Programming problem Iowa Gambling Task

[Angelique Cramer]

Dear sir/madam,

Currently I'm programming a Duch version of the Iowa Gambling Task in E-prime. The task does fine, but I have encountered a problem. I have made a DesignList with 100 trials and each trial refers to four nested lists: Deck A, Deck B, Deck C and Deck D. 

The problem is that I want the experiment to proceed as follows: for example, a subject picks 3 cards from Deck D (so the first 3 ID's from the Deck D list) and when he picks a card from Deck A for the fist time, I want the list to go to the first ID/trial of the Deck A list. Instead, the program goes to the fourth line of the Deck A list.

How can I program it so that the experiment proceeds according to the abovementioned?

Note that the available Iowa Gambling Task made in e-prime suffers from the same problem and if I understand the article about the original version correctly (Bechara et al., 1994), then you have to program the experiment so that you always begin with the first line/trial of the list and then proceed sequentially.

Thanks in advance for helping me out,

Best regards,

Angélique Cramer

Additional information:
- Designlist: 100 samples, 1 cycle, Nested: DeckA, DeckB, DeckC, DeckD
- DeckA/B/C/D: 40 samples per deck, attributes: win, loss
- TrialProc: game slide (four cards visble on the screen, request to pick a card from any of the four decks), InLine script (if strHit "DeckA" then Feedback.ActiveState = "FBA", same goes for the other four decks), Feedback slide with 4 possible active states (for example, for Deck A this is FBA with text: "You have won [WinA] and lost [LossA])

Thank you again for helping me,
