Pre-sentiment in IOWA Gambling task?

How do we measure presentiment:

  • Anticipation of a random event (feedback)
  • Two potential outcomes
  • One good, one bad
  • But wait a moment.......

    There are winning and loosing cards in all the decks!

    So: Do not average SC over bad en good decks but over the winning and loosing cards within the decks!
