Hi Katherina, If timing is important, voice key could be a problem as it is not particular reliable/accurate (just imagine all the unrelated sounds/soft voices/ coughs/ etc that could cause misses and false alarms). So, maybe it might even to make …

I am not sure I understand. Is the problem that in every trial (loop iteration), you see both "from_german" and "from_english" sketchpads? if so, you need to specify in the run_if field of each sketchpad under which conditions yo…

Hi, Do you want to measure the duration of the time that participants can keep on holding down the space bar? Or do you want them to repeatedly press during a minute, and count the number of times they pressed the space bar? In the second case, you…

Very nice!

Hi Hülya, Not sure why the sketchpad wouldn't be able to adjust the font on a trial by trial basis. Perhaps it helps if you embed the text that you want to show in html syntax? Normally this is more powerful and flexible that the standard Opensesam…

Hi Zoe, One way to go about finding out what is happening, is logging all the information that are used to compute accurracy. So the response and the correct_response. If they seem to match for incorrect trials (according to your correct variable),…
-
Hi, Could you upload your experiment? Maybe there is something wrong that I can spot. Please also include the file pool (the images for one trial are sufficient). Thanks, Eduard
-
Hi, Sketchpads are drawn in the prepare phase, the response is only generated in the run phase. Therefore, when you calculating durations and other variables for sketchpads, you can't use the current response. Instead, you have to ether use inline_…
-
Hi Nicole, As far as I know Opensesame returns the response times with a greater precision that 1ms (in the data that I have, all time columns have far more than ms precision. I'd be surprised if this was different for you. Are you talking about th…

I don't know for sure, but it sounds that the comparison on trial 4 is done with information from trial 3, e.g. the start time is used from trial 3, like that on trial 4 the trial seems to last already for a long time, so that the response time on t…

Hi Andreas, I am not sure I fully understand your first point, but both problems seem to be fixable with the inline javascripts, no? You could implement your own randomization in it, and set experimental variables once you are done. So basically, c…
-
Hi Anaïs, No, it does not. It only sends triggers to the eyetracker. In order to communicate with the EEG system you typically have to communicate via the parallel port. def sendTrigger(trigger,port=0x378): global io try: io.DlPortWrit…

Hi, If you want to run your experiment online you have to translate your python inline scripts to javascript inline script. See here: https://osdoc.cogsci.nl/3.3/manual/osweb/#inline-javascript Note, that not all functions are supported in the onl…

Hi Hulya, One way of doing it is giving the files the same names (except the ending of course). Like that, you can code the name in the loop table and load the corresponding variables. Presenting pictures next to the text is not particularly hard. T…

Hi Emilie, One starting point to check the priors is this paper: https://link.springer.com/article/10.3758/s13423-017-1323-7 If this is not enough, EJ will be able to tell yo more. Eduard

HI LL, Can you share the experiment? Then I can help you I think. If not, can you explain what you mean with "second turn"? Eduard
-
Hi, I suppose this question is over JASP? I will move the question to the proper subforum. Eduard
-
Hi, I don't have enough experience with video playback to be sure, but could this problem be related to Opensesame not finding the video you are trying to play? So, do the filenames match? Are the files in the correct folder? Other than that, I don…
-
Hi, Can you try whether the problem was resolved in the 3.3.1 release? If not, could you post this issue on github? I can imagine it is frustrating if your experiment doesn't work after an update. But ideally we would want to fix it, rather than ju…
-
Hi, I don't know whether this is different from the regular experiment (it shouldn't), but normally, the average_response_time variable codes the response time, averaged since the last time the feedback has been reset, whereas the variable response…
-
Hi, Yes, please, send the script. As a disclaimer, if you prepare this experiment for an online study, I won't be help you much as I have not worked with osweb yet. Eduard
-
Hi Intan, THis sounds like a bug, could you report it on the github page? The link is this one: https://github.com/smathot/osweb Thanks, Eduard
-
I think the responses object is only available if you have given at least one response. Therefore, checking it in the beginning of the experiment when you have collected any responses yet, won't work. Try to insert the code in the end of a block or …
-
Then try putting it in the run phase (sorry should have mentioned that earlier)
-
Do you happen to have put the code in the prepare phase? Otherwise, can you share the experiment? Eduard
-
Hi Elisabeth, Unfortunately, that is not possible. You have to recreate the experiment again. Of course you can use your experiment as template, but most of the work is not transferable. Eduard
-
Hi, Opensesame keeps track of all the responses in the responses object. See here for the documentation: https://osdoc.cogsci.nl/3.3/manual/python/responses/ eduard

Hi Michel, Given that this error occurred with the very recent 3.3 version of OS, github would be a better place for this message. This clearly looks like a bug that needs to be fixed in further maintenance releases. https://github.com/smathot/Ope…

Hi Elisabeth, Yes, existing variables are written every time you call a logger, even if their values don't change. Therefore, if your Block A variables are set to 4, they will stay at 4 and written to the logfile as 4 even during B blocks. Normally…

Hi, What do you mean with force? You can stall the experiment until a keypress has been made. To do so, you need to set duration of the stimulus to keypress. If you still need to stimulus to be on screen for only 2 seconds, you can use 2 sketchpads…
