Forensic Psychology Flashcards
Walker et al. (2006)
Only 42% of crimes reported in the British Crime Survey (BCS) were reported to the police.
Farrell and Pease (2007)
The number of crimes people can report to the BCS is limited to 5 per year.
Hales et al. (2007)
The offenders who answered the Offending, Crime and Justice Survey (OCJS) were apparently accurate in their answers.
Douglas et al. (2006)
Came up with the six main stages of the top-down approach to offender profiling.
Copson (1995)
82% of police officers said that the top-down method was operationally useful and 90% said they would use it again.
+
75% said that the bottom-up approach was useful but only 3% said it had helped identify the criminal.
Scherer and Jarvis (2014)
Top-down approach offers investigators different perspectives and prevents wrongful conviction.
Snook et al. (2008)
Top-down approach is flawed: ambiguous descriptions can fit any crime and offender, just like horoscopes (Barnum effect).
Jackson and Bekerian (1997)
Intelligent offenders will study psychological profiling and will use this knowledge to deliberately mislead authorities.
Alison et al. (2003)
1/2 of the police officers were given inaccurate profiles but more than 1/2 thought they had accurate profiles. Therefore police officers do not necessarily notice when they have poor profiles.
Turvey (1999)
There is a false separation between organised and disorganised offenders. Behaviour is in fact on a continuum.
Douglas et al. (1992)
A third category, “mixed offender”, should be added to the top-down approach.
Canter et al. (2004)
There is no clear distinction between organised and disorganised offender behaviour. Very few criminals are disorganised.
Davies et al. (1997)
Rapists who concealed fingerprints often had prior burglary convictions.
Salfati and Canter (1999)
Hundreds of cases are compared to check for any similarities or connections, making it easier to catch a perpetrator
+
‘Instrumental opportunistic’, ‘instrumental cognitive’ and ‘expressive impulsive’ themes were found.
Canter and Larkin (1993)
Most criminals have an awareness of the geography of their crimes. 91% were ‘marauders’ and only some were ‘commuters’ (some were neither).
Rossmo (1999)
Came up with Criminal geographic targeting (CGT). It does not specifically solve crimes but us useful for prioritising house-to-house searches.
Petherick (2006)
If the person’s home is not the centre of the crimes, police will have difficulty finding the perpetrator. Also, circles are overly simplistic.
Turvey (2011)
Vancouver PD (where Rossmo was based) stopped using geographical profiling and fired Rossmo because it wasn’t helpful.
Lombrosso (1876)
Atavistic traits indicate criminal personality and behaviour.
Lombrosso (1897)
There are ‘born criminals’, ‘insane criminals’, and ‘criminaloids’ (predisposed to criminality and triggered by the environment).
Kretschmer (1921)
There are somatotypes of criminals, based on body shape.
Carrabine et al. (2014)
Although incorrect, Lombrosso was the first to bring science to criminology and hold a more deterministic view of crime.
+
Restorative justice programmes are now the focus of criminology because of the failures of traditional incarceration.
Goring (1913)
There are no real differences between the physical characteristics of convicts and non-convicts. Convicts were just slightly smaller.
Lombrosso and Ferrero (1893)
Women are less evolved than men. When they have masculine characteristics they become criminals.
