Hi Candice, Regarding your first question: How exactly should the procedure look like, if there are multiple correct responses? That is, does the participant only give one answer and this is classified as correct if he / she clicked on say option 2…

Re Question 3: If you would like to use images as buttons on a form, you can use an image_button widget. You can add this using OpenSesame script to a mousetrap_form item. However, if you are not interested in the mouse-tracking data, you could al…

Re Question 2: If you would like to have more than 4 buttons and want to use a sketchpad / canvas for presenting them, you cannot add them to a mousetrap_response item by modifying its OpenSesame script. Instead, you would use the MT_response class…

Thanks, @sebastiaan, just was looking at it :smile: Re Question 1: The coordinates x=-288 y=192 w=-224 h=256 represent a button with the coordinates (-288, 192), (-288, 192+256), (-288-224, 192), (-288-224,192+256), i.e., (-288, 192), (-288, 448)…

Hi, if you want to use a sketchpad to create the visual display (i.e. to draw the boxes), you could use the mousetrap_response plugin to track mouse movements and clicks, and to define regions on the sketchpad that represent buttons. The mousetrap_…

Hi Emma, regarding your second point: If you want to define clickable regions on a sketchpad, you could use the mousetrap_response plugin for OpenSesame: https://github.com/pascalkieslich/mousetrap-os However, one caveat regarding your specific de…

Just tried it out, also happened for me sometimes when pressing the keys exactly at the same moment. I rewrote the code a bit (see below), cleaning the indents, using two different keyboard objects and flushing them after data collection (just to b…

Dear Clément, glad that it worked! Regarding the adaptive feedback: The procedure you proposed sounds good to me and you could indeed extend the code I proposed above, e.g., in this direction: if var.response=="OptionA": var.response…

Hi CL, sounds like a cool experiment! I think I know the source of the problem: when you specify the name of the button that is logged, I assume that you are using the value that is displayed for that button (which is what we usually recommend to …

Hi, one plug-in that might be useful for your purpose is the mousetrap_response plug-in (https://github.com/pascalkieslich/mousetrap-os). Basically, it allows you to define rectangular regions on the screen (in the same way a rectangle is defined o…

Hi Amihai, I am not completely sure what your exact problem is. Are you using a button in a form base plugin and do you want to know the total response time for the form? If so, I don't think that it calculates response times. However, you could …
-
Just to point out another, completely different approach: you could use a standard form_base item (http://osdoc.cogsci.nl/forms/custom-forms/) with images corresponding to the different colored options. Beneath each image you could place a checkbox …
-
Ah, ok, that makes sense. In this case you cannot directly use the plugin. It continously registers clicks but ends tracking once a click was on a button (similar to the buttons in a form). However, there are several work-arounds: 1) You could nes…
-
Just to clarify: the task of the participants is to click on several buttons in the trial (and all clicks need to be collected)? How do participants indicate that they are finished?
-
Hi, I am not sure whether it helps but: in case you want to use a sketchpad/canvas to draw your different response options, you could use the mousetrap_response plug-in to define buttons and collect the respones afterwards. We developed this plug…

One additional note regarding the experiment under discussion: I don't know the specifics of the experiment, but I assume that our ultimatum game example (https://github.com/psynteract/psynteract-os/blob/master/examples/ultimatum_game.osexp) could b…

Hi all, I just wanted to point out the psynteract plug-ins that a colleague of mine, Felix Henninger, and I are working on at the moment. They are designed to implement real-time interactive experiments in OpenSesame using simple drag&drop item…

Hi EJ, thanks a lot for your helpful answer! I will have a look at the papers you pointed me to. In the project I am currently working on, I am also reporting reporting JZS Bayes factors for t-tests. So I will probably report the Bayes factors fro…

Hi all, I am experiencing the same issue (I am using the latest version of OpenSesame: 2.9.5). Basically, what happens is the following: I copy the example form from the homepage (http://osdoc.cogsci.nl/forms/custom-forms/#creating-forms-using-op…

I am working at the University of Mannheim, Germany. We have included a module on research techniques in our Master's programme. And as one of the options, I am giving a 4 day workshop on programming experiments in OpenSesame (with a short Python in…

Hi Sebastiaan, thanks for taking care of the issue so quickly. It is currently not a problem for me as it only concerned an exemplary task in a workshop I am giving on OpenSesame. Best regards, Pascal

Hi everyone, I just wanted to briefly mention that I was unable to find the GUI field "Response variable" for the form_multiple_choice. I still can specify the variable using form_var in the OpenSesame script - however, I don't have a fie…

Hi Sebaastian, thank you for your ideas! Switching the back-end to legacy did solve the problem, disabling OpenGL, however, did not work. Thanks also for pointing out the PyGame issues: the command self.mouse.set_visible() seems to cause the cen…
