Hi Jeremy,

That works perfectly. I will have the chance to provide two groups of participants with two different links and seqOrder=0 with if-else does the job. Thanks a lot for the help.

Hi Jeremy,

Regarding rshuffle’s, yes indeed, as you say all of them are rshuffle. I don’t know why I typed them here incorrectly. 🙂

The conditional with math.random has its problem, as you pointed, and this can result in problems for the experiment. So, I want to go with your first solution. I am not sure if I understood correctly: should I distribute the experiment with the first Sequence to the first 30 participants and then, change the Sequence in the script to the second one and distribute it to the remaining 30 participants like that? If so, I think this can be a problem because I want to make all participants start at the same time and I won’t be able to change the script.

But still, based on your proposal, I have come up with an idea, for which I have not been able to find the way to implement due to my poor JavaScript skills. How about if I have these two Sequences in my script inside an if-else statement (just as in your second suggestion) and also, keep track of the Counter. But this time, the condition will be the Counter and when it hits 30, the else condition (the second sequence) will start to be given to the participants. And of course, I will update counter at the beginning of the script. I tried it with xVar commands and also with plain var but could not get the variable properly. Is this doable or do you suggest any other way? Thanks a lot.

Best,

Hi Jeremy,

Thanks for the info. Yes, the order is randomized but not in the exact way I want. Actually, while searching, I came across this recent post of yours and this is exactly what I am looking for. It actually worked very well, but as you mentioned, only half of the items are shown. How can I overcome this problem?

Thanks again,

Hi Jeremy,

Thanks for your reply. I applied the way how it is grouped in the tutorial and it works fine. Now, participants from group A are able to see different conditions with different items.

My another question is also about how to randomize the conditions within a group. To be more clear, for example, in the tutorial, the participant from group A will see plural inflection of the first item, then singular inflection of the second item and so on, as stated in the table. What I want to do is if a participant sees the plural inflection of the first item, then it should be possible for them to see the plural inflection of the second item, not necessarily the singular. This should also apply to all items; they can see either plural or singular inflection of every item. After seeing all the items (let’s say 30 items in total), of course, the number of each inflection they see must be balanced (15 singular, 15 plural) but there should be variation in inflections each participant sees. How can I implement such a structure? Thanks for your help.
