Hi,
I want to change one thing in BART script for one of my conditions. In each pump the potential earnings increases, so the selectedcount of list.pumpresult*0.5.
<list pumpresult>
/items = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20,
21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
/replace = false
</list>
Note:
* selects with no replacement a digit from 1 to 32
* with each selection the likelihood to sample the "1" increases slightly
* If "1" is sampled -> balloon pops
<expressions>
/ pumpvalue = format("%.2f", values.pumpvalue)
/ totalearnings = format("%.2f", values.totalearnings)
/ potentialearnings = format("%.2f", (list.pumpresult.selectedcount - 1) * .05)
</expressions>
In one of the conditions, however, I want the participants start with already selected 7 pumps, so that the potential earnings will be displayed as 6*.05, and the pump count will be displayed as 7 in the begining of the task (witout them selecting, autamatically selected by inquisit).
Is it possible to program it like this? If so could you give me a hint on how to do it?
