4
What is morality?
  • Two main viewpoints
  • There is a unitary system for morality (Piaget,
    Kohlberg, Moll).
  • the sets of customs and values that are embraced
    by a cultural group to guide social conduct (p.
    799 Moll, Zahn, de Oliveira-Souza, Krueger,
    Grafman, 2005).
  • Piaget- Theory of Mind and intention
  • 3 mountain problem

  • Piaget- Theory of Mind and intention
  • Kohlbergs stages of moral development
  • Obedience and Punishment
  • Individualism and Exchange
  • Good Interpersonal Relationships
  • Law and Order

  • Universal Principles

7
What is morality?
  • There are multiple systems engaged in a variety
    of forms of processing that fall within our
    cultural concept of morality (Turiel, Smetana,
    Nucci, Haidt, Blair).

16
Emotional Underpinnings
  • Care-based
  • Fear/distress of others
  • Social Convention
  • anger
  • Disgust
  • Disgust of others, taste/smell aversion

17
Cognitive Underpinnings
  • Emotional responses can explain badness, but
    not wrongness (Nichols, 2002)
  • Theory of Mind
  • Piaget
  • Intention
  • Children vs. adults
  • Young et al. (2010)

Trans-cranial Magnetic stimulation

Young et al., 2010
  • By disrupting the Temporal-Parietal Junction,
    intention information processing was disrupted
    resulting in disrupted moral decision-making

21
Emotional Control
  • Emotional control and cognitive development do
    not progress in tandem (Dahl, 2004)
  • Adolescents in particular have trouble with
    emotional control, despite good cognitive
    understanding of rules and consequences (Dahl,
    2004)
  • Moral behaviors are a result of interactions
    between emotional processes, cognitive processes
    and emotional control

22
Engaging in Moral Behavior
  • Emotional data is fed to the orbital-frontal
    cortex (OFC)

23
OFC
24
Engaging in Moral Behavior
  • Emotional data is fed to the orbital-frontal
    cortex (OFC)
  • In the OFC, memory information, emotional input
    and sensory data are combined to form, execute,
    monitor and alter responses.
  • Information about intention and emotion are
    combined in the OFC and emotional control is
    asserted in the prefrontal cortex
  • The prefrontal cortex is not fully mature until
    early to mid 20s

25
Questions to be addressed
  • What is morality from a cognitive neuroscience
    standpoint?
  • What are the underpinnings of moral
    decision-making?
  • Case Examples
  • Whats important for judges relating to the
    development of morality?

26
Case Examples
  • Care-based morality relies on the amygdala
  • OFC is necessary to integrate emotional
    information into decision-making
  • Pseudo-psychopathy
  • OFC damage
  • Psychopathy

27
Pseudo-psychopathy
28
Psychopathy
  • Psychopathy is associated with (Frick White,
    2008 White Frick, 2010)
  • Antisocial behavior
  • Instrumental Aggression
  • More severe, chronic and violent offending

29
Hares (2003) Psychopathy Checklist Revised
  • Glibness/ superficial charm
  • Grandiose sense of self worth
  • Pathological lying and deception
  • Conning/ manipulative/lack of sincerity
  • Lack of remorse or guilt
  • Lack of affect and emotional depth
  • Callous/ lack of empathy
  • Failure to accept responsibility for own actions
  • Lack of friends or interpersonal relationships
  • Stimulation seeking
  • Parasitic lifestyle
  • Poor anger control
  • Early behavioural problems
  • Lack of goals
  • Impulsivity
  • Irresponsible behaviour
  • Promiscuity
  • Early behavior problems lt 10 y.o.
  • Criminal behavior
  • Revocation of release
  • Criminal versatility

How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality

32
How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality
  • We beat it into our children (Eysencks).
    Predicts
  • Punishment based socialization strategies should
    be successful.
  • BUT they arent.

33
How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality
  • We beat it into our children (Eysencks). NO.
  • We tell it to our children (Schweder). Predicts
  • The moral/ conventional distinction should not
    exist.
  • BUT it does.

34
How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality
  • We beat it into our children (Eysencks). NO.
  • We tell it to our children (Shweder). NO.
  • We work it out as rational human beings
    (Kohlberg). Predicts
  • Individuals who dont understand the moral/
    convention distinction must show some form of
    impairment in rational thought. Prediction
    disconfirmed (Hare, Blair).
  • Individuals with some form of impairment in
    rational thought must show impairment in moral
    reasoning. No evidence of this found.

35
How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality
  • We beat it into our children (Eysencks). NO.
  • We tell it to our children (Shweder). NO.
  • We work it out as rational human beings
    (Kohlberg). NO.
  • We work it out through Theory of Mind. Predicts
  • -A population with pronounced Theory of Mind
    impairment (individuals with autism) should show
    profound difficulties with morality.

36
How does this moral deficiency develop in
psychopaths?
  • Possible pathways to morality
  • We beat it into our children (Eysencks). NO.
  • We tell it to our children (Shweder). NO.
  • We work it out as rational human beings
    (Kohlberg). NO.
  • We work it out through Theory of Mind.
  • Healthy individuals are predisposed to find the
    distress of others aversive. We learn to avoid
    actions associated with harm to others (Blair,
    1995). Predicts

37
Prediction 1 We find the distress of others
aversive.
  • Human work
  • Animal work

Prediction 2 If you have a population who fails
to find the distress of others aversive.
38
Individuals with psychopathy and the distress of
others.
  • Reduced autonomic responses to the distress of
    others (Aniskiewicz, 1979 House Mulligan,
    1976 Blair et al., 1997 Blair, 1999).

39
The amygdala and vmPFC
40
Prediction If the amygdala is necessary for
appropriate responding to the fear of others,
then children with psychopathic tendencies should
show problems in their amygdala response to
fearful faces (N 12)

42
Take home
  • Moral decision-making depends on several
    different neural systems
  • Emotion plays a much bigger role than
    traditionally thought in moral decision-making
  • Emotion is key in developing morality
  • The primacy of cognition in moral decision-making
    has been strongly questioned
  • Emotional control is the likely limiting
    developmental factor in moral behavior choices
  • Disruptions in certain neural networks can have
    important implications in the justice-system
