How to collect response time with "Form_Text_Input" on Mindprobe.

Joshua_Gabriel

Hello everyone,

So a little bit of background, my professor and I are currently planning to conduct a study where the participants are required to submit their answers in writing. The plan is to use Opensesame to record their answers along with the total length of time the participants need in order to finish each of their answers.

I have managed to code the command to collect the time using "inline_javascript" items (which is compatible with JATOS), which sandwich the "Form_text_input" item. It ran perfectly when I tested it on Opensesame, i.e. it recorded the total length of time of each "Form_text_input" items in milliseconds, which is perfect for my project.

However, when I tested in on Mindprobe, the time of each "Form_text_input" items are not recorded, even though there appeared to be no compatibility issues whatsoever and no error messages at all. Everything ran without any trouble, but the time was not recorded.

Now the questions are, what went wrong, and how to fix it and record the time on Mindprobe?

Thank you so much in advance for your attention.

Best Regards,

Joshua

Hi Joshua,

Does this happen on a local JATOS too or only with a remote one like Mindprobe. My hunch is that it has to do with OSWeb/OpenSesame and not so much with JATOS, @lvanderlinden what do you think?

Hi Kristian,

I haven't tried it yet on local JATOS. So far, I've only tried different configurations of my experiment on Mindprobe.

If the problem is with the OSWeb, will it be of any help if I send the javascript I use?

Here's the script:

• 1st Inline_javascript:

var start_time = Date.now();

• Form_Text_Input

• 2nd Inline_javascript

var exp = {};

var start_time = Date.now();

exp.response_time = Date.now() - start_time;

console.log("Response time: " + exp.response_time + "ms");

I've tried multiple variations and combinations of these codes. However, none seems to be successful in recording the data on Mindprobe.

If the problem is with the Osweb, I'll be sure to move this discussion to the appropriate channel.

Thank you for your help

Best Regards,

Hi Kristian,

I have tested my Opensesame program on my local server, and as it turns out, the program still doesn't work on the local server. Is this therefore a problem with the Opensesam/OSWeb and not with JATOS?

Thank you.

That is my first guess, yes.
