Running experiment online

asifzach

Hi!

I have built an IAT test on Opensesame that I want to run online.

I saw it can be done with a JATOS server. How can I get access to one? (I tried to reach Mindprobe for an account but it didn't work)

Thank you in advance!

Hi!

If you have an ORCID iD, you can sign in directly into Mindprobe: https://jatos.mindprobe.eu/.

And from https://mindprobe.eu/:

If you do not have an ORCID iD, or if you do not want to use this for your MindProbe account, then you can request account. To do so, send a request by email to info@mindprobe.eu. In this email, provide a brief description (a few lines suffice) of your affiliation (independent researchers are also welcome) and the type of experiments that you want to conduct. We will grant all serious (i.e. non-spam, non-abusive) requests. Feel free to request multiple accounts at once, for example for multiple lab members.

Best,

Kristian

Hi! I did, and I got an account, but when I click on sign in it doesn't work...

Hi asifzach!

Sorry, but you have to be more specific. You got an account. Nice. What type of account do you have? A local one, an ORCID one? Do you get an error message?

With kind regards,

Kristian

I did the second thing you said, I sent an email requesting for an account and I did. But as I type my username and password, and click on the sign in button - nothing happens. Not an error message, nothing, just stays the same.

That is strange. I just had a look in Mindprobe and found a user that starts with 'asifzach', like your username here. Can I assume that is your user in Mindprobe? It says you never signed in so far.

When you open the developer tools of your browser and go to console, do you see any errors there?

Edit: I mean: when you open the dev tools while you are on Mindprobe sign-in page and try to sign in. Do you see any errors in the console?

asifzach

Yes, a few:

1. A preload for ... is found, but is not used because the request credentials mode does not match

2. TypeError: cannot read properties of null (reading '1')

3. The resource ... was preloaded using link preload but not used within a few seconds from the window's load event. ( shown twice)

kri

Can you please post a screenshot of the errors here?

Interesting. Apparently JATOS cannot parse your timezone. Can you please open the Dev Tools / Console and run the command:

new Date().toString().match(/\(([^\)]+)\)$/)[1]

and post the result here.

asifzach

still no...

Yes, this was only for me for confirmation that it is indeed the timezone that JATOS cannot deal with. I'll fix this. Sorry about the inconvenience. In the meantime you can set another timezone in Chrome like it is described here: https://stackoverflow.com/a/76694081/1278769. In Developer Tools under Sensors chose any location (just not your current one), what I tested so far they work all with JATOS.

Perfect! Thank you Kristian so so much. Do you maybe have an estimated time how long it will take to fix this?

Thank you!

kri

I'll fix this soon, but the time consuming part is to do a new release of JATOS and there I can not promise anything - a couple days maybe.

asifzach

ok I changed the timezone and I indeed had success logging in. But now when I click on the import study - it doesn't work...

kri

That is annoying. I can only assume that the file picker JATOS is using does not care for the set sensor location. I guess you have to wait for an fix of this bug in JATOS. Or, have you tried Firefox? Maybe the timezone handling is different there. Another idea: you can try a VPN to change the location, e.g. the Hola VPN.

Hi asifzach,

The latest release 3.9.3 from yesterday should fix your issue. It is already deployed to Mindprobe. I'd be happy if you can confirm.

Best,

Kristian
