You beat me to it, I'll take a look at all of that. Thanks, Dave :)

Hi Dave,

Last question I hope!
The script works perfectly. The only thing I noticed is that the errormessage (text turns a different color) will also logically appear if the participant gives no response at all. Is there a way for me to make it so that if no response is given, the trial just moves forward to the next in the block without showing the errormessage?

Define a /responsemessage for "no response" that shows a blank stimulus:

<block alcohol>
/ trials = [1-10 = alcohol]
</block>

<picture alcohol>
/ items = ("1L_1.jpg","1L_2.jpg","1L_3.jpg","1L_4.jpg","1L_5.jpg","1L_6.jpg","1L_7.jpg","1L_8.jpg","1L_9.jpg","1L_10.jpg")
/ select = replacenorepeat
/ size = (80%, 80%)
</picture>

<trial alcohol>
/ stimulusframes = [1=alcohol, alc_categories1, alc_categories2]
/ validresponse = (32, 37)
/ iscorrectresponse = [(text.alc_categories2.hposition==20% && trial.alcohol.response==32) || (text.alc_categories2.hposition==80% && trial.alcohol.response==37)]
/ errormessage = (alc_categories1_clicked, 500)
/ correctmessage = (alc_categories2_clicked, 500)
/ responsemessage = (0, blankscreen, 500)
/ timeout = 5000
</trial>

<shape blankscreen>
/ shape = rectangle
/ color = white
/ size = (100%, 100%)
</shape>


<text alc_categories1>
/ items = ("Non-alcoholic beverage","Food","Non-food object")
/ select = replace
/ vposition = 50%
/ hposition = counter.type1pos.selectedvalue
/ txcolor = black
</text>

<text alc_categories2>
/ items = ("Alcoholic beverage")
/ vposition = 50%
/ hposition = counter.type2pos.selectedvalue
/ txcolor = black
</text>

<text alc_categories1_clicked>
/ items = ("Non-alcoholic beverage","Food","Non-food object")
/ select = text.alc_categories1.currentindex
/ vposition = 50%
/ hposition = text.alc_categories1.hposition
/ txcolor = red
</text>

<text alc_categories2_clicked>
/ items = ("Alcoholic beverage")
/ vposition = 50%
/ hposition = text.alc_categories2.hposition
/ txcolor = red
</text>

<counter type1pos>
/ items = (20%,80%)
/ select = noreplace
</counter>

<counter type2pos>
/ items = (20%,80%)
/ not = (type1pos)
/ select = noreplace
</counter>
