MindProbe does not record 'form_response' and onset time of text_input form

choql

Hello everyone,

I am trying to run my study online using MindProbe, and it involves solving simple arithmetic problems in which the participants are asked to input their answer to a problem. I am using text_input form to present the questions, but when I run the study online, JATOS does not record the 'form_response' and the onset time of the text_input form. I need these two variables to calculate RT and accuracy.

Any input would be greatly appreciated!

Thank you.

This is a question for OSWeb, I'll move your question there

Hi @choql,

The issue you're describing would have to do with your program in OSWeb, not Mindprobe or JATOS in general.

To try pinpoint the origin of the issue, the first thing to ascertain is whether your task outputs these variables when you run it from OS, either through your browser or through an OS window. In the latter case , you just have to consult your data log. In the former case, you could use Javascript code to output to the console the form's onset time (note that if you want to measure RT, you can also output that variable directly; see https://forum.cogsci.nl/discussion/7616/does-text-input-form-have-correct-or-response-time-variable#latest).

My guess is that if the information you're after is not present in the data log when you run the study as a JATOS experiment in Mindprobe, it may well be because you did not include that variable in the logger's configuration. As you know, to run the experiment as a JATOS experiment, your experiment must pass the OSWeb compatibility check. This includes disabling the "Log all variables (recommended)" setting. This means that you have to manually indicate which variables must me logged. You can add variables by dragging them from the variables inspector (1), which will contain all variables for objects contained in your experiment, or insert them manually (2) by typing their name (to introduce variables that you created through code):

Could you check if the variables you need are contained in the list of variables logged?

If you're not sure, feel free to upload your task to the forum and I'll take a look.

Hope this helps,

Fabrice.
