Nested List Not Following Selection Rules

[Noam Schneck]

Hi All,

I have a task in which a slide object is used to present four words (Positive1, Positive2, Negative1, Negative2).  Each word is selected randomly from a list that contains 85 words in total.  This list "Wordlist" is nested into the master list.  I am trying to set the wordlist so that no words will repeat within a block (24 runs) but that they can repeat across blocks.  I set the parameters of the wordlist to random selection with replacement after reset.  I set the reset at 24 samples.  

HOWEVER....E-prime seems to have a different plan.  When I run a test on the task I find that the program goes through the first 3 blocks (72 samples) without ever repeating a single word and than in the fourth block it begins repeating words within the block.  I cannot figure out why this is happening and I have attached the experiment file. Please help!

Hi,Noam, I am trying to download the attachemnt you posted but it seems my version is lower than yours, so I cann't open yout profile to see the details. I suppose the four words cannot be the same and you may seperate the 85 words into 2 different groups: positive and negative. then randomly select 2 words from each group. I hope you can find a lower eprime version so I can see the details.

Hope everything goes well,

Sally

Hi Sally,

Thank you for the response.  Sorry for the e-prime version elitism.  I can't downgrade because I don't have the lower version and would need to reprogram the entire task if I did. I am attaching here an edat file extracted into an excel spreadsheet. If you look at columns DB-DK you will see the words that were selected for each trial.  Columns DD and DE  show the alternating blocks.  What this file shows is that for the first six blocks  there are no repetitions and then in blocks 7 and 8 (rows 153-200 on the excel spreadsheet) there are repetitions (highlighted in pink). The problem is that these repetitions occur within one block. I can't figure out why that is happening since I set the wordlist to random. I don't mind if the repetitions happen across blocks but I can't have them within blocks.

Let me know if you have any further thoughts,

noam

Dear Noam,

I have seen your excel profile and I have some questions about your procedure. How did you random the wordlist so that you can get the random 4 words to show? Did you write any inline codes or just random the list, if the latter, what's inside the list, how come the numbers named newlist1,newlist2,wordlist,wordlist2? This is why I would like to see your eprime program. I want the structure of your program so that I can get you.

Besides, I think you can group the 85 words into two groups, negative(list1) and positive(list2) and then make a master list list3,list1 and list2 are nested in list3, and in list3, you have 4 attributions:p1,p2,n1,n2, and you can define p1 as [list2:0],p2 as [list2:1],n1 as [list1:0],n2 as [list1:1], then you can set the weight of List3 as 24. I think this can work.you can have a try.

hope that helps.

My best,

Sally
