What did Gray et al. (2019) find in terms of impulsivity and psychopathy?
Found the results support the idea of primary and secondary psychopathy.
Secondary psychopathy scored higher on impulsivity, vice versa for primary psychopathy
What are some limitations of the PCL-R?
Interviews are open to manipulation.
Antisocial should not be part of the diagnosis - may just be a conseqeunce of the personality features rather than core for diagnosis.
PCL-R holds a lot of consequences - e.g., death penalty
It’s hard to administer - need specialist training
Name some alternatives to the PCL-R.
SPR4 - based on the PCL-R four facet model.
PPI-R - based on factor analysis.
TriPM

Fearless dominance and self-centred impulsivity.
Maybe cold heartedness.
What is the TriPM based on?
Theory of end-phenotypes - boldness, meanness and disinhibition
What did Hart et al. (1988) find when looking at the psychopathy and violence?
80% of those with high psychopathy returned to prison during examination period.
True for 60% medium psychopathy and 20% low psychopathy.
What did Hare et al. (2000) find when looking at psychopathy and reconviction rates?
High psychopathy - a lot more reconnections both general and violent crimes. A lot more violent crimes though than low psychopathy
What did Woodworth and Porter (2002) find when classifying homicides and psychopathy?
Nearly all homicides committed by psychopaths were cold-blooded.
Homicides for psychopaths was pretty evenly reactive and proactive.

Yes - psychopathy measures just as predictive of future crimes and violence for women as for men
What did Viding et al. (2005) find in terms of genetics and psychopathy?
(UK) Genes account for 70% of the individual differences in CU traits.
Genetic contribution was highest when CU traits were combined with antisocial behaviour (Factor 1)
What did Wootton et al. (1997) find in terms of the enviornment and the development of psychopathy?
The worse the parenting, the more conduct problems.
Except for those with CU traits - they had higher conduct problems and parenting had no effect on this.
Is it true that psychopaths cannot be treated?
Unknown but programs now aren’t designed with psychopaths in mind so this might explain the difficulty in treating at the moment.
