Hi Noam, Thanks for pointing this out! It's certainly a bug, and I've filed an issue for it. For now I'm not sure what causes it. But as a workaround you can use a different backend, because the issue only affects the xpyriment backend. Cheers! Se…

Hi Luigi, The srbox plugin is installed by default, so you don't have to do anything. The icon looks like this: (Image) Cheers! Sebastiaan

Hi Juliane, This sounds very odd, and not something I've heard of before. I can view your discussions just fine though, also if I'm not logged in, so don't worry about that. But it's still odd. Just to clarify where things go wrong exactly, could …

Hi Sabrina, (Quote) Just to avoid confusion: form validation does not work with a form_base item. It requires Python scripting (i.e. an inline_script item), as also shown in the documentation. Are you sure you're not trying to paste Python code int…
-
(Quote) Yes, exactly. (Quote) I don't know without seeing your script :wink: Could you upload your experiment here?

Hi James, You can right click on one of the other toolbars. Then you will get a popup menu that will allow you to re-enable the items toolbar again. Hope this helps! Sebastiaan

Hi Sofie, The reason that pseudorandomization doesn't work here is that you apply loop operations afterwards, and these mess things up. The easiest solution would probably be to create a loop table that is already weighted (i.e. some rows occur mor…

Hi Celia, So just to avoid confusion, with 'path' you don't mean a file name, but a particular flow of the experiment. Right? You can do this quite easily by using a run-if statement to check the response variable that is set by the form_multiple_…

Hi James, That's a bug that has been fixed in 3.2.6, which will be released soon. For now, you can either disable the notifications extension, or download the latest prerelease of 3.2.6. * http://files.cogsci.nl/software/opensesame/pre-releases/ …

My guess is that: * The feedback items that follow the keyboard_response have the option 'Reset feedback variables' enabled. * These feedback items collect a key press of their own, which affects the response variables, such as correct. (But you ca…

(Quote) Yes, you can disable the 'Automatically log all variables' option and then explicitly indicate what you want to log, like so: var response [response]var condition [condition] (Quote) I'm not sure if stopping the recording will also prevent…

Hi Cecilia, Here's what you could do: * Have two keyboard_response items in a row, let's call them kb1 and kb2. * Then you can use run-if statements to determine which key was pressed first, e.g. [response_kb1] = a and [response_kb2] = space * Key…

Hi James, To force a white space, you can use (non-breaking space), which is the HTML representation of a space. Like so: x x x x Cheers! Sebastiaan

Hi Mathieu, (Quote) It probably has no practical effect. But as a matter of principle I can see why you'd like to be as precise as possible. (Quote) I have never used it myself, so I cannot give you detailed instructions. But yes, I imagine it's p…

Hi Rochelle, You posted only a fragment of the error message. Could you post the full traceback? You can find this in the debug window. Cheers! Sebastiaan

Hi Helio, If I understand correctly, the video plays back smoothly in dummy mode, but things become laggy if you enable the Tobii. Is that right? If so, that suggests that some part of the Tobii software slows things down. This could be either th…

Hi Maria, If you view the script of the sketchpad (by clicking on the middle button of the three buttons at the top-right of the sketchpad and selecting 'View script'), you will see that each element has a z-index. The z-index determines which elem…

Hi, (Quote) Without more information it's difficult to say what's wrong. Could you describe in more detail exactly what you want to do, what you've tried so far, and in what sense it doesn't work as you'd like it to? Attaching the experiment itself…
-
Hi Anda, This type of crash ("Python seems to have crashed") always reflects a bug somewhere in the underlying libraries of Python. It's never because of something that you did wrong in the experiment. (Quote) OpenSesame has its own Pyth…

(Quote) Absolutely!

Hi Liam, OpenSesame is not blazingly fast when starting up, especially on Mac OS. However, if it used to start faster, then something might indeed be wrong. As a first start you could take a look at the Plug-in and Extension Manager (under Menu → …

Hi Cecilia, I noticed that you posted a very similar question here. So I'm closing this discussion to keep the forum clean. In the future, please post each question only once! Cheers, Sebastiaan
-
Hi Cecilia, You can connect multiple keyboards to one computer, so that's no problem. Then, to be able to tell who pressed which key, I would have them press different keys (on different keyboards), rather than both press the spacebar. For example,…

@Evertox (Quote) I have thought about it, and it should be possible, at least to some extent. It would require writing a new backend that works with a VR device. And to make it actually useful, the drawing operations should support a z coordinate, …

(Quote) Good luck!

(Quote) Thanks for pointing this out. There was indeed a bug that could cause notifications to get stuck. It will be fixed in the next maintenance release!
-
(Quote) When a response time-out occurs, the response variable becomes None, as if the participant pressed a None key, so to say. You can check this with the following run-if statement: [response] = None. See also: * https://osdoc.cogsci.nl/3.2//t…

Hi Elena, You'll first have to tell us a bit more about how you've implement the visual-world paradigm! Perhaps you could attach the experiment to this conversation? Cheers, Sebastiaan

Hi Wieske, In the non-working example, the sketchpad items also contain show-if statements. This results in the odd situation where the show-if statements are evaluated during the Prepare phase of the trial_sequence, and then during the Run phase, …

(Quote) Reinstalling is unlikely to help, but upgrading is. The problem of course is figuring out which libraries to upgrade. Likely candidates are pygame and pyopengl (for legacy and xpyriment) and pyglet (for psychopy).
