What research supports the top-down Approach? (The Top-Down Approach)
- Canter analysed 100 US murders using ‘smallest space analysis’
- assessed co-occurence of 39 behavioural aspects
- Subset of features of serial killings which align with typology for organised offenders
What suggested there may be wider application to the top-down approach? (The Top-Down Approach)
- Meketa reported it applies to burglary leading to an 85% rise in solved cases in 3 US states
Who suggested that behaviour of rapists gives insight to their opinions of gender generally? (The Bottom-Up Approach)
- Dwyer suggested some want to humiliate their victims whereas some are more apologetic
Who came up with the circle theory? (The Bottom-Up Approach)
- Canter
- Patterns of offending form a circle around the offenders home base
How did Canter come up with his Circle theory? (The Bottom-Up Approach)
- John Duffy ‘railway rapist’ 24 sexual attacks and 3 murders
- Canter analysed geographical info and correctly assumed where he lives, marital status, height and acne
What further research evidences the bottom-up approach? (The Bottom-Up Approach)
- Canter and Heritage
- 66 sexual assault cases using smallest space analysis
- Each displayed characteristic patterns of behaviour
- Supports basic principles of investigative psychology
What research further supported geographical profiling?
- Lundrigan and Canter using smallest space analysis
- 120 murder cases involving serial killers
- Found spacial consistency in behaviour and they all created a centre of gravity
Who came up with the atavistic form? (A Historical Approach)
- Lombroso wrote his book ‘the criminal man’ in 1876 referring to criminals as ‘genetic throwbacks’
Who researched the atavistic form? (A Historical Approach)
- Lombroso examined skulls of 383 dead convicts 3839 living ones and concluded 40% have atavistic characteristics
Who suggested Lombroso’s legacy was negative? (A Historical Approach)
- DeLisi suggested Lombroso was a racist
Who contradicted Lombroso’s research? (A Historical Approach)
- Goring compared 3000 offenders and 3000 non-offenders and found no differences between cranial characteristic
Who conducted twin studies for the genetic explanation? (Genetic Explanation)
- Christianson studied over 3500 pairs of twins in Denmark and found concordance rates for offending behaviour of 35% for identical twins and 13% for non-identical twins
Who conducted adoption studies for the genetic explanation? (Genetic Explanation)
- Crowe found adopted children whose mam had a criminal records had a 50% risk of having a criminal record by the age of 18
- otherwise they had a 5% risk
Who investigated candidate genders for the genetic explanation? (Genetic Explanation)
- Tiihonen did a genetic analysis of 800 Finnish offenders and found some genes more be associated with violent crime
- MAOA associated with serotonin and aggression
- CDH13 linked with ADHD and substance abuse
- 5-10% of severe violent crime in Finland is attributed to these genes
Who supported the stress-diathesis model? (Genetic Explanation)
- Mednick: 13,000 Danish adoptees
- Neither bio or adoptive parents had convictions it was 13.5%
- Rose to 20% when bio parents has convictions
- rose to 24.5% when both had convictions
Who research the pre-frontal cortex in the neural explanation? (Neural Explanation)
- Raine conducted studies into APD brain and found reduced activity in pre-frontal cortex which regulates emotional behaviour
- Raine found an 11% reduction in volume of grey matter in those with APD
Who researched mirror neurons? (Neural Explanation)
- Keysers found only when asked to empathise did those with APD’s mirror neurons (controls empathetic reactions) activate
Who researched the link between criminality and the pre-frontal cortex? (Neural Explanation)
- Kandel and Freed reviewed evidence of frontal lobe damage and antisocial behaviour
- those with damage show impulsive behaviour and emotional instability and an inability to learn from mistakes
Who suggested the cause of APD was not biological? (Neural Explanation)
- Farrington suggested a group of men who scored high on a psychopathy test experiences factors during childhood e.g physical neglect
Who came up with the theory of the criminal personality? (***** theory)
- Eysenck
What evidence supports the criminal personality? (Eysenck’s theory)
- Eysenck and Eysenck compared 2070 offender with 2422 controls on the EYP
- Offenders scored highly on extraversion, neuroticism and psychoticism
Who contradicted two integral elements of the criminal personality? (Eysenck’s theory)
- Farrington did a meta analysis and suggested offender score high on psychoticism but not extraversion of neuroticism
Who suggest that Eysenck’s theory was too simplistic? (Eysenck’s theory)
- Moffitt drew a distinction between offending in adolescence and in adulthood (‘career offender’)
- personality traits alone are a poor predictor of how long offending behaviour will go on
Who came up with moral development? (Levels of moral reasoning)
- Kohlberg proposed peoples judgements on moral questions can be summarised in a stage theory
- low levels of moral reasoning associated with offending behaviour
- A group of violent youths were at significantly lower level of moral development than non-violent youths.
