Hi Daniel, The experiment is too complex for me to understand. But to answer this question: I have to find a way to exclude these events from the pygame event bus then. You can control that with the pygame.event.set_blocked(), pygame.event.get_block…

Hi Mollie, I think I understand now. The main trick would be to add a repetition target (target_1 in my example) after every regular target. This is done in the 'randomise variables' part of the script. Then, you need to also add a matching stimulus…

Hi Gérard, Thanks for reporting this. This is a bug in the OpenScienceFramework extension, related to special characters in the file paths. The bug seems easily fixed, but it would be helpful if you can test it for us. Could you replace this file: C…

Hi Helio, It goes without saying that all of us in this big community owe you immense gratitude for your incessant work in making OpenSesame always better. Thank you! That's great to hear, thank you! I don't know how much of crowd there is for this …

I think you uploaded the wrong experiment ;-)
-
Hi, The Canvas object that you're passing to drawTarget() is called cnvs, not canvas. (The name canvas does exist, but it's a function that serves as an alias of Canvas, and right now only exists for backwards compatibility.) Bottom line: If you cal…

Hi Rebmel, I suspect that the image file is simply missing (so that it's not a Mac OS specific issue). Perhaps the files are not included in the file pool, so that you have copy them along with the experiment from one system to another? In that case…
-
Hi Mirko, Having only one row strikes me as unusual data format. But assuming that's really want to do, then the trick would be to: Make sure that all variables that you want to log have a unique name so that they end up in different columns, and; R…
-
Hi Mollie, I think I roughly understand what you're trying to do, but the devil is in the details. Could you first explain exactly how you select the stimuli at the moment? What are the constraints? In what sense are you counterbalancing things (as …
-
Hi GoSugar, You'll have to be much more specific! ? In what sense doesn't loop2 work as you would like it to? Uploading the script, or describing how you've set up the experiment, would also be helpful. Cheers, Sebastiaan

> to account for the fact the trials are nested in subjects (and a random book effect per subject) Right, I was thinking about that too, but I was unsure how to indicate that. Thanks for all your help!
-
Hi MSB, Thanks for this. That makes sense. Our design is actually a little more complicated than what I described here, in the sense that there are four book categories, and four conditions. Does that make any difference for your proposed approach? …

Hi David, The Android runtime only supports the standard items that were included with the version of OpenSesame that the Android app was based on (3.1.8). So mousetrap will, unfortunately, not work, not even if you've managed to find an old device …
-
Hi Simona, In that case, another possibility that comes to mind is that the experiment uses an unconventional response device (maybe a joystick or mouse scrolling?) and that this sometimes results in so many response events that the event buffer ove…
-
Hi Olivia, Your question is far too open to get any useful help! 😉 I would recommend first familiarizing yourself with OpenSesame by walking though the beginner tutorial (if you haven't already), and then see how far you get. Then, if you get stuck,…
-
Hi MSB, Thanks for your reply. 😄 The gaze durations on A and B are somewhat dependent, but not perfectly. (If they were, we could indeed recode it without losing data.) Basically, there are three possibilities: People look at neither A nor B People …
-
Hi, The problem is that you have set the repeat value in the block_loop so low, that trial_sequence is never executed. As a result, the avg_rt variable is never set (because that's done by the keyboard_response). Cheers! Sebastiaan http://forum.cogs…

Hi Sophie, Merging those changes is probably more trouble than it's worth. So my pragmatic recommendation would be: Yes, tell the participants to use Chrome/ Firefox/ Safari. Cheers! Sebastiaan
-
Hi Özlem, Good to hear that you solved it! The last screenshot looks much better indeed. Cheers, Sebastiaan
-
Hi Sophie, This sounds like a compatibility issue, but an unexpected one because recent versions of Edge should work with OSWeb. We'll look into this, and thanks for reporting it! Cheers! Sebastiaan Ping @Daniel
-
Hi Özlem, > The number of displays is as I want them to be; but the problem is the test doesnt run as I listed them in the loop. It goes one happy one sad continuously. That sounds like the order of the sequence is set to 'sequential'. Would that…
-
Hi, OpenSesame currently does not support right alignment (only left and center), although this has been an open issue for a while. For now, a pragmatic (though not very elegant) workaround might be to create images of the text that you want to righ…
-
Hi Simona, The first thing that comes to mind is that some application running in the background might steal the focus on OpenSesame, and hence OpenSesame no longer receives keyboard events. If that's true, then switching away from the OpenSesame wi…
-
Hi Julia, There is, as far as I'm aware, no such fix. However, you could consider using OSWeb, and running the experiment through the Android browser? https://osdoc.cogsci.nl/3.2/manual/osweb/ Cheers! Sebastiaan
-
Hi JD, If you're using OSWeb to distribute your experiment, then all participants need is a browser and a link to the experiment. So they don't need to download or install anything. You can find more information here: https://osdoc.cogsci.nl/3.2/man…
-
Hi Mille, First things first, make sure that: You've upgraded to the latest version of OpenSesame (3.2.8) which comes with OSWeb 1.3.3 The experiment runs in a browser when doing a local test run (Alt+Ctrl+W) Once you've verified the above, you can …
-
Hi Lexa, What do you mean exactly with 'low quality'? If the pitch of the sound is incorrect (i.e. too high/ fast, or too low/ slow), you can fix that by setting the Sampling frequency so that it matches the frequency of your sound files. (Or conver…

I don't think there's anything that we can do about this for now. Or am I wrong, @Daniel ?
-
Hi Pablo, Thanks for pointing this out. And yes, we're aware of it! Cheers, Sebastiaan

Hi Chris, If you insert an inline_script into a coroutines item, the run phase of that script is executed on every cycle of the coroutines, so over-and-over-and-over again. To avoid this, you could for example set a marker variable in the prepare ph…
