Why does your counter have 50 items / return item numbers from 1 to 50

<counter emotional>
/ items = emotional(1-50)
/ select = noreplace
</counter>

yet there are only 5 words (i.e. item numbers from 1 to 5)?

<item emotional>
/1 ="        ABUSE        "
/2 ="        AGONY        "
/3 ="        AMPUTATE         "
/4 ="       ASSASSIN        "
/5 ="        BLEEDING        "
</item>

I don't quite understand how that's supposed to work.

Generally speaking, though, your overall approach is correct. If you had 50 items, you would set up a <list> or <counter> with item numbers 1 to 50, and then have the three <text> elements sample item numbers from that same, single pool:


<block allemostroop>
/preinstructions=(allemostroop)
/trials=[1=ready; 2-51=noreplace(emo_green, emo_blue, emo_red)]
/errormessage=(errormessage, 0)
</block>

<trial emo_red>
/stimulustimes = [0=emo_red]
/posttrialpause = 250
/validresponse = ("red", "green", "blue")
/correctresponse = ("red")
/timeout = 3000
</trial>

<trial emo_blue>
/stimulustimes = [0=emo_blue]
/posttrialpause = 250
/validresponse = ("green", "blue", "red")
/correctresponse = ("blue")
/timeout = 3000
</trial>

<trial emo_green>
/stimulustimes = [0=emo_green]
/posttrialpause = 250
/validresponse = ("green", "blue", "red")
/correctresponse = ("green")
/timeout = 3000
</trial>

<text emo_red>
/items=emotional
/color = (255,0,0)
/select = list.emoitemnumbers.nextindex
</text>

<text emo_blue>
/items=emotional
/color = (0,0,255)
/select = list.emoitemnumbers.nextindex
</text>

<text emo_green>
/items=emotional
/color = (0,255,0)
/select = list.emoitemnumbers.nextindex
</text>

<item emotional>
/1 ="        ITEM 01        "

/31 ="        ITEM 31        "
/32 ="        ITEM 32        "
/33 ="        ITEM 33        "
/34 ="        ITEM 34        "
/35 ="        ITEM 35        "
/36 ="        ITEM 36        "
/37 ="        ITEM 37        "
/38 ="        ITEM 38        "
/39 ="        ITEM 39        "
/40 ="        ITEM 40        "
/41 ="        ITEM 41        "
/42 ="        ITEM 42        "
/43 ="        ITEM 43        "
/44 ="        ITEM 44        "
/45 ="        ITEM 45        "
/46 ="        ITEM 46        "
/47 ="        ITEM 47        "
/48 ="        ITEM 48        "
/49 ="        ITEM 49        "
/50 ="        ITEM 50        "
</item>

<list emoitemnumbers>
/ poolsize = 50
</list>

If, say, item number 23 gets randomly selected by <text emo_red>, the two other <text> elements cannot sample item number 23 anymore.

HI Dave,

Sorry for the confusion, in my script I do have 50 items, but did not want to list all 50 in the post... Thank you for your help!

Ah, thanks for the clarification. Have you tried changing the code along the lines outlined in my previous reply? If so, are you still seeing any words repeat where they shouldn't? Thanks.

Hi Dave,

I recently revisited the script, and saw that it still repeats words from the list (though only twice and not nearly as often as it used to). Do you have any suggestions on how to proceed?

Best,
JIn

Well, I don't have your script, but only the few excerpts you posted in this thread. So I cannot tell you what may be wrong with it. What I can tell you is that I am not seeing any repetitions using the example code I posted here earlier, specifically:

<block allemostroop>
/preinstructions=(allemostroop)
/trials=[1=ready; 2-51=noreplace(emo_green, emo_blue, emo_red)]
/errormessage=(errormessage, 0)
</block>

<trial emo_red>
/stimulustimes = [0=emo_red]
/posttrialpause = 250
/validresponse = ("red", "green", "blue")
/correctresponse = ("red")
/timeout = 3000
</trial>

<trial emo_blue>
/stimulustimes = [0=emo_blue]
/posttrialpause = 250
/validresponse = ("green", "blue", "red")
/correctresponse = ("blue")
/timeout = 3000
</trial>

<trial emo_green>
/stimulustimes = [0=emo_green]
/posttrialpause = 250
/validresponse = ("green", "blue", "red")
/correctresponse = ("green")
/timeout = 3000
</trial>

<text emo_red>

/select = list.emoitemnumbers.nextindex
</text>

<text emo_blue>

/49 ="        ITEM 49        "
/50 ="        ITEM 50        "
</item>

<list emoitemnumbers>
/ poolsize = 50
</list>

When you run the above code -- and only the above code -- do you see any repetitions?

I only added the emotional trials as not not make this post super big, but I do have a practice trial and neutral trial in the experiment as well - both follow the same logic.

Sorry, the partial code is _not_useful. What the mere excerpt does _not_ answer is whether you are using the <list> anywhere _other_ than during <block allemostroop>, for example in the practice <block> which you did not include. If you do so, that explains later repetitions -- you would have to reset the <list> at the start of <block allemostroop>.

Note that you do _not_ need to paste the script into a post here. You can simply attach the actual *.iqx file by clicking +Insert -> Add File.

Here's some runnable code derived from your excerpts -- I merely stripped out the missing blocks, etc. you did not include.

I am not seeing any repetitions, as you can determine from the attached data file. Run the code exactly as posted, please, nothing else. Are you getting any repetitions?
