Hi SINE, If you have the record and stop items in the trial loop, that is normal indeed. These two items need some extra time to communicate with the eye tracker. To prevent that delay, you need to move them outside the items between which you need…
-
Well, the canvas needs the full path for showing the image. So, you essentially can't use the same variable for logging and for presenting. Log them separately, e.g. var.stimulus1 = 'bird.png' while var.stim1_file = <full_path> You could also …

Hi Lauren, you can check out the co-routines: https://osdoc.cogsci.nl/4.0/manual/structure/coroutines/ The example with the stop-signal is also applicable to your paradigm, only that you need to turn around cue and probe (cue starting at 0 and prob…

Hi Katerina, you can leave out the pool/ part and simply write {chosen_image} see the beginner's tutorial. There, this exact use case is explained. https://osdoc.cogsci.nl/4.0/tutorials/beginner/#step-6-draw-the-sketchpad-items Eduard

Hi Sarina, Unfortunately, forms don't allow the measurement of response times that happen within the form itself. You only get the time of when the form was called and the time of when the item after the form was called (these are the numbers that …

Hi Leonardo, Like with correct, accuracy is probably not computed automatically if you don't have a keyboard or a mouse item. So, you need to implement it yourself. The ingredients are: Before the loop initialize three variables: total_trials , a…

Hi @blancasanmi , Have you seen this functionality: https://osdoc.cogsci.nl/4.0/manual/python/canvas/#text_sizetext-centertrue-max_widthnone-style_args This should give you width and height of your text. Together with the starting position you shou…

Ok, so I will close this one.

Hi Leonardo, First, it should be if button_fine == 'yes': not [button_fine] (Otherwise you compare whether a list is a string which is always false. Second, you should put the entire code of the inline_script new2_inline_script into the run phase…

Hi Natasha, Sorry for the late reply. If you want a precise trigger whenever a specific word in a sentence is being presented, there is no other way than to split up to recording into multiple recordings (per utterance), and send the trigger before…
-
Hi Henk, Can you update your version? That problem has been fixed in the end of last year, so if you have the latest version, it should actually not show this problem anymore. Eduard

Then everything is good indeed :)

Hi, I can't see anything obviously wrong with it. That being said it also crashes on my system with some errors related to the audio (below my tracestack for completeness sake). Not sure whether this is it, but the problems disappear after I delete…
-
For example, where should I include the script if I want to send a log message about the beginning of the object in the spoken sentence (in the practice loop, I have a variable "object_time" with all the object times in milliseconds)? Gene…

Hi @natasha_basil_ Can you share the experiment? Perhaps we can recover some of it content. Eduard
-
Thanks for reporting. It is being tracked here
-
Hi @zhane, Honestly, my advice would be to just use another key (z and m is quite standard for example). If you want to find out what happens, you could leave the allowed-keys field empty, and then check the logfile what key was pressed. Perhaps t…
-
Hi Lena, if you use the same variable name in the sketchpad, it should present the same image (unless you change the variable in between the sketchpads). Eduard
-
Hi Lena, Ideally the trigger for the EEG would be send after each step in the structure You can use this experiment for inspiration (EEG interactions via a parallel port). Essentially you can use the function sendTrigger(defined in helper_function…
-
Hi Natasha, . I need to measure the proportions of fixations to each picture averaged on the following time windows Do you need this information during the experiment or only for later analyses? If latter, I would recommend you leave this out of th…
-
Oh sorry, I didn't know that. I usually use Eyelink trackers. No, unfortunately, I have no idea whether this is still an issue. Eduard
-
upload it elsewhere and share the link here. e.g. wetransfer

If you need keyrelease across sketchpads, you need to use an inline_script to present visual stimuli and a poll the key release function. Something like that: # define the Canvas objects cv1 = Canvas() cv2 = Canvas() # define the Keyboard kb = Key…
-
I have managed to solve the problem just by changing the button box and instead of using the srbox function I am using the keyboard responses. Nice to hear! The experiment was working perfectly and without any change, I am now getting this message: …

Hi @burakcelik, You could check out the Pygaze analyser: http://www.pygaze.org/ There are probably other tools and examples if you google (I am only familiar with Pygaze) Eduard
-
Hi, I suppose you need to install the tobii api (pip install tobii_research) See here: https://developer.tobiipro.com/python/python-getting-started.html Eduard
-
You could add three items to the sequence: subblock1 (run_if: order =1) sublock2 (run_if: always) subblock1 (run_if: order =2) Like that, you could counterbalance the order. Depending on how you define the variable order, you can also randomize the …
-
Hi, If you check the general properties tab (first item in the overview area), you can see the dimension of the experimental window. If that is smaller than the screen, the residual area is filled (and not responsive for the experiment) I am settin…
-
Hi, Not sure whether this is the best approach using the gui, but you could try to separate the two operations into two separate block loops. Alternatively, you might want to think about using plain Python code (within the inline_script item) to ach…

Hi @Varsoviaa, see here for a list of compatible eye trackers: https://osdoc.cogsci.nl/4.0/manual/eyetracking/pygaze/#supported-eye-trackers (and also some more information on eye tracking and Opensesame and Pygaze) Eduard
