Hi
I have a very basic query. My script doesn't loop through items. Below is a very simple Minimal Worked Example. It should loop through the sentences, but only displays 1. Thanks
Nick
<item sentences>
/ 1 = "A dog is a canine"
/ 2 = "A cat is a feline"
/ 3 = "A bear is ursine"
</item>
<item questions>
/ 1 = ""
/ 2 = "Did this sentence mention a cat?"
/ 3 = ""
</item>
<text sentence>
/ items = sentences
/ select = text.question.currentindex
</text>
<text question>
/ items = questions
</text>
<trial trial>
/ stimulusframes = [1-3 = noreplace(sentence)]
/ validresponse = ("Y", "N")
</trial>
<block block>
/ trials = [1 = trial]
</block>
<expt expt>
/ blocks = [1 = block]
</expt>

is not supposed to "loop" through sentences. A given stimulus object like <text sentence> will select one and only one item per trial, displaying the element repeatedly during the trial will not lead to a new selection. If you wish to display three different items during a trial, you need three different stimulus objects -- e.g. <text sentence_a> to <text sentence_c> -- and have your trial display all three.

Thanks. I'm afraid I don't understand. This is identical to one of the walk-through examples: the IAT script (snippets shown below). A series of items are defined and these are plugged into the text object. Then a trial object is created, in which the property 'items' references the text object. This successfully loops through the items. As far as I can see, my example has exactly the same structure as this, but it doesn't loop. There must be something wrong which causes it not to loop.

No,
<trial pleasant>
/ stimulusframes = [1=pleasant]
...
</trial>
is supposed to display the stimulus "pleasant" -- a single item will be shown per trial.
<trial trial>
/ stimulusframes = [1-3 = noreplace(sentence)]
...
</trial>
But you seem to expect the above to display "sentence" three times, each time showing a different item.
That is not the case, as I explained above.
If you were to run <trial trial> three times in a row, you would get three different items -- one per instance of the trial.

Okay. I see now. The series needs to be specified for the block object, not the trial object. The following code works...
<item sentences>
/ 1 = "A dog is a canine"
/ 2 = "A cat is a feline"
/ 3 = "A bear is ursine"
</item>
<item questions>
/ 1 = ""
/ 2 = "Did this sentence mention a cat?"
/ 3 = ""
</item>
<text sentence>
/ items = sentences
</text>
<text question>
/ items = questions
</text>
<trial trial>
/ stimulusframes = [1 = sentence]
/ validresponse = ("Y", "N")
</trial>
<block block>
/ trials = [1-3 = trial]
</block>
