I find that my participants are getting fatigued and begin to lose focus about halfway through the task, which is problematic from a data integrity standpoint. I have taken a look at the script and can't seem to figure out how to reduce the number of trials to make the task run for a shorter length of time. Can anyone help me figure out what to modify in the script to do so? Thanks a million

To shorten that particular task, simply remove items from the set-size <list> elements:
**************************************************************************************************************
**************************************************************************************************************
Set Sizes for Letter Practice Phase
**************************************************************************************************************
**************************************************************************************************************
<list PracLetterSetSize>
/ items = (2,2,3,3)
/ selectionmode = sequence
/ selectionrate = trial
</list>
**************************************************************************************************************
**************************************************************************************************************
Set Sizes for Letter & Math Practice Phase
**************************************************************************************************************
**************************************************************************************************************
<list PracBothSetSize>
/ items = (2,2,2)
/ selectionmode = sequence
/ selectionrate = trial
</list>
**************************************************************************************************************
**************************************************************************************************************
Set Sizes for Letter & Math Test Phase
**************************************************************************************************************
**************************************************************************************************************
<list TestBothSetSize>
/ items = (3,3,3,4,4,4,5,5,5,6,6,6,7,7,7)
</list>
