Hi Tom, You're correct, OSWeb does not currently (v1.3.8) support sound recording. It may be possible to record sound through a custom inline JavaScript, but I have never done this myself, and I suspect that it will be challenging. But if you feel u…

@AliW 🤔 I don't see this, but it suggests that the enter key has a different name on your system, for some reason. (The experiment assumes it's either 'return' or 'enter'. That's hard-coded into the break-if statement of get_input_loop.) The experim…

Hi @chris8574 , Yes, a list of events can be found in the code of the example extension. This list contains all the events that are fired by the OpenSesame core libraries. Extensions can (and do, in some cases) fire their own custom events, which ar…

Your tip erased our first block we run the study on the internet. What do you mean exactly? What block, and in what sense was it erased by my suggestion?

Hi Chris, You are probably using the inprocess runner (under Menu → Tools → Preferences). Could you confirm that? If so, then I can reproduce the issue. For now, you can work around it by select the multiprocess runner instead. I think you misunders…

Hi @CSC , There's an issue with OSWeb that causes experiments to freeze when multiple linked copies of the same item are in a single sequence . In your case this is logger. You don't really need the second linked copy of logger though. Instead, you …
-
Hi Jelle, In what sense do you experience lag? I suspect that the interface freezes every second or so? Could you confirm (or disconfirm) that that's it? If this is the case, then I think that's because of the items that are being preloaded in the b…

Hi @brobinson , The 0-thing was a bug in previous versions of OSWeb. If you update OSWeb, or simply grab the latest release of OpenSesame, then this should be resolved! Cheers, Sebastiaan
-
Hi @Michif , This recipe from stackoverflow should allow you read text from a file through a URL. However, this file will probably need to be placed on the same server as the experiment, otherwise it will likely be blocked as a security measure. But…

Hi @Kian , Right now this is not possible, not unless you want to hack into the internals of OSWeb. However, it would make a lot of sense to make the welcome screen customizable, and so I've opened issue for that. Cheers! Sebastiaan

Hi Chris, This is a very strange error, and I don't see how it could arise normally. (The error appears to be that the experiment object doesn't have an items property, but it does.) Given that in another discussion you were asking about creating …
-
I also tried the commands you suggested and I get this error: You have to enable the inprocess console, as I explained in my previous post. Moreover, the problem I have and I want to figure out is, how to execute a specific event of an extension whi…

Hi Chris, Most likely an error occurs while loading the extension. To develop an extension, it's useful to enable a console with an inprocess kernel (Menu → Tools → Preferences), because this allows you to access the OpenSesame internals. (Normally,…

Hi @Sana_2 , Playing videos is not currently supported by OSWeb. You can find a list of supported functionality here: https://osdoc.cogsci.nl/3.3/manual/osweb/osweb/#supported-functionality But if your video is only 1 s long, then an alternative wou…
-
Hi @MikeN , I don't have experience with the pyxid library myself, but my understanding is that it is indeed only compatible with Python 2. So you would have to use the Python-2-based package of OpenSesame to use it. Alternatively (and again if my …
-
Hi @mariee , You can use the maxrep constraint by editing the script of the loop item and adding the following command (after all setcycle commands): constrain animal maxrep=1 See also: https://osdoc.cogsci.nl/3.3/manual/structure/loop/#pseudoran…
-
Hi Chris, You can fire events from within an extension like so: self.extension_manager.fire('some_event', argument1=value1, argument2=value2) This will then result in the following event-handler functions being called: def event_some_event(self, arg…
-
@Marie No need for scripting! You can adjust the repeat value in the controls of the loop item. https://forum.cogsci.nl/uploads/627/GD6MT0XW4DGP.png
-
Hi @Charles , The first thing to do is to assign names to the elements in the sketchpad . You can do this by selecting an element, and then entering something in the name field (which says 'auto' now). This is necessary for OpenSesame to know what t…
-
Hi @mariee , You can (temporarily) set the repeat value of the loop to a value less than 1. For example, if you set it to .02, then your loop will only run .02 × 200 = 4 cycles. Cheers! Sebastiaan

Hi @labovich , OpenSesame experiments do not run on Pavlovia, at least not currently. But you could also consider using this public JATOS server: https://experiments.jatos.org/jatos/login Cheers! Sebastiaan
-
Hi Charles, The variable cursor_roi contains a semicolon-separated list of the names of all the elements that the participant clicked on. (There can be multiple, because elements can overlap.) If you want to check whether the participant clicked on…
-
Hi @labovich , The list.reverse() function doesn't return the list in reverse order. Rather, it changes the list itself (inplace) such that the elements are reversed. But the return value of list.reverse() is always None . https://forum.cogsci.nl…

Hi @hulya , What exactly do you mean? How do you present the consent form, and how is the response collected? And do you want to be able to run the experiment online with OSWeb (which has some restrictions) or on the desktop? Cheers! Sebastiaan
-
Hi @hulya , I'm not sure where the delay comes from. If it's a reliably occurring issue, then it may be that something (I have no idea what) accumulates over time and eventually results in delays. @Daniel have you heard similar reports before? In ge…
-
Hi @nikitaadhikari1 , I think you can try to do this yourself 😀 To give you some idea of how to implement this. The event.code variable contains the key. If you define an allowed_response in your loop table, then you can check if event.code matc…
-
Hi @hulya , Having many loop items shouldn't by itself slow the program down. (Having many files in the file pool is a different matter, because the file pool is compressed during saving, and that can slow things down.) Are you using the latest ver…
-
Hi @jtdeakin , You can implement this with some creativity 😉 Generating random-dot stimuli in JavaScript won't be possible, but you can generate them offline with Python and then save them as images. Next, you store these images in the file pool, an…
-
Hi @nikitaadhikari1 , This is probably because you're not resetting the vars.first_key variable at the start of the trial, thus getting carry-over effects. If you add add the following lines at the end of the script, this problem should go away: va…
-
Hi @ainimj , I'm assuming that you have a series of sketchpad items in a sequence , and that they have names like word_w1, word_w6, etc. If so, then you can void word_w6 from being shown when the W6 variable is empty with the following run-if state…
