manipulating the selection of different items for text stimuli presented throughout a blocked experiment with noreplacenorepeat and resetinterval = 0

Hello,

I am currently working on a script where participants rate text stimuli on a Likert scale and am fairly unfamiliar with the language used in Inquisit and coding in general. In this experiment, there are 150 words that are presented across 10 experimental blocks (15 words per block). 75 of the 150 words are unique words which have been defined in the script as an item ("text2"); 25 other unique words will be presented 3x throughout the duration of the experiment and are written as 3 separate items containing the same content ("A11-A13"), making up the other 75/150 trials. The goal is to have the 25 repeated words presented each 1 time during the first 3 blocks (A11), another time during the next 4 blocks (A12), and then one final time during the final 3 blocks (A13). The other trials in each of these blocks should be randomly selected from the item containing the 75 unique words (text2), in such a way that words are not replaced, not repeated and the reset interval = 0 across blocks. The issue I am running into is that I cannot get two separate items to be used in each text (only "text2" words are used), and I cannot get the repetitions in presentation of the 25 words to match the experimental design I am aiming for when the are included. I did try to use a counter command to reset the interval at 0, but could not accurately write this command.

I have included the script below, which has been adapted from a previously used experiment:

<text word1>
/ numitems = 25 (item.A11)
/ numitems = 20 (item.text2)

This does not make sense in Inquisit syntax terms and won't work. A <text> element cannot have multiple item elements it pulls from, there may only be one.

What you need to do is have separate <trial> elements (or here: <likert>s, which are a special kind of <trial>) for the different word lists, and then sample from those trials as needed via your <block> elements' /trials attributes. You can use <list>s for trial selection if you need something more complex.

Let's take the 1st three blocks as an example. You have 45 trials total in these 3 blocks (15 per block), and you want 25 of those trials to come from A11, and 20 from text2 (the unique words). Then you do:

<defaults>
/ font = ("Garamond", -19, 700, 0, 18)
/ txcolor = (0, 0, 0)
/ validkeys = ("a" "5" " " "*" "m" "+")

You do the same thing for the other chunks of blocks.
