4What 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

- Kohlbergs stages of moral development
- Obedience and Punishment

- Good Interpersonal Relationships

7What is morality?
- There are multiple systems engaged in a variety

cultural concept of morality (Turiel, Smetana,
Nucci, Haidt, Blair).

16Emotional Underpinnings
- Care-based
- Fear/distress of others
- Social Convention
- anger
- Disgust
- Disgust of others, taste/smell aversion
17Cognitive Underpinnings
- Emotional responses can explain badness, but
not wrongness (Nichols, 2002) - Theory of Mind
- Piaget
- Intention
- Children vs. adults
- Young et al. (2010)
18Trans-cranial Magnetic stimulation
19(No Transcript)
20Young et al., 2010
- By disrupting the Temporal-Parietal Junction,
intention information processing was disrupted
resulting in disrupted moral decision-making
21Emotional 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
22Engaging in Moral Behavior
- Emotional data is fed to the orbital-frontal
cortex (OFC)
23OFC
24Engaging 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
25Questions 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?
26Case Examples
- Care-based morality relies on the amygdala
- OFC is necessary to integrate emotional
information into decision-making - Pseudo-psychopathy
- OFC damage
- Psychopathy
27Pseudo-psychopathy
28Psychopathy
- Psychopathy is associated with (Frick White,
2008 White Frick, 2010) - Antisocial behavior
- Instrumental Aggression
- More severe, chronic and violent offending
29Hares (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

31How does this moral deficiency develop in
psychopaths?
- Possible pathways to morality
32How 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.
33How 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.
34How 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.
35How 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.
36How 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
37Prediction 1 We find the distress of others
aversive.
Prediction 2 If you have a population who fails
to find the distress of others aversive.
38Individuals 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).
39The amygdala and vmPFC
40Prediction 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)
41Questions 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?
42Take 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
