Dear Users,

I am trying to assign randomly an <item> element  I defined to the pictures /items elemend. The idea is that there are 4 different picture sets (PicsTwentyFour_1 etc.) and those sets should be presented randomly (noreplace) in each of the 4 trials. I thought about creating an <item> element and define the <item> pictures in there (see <item sets>), but I get the error:
"missing double quotes". Is there any way to randomly assign an <item> element to the /items property of the pictures?

The full code is below

<values>
/ current_trial = 0
/ answer_filename = ""
/ condition = 0
/ current_set = 0
</values>

<data>
/ columns = (script.subjectid, script.groupid, values.condition, values.answer_filename, values.current_trial, trial.TrialSix.latency, trial.TrialTwentyFour.latency)
</data>

/ fontstyle = ("Arial", 2.5%, false, false, false, false, 5, 0)
/ inputdevice = mouse
</instruct>

<block assignment>
/ preinstructions = (page.pre_page)

    if (script.groupid == 1) block.BlSix

No, you cannot assing <item> elements randomly to <picture> elements. What you need to do is work with *item numbers*.

All your items should be in a *single* <item> element. The respective item *numbers* are what make up a set as in

<item PicsTwentyFour>
/ 1 = "Schokolade/Set_1/3bit_1.jpg"
...
/ 24 = "Schokolade/Set_1/yorkie_2.jpg"

/ 25 = "Schokolade/Set_2/babyruth_1.jpg"
...
/ 48 = "Schokolade/Set_2/zero_1.jpg"

/ 49 = "Schokolade/Set_3/100grand.jpg"
...
/ 72 = "Schokolade/Set_3/yankie.jpg"

/ 73 = "Schokolade/Set_4/corny-big-schoko.jpg"
...
/ 96 = "Schokolade/Set_4/yogurette-300g.jpg"
</item>

<list PicSelectorTwentyFour_1>
/ items = (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24)
/ selectionrate = always
</list>

<list PicSelectorTwentyFour_2>
/ items = (25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48)
/ selectionrate = always
</list>

<list PicSelectorTwentyFour_3>
/ items = (49,...,72)
/ selectionrate = always
</list>

<list PicSelectorTwentyFour_4>
/ items = (73,...,96)
/ selectionrate = always
</list>

You can then draw the applicable item numbers from the respective set according to the set chosen:

<picture PTwentyFour_1>
/ items = PicsTwentyFour
/ select = list.chosenset.nextvalue
/ position = (10%,10%)
/ height = 20%
/ width = 20%
</picture>

...

with

<list chosenset>
/ items = (list.PicSelectorTwentyFour_1.nextvalue, list.PicSelectorTwentyFour_2.nextvalue, list.PicSelectorTwentyFour_3.nextvalue, list.PicSelectorTwentyFour_4.nextvalue)
...
</list>


Here's a minimal example to illustrate:

<block myblock>
/ trials = [1-2 = mytrial]
</block>

<values>
/ setnumber = 0
</values>

<trial mytrial>
/ ontrialbegin = [values.setnumber = list.setnumber.nextvalue; ]
/ stimulusframes = [1=s1,s2,s3,s4]
/ validresponse = (57)
</trial>

<text s1>
/ items = allitems
/ select = list.chosenset.nextvalue
/ position = (20%, 50%)
</text>

<text s2>
/ items = allitems
/ select = list.chosenset.nextvalue
/ position = (40%, 50%)
</text>

<text s3>
/ items = allitems
/ select = list.chosenset.nextvalue
/ position = (60%, 50%)
</text>

<text s4>
/ items = allitems
/ select = list.chosenset.nextvalue
/ position = (80%, 50%)
</text>

<item allitems>
/ 1 = "A1"
/ 2 = "A2"
/ 3 = "A3"
/ 4 = "A4"

/ 5 = "B1"
/ 6 = "B2"
/ 7 = "B3"
/ 8 = "B4"
</item>

<list set1>
/ items = (1,2,3,4)
/ selectionrate = always
</list>

<list set2>
/ items = (5,6,7,8)
/ selectionrate = always
</list>

<list setnumber>
/ items = (1,2)
</list>

<list chosenset>
/ items = (list.set1.nextvalue, list.set2.nextvalue)
/ selectionrate = always
/ selectionmode = values.setnumber
</list>

Thank you so much, Dave. It didn't occur to me that selectionmode can also evaluate in an integer to be chosen.

Thanks again,
Chris
