JATOS changes format/appearance of the expertiment?

Silvia

Hello,

I am trying to use JATOS for the first time, so apologies in advance if I am making some basic mistakes.

I coded my simple experiment with jsPsych, and it worked well when imported in JATOS (locally). Then, I 'jatosified' my script by adding the relevants bits of code indicated here https://www.jatos.org/Adapt-Pre-written-Code-to-run-it-in-JATOS.html.

Now I do have some results saved, but the appearences of my task are changed. I used to have four images appearing in each of the four corners of the screen for each trial, and now the four images appear all aligned vertically. Please note that I did not change any part of the script concerning the style or the components.

Any suggestion?

Thanks!

Silvia

Hi Silvia,

That's odd. JATOS does not change the appearance of your task. I'll ask a few questions to try to understand what went wrong.

• You're still running your study locally, right?
• Do the figures align in the same way regardless of the size of your browser window?

I actually have no more questions, maybe you could send a minimal reproducible example of your code and I can have a look at it.

Best

Dear Elisa,

thanks for your quick reply!

While preparing the code to write this answer, I figured out the issue, which was very tiny and stupid. I will report it here just in case someone else in the future will have a similar problem and come across this thread.

The problem was that I had this line:

<script src="jatos.js"></script>'

instead of this line:

        <script src="jatos.js"></script>

So in other words, I only had an accidental apostrophe in my script. It did not raise any error or warning, but it messed up the whole format. Now that I fixed it everything seems to be working fine.

Thanks again!

Silvia
