Hi Charlotte, > I was just wondering what is the most recent version of Android that OpenSesame is known to work on? This new tablet is running 8.1.0 and I'm hoping there's some way to downgrade it to an earlier version, but I just would like to …

> Is it true that using clicks in ROIs cannot be used as correct response in a mouse response item? Yes, that's correct. The correct response refers to which button is clicked, and not the ROI. (That's not ideal, because you're usually more inter…

Hi, Thanks for pointing this out. I had indeed forgotten to copy `python-pseudorandom` and `python-fileinspector` to the 19.10 (Disco) series. I just did this, so the packages should be available soon! Cheers, Sebastiaan PS. Synaptic, `apt`, and `ap…

Hi Lina, That's an interesting scenario. So I guess you want have a checkbox that participants can check to indicate that they don't want to check anything on the rating scale. Right? Of course the most pragmatic solution would be to simply add one …

> In other words, it seems like the options for changing the coordinates system applies only to inlines... That's correct. The option only affects the behavior of inline_script items. The sketchpad has always used 0, 0 for the display center.

Hi Cayley, The first message, about ffmpeg, reflects that OpenSesame fails to download the software that is necessary for running video files. That's probably harmless in your case. The second message, about not being able to read the .xlsx file, pr…

Hi Atefeh, > I appreciate it if you could check the test and inform me whether I can use the script of this test and copy in OpenSesame and run with it. If you literally mean whether it is possible to copy the script from the Inquisit Lab to Open…

Hi, The easiest way to do this is to use the xy_random() function to get a random set of coordinates, and then add the target and distractors as Image elements to a Canvas with a script like the one below. This assumes that, in the file pool, you ha…

Hi Andrew, openpyxl is the library that is used for reading .xlsx files. But it should be installed by default. What happens if you run the following command in the debug window? import openpyxl Do you get an ImportError? If so, you can install the …

Hi Emilie, I'm afraid that the OpenSesame runtime for Android is no longer developed, and therefore I wouldn't recommend using it. (Unless you happen to have an old smartphone or tablet that is still compatible with it.) Another option might be to b…

Hi Gérard, The checkboxes are hardcoded into the form theme. Therefore, to change them, you need to override the function that draws them. The script below takes two images from the file pool (box-checked-large.png and box-unchecked-large.png) and u…

Hi Martin, You can implement this using a form validator (only available when creating forms in an inline_script). The validator is a function that returns True or False depending on whether the form should be accepted or not. You can also use this …

Hi, The maxrep constraint refers to direct repetitions. So constrain digit maxrep=1 means that digit will not have the same value on two consecutive trials, but the same value may repeat at longer intervals. In your case, it seems that you want to r…

Hi Peter, This is very strange behavior indeed, and I don't know where it comes from. Thanks for putting this on the radar though. If we manage to replicate it, or hear more of these reports, we'll get on top of it. For now, at least you have a work…
-
Hi Tali, In old versions of OpenSesame, sketchpads and Canvas objects used different coordinate systems, where 0, 0 referred to the center or the top-left respectively. So that's the behavior that you get when you disable the option uniform coordina…

Thanks for sharing!

Hi Peter, Before considering the option that OpenSesame really doesn't write to the log file (which strikes me as unlikely, although nothing is impossible), let's exclude some more trivial options. You say that there's an empty log file. To make sur…
-
Hi Peter, The most obvious reason for completely blank log-files is that there is no logger in the experiment (or that it is never executed). But if that's not it, could you attach the experiment to this discussion so that I can take a look? Cheers!…
-
Hi Hadas, That's an interesting scenario. The trick will be to use a loop for each random sequence type, let's call it loop_type_1 (for type 1, etc.), which has 8 cycles, such that each cycle corresponds to one random sequence type. In the loop tabl…
-
Hi Laura, The easiest way to implement this is probably by drawing all the stimuli onto a sketchpad, and then giving the rectangle elements that you use for the response boxes a name. Then you can have the sketchpad followed by a mouse_response, and…

@eduard @DahmSF Thanks, that's easy to add and might be useful to some people.

> @sebastiaan do you have plans to create a separate doi/manuscript for the osweb version? No concrete plans, but it would make sense to at some point write a paper about OSWeb with some benchmarks etc. But for now I would indeed recommend citing…
-
Hi Paula, You're probably using the xpyriment backend, right? In some cases, there seems to be an issue with the upper line of pixels of a line of text being moved to the bottom line. A kind of wrap-around issue, if you see what I mean. As a workaro…

Hi Michael, Thanks for reporting this. I haven't seen this before, but I'll see if I can replicate it, and in any case it's on the radar now. Cheers! Sebastiaan

> I would say that a change less than an order of magnitude is not substantial for a BF that is a ratio, after all From a statistical perspective, that's probably true. But imagine that you're reading a paper that reports a BF of 2, and compare t…

Hi, You can use either Python 2 or 3, and the version of PyGame would then be the version that's bundled with OpenSesame, which you can check by inspecting the pygame.__version__ property in the debug window. If you're trying to run PyGame scripts i…

Hi Jiatian, For me, the plugins still work with OpenSesame 3.2.8 on Windows, so I suspect that you haven't placed the folders correctly. Here's how the folder structure should look like: http://forum.cogsci.nl/uploads/632/S3M0Q61LBYTK.png In general…

Hi, If you're using regular response items, such as the keyboard_response, then you need to set the correct_response variable in order for OpenSesame to keep track of accuracy and average response times. This is described for example here: https://o…
