1 Decisions and Free Will Choosing to act on basis of desires (immediate automatic goals) Choosing to act on basis of desires and values (immediate and deferred automatic goals) Choosing to act on basis of rational mind (independent agency)

2 Agency Free choices Influenced choices Automatic response, reflexes, hemiballismus, tourettes, tics, temporal lobe seizures, sleep walking, stereotype behavior Combinations

3 Two Basic Philosophies Determinism, fatalism as described by Laplace (and many others) Free Will is possible,Aristotle, Descartes Two subtypes,Compatibilism and Non Compatibilism John Searle : Mind, A Brief Introduction, Ch 8

4 Legal/Moral Responsibility Aristotle’s Conditions: Control and Knowledge McNaughton Rule: Knowledge of what he was doing and knowledge that it is wrong(mid 19 th century) Modified McNaughton: added component of control (end 19 th century) Model Penal Code: substantial incapacity to know right from wrong, or irresistible urge (1962) Post Hinckley: urge removed and placed burden on defendant (1984)

5 Phenomenon of Will Intuitively present but affected by conscious factors: coersion, impulses, emotions, mental illness. Attentuating circumstances? Are there unconscious factors? Freudian slips, id conflicts, mental illness, subliminal effects? Churchland Hypothesis of control space

6 Neuroscience of Conscious Will Libet Experiment 1983 http://uk.youtube.com/watch?v=fI1624SwY nIhttp://uk.youtube.com/watch?v=fI1624SwY nI Haynes Experiment 2008 http://www.wired.com/science/discoveries/ news/2008/04/mind_decision#

7 Explanations Libet: perhaps the real choice is to decide in the negative “free won’t” Methodological: timing, repeatability, generalisability Preconscious “I” Wegner: conscious illusion

8 Decisions Mental process leading to choice or opinion Conscious rational process weighing pro and con and likelihoods Emotional process (Damasio) Unconscious forces (internal and external)

9 Defective Decisions Wrong information Defective reasoning (irrationality) Cognitive Bias Beliefs Emotionality (fear) Unconscious effects (sexism, racism, other)

10 Neuroscience Decisions Cortical activation with linkage to lower emotional systems fMRI studies:ethical, marketing, bias, style for choosing, political orientation, mate selection, etc Some examples influences: MAO subtypes, oxytocin receptors, psychopaths, drugs

11 Political Orientation Amodio et al : 2007 Nature Neuroscience Brain activation in Go/NoGo decisions Alford et al 2008 Science Political attitudes affected by physiological traits Fowler et al 2008 Variant of dopamine related to liberal attitudes
