Hi,
I have an experiment where I have faces and scenes paired together. The pairing of the two are random, and should be random initially. However, participants will then need to see the same face-scene pair again later in the experiment. For instance, trials 1-4 could be four trial unique pairs, but trials 5-8 should be the repeats of trials 1-4 in a random order.
How do I save this random pair so that participants can learn these pairings?
Here is code I have so far.
************ Import Faces ************ <item Face> / 1 = "Faces/1.jpg" / 2 = "Faces/2.jpg" / 3 = "Faces/3.jpg" / 4 = "Faces/4.jpg" </item>
************* Locate Scenes ************* <include> / precondition = [mod(script.subjectid,6) == 1] / file = "scene_files_test/all1.txt" </include>
**************** Picture Elements **************** <picture face_pictured_2> / items = Face / position = (27%, 50%) / size = (50%, 50%) </picture> # one face and one scene next to each other (second part)
<picture scene1_display> / items = everything / position = (70%, 50%) / size = (50%, 50%) </picture> #for the scenes in the second part
*************** Creating Trials *************** <trial Face_and_Scene> / stimulustimes = [ 0 = face_pictured_2; 0 = scene1_display; ] / timeout = 5000 / validresponse = ("1", "2", "3") / inputdevice = keyboard </trial> # one face and one scene next to each other (second part)
*************** Creating Blocks *************** <block Study> / trials = [1-4 = Face_and_Scene] </block>
Any help is greatly appreciated!!
