Forensic psychology Flashcards
What are the 2 approaches to criminal profiling?
Top down - American method
Bottom up - British method
How is the top down approach to criminal profiling completed?
Police build an overall picture for all criminals. Each criminal is then placed into this pre existing template and a profile is found.
How is the bottom up approach to criminal profiling completed?
Finding small details then using them to build up a bigger picture.
What information is used in the top down to criminal profiling?
Information regarding the crime
The crime scene
Anything about the offender
What is a offender firstly separated into?
Being organised or disorganised
What are the characteristics of a organised offender?
Lead an orderly life and kill after experiencing a critical event.
Actions at a crime scene reflect control and planning.
Few clues on the crime will be left at the scene.
More likely to lead a verbal approach with victims
Above average intelligence therefore more likely to be employed and may have a family.
What are the characteristics of a disorganised offender?
Commits crimes in the heat of the moment.
Crimes display no preplanning which is shown by the use of items already being at the scene.
Could leave multiple clues at the scene such as blood, fingerprints, semen, or even a murder weapon.
Likely to have lower IQ, being impulsive and socially incompetent possible history of failed relationships.
Tend to be unskilled workers or unemployed.
What are the 4 stages to the construction of an FBI profile?
Data assimilation
Crime scene classification
Crime reconstruction
Profile generation
What happens in the data assimilation stage of constructing an FBI profile?
Profilers reviews the evidence eg crime scene photos, pathology reports etc.
What happens in the crime scene classification stage of constructing an FBI profile?
Decide if the criminal is organised or disorganised.
What happens in the crime reconstruction stage of constructing an FBI profile?
Hypotheses in term of how the murder was committed in term of the sequence of events, victim/offender actions.
What happens in the profile generation stage of constructing an FBI profile?
Create a hypothesis related to all aspects of the likely offender and their life eg demographic background, physical characteristics, behaviours, personality type.
What is the point in constructing a FBI profile?
To apply it to a list of suspects which helps to narrow down the search to make it more time effective.
What is the definition of a serial killer?
Someone who has killed more than 3 people
What did Douglas say are the reasons for there being more than one type of crime scene?
More than one offender
Escalation of situation
Victim forcing a change in approach from the offender
What is a support for the top down approach?
It’s widely used and has been found to be effective.
What did Alison et al (2002) say about the top down approach?
Suggest that the personality theory element of the theories are outdated and not
inline with modern theories of personality, being seen to be driven by stable internal personality traits
that are hard wired, where modern theories recognise the role of environmental factors and personal
development.
What did Keppel and Walter (1999) argue about the top down approach?
That we need to focus upon the motivation of the killers to understand who they are and to apprehend them.
What happens in the British model or Bottom up profiling?
The data derives the formation of the profile, rather than having set profiles which are assigned. Which forces a more deeper and rigours investigation by the police in order to collect every piece of data available to the which can then be used to build the picture.
What is meant by investigative psychology?
The attempt to use psychological theory and statistics to create a suitable profile for the offender based upon there actions.
What did Dwyer (2001) come up with
Interpersonal coherence.
What is meant by interpersonal coherence?
That an offenders behaviour when interacting with victims and how the crime scene is left could be reflected in everyday life.
What can be interpreted by the dump sites and the level of forensic awareness an offender has?
The level of thought and specialist knowledge an offender has, which may show they have been operating for a longer/shorter time.
What are the 2 sorts of serial killer/rapist suggested in Canters circle theory?
Marauders
Commuter
