Hi Javier, Here an example of complete randomization the way you describe it. If you have more restrictions it will become slightly more complicated, but this should get you started. https://forum.cogsci.nl/uploads/854/AEW4AOKJCJON.osexp Hope it h…

Hey, A few screenshots are not enough to diagnose the problem. Could you share your experiment, or explain in words (and sufficient detail), what you tried and at which stage things started to break? Eduard

Hi, is this your experiment? https://we.tl/t-Hn6WaE1Oqc (for some reason, I can't update here). It seemed that your osexp file was wrappend in another zip file.

Hi Stephanie, Can anyone help identify what the issue is? If you provide more info, we certainly can help, but at the moment that is not possible. For my experiment, I was wondering whether it's possible to include more variables? No problem at all…

Hi Gio, Yes, Fabrice is right. You're logic doesn't check out. I have read in several comments that it is enough just doing a subtraction between "t2" which is often the kb.get_key() and "t1" which is often "canvas_1.show(…

Great that it worked. Happy experimenting! Eduard

Ok, that is super weird. But good that you made it work!

Hi Megan, How exactly you retrieve subject numbers from Jatos, I am not sure. However, I suppose eventually you will have some unique value in the variable var.subject_nr With this variable, you can then make the counterbalancing. I attach an examp…

Not sure what happens at your side, but on my end, using None does the trick. See the attached script (I had to delete the sound bits, because It was not included in the filepool) https://forum.cogsci.nl/uploads/219/NOAIGGL5TKA5.osexp

In none of the mouse_response spaces, have i listed a 'correct_response', Do you see the gray message to the right of the fields? I think this should clear things up None should be fine, but just try whatever works (if not None, it must be a vali…
-
Hi, Well, the error message tells you. You specified the correct_response of the mouse response item to be Z . However, the last time I checked, my mouse didn't have a z button, but only a left, right, and middle button (and maybe some other fancy…

Hi Henk, Is there a way to reduce the size of the icons in the Overview of the experiment? Not that I know of. You might change it permantentely by editing the source code, but I also failed to find a telling setting when browsing through the code…
-
Hi, this could be because of the quotation marks, but I am not sure. In any case, you can add the correct_response to the loop table. Then you don't have the issue. See the attached example. As far as I can see, it works the way you intend it to. …

Hi Nash, If you share your experiment, we can demonstrate the change that we have in mind. Eduard
-
Hi Tom, Not sure whether it solves your issue, but you can save a lot of memory by just using a single image instead of one for every frame, and instead adjust the x position of the stimulus. See the attached example. Does that work for you? Eduar…

Hi Gio, have you seen this (old) discussion? Especially Sebastiaan's code? It might give you a good starting point how to deal with keyrelease responses. I would need to register the exact time when the space bar began to be pressed, when it was r…
-
Hi, What exactly is your problem? That adding triggers changes the response time? I don't know for sure. I am not very experienced with Co-routines, but your inline code looks that it might be a little heavy time-wise (establishing connections for …
-
Hi Paz, Are you sure this is possible? I am not a hardware expert, but I wouldn't be surprised if that is also challenging hardware-wise. A quick google also led to mixed results. In any case, if you think it works, it certainly will not work with …
-
Hi Mirko, Can you try to locate the folder that Sebastiaan pointed out? If you find it, you can replace the file in it with another file that contains a checkbox of your liking. Should be a simple image file. On my system (Ubuntu) the files are lo…
-
Hi Mirko, That is a question you should ask the Shimmer3 guys. If they provide a Python api, you are right in that you probably can access the device and start/stop the recording via an inline_script. However, as it seems here they don't seem to ha…

Hi Chiara, Disclaimer: I'm in now way experienced with VR experiments. As far as I know, VR experiments are usually implemented in Unity, which is based on C#. If I read this Package correctly, you can access Unity from within Python. Therefore it…
-
Great!
-
Generally, you can use following procedure. Identify the missing package based on the error message (Usually the part "ModuleNotFoundError: No module named <MODULENAME>" gives it away Look online how this package is installed (that …
-
Ah I see, if you need audio (just) using opencv won't work. It might be worthwhile to invest time into the dual setup. As for the plugin, I can't give you reliable information. Back in the day when I still used it occasionally, I usually ended up t…
-
Yes, @Fabrice is right. In most cases the run phase is the place. Only exception is when you present the stimulus programmatically during the prepare phase. Then it would make sense to also send the triggers in the prepare phase. (General idea, is t…

Hi Leonardo, I moved this discussion to JASP. There you will get an answer quicker. Eduard
-
If you have an account, you can watch the repository, and then you will get notifications if there are updates. If you feel adventurous, you can of course try to find out what is the problem, or even fix it yourself. There are also some workaround …
-
Hi Anna, sorry for the late reply! But I guess it will be much easier if it's possible to overlay the webcam frame over the whole picture with the visual stimuli. I agree. I am not 100% sure but the frame variable in your script is essentially not …
-
Hi, I am not a video export, particularly not regarding the plugins, so 90% of my advice when it comes to video playback is to use OpenCV2. As it is scripting based (and not particularly difficult), you can integrate it quite easily with custom cod…

Hi Suleyman, You mean dragging and dropping stimuli? That is possible, but requires rather intense Python-coding. Most likely easiest done in Pygame. So you can load the packages, and then try to implement what you need based on existing code, such…
