http://forum.cogsci.nl/uploads/105/RYLM5BDWGA63.osexp Hi, The logic could look like in the attached experiment. Let me know if this is not what you had in mind. Good luck, Eduard Ort

Hi Chloe, I should be able to find the difference between the first mouse response and the trigger to get the time the participant started the task in the external software. But it doesn’t. How big is the deviation? Is it consistent? Can you prin…
-
Hi, Can you try to to press "Ctrl+\"? This should bring back the overview area if it is properly installed, but just hidden. But that is still a weird issue. Eduard

Hi Stephan, Sorry for the delay. I mean this file: https://github.com/smathot/OpenSesame/blob/koffka/openexp/_mouse/droid.py However, the (x,y) coordinates of the following clicks were not correct. This sounds to me, as if the screen is shifted sy…
-
You mentioned in the other script that this problem has been solved. Is that true? If not, did you check that the coordinates of the click and the stimuli match, even though they somewhat overlap? You can print out the respective variables in the d…

Hi Megan, The beginner's tutorial describes this scenario pretty well. You can find it here: https://osdoc.cogsci.nl/3.2/tutorials/beginner/ Basically, you randomize the side each response is presented, and then manually add a column to the loop ta…
-
Hi Shan, Sorry for this late reply. The problem is that both the Guess sketchpad as well as a the following keyboard item, require a response for the experiment to continue. What the user sees is that the experiment doesn't continue right away, but…
-
To add to Stephan's response, if you want to implement this with Opensesame, we can of course help you, but then you also should help us helping you. Specifically, what is the problem currently? Your steps so far seem to be reasonable. What works an…
-
Hi Stephan, Changing the color of the mouse is not possible easily (OS calls the system mouse), but you could try to have a mock click. I don't know exactly what is happening under the hood, but if you check the code for mouse.get_click(), you migh…

Can you share the experiment? Please, simplify as much as possible without removing the issue. Eduard

Sorry, I think I closed the window before the upload was complete... Here it is https://forum.cogsci.nl/uploads/118/QS62V7VJPR1A.osexp

Hi, Is this question different from the other one you have asked? Are you planning to play the 20 sounds simultaneously? In this case, you need multiple samplers, whose duration field has a value in it that is shorter than the actual sounds (other…
-
HI, Can you specify how exactly you are encountering the same issues? Can you give more details? Maybe share the experiment? Have you put the variable name in brackets (e.g. [sound_file]) in the sampler item to play the file? Eduard
-
One thing to do is to start recording eye data before taking the start time. Pygaze_start_recording takes about 300-400 ms to initialize. I don't think this causes delays but I usually start play the sounds before showing the image. Do these changes…
-
Have you put the code in the run phase of the inline_script? Can you share your experiment here? (Or, if it is very complex, a simplified version?)
-
What I suggest does exactly that. See the attached experiment for an example of the structure that you want. https://forum.cogsci.nl/uploads/686/NQKSZK3X2RIU.osexp
-
Maybe I am not understanding it right, but your sequence suggest that you have only a single block of 128 trials. while I propose having two blocks with 64 trials each. Isn't that what you want?
-
Hi Anne, How about, you only repeat the 18 trials 4 times, but wrap another Loop/Sequence structure around the trial loop and set its repeat value to 2? Does that make sense? Eduard
-
Hi Rex, This sounds like an interesting problem. I am afraid you'll need to use inline scripts in order to implement that. Attached an experiment that implements the basic procedure. I hope this gets you started. Eduard
-
Hi Timo, The response time variable is being created by the mouse_response or keyboard_response item (whichever you are using). So if you would add the the second canvas after that item, it should use the current response time. Alternatively (and m…
-
Sorry, but I fail to see why this makes the sketchpad solution better than the inline script. If lab members will not need to change anything, they won't do so either way. If they have change things, they also have to do so either way. In fact, I'd …
-
Were you referring to something similar or maybe I did not understand correctly? Yes, this is what I meant. yeah, this doesn't seem to be the case although I'm not 100% sure. Can you check, the response times? Are they all as large as the timeout o…
-
That's weird. Well anyway, here it is again: https://osdoc.cogsci.nl/3.2/manual/structure/loop/#pseudorandomization
-
Hi Jonathan, I have the hunch , the automatic ROI definition is not compatible with correct_response definition. So, in order to do provide feedback, you first need to do some computing. The attached experiment includes code to do that. Let me kno…
-
Hi Valentina, Identical response times would only make sense if the loudness was instantly exceeded or only after the timeout. I suppose this is not what happens? Anyway, the messages on the screen should not be the reason that you get weird effect…
-
Hi Jasper, This is not about whether Opensesame supports noise stim or not, but whether the version of Psychopy that is installed has this feature included. (When you import Psychopy and create a window like that, you bypass Opensesame's canvasses)…
-
Hi Kate, I can help, but can you please point me towards where exactly I can give you pointers? :) Eduard
-
Hi, In order to do this, you need to use inline (Python-based) coding. In particular, you can use pygame's (I believe psychopy also has this functionality, but I am not sure. Maybe check it), function that gets keypress and key releases. With this …
-
Hi, Yeah, Opensesame is only covering data collection, not data analysis. There are plenty software possibilities for data analysis. You can use JASP, python (pandas), R, Excel. I suggest you pick one of them and start a tutorial on how to analyze …
-
Hi Fabio, As far as I know, there is no "auto-segmentation" implemented in Opensesame. However, I believe with some Python coding, you should be able to segment words in a sentence and retrieve ROIs with a resonably low latency. Once you …
