Hello,
I would like to have inquisit randomly select the text colour for a text element for a given trial, which will either be red or green. It needs to be random selection but for each trial type I should be able to have half of the trials in red letters and half in green letters.
Is there something I can do with the /txcolor attribute or do I need to add some kind of dependency for /select? I am not sure how to do this.
I was thinking I may need to individually program the red and green trials and then do this using noreplace selection for the blocks, but that becomes very tedious because I have a lot of different trial types.
Any help would be appreciated.
Thanks

You can do that using a <list> and some /ontrialbegin logic:
<block myblock>
/ trials = [1-4=mytrial]
</block>
<trial mytrial>
/ ontrialbegin = [text.mytext.textcolor=list.mylist.nextvalue]
/ stimulusframes = [1=mytext]
/ validresponse = (57)
</trial>
<text mytext>
/ items = ("A", "B", "C", "D")
</text>
<list mylist>
/ items = (red, red, green, green)
</list>
