Hi, Without knowing the details, your graph is a little hard to interpret, but here are few general remarks to clear things up: (Quote) When using the psycho backend, OpenSesame will simply use PsychoPy, so everything that applies to PsychoPy then…

Hi, The response_time is simply the time between the onset of the response item and the moment that a participant presses a key. Because of how you set things up, this means that you're measuring the response time relative to the moment that the so…

Hi Bruno, There is no difference: they are aliases. In OpenSesame 3.2, the API has been reworked to meet the PEP-8 style guidelines, which posit that class names should be capitalized. But backwards compatibility is of course preserved. Cheers, Se…

(Quote) That's right. The correct response refers to the mouse button, and not to the ROI. Good to hear that you got things working!

Hi, The way you've set up things, PlayWord will pause the experiment until the sound is finished, because duration is set to 'sound'. And only then Target_Response will start collecting responses, with the response time being relative to the start …

Hi Sophie, You can select a loop based on the subject_nr, using the module (%) operator, like so: (Image) So that part is pretty easy, and does not require any inline scripting. Then there's the question of how to divide each loop into 6 blocks…

Hi Dan, This can indeed be a bit annoying. There is no elegant way to suppress these messages, but you can disable the 'notifications' extension. This will disable all notifications though, including those that are potentially useful. Cheers! Seba…

Hi Paul, As a first step, I would walk through the tutorials to familiarize yourself with OpenSesame. Once you've done that you can try to implement the experiment yourself, and see how far you get. Of course you're always welcome to ask specific q…

Hi, If you get an error like that, you always get a 'stacktrace', which tells you exactly which line in your code the error comes from. So in the future make sure you include that in your question. In your case, I'm guessing this line is the culpri…

Closes as a duplicate of #3975.

First, can you confirm that you have enabled 'Delete temporary files that my apps aren't using' under 'Storage Sense' in the Windows settings? I suspect that this is the culprit (it's a relatively new feature of Windows). Second, could you try the …

@eduard I don't have any objections, but I share your doubts about whether it will be successful. @researchbyliv Perhaps you can elaborate a little on how this would work in practice?

(Quote) From the perspective of OpenSesame (and OSWEB), touch screens function like mouse input. So when a participant can do an experiment by clicking on things with a mouse, then he or she can also run the experiment on a device with a touch scree…

Hi Gabriel, There are two separate issues here. The first error that you get on Linux is indeed the same error as reported above, which has been fixed in recent versions of OpenSesame. So updating should resolve the issue. (I'm not sure which vers…
-
Hi Ana, In this experiment, you have disabled the option to log all variables, instead manually selecting a few variables, not including response_time. So that's why response_time is not in the log file. I would also take a good look at the way th…

Hi Benoît, Thanks for reporting and tracking this issue down. We're going to see what we can about it. Cheers! Sebastiaan

Hi Vincent, Is this also after OpenSesame has been running for a long time? And if so, how long approximately? And what version of Windows are you using? Cheers, Sebastiaan
-
Hi, It sounds like you can treat 'example' as a factor in your design, for example through a variable example_nr. See this tutorial for a similar situation: * http://osdoc.cogsci.nl/3.2//escop2017/#step-4-define-the-experimental-variables-in-the-b…
-
Why don't you try to implement my solution yourself first? :) Essentially, all you need to do is change the variable names in the script, and figure out how to insert the script into your experiment.
-
Hi, Just to avoid confusion, I suspect that you mean that you have one variable, let's call it my_var, which can have two possible values, 'a' and 'b'. Right? If so, you could count the number of occurrences of each value with a simple inline_scri…
-
Hi Mariela, Not really, but one solution that comes to mind is that you simply implement the rating scale using 5 separate image_button widgets, possibly with an extra image widget above them to make it look more like a proper rating scale. Would t…
-
Hi Vincent, To use form validation, you need to implement your form using Python code, as described here: * http://osdoc.cogsci.nl/3.2/manual/forms/custom/#creating-forms-using-python-inline-script It sounds like you've implemented your form with…

Hi Mariano, If you open the Questionnaire Template when you start OpenSesame then you can see how this is done! Cheers, Sebastiaan
-
Hi Ana, The avg_rt simply is the mean of the RTs collected so far since the last reset of the feedback variables. But I'm guessing you're not really asking about the formula for calculating a mean, but are confused about what happens in your experi…

Hi Bruno, That was indeed a bug, but it's resolved in 3.2.2, which should have landed in the Ubuntu PPA earlier today .:smile: Cheers, Sebastiaan
-
Hi, It sounds like you're running an older version of OpenSesame (2.9 or earlier), in which these advanced loop operations weren't implemented yet (and are therefore silently stripped). Is that it? If so, I would update to OpenSesame 3.2. Other th…

Hi Bruno, I suspect you have an older version of expyriment installed. What happens if you upgrade expyriment? You can do this for example by running: pip install expyriment --upgrade Cheers! Sebastiaan

Hi Solak, There are a few ways in which you could do this. The easiest way is to group the add the four checkboxes to a group (which you've already done), and then set click_accepts=yes. Then you can remove the button altogether, so participants h…

It seems that the temp folder, which is used by OpenSesame for the file pool, is cleaned up automatically after a while. However, my understanding is that Windows never does this automatically, which suggests that some other software is doing this. …
