(Different, types of sentences, fillers included.)<br/>I was wondering whether there is a (simple) way how to program it in a way when two items of the same type don't&nbsp;<br/>appear next to reach other. I am using script downloaded from the library here, just slightly adjusted.&nbsp;<br/><br/>Since I am a complete beginner, I would really appreciate if you could provide examples from the script.<br/><br/>Thank you for your help.Mon, 07 Dec 2015 02:30:17 GMTmrtncgyhttps://forums.millisecond.com/Topic17912.aspxYou have five categories (1-5), with 16 items each.

It is working perfectly. <br/>Nevertheless, I tried to add more sentences (I have 5 groups of sentences and each group contains 16 sentences, together 80 sentences.)<br/>and I sucked there. I do realize that I do need to ch change something in the script you sent me but I can not figure out<br/>what it that.&nbsp;<br/><br/>Do you think you could help me with that?&nbsp;<br/><br/>Thank you very much.&nbsp;Sun, 06 Dec 2015 16:25:50 GMTmrtncgyhttps://forums.millisecond.com/Topic17874.aspxYou need to introduce a &lt;list&gt; that encodes your 5 categories, linked to the respective items. You enforce the "no two categories of the same type in a row" constraint via the &lt;list&gt;'s /maxrunsize attribute. For details see the attached script. It assumes 5 categories, with 2 items per category (10 items total). The main changes are in &lt;list mwstims&gt; and the use of list.mwstims.nextindex as opposed to list.mwstims.nextvalue in &lt;trial getstim&gt;.<br/>Wed, 02 Dec 2015 09:41:53 GMTDave
