Born Bad or Made Bad?
Lecture notes
Recidivism
Reoffending after original offence
Only a small percentage of people commit the largest percentage of crime
Reoffending after non-custodial sentence much higher in juveniles vs adults (~20% vs ~45%)
Reoffending after incarceration is much higher in general ( 40% for adults and around 65% for juveniles)
Victorian Sentencing advisory council - Across 2017-18 percentage of prisoners released who returned to prison within two years lowest in SA and highest in NT, NSW is second with around 50%, national aerage is around 46%
Risk assessment
Involves attempting to identify the probability that an individual will engage in future criminal behaviour
Risk vs dangerousness:
Risk - Predicting likelihood of occurrence
Dangerousness - Predicting likely consequences of offending - how “serious” the crime is
Dangerousness | High | Low |
High | Mass murder | Homicide |
Low | Repeated drug possession | Drug possession |
Psychopathy
A series of socials undesirable affective, interpersonal, and behavioural characteristics
It is NOT a disorder, it is a personality trait
Labelling can be stigmatising
Distinct from anti-social personality disorder
Psychopathy and violent crime
Individuals with psychopathy commit a disproportionately high number of criminal offences
Hare and McPherson (1984):
Individuals with psychopathy had more criminal charges overall, and more criminal charges for violent crimes (e.g., robbery, assault) then individuals without psychopathy
Harris, Rice and Cormier (1991):
Individuals with psychopathy were also more likely to reoffend than those without psychopathy
Assessment of psychopathy
The Psychopathy Checklist Revised (PCL-R) developed by Robert Hare (1984, 1991)
Used worldwide as an assessment tool to identify offenders likely to reoffend violently (as defined by psychopathy)
PCL - R
20 item scale separated in to two dimensions (Emotional/interpersonal and Social Deviance)
Assessors will go over the case information of the individual (life history crime history etc) and then will engage in a semi-structured interview with the individual
After interview assessor will rate individual on the factors scoring 0, 1, or 2 for each (range 0 to 40)
Score of 30+ indicates psychopathy
Average non-psychopath scores about a 6 or 7
First factor is related to primary psychopathy and second to secondary psychopathy
Development of psychopathy
Reserved to adult populations but certain personality traits and diagnoses in childhood can increase likelihood of possessing high levels of psychopathy
Callous-Unemotional traits
Oppositional Defiant Disorder (ODD)
Conduct Disorder
Summary
Recidivism rates are high, suggesting a national problem
Psychopathy is an aspect of personality consisting of undesirable affective, interpersonal, and behavioural characteristics
Individuals with psychopathy may be at heightened risk of criminal offending
Psychopathy is not to be confused with antisocial personality disorder, or other diagnoses with antisociality
When is your child a psychopath - reading notes
Researchers believe that nearly 1% of children exhibit callous and unemotional traits, about as many as have autism or bipolar disorder
More than 50 studies have found that kids with callous and unemotional traits are more likely to become criminals or display aggressive, psychopathic traits later in life
While adult psychopaths only make up a small amount of the population studies suggest that they commit half of all violent crimes
Researchers at King’s College London tested more than 200 five-week-old babies tracking whether they preferred looking at a person’s face or at a red ball, those who favoured the ball displayed more callous traits two and a half years later
Psychopathic brains have neural abnormalities
The limbic system, the set of brain structures involved in processing emotions, contains less grey matter - a psychopath may understand intellectually that what they’re doing is wrong but they don’t feel it
Experts point specifically to the amygdala, someone with an undersize or under active amygdala may not be able to feel empathy or refrain from violence
They also have an overactive reward system especially primed for drugs, sex, or anything else that delivers a ping of excitement.
The best physiological indicator of which young people will become criminals as adults is a low resting heart rate - Adrian Raine, University of Pennsylvania
