The way to convert from degrees of visual angle to pixels and vice versa is described in detail here: * http://osdoc.cogsci.nl/miscellaneous/visual-angle/ If this information doesn't answer your question, could you be a bit more specific and descr…

@mariosav Do you have reason to think that many other people feel the same way? If so, an append button could be re-added.

Hi Lex, Thanks for this detailed explanation. It's a shame that the recent versions of OpenSesame don't work due to the segmentation fault. However I suspect that opensesamerun does not suffer from this problem, because it makes less (or no when st…

Hi, The best way to do this is to define your question as a variable (my_question) in a loop: (Image) Then you use only a single form_text_input, and use the variable my_question to indicate the specific question: Does that make sense? Making…

Closed as duplicate of #1390.

Hi, From what I understand, your approach is correct. Set rand_add to some initial value before the loop, and then increment it on every trial. But your question is a bit vague in what you want to do and how you have implemented this right now. Cou…

Hi @loics, Sure, you can use define a correct-response variable, and use run-if statements to do something only when a preceding response was incorrect. I would recommend following the beginner tutorial, which explains this in detail: * http://osd…

(Quote) Well, not really. Forms don't keep track of time, so there is no easy way to know when a user presses a button. What you could do is hack into the form's internals, and replace it's render() function, which is called each time that the form …

Hi, I'm not 100% sure, because @esdalmaijer implemented this, but my guess is that it doesn't matter whether you do the calibration in the experiment, or with TobiiStudio. It's just a matter of convenience. Assuming, of course, that the calibration…

Hi, It would be helpful if you post some more information about the structure of your experiment, including a screenshot of the overview area. But for now a quick guess: Did you put all your questions into one long sequence? A sequence is always ex…

Hi Andrea, I'm afraid the answer is the same: This will definitely need some coding! None of the plug-ins will do it. Cheers, Sebastiaan

Hi Simon, In principle you should be able to adapt the code from that discussion to detect voice offsets as well as onsets. But without seeing your modified code I obviously cannot tell what's wrong. However, wouldn't it be easier and safer to rec…

Hi Guido, You're not the only one, and you may want to take a look at this discussion: * http://www.cogsci.nl/forum/index.php?p=/discussion/1337 Cheers, Sebastiaan

Hi Dror, A segmentation fault is almost always due to PyQt4. So there's not much that you can do about it, except using a version different PyQt4. And this is not easy because PyQt4 it's generally part of the operating system. What Linux distribut…

Hi Neon, Thanks for pointing this out. It's a bug due to older code in the plug-in (#311). It will be fixed for the next maintenance release, but until that time you could easily fix it yourself by commenting the call to to_chr() on line 162 of th…

Hi @panos_uol, Great that you want to contribute! (Quote) Absolutely not. Adding a citable publication is just a way to get extra credit for yourself. What you could do is add the task right now without a publication, in which case it can just be …
-
Hi @panos_uol, To do this, you would need to build your own .apk package from the source code. This is actually not that difficult, but it will require some knowledge of Linux. Basically, what you would need to do is change the Android script such …
-
Hi Marie, If I understand correctly (but I'm not sure), the end of the c_him sequence is only reached when the participant has successfully completed the trial, so when you want to log everything. Couldn't you simply use a single logger and put it …

Hi Sophia, This problem has been reported before, but I'm not sure whether it has been resolved. Perhaps you could take a look at this discussion, and ask whether they made any progress on this? * http://forum.cogsci.nl/index.php?p=/discussion/798…

Hi, I've seen this too. It looks like a memory-corruption problem, and seems to be a bug in PsychoPy. It occurs only rarely and on specific systems, or perhaps under specific circumstances--I'm not sure. At any rate, I would see if you can find som…
-
Hi, You can simply think of touches as mouse clicks. So you can get the location, time, and duration (i.e. by looking also at mouse releases, which takes a bit of extra coding, but is possible). Multitouch and pressure sensitivity are not supporte…
-
Hi, Can you provide some more details? For example, what is taking up the disk space? Do you have a very large file pool? And what operating system are you using? Cheers, Sebastiaan
-
Hi Rino, That does sound like a problem then. I'm afraid there's little chance of a fix in the near future, unless this is fixed in the PyGame subset for Android. This is the library used by the OpenSesame runtime for Android, but unfortunately it'…

Hi Victor, To open a PDF, you have to double-click on it, or press enter. Is that simply it? If you click once, Qnotero will start a drag action so that you can easily copy a PDF to somewhere else. The creation of a temporary file is simply part of…

Hi, Thanks for pointing this out. The possibility of a virus is always a concern. However, I've never heard reports of this file being infected, the build environment is clean, and when I just uploaded the file again to virustotal it was classified…
-
Hi, Right now, your question is too vague. It's a loose description of your experiment, without any indication of what you have already tried or where you got stuck. So what I would do first is walk through a few tutorials. This will give you a ba…

Hi Frouke, I'm guessing you don't have the VLC python bindings installed. You can get these from here: * https://www.olivieraubert.net/vlc/python-ctypes/ There are multiple versions, but I think you need to pick the one that matches your version …

Hi Matt, I'm assuming you use the touch_response plug-in, is that correct? Although there's is no visible option to hide the cursor, you can hide it by adding the following line to the script of the touch_response item: set show_cursor no Does th…
-
Hi Dror, No problem. It looks like there is some older code in PsychoPy that triggers a warning. But for now it's harmless, and I assume the PsychoPy developers will fix this at some point. Cheers! Sebastiaan

Hi, Ok, you ran into a little bug (just filed it as #309). What causes the problem is that you have set the cycles variable of loop to a non-integer value: define loop loop set cycles "[blockCounter]" The GUI chokes on this, although…
