Introduction
Self-control is everywhere
Lack of self-control considered major social problem
1994 2011 2012 Nov 2013 1990
Is there a parental responsibility to install self-control in children?
If so, what does it entail?

Introduction
Overview
1. Recent studies on the relevance of self-control
2. Recent neurobiological/genomics research
3. Apparent conclusion: Raising self-controlled children to achieve health, wealth and public safety
4. Raise what?
1. Self-control as goal-achievement: Willpower versus self-control skills
2. The self of self-control: Self-control as goal-construction and -evaluation
5. Neuroscience and new parental responsibilities?
6. Conclusion

1. Recent studies on the relevance of self-control
Child self-control at 3 years predicts:
- Physical health
- Substance dependence
- Personal finances
- Criminal offending outcomes
40 years later

2. Neurobiological/genomics research
Neuroscience (selection)
Emerging understanding of neuropsychological bases of self-controlled behaviour (domain-general framework)
Lesions studies [in children]:
- Distinct developmental differences after prefrontal lesions - Altered integration and interplay of various deficits that contribute to frontal
lobe syndromes
Functional neuroimaging studies (fMRI) - Goal-directed decisions basis in a signal encoded in ventromedial PFC - Exercising self-control: modulation of the signal by dorsolateral PFC - Differences in vmPFC activities in dieters & non-dieters - Methamphetamine abusers specific self-control deficits in motor, cognitive
and affective control and structural differences in ventrolateral PFC - Inhibitory control recruits an interacting network of brain-regions

2. Neurobiological/genetics research
Genetics (selection)
Heritability studies
Genetic influence on personality traits, psychological interest, social attitudes
Molecular genetics (candidate genes)
Monoamine oxidase-a genetic variations influence brain activity associated with inhibitory control
Polymorphism of the COMT gene (affects dopaminergic neurotransmitter system) associated with differences in the prefrontal executive control network
Department Health, Ethics, and Society Dorothee Horstkötter

3. Apparent conclusion: Raise self-controlled children
Policy implications (Moffitt et al.)
- Install early intervention programs for young children
- Interventions in adolescence to prevent/ameliorate mistakes
- Support self-controlled decisions by opt-out programs (default does not require ‘difficult’ self-control)
- Policy interventions to render self-control superfluous
- Policy interventions to make self-controlled decisions more easy (ban cigarettes, obligation to wear safety bells, etc)

3. Apparent conclusion: Raise self-controlled children
Intervention implications (Berkman, Graham & Fisher, 2012)
Focus on young children (more amendable to intervention)
Focus on one particular aspect of self-control (yield success in others too)
Improve self-control precondition for additional interventions
FMRI studies to test intervention readiness or gains related to self-control
Targeted intervention that specifically activate specific brain regions considered relevant for self-control tasks

3. Apparent conclusion: Raise self-controlled children
Parenting implications ?
- Relevance of early childhood
- Implications for the meaning of ‘good parenthood’
- Parental responsibility to install/foster self-control in children and safeguard their future health, wealth and law-abidingness
Raising self-controlled children !?

4. Varieties of self-control
Self-control in social psychology
“Self-control involves the ability to prevent or override unwanted thoughts, behaviours and emotions”
(Muraven, Baumeister & Tice 1999)
Department Health, Ethics, and Society Dorothee Horstkötter

4. Varieties of self-control
Self-control in social psychology
“Self-control involves the ability to prevent or override unwanted thoughts, behaviours and emotions”
(Muraven, Baumeister & Tice 1999)
Focus 1: prevent or override

4. Varieties of self-control
Self-control in social psychology
“Self-control involves the ability to prevent or override unwanted thoughts, behaviours and emotions”
(Muraven, Baumeister & Tice 1999)
Focus 1: prevent or override
Focus 2: unwanted
Different implications regarding parental responsibility

4. Varieties of self-control
Self-control in social psychology (prevent and override)
Self-control tests typically psychological tests
1) Test children’s capacity to delay gratification.
2) Test differences in self-control in subsequent self-control tasks
Commonalities
Pre-given goal, self-control supports goal-achievement/overcome temptation
Differences
Willpower, mental strength, mental muscle versus Strategy, skill, plan, etc.
Department Health, Ethics, and Society Dorothee Horstkötter

4. Varieties of self-control
Self-control in social psychology (prevent and override)
Self-control as control of the self by the self
Willpower/Self-control skill: control of the self (self the object of self-controlled behavior)
Self-control as control by the self?
Not goal-achievement, but goal-setting/-construction/-evaluation
Self as the subject of self-controlled behavior
Department Health, Ethics, and Society Dorothee Horstkötter
16
4. Varieties of self-control
Self-control in social psychology and neuroscience
Self-control studies in neuroscience sole focus on strength model
Self-control to achieve pre-set goals
Normative value of these goals!
Source of this normative value?
Tension goal-achievement versus goal-adjustment
Reasons needed for the one or the other
The self: control by the self
Department Health, Ethics, and Society Dorothee Horstkötter
17
4. Varieties of self-control
Self-control in social psychology (unwanted)
i) Self-determination theory
Control versus self-determination
Assumption: controlled action less successful than self-determined action (goals the value of which one appreciates and which constitute a reason to achieve it)
ii) Self-control versus self-regulation
Self-regulation maintaining one’s action in line with one’s integrated self
Current neuroscience research pays no attention to these understandings of self-control

5. Neuroscience and new parental responsibilities?
Parental responsibilities and self-control
Educational goals I
- Obedience
- Ability to accept and follow externally-set rules
- Suppress impulses, ‘first order desires’
Educational goals II
- Become autonomous person
- Develop ‘second order desires’
- Develop a self/personality
- Become able to set goals (for reasons)
- Evaluate goals (achievable, desireable)
Department Health, Ethics, and Society Dorothee Horstkötter

5. Neuroscience and new parental responsibilities?
Neuroscience on self-control and parental responsibilities
It depends:
Educational goals I: Maybe
Educational goals II: No

5. Neuroscience and new parental responsibilities?
Neuroscience on self-control and parental responsibilities
It depends:
Educational goals I: Maybe
Educational goals II: No
- Empirical question whether/how exactly parenting (and interventions in parenting) makes a difference in the neurobiological development of the brains of children.
- Brain training interventions, emerging evidence, currently tested
- Remaining challenge: Invoke self-control for which goals?
- Parental responsibility: raising children to achieve distant goals goes together with care to not install too much (rigidity) or errant self-control (for bad goals)
Department Health, Ethics, and Society Dorothee Horstkötter

5. Neuroscience and new parental responsibilities?
Neuroscience on self-control and parental responsibilities
It depends:
Educational goals I: Maybe
Educational goals II: No
Not investigated by current neurosciences
Not investigatable by current/future neuroscience
[There probably is a parental responsibility to raise autonomous children, yet no implications regarding this responsibility because of recent findings in neuroscience]
Fundamental normative questions which goals to go for and why.
Department Health, Ethics, and Society Dorothee Horstkötter

6. Conclusion
Neuroscience and genomics research potentially relevant for insight into the generation of human behavior.
Also more detailed evidence in this regard, will not establish a direct link on how to raise our children
Remains a normative rather than a biological question.
... Only, after the normative question has been addressed, neuroscience might be invoked to achieve what is considered desirable.
“Which thoughts, behaviors and emotions are undesirable and ought to be prevented or overridden”
