Module 10 Flashcards
What is Psychopathy?
A personality disorder characterized by an arrogant, deceitful interpersonal style (how they interact with other people)
deficient affective experiences ( how they experience emotion: general lack of empathy, emotional reactivity is low)
impulsive and irresponsible behaviors (do not care about their actions and what the consequences will be)
early onset & diverse antisocial behaviors (they engage in antisocial behavior, a long history of a lot of different types and a lot of them
Long criminal history)
How do you assess psychopathy?
Self-report inventories: most common
Informant rating: Only for children, when you ask someone else to report on the emotions
Clinical rating: clinical professional, interview and time intensive
What is the most common assessment?
Psychopathy checklist-revised 9PCL-R)
It is a semi-strutted interview + file review with a 20 item questionnaire on a 3 point scale. there is a total score of 40, it is a dimension rating where you look for spikes, >30 is more definite
There is a youth version (PCL:YV)
only qualified professional people can administer it

What will a psychopathic suspect behave like in an interview?
Try to outsmart interviewer
enjoy being focus of attention
attempt to control
will not be fooled by bluffs
attempts to shock
What are recommendations for interviews with psychopaths?
Be very familiar with the case - have to be able to challenge the lies
convey experience and confidence
admiration - they have huge egos
avoid criticism - they will take that badly
avoid emotions about the case - they don’t have them
What are the overlaps with antisocial personality disorder (ASPD) and psychopathy?
In the prison population, 60-80% have ASPD, 10-25% of that have psychopathy. Just because you have ASPD, doesn’t mean you have psychopathy. people with psychopathy will most likely meet the standards for ASPD
What have twin studies shown in psychopathy?
Viding et al. showed that high callous-unemotional traits and antisocial traits are heritable.
Waldman et al. showed that there is about the same amount of genes involved as any other personality traits (introverted, etc.) Meaning it is about 50%
What are the 3 structural anomalies for people with psychopathy?
The Prefrontal cortex:
They have reduced function + reduced connectivity to amygdala. They don’t experience emotions and those centers don’t really communicate well with the prefrontal cortex, which makes them not really get punishments. This makes them impulsive. Overall there is volume reductions. This is an important area for decision-making and impulse control
Amygdala/hippocampus:
Part of the emotion/memory center. there is less blood flow/less processing of emotional stimuli. Lower connectivity, structurally and functionally it doesn’t work great. The most consistent one is fear, they do not experience fear.
Striatum:
Involved in voluntary movement, decision-making and processing rewards. Increased volume in psychopaths, which makes them reward-oriented; less affected by consequences. It’s bigger, lights up more. They are more reward sensitive then others, if they have a goal they will go for it because it; single minded on the goal
What is the cognitive deficit hypothesis called?
Response modulation hypothesis:
People with psychopathic traits, they are more likely to go with the perseveration route rather than response modulation, where they change their behavior based on an event. They are unable to account for new stimuli in order to change to a new route. When they make a decision, they cannot see past their goal.
What is the affective deficit hypothesis?
Fearlessness hypothesis: The emotion they lack the most is fear.
They tested this in Patrick et al. using the startle reflex; reflex occurs when something unexpected occurs, it is magnified if person is in negative emotional state and reduced in a positive emotional state. it is mediated by circuits in the amygdale. Patrick et al. was one of the first well designed studies around fear in psychopaths. It measured the startle reflex through blinking, which shows fear. It used incarcerated offenders (psychopaths vs. non psychopaths) and showed three different pictures (pleasant, unpleasant, and neutral). Then they measured the blinks.
It showed that normal people blink more when they are upset.
Psychopaths don’t show the increase startle response to negative images, there is no change
What are broad conclusions on psychopathy and emotional processing?
Emotions play little role in their thinking, language, and behaviors
their approach to the world is predatory
they put on a good show
They learn to mimic emotions by seeing how other people react to things; part of how they manipulate people, just like someone who is colorblind does
They learn the notes but not the music of emotions
What are childhood antecedents for psychopathy (Farrington & Bergstrom)?
All significant factors:
Criminal Father/Mother
Depression Mother
Uninvolved father
Poor supervision
disrupted family
hyper activity
high dishonesty
high impulsivity
What is the interaction model?
Individual is born with a certain predisposition (determined by genetics) and through interactions with environmental factors psychopathic traits may develop.
This is how you describe most people, without the genes and without the bad environment are both possible, this is the average
Factor 1 (callous-unemotional traits) more influenced by genetics; Factor 2 more influenced by the environment
How does the criminal justice system use a psychopathic diagnosis?
They justify:
Imposing adult sentence on a child
guilt determination
denial of parole
termination of parental rights
death penalty
longer sentences
DO/LTO hearings
criminal responsibility
increased supervision after release
pretrial secure detention
