Title: Non Conscious Processes preceding Intuitive decisions
1Non Conscious Processes preceding Intuitive
decisions
- Dick J. Bierman
- University of Amsterdam
- Utrecht University
2Intuition in this talk
- The ability to make a profitable decision without
full rational analysis sometimes associated with
a gut-feeling. - Often if problems are underspecified or under
time pressure.
3Why Intuition?
- In the management literature it is claimed that
intuition is an important individual property. - Example The role of intuition in strategic
decision making ( Human Relations, 53 (1) 57-86) - Conclusion .Use of intuitive synthesis was
found to be positively associated with
organizational performance in unstable
environment, but negatively in stable environment
4Assessment
- Is there a valid assessment instrument?
- Questionaires are too obvious
- Needed a covert instrument based upon a model of
intuition
5Intuition in Science
- Behaviorism
- Decision without reason
- Cognitive Science
- de Groot The thinking of the Chess Player
- Simon Chunking (Anderson)
- Cognitive Neuro Science
- Damasios somatic marker -gt model

YES!
9Damasios Somatic Marker model
Previous problem
Current similar problem
Previous decision (selection of alternative)
NC Reduction of Alternatives
Good or Bad outcome
Somatic Marking Of Decision (nc emotion)
Current decision
10The 3 factors of Intuition
- Implicit Learning (from previous experiences)
- Development of Somatic marker
- Listening to Somatic marker (giving rise to
advantageous decisions)
11Qualitative research Chess Player
- Automatic selection of a reduced set of
alternatives - Feels bad/good argument
12Lab research
- Damasio Gambling task. Choosing the good deck.
- Somatic marker Skin Conductance
13Damasio gambling procedure
- Participant gets initially 2000
- Draws cards from one of 4 different decks
- Two decks are good and 2 decks are bad
- Card is either winning or losing
Preparation
Skin Conductance

14Results Damasios Gambling experiment
-
- Increase of SM preceding incorrect decisions
before knowledge is explicit. - The body (GUT) knows what your cognition
doesnt know yet. - Not for subjects with prefrontal cortex damage
15Less attractive aspects of Gambling Task
- Implicit learning is too simple
- Factor of Listening to Somatic Marker cannot be
measured through slow Skin Conductance - So
- New task Artificial Grammar task
- New dep. Variable Pupil Dilation

SM drives the decision
20Top manager Nina Brink
- World On Line (brings shares to the market)
- Why did Nina Brink sell all her shares before day
1? Foreknowledge? - She did it again later, gues when?
21Is intuition also driven by the actual future

23Testing Pre-sentiment
- ....Artificial divination makes predictions by
argument, concluding upon signs and tokens
Natural divination forms a presage from an
inward presentiment of the mind, without the help
of signs.... From Francis Bacon, On the dignity
and the advancement of learning", book IV Chap
III - Anticipation of a random event
- Two potential outcomes
- One good, one bad
- Eg. Presentation of random positive and negative
pictures but also presentation of random winning
and loosing cards!

30Unified Intuition paradigm(include Presentiment)
- Manipulate the future randomly
- Is possible by having two reinforcements eg -10
euro and -100 euro randomly selected. - Manipulation is not as strong as
neutral-emotional pictures

- Intuition assessment instrument (4 factors)
- Implicit learning
- Somatic marker
- Listening to SM
- Pre-sentiment
- Intuition training
- bio feedback of Somatic Marker
33Related to intuition

- Non conscious information is genetic
- Creativity
- Emotional biasing of search space is driven by
aesthetics
