Hello,
I'm doing some research in which participant i asked to response "if any of 4 faces is different from the others". For now it was pretty easy, because they could have chose only "p" if one of them is different or "q" if all of them are the same.
Now I want to precise which of 4 faces is different, and participant will be asked to click on the face they think is different. So I think about putting 4 rectangle shapes on the picture and want to know only, which rectangle they chose. It's kind a face in the crowd task, but i've seen the script and it doesn't fit mine.
Down below you can see an ex. of a trial and picture, that is one of the tasks.
<trial agency_minus>
/ stimulustimes = [1=fiksacja; 2000=noreplace(1_agency_minus, 2_agency_minus, 3_agency_minus, 4_agency_minus, 5_agency_minus, 6_agency_minus, 7_agency_minus, 8_agency_minus, 9_agency_minus, 10_agency_minus, 11_agency_minus, 12_agency_minus, 13_agency_minus, 14_agency_minus, 15_agency_minus, 16_agency_minus)]
/ validresponse = lbuttondblclk
/ inputdevice = mouse
</trial>
I'll be glad for any suggestion and help :)
Thank You!
