Hi Patxi, Do you mean xy_circle ? At least xy_grid wouldn't produce a circle, but a regular grid. If I understand the source code correctly, for xy_circle, rho the unit should be pixels (standard unit in OpenSesame). Hope this helps, Eduard

Hi Jessica, When you say "Eyelink provides such a functionality" do you mean the pylink library? Or the old Eyelink plugins? It looks like Pygaze hasn't implemented that option. Still, if that option exits in pylink( which I think does), …

Hi Aisu, If I interpret this function here correctly, then it is indeed the left eye when using binocular recording. https://github.com/esdalmaijer/PyGaze/blob/f355d6aca2bf7be0cee4361ae8eb07ba0e97b9e8/pygaze/_eyetracker/libeyelink.py#L595 Hope th…

Hi Vivienne, On the link that Lotje shared, it says further up "You can add constraints for pseudorandomization to the script of the loop item. This shuffles the rows, even if Order is set to sequential. (Currently, this is not possible throug…

Hi Giovanny, Now, regarding my second question (i.e., how to capture the reaction time of every single click or how to do some mouse tracking) do you have any idea? I have read to how to do mouse tracking with canvas but no when using widgets and f…

Hi, I don't know what is the problem, but maybe one of the older discussions has tips that are useful to you? See here for example: https://forum.cogsci.nl/discussion/5335/open-sesame-with-smi-red-250 https://forum.cogsci.nl/discussion/3443/how-to-…

Hi, I move this discussion to the JASP subforum.

Hi Gio, have you tried to specify the dimension of the experiment on the experiment tab? Standard is 1024 x 768 which is rather small (fullscreen mode just fills the area around the here specified display dimensions with the background color instead…
-
Hi Elodie, Please provide more info on the experiment. What stimuli are you using? How many? What do participants need to do? Does it freeze (when it does) always around the same time? The same event on the screen? If you take one of the tasks enti…

Hi, be able to select any image from any other image? I am not sure I understand what you mean here. Generally, having arbitrary order and multiple selection is a bit tricky (I envision a display with many images that is scrollable, a bit like a we…

Hi Mengzhu, but it probably is unrealistic to ask all participants to use FireFox. Every modern browser has a fullscreen mode. This mode is commonly toggled with the F11 key. So you wouldn't have to ask your participants to use firefox, you just ne…

Hi, What do you mean with demo? I can't see a demo in the archive. Also which operating system are you running. I think it only works (if at all) on Windows. I still need more information to be able to help. As it sounds, the portable version doesn…

Hi, Could you provide more information on your problem? Could you provide a link to the instruction that you used? Do you use Pygaze standalone or as Opensesame plugin? What eye tracker do you have? Does the problem also occur when you use a dummy …

Hi Robert, For the randomization, it is easiest to do some Python programming. If your files are named in an intuitive way that is actually quite easy. For example. If you want a random sound (of the two) on every trial, and you have sounds that a…
-
Hi Arsal, If I am not mistaken, importing excel sheets as loop tables is supported in Osweb. So even if the advanced loop operations are not supported, you could generate the sequences outside of the Opensesame (with the software of your choice), a…
-
Hi Claudia, Additionally, I think your manipulation is conceptually quite similar to the beginner's tutorial. Only that instead of sounds, there images are counterbalanced across left/right. Have you had a look? Might generally be a good idea given…

HI hatim, I'm still blocked I don't know why I've tried to do the things said in the forum... What exactly do you mean with "I'm still blocked"? - when he types the last digit "0", we switch to another image imposing a rest time…

Hi, if you fill your loop in the run phase, you need to use a feedback item to present it, otherwise it will only show its state that it had before the run phase started. See this for more details: https://osdoc.cogsci.nl/3.3/manual/prepare-run/#sk…

Hi Sarah, The problem is this line: button, (x, y), time = my_mouse.get_click() In case of a timeout, the middle return value of get_click() is None and not an (x,y) pair of coordinates. As None cannot be split into two parts (x and y), the error a…
-
Hi, You are talking about the 2 items correct_feedback and incorrect_feedback , right? It seems that you never define the correct response variable, or am I missing something? You need to either have a vars.correct = ... definition somewhere, or…
-
Hi, Just put a sampler in between the loops with a very short duration. That way it is being played when a block ends and a next block starts. Apart from that, unless you have a good reason for not doing it, I would also add visual information tha…
-
Hi May, It is hard, because you don't have yet experience. I recommend doing a few tutorials. This is a great way to familiarize yourself with the software and get a better understanding of what you are trying to do for your own experiment. If you …
-
Mh, then I don't really know either. I would need access to an eye tracker to debug and find out what is going on. That you see that message is also a good sign actually. Are there any differences in how to log messages to the EDF between the two O…
-
Hi @mhilliard2 , Depends on what kind of feedback you want. If you want feedback directly after every response, it must be placed in the trial loop after the response item. If you want to present blocked feedback after a number of responses (e.g. a…

Hi @mhilliard2 Is this question still bug you, or has it been resolved by now, perhaps in this discussion? Eduard

Hi Pikachu, I've checked the variable inspector and yes, it's not there but I'm confused as to where it's pulling X from because basically, there are 2 volumes (X1 and X2), which are among the variables in the inspector. That part is indeed quite c…

Hi kolfers, I used this code: import sounddevice as sd from scipy.io.wavfile import write fs = 44100 # Sample rate seconds = 3 # Duration of recording myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=2) sd.wait() # Wait until re…

Hi Hannah, Would it be possible to extract the video from the experiment? So, essentially splitting the experiment into two parts? That long video is indeed a good candidate for memory issues. Eduard
-
Hi Sarah, Do you log the data while the recording it still on? I think logged variables won't appear after you have stopped the recording. Other than that the code looks fine. Back in the day (Opensesame 3.2), I used: exp.pygaze_eyetracker.log(&qu…

Hi Sophie, it sounds more like being an issue on the Tobii end. Their SDK should be able to retrieve and use the serial numbers of the tracker. Anyway, I don't think there is a real solution for it available in Opensesame or Pygaze at the moment. …
