Q

Lykken theorizes about psychopathy and sociopathy:

A
  • psychopaths born with differences that lead them to risk-seeking and an inability to internalize social norms
  • sociopaths have relatively normal temperaments. their disorder is more of an effect of negative sociological factors

Q

somatic marker hypothesis

A

Damasio

  • gut feelings are crucial for efficient decision making
  • concept that not only the mind thinks, the body also plays a role in how we think
  • somatic markers are created during the process of education and socialization through the connection between certain types of stimuli and certain types of affective states

Q

uncinate fasciculus

A

white matter tracts between limbic and medial frontal cortex (including amygdala to vmPFC)

22
Q

violence inhibition mechanism: blair, 1995

A

cognitive mechanism which, when activated by non-verbal communications of distress, initiates a withdrawal response; a schema will be activated predisposing the individual to withdraw from the attack

23
Q

summary of brain data on moral decision making

A

-vmPFC increased activity during moral vs nonmoral in non-psychopaths but not psychopaths
- atypical pattern of brain activation and connectivity from anterior insula and amygdala to OFC and vmPFC in “imagine other empathy” but not “imagine self”

24
Q

Actus reus

A

guilty act

25
Q

mens rea

A

guilty mind

26
Q

moral penal code standard

A

a defendant is not responsible for criminal conduct if “at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the criminality of his conduct or to conform his conduct to the requirements of the law”

27
Q

Frye admissibility of scientific evidence

A

expert opinion based on scientific technique is generally accepted as reliable in the relevant scientific community

28
Q

Daubert admissibility of scientific evidence

A

“validity” of scientific testimony based on: empirical testing, peer review/publication, known/potential error rate, the existence and maintenance of standards and controls, the degree to which the theory and technique is generally accepted by a relevant scientific community

29
Q

amygdala

A

fear, threat, arousal, aggression

30
Q

summary of the social decision-making studies

A
  • primary (but not secondary) psychopaths resemble vmPFC lesion patients in their decision making
  • this shows that vmPFC may play a critical role in certain types of psychopathy
31
Q

summary of prison MRI studies

A
  • psychopathic criminals have measurable abnormalities in the vmPFC-amygdala circuit
  • deficient connectivity may relate to deficits in emotion, empathy, social/moral decision-making, reinforcement learning
32
Q

affective perspective taking

A
  • affective empathy and cognitive empathy
  • psychopathy is related to deficits in affective empathy
  • results: psychopathy was negatively re;ated to accuracy when identifying fear, happiness, and sadness
33
Q

psychopathy is negatively related to fear perspective-taking in:

A
  • left anterior insula, precuneus
  • prediction signals in anterior insula may be impaired in psychopathy
34
Q

meta-anayltic results show psychopathy is related to

A
  • increased volume of striatum
  • increased activity in amygdala across a variety of tasks
  • increased activity in default mode network across a variety in anterior cingulate across a variety of tasks
35
Q

The low fear hypothesis

A

Lykken, 1995

1) people with primary psychopathy are born with below average levels of fearfulness ( a low fear IQ)

2) the fearfulness of psychopathic individuals makes them difficult to socialize (explaining psychopathic traits)

low fear>weak attachment

  • children typically seek reassurance from parents to reduce fear. this makes children dependent on their parents and increases “social monitoring” to maintain parents’ approval
  • low fear weakens this attachment by reducing motivation to seek approval and attachment

critique = is it a fear deficit or more general problem

36
Q

passive avoidance learning

A

learning to avoid aversive stimuli
- not engaging in a behavior to avoid negative consequences

37
Q

Newman’s response modulation hypothesis

A
  • psychopaths are characterized by a response modulation deficit that interferes with their ability to use secondary (or non dominant information) to regulate goal directed behavior
  • over-selective attention process
38
Q

how do we test Newman’s response modulation hypothesis?

A

passive avoidance tasks

39
Q

General Newman’s hypothesis

A
  • the principal behavioral, cognitive, affective, and neural correlates of psychopathy will be moderated by their focus of attention
  • deficit on tasks due to focus on reward and failure to attend to losses. this over-selective attention results in a failure to self regulate
40
Q

psychopaths have deficits in:

A
  • passive avoidance learning
  • conflict monitoring (stroop and flanker tasks)
  • fear potentiated startle/emotion modulated startle
  • amygdala activation
  • electrodomal reactivity
  • empathy related brain activation
  • facial affect recognition

these findings are all moderated by their focus of attention

all of the deficits appear and disappear depending upon whether the critical stimuli are intrinsic, or peripheral to, psychopath’s primary focus of attention

41
Q

Impaired integration model of psychopathy

A
  • psychopathic individuals have difficulty rapidly integrating multicomponent perceptual info (attention bottleneck), which in turn influences the quality of mental representations and shapes the development of associative neural networks in the brain
  • language component as well
42
Q

distal-proximal causes

A

1) low fear hypothesis: amygdala dysfunction - poor fear conditioning - poor passive avoidance

2) somatic marker hypothesis: vmPFC dysfunction - weak somatic markers - poor violence inhibition

3) impaired integration hypothesis: reduced connectivity - impaired integration - shallow affect, week inhibitory associations

43
Q

PCL-R: an accidental risk tool

A
  • designed to assess personality construct
  • happens to predict general and violent recidivism
    -NOT a comprehensive risk tool
44
Q

psychopathy as risk factor for violent and general recidivism

A
  • 2-5x more likely to recidivate than non-psychopathic offenders
  • meta-analytic studies have consistently indicated that factor 2 is a stronger predictor of recidivism than factor 1 (whereas factor 1 is more instrumental violence)
45
Q

Violence risk assessment guide (V-RAG)

A

12 items scored related to violent recidivism

(improved predictive ability if incorporated other risk items) - better than the PCL-R alone

46
Q

summary: violence & psychopathy

A
  • higher risk of violence
  • violence is more predatory than affective
  • commit more crimes
  • more likely to use weapons
  • more aggressive in prison
  • more likely to escape
  • more likely to have staff relations
  • correlates with sadism, but its not the same thing
  • serial murders are psychopathic but most high in psychopathy are NOT murders
47
Q

Wong & Hare psychopathy treatment program

A
  • goal is to reduce the frequency and severity of violence
  • appeal to their self - interest to use strengths in non-criminal manner
  • behavioral self-management vs cure
  • CBT
48
Q

cognitive remediation

A
  • “brain training”
  • increasing focus on context to address over-selection attention
  • can lab tasks on computer, video games, meditation, train the brain?
  • learning to focus on peripheral cues; recognize emotions; pick up on subtle cues; proactive pro-social behaviors in games/tasks
49
Q

key neuropsychological factors & relationship to self-regulation

A
  • vmPFC lesions result in ‘pseudopsychopathy’
  • vmPFC associated with impaired emotional processing/regulation
  • social/emotional & economic decision making in primary psychopathy & vmPFC patients similar
  • Damasio’s somatic marker hypothesis (related with vmPFC related feedback)
50
Q

summary of key points with comparison of vmPFC and primary psychopathy

A
  • ultimatium game: more likely to make unfair
  • dictator game: lack of empathy
  • primary psychopaths similar to vmPFC lesion patients
51
Q

vmPFC-amygdala connectivity

A
  • vmPFC and amygdala are densely interconnected
  • amygdala involved in fear and anxiety
  • vmPFC involved in emotion regulation and socio-moral decision-making
  • psychopaths have deficits in fear, affect, aggression, and decision-making
