Forensic psychology
Forensic psychologists apply psychological knowledge, theory and skills to the understanding and functioning of legal and criminal justice systems
5 principles of the Classical School of Thought
Rationalism Hedonism Punishment Human Rights Due Process
Rationalism
Human beings are fundamentally rational, and most human behaviour is the result of free will coupled with rational choice
Hedonism
Pain and pleasure are the two central determinants of human behaviour
Punishment
A necessary evil, is sometimes required to stop law violators and to serve as an example to others who would also violate the law
Human Rights
Root principles of right and wrong are inherent in the nature of things, and cannot be denied
Due Process
People accused of a crime are considered innocent until proven guilty, and they have the chance to go to trial and face the judicial system
What is the basic underlying principle of the Peelian principles of policing? Describe briefly what impact the Peelian principles had on modern police forces
The key principle is that the power of the police comes from common consent as opposed to the power of the state. The police force has changed from being known as ‘forces’ and now serve as more a service industry to the public
What is police bias and how might it develop? Outline one way in which we might overcome police bias in the community
Officers are at risk of developing negative stereotypes of groups of people with whom they interact with during police work. For example, African Americans are approximately four times more likely than white people to be killed in encounters with the police in the united states. More foot patrols by officers who stay in the same neighbourhood is a way to overcome police bias.
What are some of the main features of the FBI-style of criminal profiling which bring into question its validity?
A willingness to encompass experience and intuition as a component of profiling
A relatively weak empirical database
A concentration on the more serious, bizarre, and extreme crimes
Extensive contact with the investigating team of police officers at all levels
Behavioural Evidence Analysis (BEA)
A form of criminal profiling, BEA is primarily a deductive approach and consists of the testing of physical evidence
Stages of BEA
Equivocal forensic analysis - analysing physical evidence
Victimology - examines all aspects of the victim
Crime scene characteristics - profiler determines factors of crime scene
Offender characteristics (criminal profile)
Describe four key differences between organised and disorganised serial killers
Organised: Psychopathic Plan crime ahead Charming, intelligent Cleans up crime scene
Disorganised: Psychotic Does not plan crime Socially incompetent Doesn't clean up crime scene
Voluntary
Personally motivated in the absence of external pressures
eg. Desire to cleanse guilty feelings
Coerced - compliant
Occurs in response to instances where the suspect reacts to the demands and pressures
Coerced - internalised
Occurs when suspects believe that they have actually committed the crime
eg. This can be due to amnesia, drugs or alcohol
What are the six major tactics which police use when interrogating suspects of serious crimes?
Appeals Intimidation Manipulation Leading questions Robust challenge (direct challenges that the suspect is lying) Soft challenge (soft, friendlier tone)
What is the cognitive load theory of lying and how can we use this to catch liars?
It is cognitively more demanding to invent a lie than to merely report the truth. We can determine lying with slower response times and a decrease in movements
The Hare Psychopathy Checklist lists 20 personality traits which are characteristic of psychopaths. These traits are grouped under four factors. List each of the four factors and give an example of a trait which falls under each
Interpersonal characteristics - Grandiose view of self-worth
Affective characteristics - Lack of empathy
Lifestyle characteristics - Irresponsibility
Antisocial characteristics - Delinquency as a juvenile
What are the three types of Hedonistic killers. List and briefly describe each of these
Lust - The primary motive is exclusively sex, even if the victim is already dead.
Thrill - Primarily motivated to induce pain or a terrified reaction from the victim.
Comfort (Gain) - The motive is to acquire activities or objects that provide a comfortable and luxurious lifestyle.
three key issues that affect the investigation of the link between mental illness and crime.
- Definitions of mental illness - Mental illnesses are largely defined in terms of a number of diagnostic categories. If one of these diagnostic features is violence, then there will be an association between mental disorder and violent crime.
- The confounding effects of medication - Psychiatric drugs are often prescribed to the mentally ill to control the symptoms of their illness. These drugs may have side effects leading to violent behaviour
- Misclassification of the mentally ill and violent - The use of hospital and crime records to classify people as mentally ill and violent may depend on a flawed classification system. For example, the general public may be more likely to report violence or threats of violence by people who show signs of mental illness.
Name two factors which can affect the accuracy of eyewitness testimony. Describe how these factors affect accuracy (in your answer, identify whether the factor is affecting encoding, storage or retrieval).
Post-event information can affect the process of storage (known as the misinformation effect) -
When someone presents misleading information, it can affect your memory of the event
Arousal levels can affect the encoding of information -
When tired, we are less able to code information
When excessively stressed, we are less able to code information
List and briefly describe the five steps in the Cognitive Interview.
- Introduction: Building rapport with interviewee
- Open-ended narration: Recreation of the context of the crime - Ask witness to recall event
- Probing: Obtain open-ended narrative account of witnessed events
- Review evidence
- Closing the interview
Identify the main expert witness arguments used by the defence, and the main arguments used by the prosecution, in the case of Jeffrey Dahmer. What was the verdict?
Defence: argued he suffered from necrophilia and was psychotic
Prosecution: Dahmer’s capacity to exert methodical control was an indicator of his sanity and premeditation.
