Hi Emilia, Unfortunately, it is not very clear what you mean. Perhaps you can share your experiment and explain what your experiment is supposed to do and what it actually does? Generelly, once a variable is initialized it will keep its current va…

Hi Benoit, On a sketchpad, you add as many images and text fields as you want to present (12 each I think I remember). Then you need to specify for each what input should be used. It easier to first unpack the list into individual variables. I atta…

Hi app, No idea how this would work. Perhaps you can ask the tobii people about it? They just be able to point you towards the relevant sections in their python api that would allow with tobii studio. Good luck, Eduard

Hi Marie, Not sure I understand correctly, but the log file has always the same number of rows for all columns. So, if one variable is defined only one trial for some reason, it will still appear in all other rows (i.e. all other trials), either wi…

Hi Henk, Best practices with regard to what? In terms of performance or user experience? I don't think there are particularly strict rules. Design your form in any way that you find visually appealing. Performance-wise there shouldn't be many obstac…

Hi Dina, I am not an expert on that, but from what I can see in the source code implementing widgets and forms it is not that trivial to change. I think I could make it work, but only by changing the source code and without testing whether anything …

Hi Lola, I move your topic to the proper sub-forum. Then it is more likely that @Pascal will see it Good luck! Eduard

Hi fcosta, No idea what could have caused the issue, and I am not aware that this is a known issue, but if you post a detailed error message and some more information on the system, maybe some users that are familiar with Tobii can suggest somethin…

Hi Benoit, Well you still have the list with all items, right? In the inline_script inside the loop you select the current item out of the list based on the trial number. But the list with all items still says available. So you, can create a new sk…

Hi Alexis, Do you mean in the same data table as the gaze coordinates? It might be possible, but for that you better ask the Tobii people whether the eye tracking logs can be enhanced with behavioral variables. I know that this is possible for the …
-
Hi Emilia, Yes, that is possible. There is unfortunately not an online version of the IAT Tutorial, but as far as I can see there shouldn't be a problem, running that IAT as programmed in that tutorial for offline use. You can try it, in case it do…

Hi Sarah, If the change of the float variable and the generation of the canvas are both in the same loop, you don't need to do anything. Opensesame will use whichever value is currently stored in upper_safe_amount . if you generate the canvas onc…

Hi, I attach an experiment in which I give an example on how to implement the random metronome together with polling for keyboard responses in the same inline_script. I didn't quite understand your script with the remapping of the buttons and all t…

Hi Benoit, Attached a simple example experiment demonstrating the use of a "personal" accuracy variable. Let me know if it is unclear. Eduard https://forum.cogsci.nl/uploads/818/EKM9S31057MU.osexp ps. in case uploading to the forum here …
-
Both is possible. Why acc/accuracy don't work can have several reasons, you can share your experiment, and i can try to dig into what is the reason, but as you suggest, you can easily compute a new variable to calculate accuracy. Your formula is cor…
-
Hi, I suppose what already works is: assigning the words to the position presenting the correct image (and have a variable that codes the emotion of that image) Now define the correct response you can compare the emotion of the image to the word at…
-
Sorry, I don't get what exactly you mean. Do you want to know how to set the correct response? If so, what defines the correct response? Or do you want to know how to match the images to the words?
-
Hi B, So, my concern is that I would like the 4 words (happy, sad, surprised and angry) to be displayed differently in the 4 positions between subjects. You can apply a similar randomization approach to the words, but because the locations are fixe…
-
Hi Chris, This example demonstrates the principle. You can adapt it to your needs. Since i´m new to OpenSesame, please try explaining step-by-step. As I see, you are not only new to Opensesame but also to Python. Understanding both is quite useful…
-
Ah, I see what you mean. @sebastiaan, it seems impossible to flush keyboard responses before a text_input widget/form. I'd consider this a bug, or is there anything that I'm missing here? Eduard
-
Hi Smiddy, where did you do the keypress flush option? In a keyboard response item? If so, what was the duration of it then? I am surprised that this can happen. I would have expected that the text input form automatically flushes all the keypresse…
-
Hi, I attach an example experiment that demonstrates the principle of how the response collection would work. It is not particularly complicated. Let me know if something is not clear. https://forum.cogsci.nl/uploads/078/LO9A2WH6EIHF.osexp Eduard
-
Hi B, I am not entirely sure I understand your restrictions. You want for one subject to be the pairing of faces and biographies always constant? Or do you want to randomize in each block? The solution is almost the same either way, but requires so…
-
Hi AnneMarije, What is the best video format to use? Intuitively, I would say avi is the most robust video format, but that is not really based on any evidence, as I haven't worked with a lot of videos in my experiments so far. And are there any ot…
-
Hi Snap, in this case, you should set the duration of words_faux_2 to 0, and add a keyboard response afterwards, in which you set the allowed response to e . If you still want to log the response from the original (faulty) response, you need to s…
-
as far as I know this is not possible, and the last thing I remembered is that it probably won't happen soon. Right @Pascal?
-
Hi, Do you mean present response times and accuracy after every block, separately for congruent and incongruent trials? If so, you would need to do some scripting. If you use OsWeb the scripting has to happen in javascript, if regular Opensesame it…
-
Hi, Yes, most forms are implemented (see here) Additionally, it is now possible to directly build forms with html. See here Hope this helps, eduard
-
'time_problem' and 'time_final_RT.' However, there is barely any difference between them (285ms), which makes no sense. This is because every time the loop is executed (for every iteration), the variables defined in the loop are overwritten. Specifi…

Hi Soan, in one of the comments of the code example Fab has written: // !! This example does not include a logger; you'd have to add it to your task where appropriate which is the reason the variable does not appear in the data file. Right?
