Hello!
How can I give half of my trials a certain marker (such as "same category") and the other half a different marker (such as "different category") and then have that information available in my data file--so I can sort the trials according to these two different markers?
Does this make sense?
Thanks!

Suppose you have two "same category" <trial> elements , and two "different category" <trial> elements.
Set up a <values> entry:
<values>
/ category = ""
...
</values>
and set that value to the appropriate label in your trials:
<trial same_a>
/ ontrialbegin = [values.category = "same category"]
...
</trial>
<trial same_b>
/ ontrialbegin = [values.category = "same category"]
...
</trial>
<trial different_a>
/ ontrialbegin = [values.category = "different category"]
...
</trial>
<trial different_b>
/ ontrialbegin = [values.category = "different category"]
...
</trial>
Specify the <data> element in the script to log the respective value:
<data>
/ columns = [date time subject group blocknum blockcode trialnum trialcode response latency correct ... values.category]
...
</data>
You can then sort by values.category as needed.
