Hazelwood and Douglas (1980) – ‘The Lust Murderer’
Hazelwood and Douglas (1980) – ‘The Lust Murderer’, FBI Law Enforcement Bulletin 49 (4), 18-22.
Background
This is the first study we look at from the ‘Making a Profile’ section of ‘Making a case’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘Top Down.’
This study is also referred to as:
- Hazelwood et al., (1980)
- Douglas et al., (1980)
Firstly, what is profiling? Profiling is a range of characteristics proposed by a psychologist of an offenders to the police in order to narrow the scope of their investigation.
The background study for this theory, is Holmes and Holmes (1989).
Firstly, what is profiling? Offender or criminal profiling is simply the attempt to predict and create the likely traits and behaviours of an offender of a crime. The likelihood is that you already could begin to have a guess at the type of person that committed a crime. For example three women are found strangled and sexually assaulted at three different, but closely located train stations. It is more than likely that a male committed these offences. Criminal profiling done by professionals is in essence what we just did, but it goes into more depth.
Holmes and Holmes (1989) identified 3 aims of profiling:

Guðjónsson and Mackeith (1990) – ‘A Proven Case of False Confession: Psychological Aspects of the Coerced-compliant type’, Medicine Science and the Law 30, 329-35
Background
This is the third study we look at from the ‘Interviewing Suspects’ section of ‘Making a case’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘False Confession’
Guðjónsson and Mackeith (1990) is a case study about a 17 year old boy who confessed to a crime and was subsequently imprisoned for one year. Later it was found out that his confession was false and he was not guilty of committing the crime. Guðjónsson and Mackeith wondered how such false confessions can arise.
Guðjónsson (1992) suggests there are three types of false confessions:
Voluntary – This is when a person freely confesses to a crime.

Fisher et al., (1989) – The Cognitive Interview
Fisher et al., (1986) – ‘Field test of the cognitive interview: enhancing the recollection of the actual vicitims and witnesses of crime’, Journal of Applied Psychology 74 (5), 722-7.
This study is also referred to as:
- Fisher et al., (1989)
- Fisher and Geiselman (1989)
- Geiselman et al., (1989)
Background
This is the third study we look at from the ‘Interviewing Witnesses’ section of ‘Making a case’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘The Cognitive Interview.’
Fisher et al., (1989) focuses on police interviews of witnesses.
What is an interview?
An interview is simply trying to elicit information from a person or witness, while keeping the information valid. This is easier said than done. You may remember two studies from AS: Loftus et al., (1974) and Samuel and Bryant (1984), which demonstrate this. Firstly, Loftus showed the impact that leading questions could have upon participant recall and she concluded that an actual change in memory had occurred. Memory is easily malleable, changing how a question is asked can change the memory itself. Secondly, Samuel and Bryant showed the impact of repeating the same question. Repeating the same question to children will cause them to completely change their answer, even if their answers were perfectly correct.

Mann et al., (2004) – ‘Detecting True Lies: Police Officers’ Ability to Detect Suspects’ Lies’
Background
This is the second study we look at from the ‘Interviewing Suspects’ section of ‘Making a case’. As part of your OCR A2 Psychology Exam. It is further categorised into ‘Detecting Lies.’
Can you tell when someone is lying?
If you answered yes, what cues to do you use to detect lies? Eye movements? Gestures?
Could you detect lies at a rate better that chance (50%)? This would mean that you would have to be able to accurately ascertain the truthfulness of at least 6 out 10 statements.
