forgetting
Cue-dependant forgetting

84
Q

What is trace-dependant forgetting?

A

Assumed that forgetting is a result of the decay of a memory through the passing of time. Memories fade with time, when something new is learned a memory is formed.

Memory trace: a physical or chemical trace, or impression, that is formed in the brain when something new is learned. The memory trace fades in time.

A person’s memory of accidents or crimes fades the longer the delay between witnessing a crime and when asked to retrieve it.

85
Q

What is motivated forgetting?

A

Refers to forgetting that has occurred when information has been unconsciously blocked or hidden from a person’s consciousness because it is too painful or unpleasant to remember.

Sigmund Freud
Repression; a desire to forget, occurs unconsciously, self defence- protect ourselves from harm. The information is not forgotten, it is just stopped from being retrieved.

Thought to be retrieved through hypnosis. Typically of very violent or dangerous crimes.

86
Q

What is the difference between repression and suppression

A

Repression: unconsciously forgetting (r=rape)
Suppression: consciously forgetting

87
Q

What is a retrieval cue?

A

A retrieval cue is any stimulus that assists in the process of locating and recovering information stored in memory

88
Q

What is cue-dependant forgetting?

A

When we can’t retrieve our memory because we can’t find the cues to get them, the memory is stil, there.

Two types of retrieval cues:
State dependant (your mood at the time)
Context dependant (the surroundings of the memory)
89
Q

How can we help eyewitnesses remember what they saw?

A

5 police procedures:
1- the cognitive interview (don’t change their thoughts, asking questions, finding cue)
2- forensic hypnosis
3- line up (visual cue)
4- mug shots
5- constructing a facial composite (drawing)

90
Q

Why is a cognitive interview useful in helping with the accuracy of memory?

A

Because the person who is trying to retrieve the memory isn’t asked questions which could distort or change their memory. This helps them to give an as accurate as possible memory based on what they remember.

91
Q

What is an expert witness?

A

Someone with specialised knowledge, skills or expertise in the information they present before a court

92
Q

When is an expert witness used?

A

When the court requires knowledge that is outside an ordinary person’s expertise

93
Q

Who hires an expert witness?

A

Hired by the defence or prosecution in hope that the expert opinion and evidence provided will support their case. It is possible for all experts to agree with each other.

94
Q

What are the roles of an expert witness?

A

Assessing a defendant’s fitness to enter a plea (guilty or not guilty)
Assessing a defendant’s fitness to stand trial
Assessing an offender’s risk of future violence (dangerousness)
Eyewitness memory
Cases where criminal responsibility needs to be determined

95
Q

Who are qualified to be an expert witness?

A

Medical doctor
Someone skilled in ballistics (ammunition)
Someone skilled in analysis of the test reports from DNA
