Dear all,
I'm currently pretty stuck at the randomization of my experiment. There are two main problems:
1) I have two picture pools, <item Suchbild> with items from SB1A, SB1B, SB2A...SB5B, and <item Zielreiz> with 5 pictures ZR1..ZR5. I want to randomly present one of the Zielreiz first, then present a Suchbild. The problem is that I have to link the Zielreiz to the Suchbilder. So, if ZR1 is shown, SB1A or SB1B has to be shown after, for ZR2 it has to be SB2A or SB2B etc. I thought adding a copy of each ZR to the item list, so that there is a clear one-to-one connection for each Zielreiz and Suchbild.
Now my beginner's question is, is there a "if..then" command or any other way I gotta work around the issue? (And is it correct to set the randomization at the <picture..> level, not the <trial..>?)
<item Zielreiz>
/1 = "ZR1.jpg"
/2 = "ZR2.jpg"
/3 = "ZR3.jpg"
/4 = "ZR4.jpg"
/5 = "ZR5.jpg"
</item>
<picture Zielreiz>
/items = Zielreiz
/select = noreplace
/position = (50, 50)
</picture>
<item Suchbild>
/1 = "SB1A.jpg"
/2 = "SB1B.jpg"
/3 = "SB2A.jpg"
/4 = "SB2B.jpg"
/5 = "SB3A.jpg"
/6 = "SB3B.jpg"
/7 = "SB4A.jpg"
/8 = "SB4B.jpg"
/9 = "SB5A.jpg"
/10 = "SB5B.jpg"
</item>
<picture Suchbild>
/Items = Suchbild
/select = if ....
</picture>
2) A third picture pool, <item Alternative> with NA1..NA5 should be shown after each ZRx-SBxx-trial. My problem is, that I have to show the same picture twice, so NAx for 1 sec, then a fixation cross, then the same NAx for another five seconds. My idea is to set a second Alternative 2, which selects the current Alternative (1) picture. Does this work or is there a possibility to set the /select = noreplace to pick a picture twice, then go on with selecting a different one?
Rudimentally, it would look like this:
<item Alternative>
/1 = "NA1.jpg"
/2 = "NA2.jpg"
/3 = "NA3.jpg"
/4 = "NA4.jpg"
/5 = "NA5.jpg"
</item>
<picture Alternative>
/items = Alternative
/select = noreplace
/position = (50, 50)
</picture>
<picture Alternative 2>
/items = Alternative
/select = current
/position = (50, 50)
</picture>
Thank you so much in advance!

If I understand you correctly, you'll simply want to pair your "Suchbild" <picture> elements to your "Zielreiz" <picture>:
https://www.millisecond.com/support/docs/v4/html/howto/howtopairs.htm
In a nutshell, I'd do something like this:
<values>
/ zielitem = 1
/ suchitem = 1
</values>
<block exampleblock>
/ trials = [1-5 = exampletrial]
</block>
<trial exampletrial>
/ ontrialbegin = [values.zielitem = list.zr_itemnumbers.nextindex;
values.suchitem = values.zielitem + list.version.nextvalue;]
/ stimulustimes = [0=zielreiz; 2000=suchbild]
/ validresponse = (57)
</trial>
<list zr_itemnumbers>
/ poolsize = 5
</list>
<list version>
/ items = (0,5)
/ replace = true
</list>
<item Zielreiz>
/1 = "ZR1.jpg"
/2 = "ZR2.jpg"
/3 = "ZR3.jpg"
/4 = "ZR4.jpg"
/5 = "ZR5.jpg"
</item>
<text Zielreiz>
/items = Zielreiz
/select = values.zielitem
/position = (50, 50)
</text>
<item Suchbild>
/1 = "SB1A.jpg"
/2 = "SB2A.jpg"
/3 = "SB3A.jpg"
/4 = "SB4A.jpg"
/5 = "SB5A.jpg"
/6 = "SB1B.jpg"
/7 = "SB2B.jpg"
/8 = "SB3B.jpg"
/9 = "SB4B.jpg"
/10 = "SB5B.jpg"
</item>
<text suchbild>
/ items = suchbild
/ select = values.suchitem
</text>
Or, if you'd rather keep things a bit simpler, you could set up two separate trials (one for version a, one for version b) and then sample from those trials randomly at the block-level:
<block exampleblock>
/ trials = [1-5 = replace(a,b)]
</block>
<trial a>
/ stimulustimes = [0=zielreiz; 2000=suchbilda]
/ validresponse = (57)
</trial>
<trial b>
/ stimulustimes = [0=zielreiz; 2000=suchbildb]
/ validresponse = (57)
</trial>
<item Zielreiz>
/1 = "ZR1.jpg"
/2 = "ZR2.jpg"
/3 = "ZR3.jpg"
/4 = "ZR4.jpg"
/5 = "ZR5.jpg"
</item>
<text Zielreiz>
/items = Zielreiz
/select = noreplace
/position = (50, 50)
</text>
<item SuchbildA>
/1 = "SB1A.jpg"
/2 = "SB2A.jpg"
/3 = "SB3A.jpg"
/4 = "SB4A.jpg"
/5 = "SB5A.jpg"
</item>
<item SuchbildB>
/1 = "SB1B.jpg"
/2 = "SB2B.jpg"
/3 = "SB3B.jpg"
/4 = "SB4B.jpg"
/5 = "SB5B.jpg"
</item>
<text suchbildA>
/ items = suchbildA
/ select = text.zielreiz.currentindex
</text>
<text suchbildB>
/ items = suchbildB
/ select = text.zielreiz.currentindex
</text>
And if you want some balance between versions (e.g. either 3 trials of version A and 2 trials of version B or vice versa), you can do
<block exampleblock>
/ trials = [1-4 = noreplace(a,b); 5 = noreplace(a,b)]
</block>

Dear Dave,
We slightly changed our design and I am in need of your help once again.
I have two sets of stimuli, (itemlists) ZR and NA, with Zielreiz and Suchbild linked as above: If Zielreiz1 is selected, it should accordingly select Suchbild1.
Now, however, we have two versions of each Zielreiz and Suchbild - ZR and NA. It should randomly select from either ZR or NA item but if it selects item 1 from ZR it should never select item 1 from NA.
It should work as a linked either-or condition so to say. Is that possible?
Thanks a lot in advance!
Best regards,
Rebsu

It should randomly select out of the Zielreiz or Alternative Item which is linked to the SuchbildZ item if Zielreiz is selected and to the SuchbildN item if Alternative is selected. If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k.
In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation.
As I said, I am not sure if this choice of itemslists is the best way to do it, if it's better to pair ZR1 and NA1, ZR2 and NA2 etc. and then let inquisit choose between these pairs, consequtively linking them again to ZR1 or NA1, if there is a good way to do it at all or if pseudorandomizations with different groups where it is preselected if which SuchbilZ and which SuchbildN are randomly presented are way easier.

Sorry, I'm having trouble making sense of the description, particularly this part: "If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k.
In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation."
> "If it selects ZR1 (consecutively AZ1) [...] "
#1: What does "consecutively" mean here?
> "If it selects ZR1 [...] it must always also select ZR2"
#2: Why must ZR2 be selected if ZR1 has been selected?

+x+x+x+xDear Dave, We slightly changed our design and I am in need of your help once again. I have two sets of stimuli, (itemlists) ZR and NA, with Zielreiz and Suchbild linked as above: If Zielreiz1 is selected, it should accordingly select Suchbild1. Now, however, we have two versions of each Zielreiz and Suchbild - ZR and NA. It should randomly select from either ZR or NA item but if it selects item 1 from ZR it should never select item 1 from NA. It should work as a linked either-or condition so to say. Is that possible? Thanks a lot in advance! Best regards, Rebsu Please provide the code. <item Zielreiz> /1 = "ZR1.jpg" /2 = "ZR1k.jpg" /3 = "ZR2.jpg" /4 = "ZR2k.jpg" /5 = "ZR3.jpg" /6 = "ZR3k.jpg" /7 = "ZR4.jpg" /8 = "ZR4k.jpg" /9 = "ZR5.jpg" /10 = "ZR5k.jpg" /11 = "ZR6.jpg" /12 = "ZR6k.jpg" /13 = "ZR7.jpg" /14 = "ZR7k.jpg" /15 = "ZR8.jpg" /16 = "ZR8k.jpg" /17 = "ZR9.jpg" /18 = "ZR9k.jpg" /19 = "ZR10.jpg" /20 = "ZR10k.jpg" </item> <picture Zielreiz> /items = Zielreiz /select = noreplace /position = (50, 50) </picture> <item Alternative> /1 = "NA1.jpg" /2 = "NA1k.jpg" /3 = "NA2.jpg" /4 = "NA2k.jpg" /5 = "NA3.jpg" /6 = "NA3k.jpg" /7 = "NA4.jpg" /8 = "NA4k.jpg" /9 = "NA5.jpg" /10 = "NA5k.jpg" /11 = "NA6.jpg" /12 = "NA6k.jpg" /13 = "NA7.jpg" /14 = "NA7k.jpg" /15 = "NA8.jpg" /16 = "NA8k.jpg" /17 = "NA9.jpg" /18 = "NA9k.jpg" /19 = "NA10.jpg" /20 = "NA10k.jpg" </item> <picture Alternative> /items = Alternative /select = noreplace /position = (50, 50) </picture> <picture Alternative_2> /items = Alternative /select = current (alternative) / position = (50, 50) </picture> <item SuchbildZ> /1 = "AZ1.jpg" /2 = "BZ1.jpg" /3 = "AZ2.jpg" /4 = "BZ2.jpg" /5 = "AZ3.jpg" /6 = "BZ3.jpg" /7 = "AZ4.jpg" /8 = "BZ4.jpg" /9 = "AZ5.jpg" /10 = "BZ5.jpg" /11 = "AZ6.jpg" /12 = "BZ6.jpg" /13 = "AZ7.jpg" /14 = "BZ7.jpg" /15 = "AZ8.jpg" /16 = "BZ8.jpg" /17 = "AZ9.jpg" /18 = "BZ9.jpg" /19 = "AZ10.jpg" /20 = "BZ10.jpg" </item> <picture SuchbildZ> /Items = SuchbildZ /select = picture.zielreiz.currentindex /size = (95%, 95%) /position = (54, 50) </picture> <item SuchbildN> /1 = "AN1.jpg" /2 = "BN1.jpg" /3 = "AN2.jpg" /4 = "BN2.jpg" /5 = "AN3.jpg" /6 = "BN3.jpg" /7 = "AN4.jpg" /8 = "BN4.jpg" /9 = "AN5.jpg" /10 = "BN5.jpg" /11 = "AN6.jpg" /12 = "BN6.jpg" /13 = "AN7.jpg" /14 = "BN7.jpg" /15 = "AN8.jpg" /16 = "BN8.jpg" /17 = "AN9.jpg" /18 = "BN9.jpg" /19 = "AN10.jpg" /20 = "BN10.jpg" </item> <picture SuchbildN> /Items = SuchbildN /select = picture.alternative.currentindex /size = (95%, 95%) /position = (54, 50) </picture> <item ZrWahl> /1 = "ZR1.jpg" /2 = "ZR2.jpg" /3 = "ZR3.jpg" /4 = "ZR4.jpg" /5 = "ZR5.jpg" /6 = "ZR6.jpg" /7 = "ZR7.jpg" /8 = "ZR8.jpg" /9 = "ZR9.jpg" /10 = "ZR10.jpg" </item> <item NaWahl> /1 = "NA1.jpg" /2 = "NA2.jpg" /3 = "NA3.jpg" /4 = "NA4.jpg" /5 = "NA5.jpg" /6 = "NA6.jpg" /7 = "NA7.jpg" /8 = "NA8.jpg" /9 = "NA9.jpg" /10 = "NA10.jpg" </item> <picture ZrWahl> / items = ZrWahl / hposition = list.hpos.nextvalue </picture> <picture NaWahl> / items = NaWahl / hposition = list.hpos.nextvalue </picture> <list hpos> / items = (30%, 70%) / selectionrate = always </list> <trial Suche> /stimulustimes = [0=blank, fixation, ziellabel; 500=Zielreiz, ziellabel; 1500=blank, fixation; 2000=Suchbild; 6000=blank ;6001=Suchinstruktion] /validresponse = ("t", "z", "g", "h", " ") </trial> <trial AltPresentation> /stimulustimes = [0=Alternative, reset; 1000=blank, fixation; 1500=Alternative_2, reset; 5500=blank, warten] /response = timeout (6500) </trial> (trials are still from the old version, so definitely not correct yet) This is the current state. I am not sure if this is the best way to build up the whole thing, though. Basically, I have pairs of pictures - the A_(Z or N)_1 and B_1 version. It should randomly select out of the Zielreiz or Alternative Item which is linked to the SuchbildZ item if Zielreiz is selected and to the SuchbildN item if Alternative is selected. If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k. In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation. As I said, I am not sure if this choice of itemslists is the best way to do it, if it's better to pair ZR1 and NA1, ZR2 and NA2 etc. and then let inquisit choose between these pairs, consequtively linking them again to ZR1 or NA1, if there is a good way to do it at all or if pseudorandomizations with different groups where it is preselected if which SuchbilZ and which SuchbildN are randomly presented are way easier. Sorry, I'm having trouble making sense of the description, particularly this part: "If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k.

Sorry for the confusing description. The code is only half-finished because I don't know how to continue, so it's definitely not clear from the code, you are right. I think I got a typo in there with #2 and #3. It should be: if ZR1 is selected, ZR1k must also always be selected (consecutively BZ1).
What I'm trying to do is the following:
Choose one item of either <item Zielreiz> or <Item Alternative>. If it chooses item 1 of Zielreiz (ZR1), it should then choose the according (numberwise) item of SuchbildZ, either version A (AZ1) or version B (BZ1), and the other, not chosen version (A or B), must be chosen at some point in the trial, too after ZR1k (which is just a copy of ZR1) was chosen. At the same time ZR1 should be eliminated as an option to choose from in <trial AltPresentation> and NA1 together with AN1 and BN1 should be eliminated as options in <trial Suche>. So it's always either ZR1 or NA1; ZR2 or NA2...
Later, in <trial Wahl> there should always be one picture which was chosen in <trial Suche> next to one picture which was chosen in <trial AltPresentation> but never two pictures which were chosen in the same trial. And I need to know which picture was chosen for which trial, so this must be possible to see in the data.
So, designwise following interrelations arise:
- ZR1=ZR1k (I did the copies because the same picture in <trial altpresentation> has to be shown twice (with a fixation cross in the middle) and it seemed the easiest solution I was actually able to programm at that time).
- ZR1=ZR1k are linked to AZ1 and BZ1. NA1=NA1k are linked to AN1 and BN1. NA2=NA2k are linked to AN2 and BN2, and so on.
- If ZR1 is chosen in <trial Suche>, ZR1k must also be chosen in <trial Suche>.
- ZR1 and NA1 are counterparts - if ZR1 is chosen in <trial Suche>, NA1 should be eliminated for <trial Suche> but be presented in <trial AltPresentation>.
= Everything from <item Zielreiz> and <item Alternative> chosen for <trial Suche> should be eliminated as an option to choose from in <trial AltPresentation>
- In <trial Wahl> there must always be one of <item Zielreiz> or <item Alternative> which was chosen in <trial Suche> next to one of <item Zielreiz> or <item Alternative> chosen in <trial AltPresentation>.
- Only one of ZR1 or ZR1k should be chosen in <trial Wahl> (There's probably an easier way to show the same picture twice in <trial AltPresentation> where I can delete all the ZR_k copies I assume?)
So what I basically need is a "if...then not.." and work with differents lists, right? I'm totally lost since I'm an absolute beginner :S
The other option is always doing different groups where it is clear if ZR1 or NA1 is chosen in the <trial Wahl>, maybe that's just the better alternative here?

What do you consider to be a "trial" in the above?

I am not sure if this is the best way to build up the whole thing, though. Basically, I have pairs of pictures - the A_(Z or N)_1 and B_1 version. It should randomly select out of the Zielreiz or Alternative Item which is linked to the SuchbildZ item if Zielreiz is selected and to the SuchbildN item if Alternative is selected. If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k. In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation. As I said, I am not sure if this choice of itemslists is the best way to do it, if it's better to pair ZR1 and NA1, ZR2 and NA2 etc. and then let inquisit choose between these pairs, consequtively linking them again to ZR1 or NA1, if there is a good way to do it at all or if pseudorandomizations with different groups where it is preselected if which SuchbilZ and which SuchbildN are randomly presented are way easier. Sorry, I'm having trouble making sense of the description, particularly this part: "If it selects ZR1 (consecutively AZ1) it must always also select ZR2 as well (consecutively BZ1) but must not select NA1 and NA1k. In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation." > "If it selects ZR1 ( consecutively AZ1) [...] " #1: What does "consecutively" mean here? > "If it selects ZR1 [...] it must always also select ZR2" #2: Why must ZR2 be selected if ZR1 has been selected? > "it must always also select ZR2 as well (consecutively BZ1)" #3: Why and in what way is ZR2 tied to BZ1? This doesn't seem to follow from the code at all. #4: What is the purpose of these <picture> elements? They don't appear to be used in the code you provided. <picture ZrWahl> / items = ZrWahl / hposition = list.hpos.nextvalue </picture> <picture NaWahl> / items = NaWahl / hposition = list.hpos.nextvalue </picture> > "In the AltPresentation trial it should then always select the not-chosen version of ZR_ or NA_. So, if in the Such-trial ZR1 is chosen, it should choose AZ1 and ZR1k+BZ1 in the Such-trial as well, and then choose NA1 in the AltPresentation" #5: What is the relationship between your "Such-trial" and "AltPresentation"? Since there is nothing in the code that actually runs these trials (i.e. a <block>), it's not clear at all how those trials do or do not interrelate. The shorter description you posted previously seems clearer ("[...] we have two versions of each Zielreiz and Suchbild - ZR and NA. It should randomly select from either ZR or NA item but if it selects item 1 from ZR it should never select item 1 from NA."), but I'm unable to reconcile the earlier description with the current one. Basically, it's not at all obvious to me what is supposed to be paired to what. Please clarify. Sorry for the confusing description. The code is only half-finished because I don't know how to continue, so it's definitely not clear from the code, you are right. I think I got a typo in there with #2 and #3. It should be: if ZR1 is selected, ZR1k must also always be selected (consecutively BZ1). What I'm trying to do is the following: Choose one item of either <item Zielreiz> or <Item Alternative>. If it chooses item 1 of Zielreiz (ZR1), it should then choose the according (numberwise) item of SuchbildZ, either version A (AZ1) or version B (BZ1), and the other, not chosen version (A or B), must be chosen at some point in the trial, too after ZR1k (which is just a copy of ZR1) was chosen. At the same time ZR1 should be eliminated as an option to choose from in <trial AltPresentation> and NA1 together with AN1 and BN1 should be eliminated as options in <trial Suche>. So it's always either ZR1 or NA1; ZR2 or NA2... Later, in <trial Wahl> there should always be one picture which was chosen in <trial Suche> next to one picture which was chosen in <trial AltPresentation> but never two pictures which were chosen in the same trial. And I need to know which picture was chosen for which trial, so this must be possible to see in the data. So, designwise following interrelations arise: - ZR1=ZR1k (I did the copies because the same picture in <trial altpresentation> has to be shown twice (with a fixation cross in the middle) and it seemed the easiest solution I was actually able to programm at that time). - ZR1=ZR1k are linked to AZ1 and BZ1. NA1=NA1k are linked to AN1 and BN1. NA2=NA2k are linked to AN2 and BN2, and so on. - If ZR1 is chosen in <trial Suche>, ZR1k must also be chosen in <trial Suche>. - ZR1 and NA1 are counterparts - if ZR1 is chosen in <trial Suche>, NA1 should be eliminated for <trial Suche> but be presented in <trial AltPresentation>. = Everything from <item Zielreiz> and <item Alternative> chosen for <trial Suche> should be eliminated as an option to choose from in <trial AltPresentation> - In <trial Wahl> there must always be one of <item Zielreiz> or <item Alternative> which was chosen in <trial Suche> next to one of <item Zielreiz> or <item Alternative> chosen in <trial AltPresentation>. - Only one of ZR1 or ZR1k should be chosen in <trial Wahl> (There's probably an easier way to show the same picture twice in <trial AltPresentation> where I can delete all the ZR_k copies I assume?) So what I basically need is a "if...then not.." and work with differents lists, right? I'm totally lost since I'm an absolute beginner :S The other option is always doing different groups where it is clear if ZR1 or NA1 is chosen in the <trial Wahl>, maybe that's just the better alternative here? I'm having trouble with the terminology here, because it's potentially ambiguous: "Choose one item of either <item Zielreiz> or <Item Alternative>. If it chooses item 1 of Zielreiz (ZR1), it should then choose the according (numberwise) item of SuchbildZ, either version A (AZ1) or version B (BZ1), and the other, not chosen version (A or B), must be chosen at some point in the trial, too after ZR1k (which is just a copy of ZR1) was chosen." What do you consider to be a "trial" in the above?
At some point in the <trial Suche>, so if ZR1 or ZR1k is chosen in <trial Suche>, the other one (ZR1 or ZR1k) must also be chosen in <trial Suche>

Do you mean the same instance of <trial Suche> or some other, later instance of <trial Suche>?

Wait -- how can there be 20 instances of <trial Suche> if you only have 20 items (ZR1 to ZR10 plus the copies ZR1k to ZR10k) AND the selection of items in <trial Suche> is supposed to eliminate items that can be displayed by <trial AltPresentation>? That would mean that there can be NO items left for <trial AltPresentation>.

There are 20 ZR items and 20 NA items to choose from. (That wasn't in our old design so it's not in the code yet).
As I said, I'm not sure the set-up of item lists as it is now is the best way to do it.

Well, no. It doesn't work that way. <trial Suche> can sample from one of those (let's say ZR), but you need a separate <trial> to sample from the other (NA).

Okay. I guess the best workaround then really are pseudorandomizations i.e. 6 groups where in each group it is clear which of the ZR items and which of the NA items are chosen for <trial Suche>.
Do I have to do that by creating 6 different <item ZR> lists --> 6 <trial Suche> -->6 different blocks for exp1 to exp6 or is there some better way?
And thank you for your help up until now already!!

I don't think you need to do that. If you set up two <trial> elements -- <trial sucheZR> and <trial sucheNA> -- you can prevent one selecting an item # that has already been selected by the other. Maybe let's start with this and perhaps you can build from there (since I'm still not entirely clear what you want the end result to be):
<values>
/ itemnumber = 1
</values>
// will run 5 sucheZR trials and 5 sucheNA trials
<block exampleblock>
/ trials = [1-10 = noreplace(sucheZR, sucheNA)]
</block>
<trial sucheZR>
/ ontrialbegin = [values.itemnumber = list.itemnumbers.nextindex;]
/ stimulusframes = [1=ZR]
/ validresponse = (57)
</trial>
<trial sucheNA>
/ ontrialbegin = [values.itemnumber = list.itemnumbers.nextindex;]
/ stimulusframes = [1=NA]
/ validresponse = (57)
</trial>
// 10 items in this example
// item # selected for ZR cannot be used for NA
// and vice versa
<list itemnumbers>
/ poolsize = 10
</list>
<text ZR>
/ items = ZRitems
/ select = values.itemnumber
</text>
<item ZRitems>
/1 = "ZR1.jpg"
/2 = "ZR2.jpg"
/3 = "ZR3.jpg"
/4 = "ZR4.jpg"
/5 = "ZR5.jpg"
/6 = "ZR6.jpg"
/7 = "ZR7.jpg"
/8 = "ZR8.jpg"
/9 = "ZR9.jpg"
/10 = "ZR10.jpg"
</item>
<text NA>
/ items = NAitems
/ select = values.itemnumber
</text>
<item NAitems>
/1 = "NA1.jpg"
/2 = "NA2.jpg"
/3 = "NA3.jpg"

Ok, thanks! The only thing is, that I need the copies of ZR and NA in order for them to be selected again --> for both AZ1 ans BZ1/ AN1 and BN1 to be presented. Is there a way to make that work? If not, I think I'm really just gonna go with the 6 groups and get it over with haha :)

I'm fairly sure there's a way to make that work, but I'm still not clear on that part, i.e. how you actually want this to behave.

I'm just gonna do the typing and set up 6 experiment groups, that's probably faster and definitely easier for both :)
Thank you so so much for your help and patience!
