Problem with OSweb 'item form_text_display & item form_base is not supported'

AVDL

Hi there!

I'm trying to make a pilot study with OpenSesame and want to run the experiment online. The study is about perceptions of guilt and the procedure is rating the person of the photo on a 10 points likert-scale.

So, I spend hours understanding OpenSesame and finally wrote a script so that I have a 10 points Likert scale represented after the photo's etc.

But now I want to run my experiment online, but checking the experiment in OSWeb it says:

Compatibility check:

-Item form_text_display is not supported

-Item form_base is not supported

-Item form_text_display is not supported

So, what now? I've been searching for an answer in other discussions and I've read that the 'form_...' should be supported in the new version of OSweb allready? Is this true, can there be another explanation why my experiment doesn't works then?

OR: is there another way to run my experiment online (if OSweb does not support my experiment)?

OR: is there another way to replace the 'form_text_display&form_base' e.g. how do I create an instruction screen with an 'start' button and an Likert rating scale with an 'next' button, if these forms are not available?

Many many thanks in advance !

Hi Alexandra,

These items are not supported, so the compatibility check is correct.

OR: is there another way to run my experiment online (if OSweb does not support my experiment)?

No, the only way to run OpenSesame experiments online is through OSWeb (with its limitations).

OR: is there another way to replace the 'form_text_display&form_base' e.g. how do I create an instruction screen with an 'start' button and an Likert rating scale with an 'next' button, if these forms are not available?

You can recreate that functionality with a combination of sketchpad s and response items.

For the instructions, that's quite straightforward, because you can simply create a sketchpad with instructions, add something that looks like clickable button, and set the duration to 'mouseclick'.

For the rating scale, this is a bit less convenient, but the principle is the same. You can create a sketchpad with a rating scale, and then have this followed by a mouse_response item. This will collect the coordinates of the mouse clicks, which you can use later to determine what participants clicked on. Alternatively, you can use a touch_response item, which already recodes the clicks based on which cell of a grid participants clicked on.

The downside of this is that participants can click anywhere, and not just on the parts of the display that you would like to be clickable. One way to work around this is to encapsulate the rating scale in a loop that breaks only when a valid part of the screen has been clicked. I attached a simple experiment that illustrates this issue.
