That meme is actual footage of me developing OpenSesame.

There are a few things here: (Quote) To use the VLC plug-in, you need to install the vlc player to the default location, so that OpenSesame can find it. * http://www.videolan.org/vlc/index.html If you haven't done this, or if the plug-in fails to…

Hi Guido, If you pass the var keyword to widgets, like you're doing with the rating_scale, the response will be stored in an experimental variable. See also: * http://osdoc.cogsci.nl/forms/form-variables/ So you're doing it well, to paraphrase LL…

Hi Neon, Judging by the number of apologies in your first post, you probably realize that asking for last-minute advice one day before a deadline is not a great idea! That being said, @esdalmaijer has a description of how to install the Python bin…

(Quote) That is very cool to hear. And I look forward to visiting Granada next year for Psychonomics/ ESCoP! (Quote) This is purely a visual difference. The list that OpenSesame showed previously was slightly misleading, because there was no guaran…

You can just edit the first post and change the title to '[solved] ...' ;-)

Hi Guido, I don't know if this is what you ran into, but there's a bug in the joystick plugin in OpenSesame 3.0. This will be fixed in the next maintenance release (3.0.5), but for now you can just replace the joystick plug-in with the version from…

Hi Jacob, Normally, keyboard.get_key() returns only when a key is pressed. If you poll responses in a loop, as you're doing, a common strategy is to set the timeout value of the keyboard to 0, and to check whether a timeout occurred in the loop aro…

Hi, PyGaze doesn't support MyGaze—despite an uncanny name resemblance! I had actually never heard of MyGaze before. What exactly do you want to do? It sounds like you're mostly interested in extracting saccade and fixation events from eye-position…
-
Hi Jacob, This will indeed require a bit of Python coding, but nothing terribly complicated. Below you see an example of how you can adjust a 5-point scale with left/ right key presses, and accept by pressing space. The logic is explained in the co…

Hi, It seems like you're doing everything right, but also like you're confusing jitter and delay (or latency). * jitter is variability in playback onset. For example, if playback is sometimes delayed by 10 ms, and sometimes by 200 ms, then jitter …

Hi, Not really, no. You could take a look at the menu 'experiment' though. This is the code that implements the startup menu on OpenSesame for Android, and it's just a normal OpenSesame experiment. * https://github.com/smathot/OpenSesame/blob/mast…

Hi Alessandra, Based on your description, there is no reason why this would happen. Could you upload the full experiment so I can take a closer look? (For example to http://pastebin.com.) Cheers, Sebastiaan
-
Hi Pedro, This seems to be simply due to different versions of OpenSesame: 2.8.X for Windows (which is quite old) and 2.9.X on Mac OS. For the best crossplatform consistency, I would use the latest version that is available for both operating syst…

Hi Guido, I'm afraid not! Only a subset of HTML tags is supported, as described here: * http://osdoc.cogsci.nl/usage/text/#formatting-html-subset Cheers! Sebastiaan

Hi Florian, There are two questions here: The first is whether and how you can use the csv module on Android; the second is how you can execute a .py script from the file pool. First, the csv module is part of the Python standard library, so you s…
-
Hi, Your question is not specific enough! What exactly do you want to do? If you want to get a useful answer, you'll need to provide a detailed description of: * what you want to do; * what you have done so far; and * why this doesn't work as you …
-
Hi Michel, You're right, this import statement is missing in the joystick plugin. @joshua and I actually noticed this a few days ago as well. So that's definitely a bug. (Quote) I'm not sure what you mean by this, but it's not a good idea to impor…
-
(Quote) Exactly. So to avoid confusion: Would you agree that it's fair to say that you can characterize H1 (in this test) as follows? * H1 is not specified as an actual value, or range of values. (This, to me, would be an explicit prediction—realis…
-
Hi Tamara, That's a good question. My understanding (possibly incorrect or incomplete) is the following: * The null hypothesis (H0) is simply that the effect size is 0. * The alternative hypothesis (H1) is derived from the variance in the data. Sa…
-
Hi Flo, As an alternative, you can simply select an existing item in the 'Item to run' drop-down box of the loop. Does that clear things up? Cheers, Sebastiaan

Hi, This is a known issue with PsychoPy, which (I suspect) is related to memory corruption. There's not much you can do about it, I'm afraid. I haven't seen this problem with recent versions though; are you running the latest version of OpenSesame?…
-
Hi @alisdt and @harold_mb, I added a variation of this fix to PyGaze, which is newly packaged in the 3.0.3 prerelease. Would you mind trying out the latest prerelease (not 3.0.3a3) to see if this resolves the recalibration issue? * http://files.co…
-
Hi Chiara, (Quote) Yes, that's possible. I haven't really managed to replicate the issue. Transfer takes a bit longer than you might think is necessary, but nothing as excessive as what you're seeing. (Perhaps you need fairly big data files to see…
-
Hi Laurent, Unfortunately, you cannot access cameras from the OpenSesame Android runtime. So--aside from the non-trivial problem of using a webcam as an eye-tracker--this won't work! If you want to develop a mobile eye-tracking system, I would say …

Hi Han, Your design is not entirely clear to me. * Are you simply playing one long sound file during each article, or are you continuously playing individual sounds? * And how does the subject indicate that he/she has finished reading the article?…

Hi Tali, Thanks for pointing this out. Indeed, if you change the global font-size to a variable (through the script editor of the general-properties tab), an error occurs. That's the error you're talking about, right? (Issue #372) For now, what yo…
-
Hi Sonja, Indeed, the links are broken—and I cannot find them on my computer either. (Maybe @dschreij has them?) But, before we start digging in the archives, are you sure you need this version? 0.23 is almost 5 (!) years old, and incomparable to …

Exactly! This is one of the few intentional backward-incompatible changes in 3.0: * http://osdoc.cogsci.nl/python/sampler/#backwards-incompatible-changes-from-29-to-30

Hi Helene, First to confirm what Josh said: With 'dummy experiment' I indeed meant a simple experiment to see if you can get the connection with the SMI working—not a full-fledged experiment with PyGaze in dummy mode (which, in a sense, is the inve…
