A main link to be directed to several different study links?

white_bird

Hi,

I am using OSWeb on JATOS.

I am conducting a psycholinguistic experiment.

For this experiment, I have created 8 sets. 

Each set was created as a separate study (osweb file). 

This is because any subject should see only one set.

My question is that I want to create a "main link" in JATOS so that when it is clicked by a participant, it should automatically direct him to one of those 8 study links. 

This direction (assingment) process can be random or sequential. The point is that at the end of the day I should have similar number of participations for these 8 studies.

My motivation for this "main link" issue is that I want to share it on a large e-mail list (e.g., consisting of hundreds of people) or on social media. So, when a person clicks the link, he should be directed to one of those eight links. This way, I can collect my data easily in a limitted time.

Is there a way to generate main links in JATOS?

Hi,

There are several options.

The most basic is probably to:

1. combine the scripts for all those different sets into a single study
2. Combine those with an additional component that sorts participants according to the condition that's least populated.

To do (1) please see this thread.

To do (2) see the Randomize task between workers in the example studies page.

If you get stuck in implementing this, ask here again.

However, it sounds like you have 8 different stimuli sets. I don't know OSWeb well but if there is a way to have a single script that depends on an if statement (or switch case) to determine which stimuli set to show, that might save you the bit of manual work in (1). You'll still need the batch-session-based randomization described in (2), but this might still be easier.

Hope this helps!
