Hi @MelieMeric, Thanks for sending a stripped down version of your task. That's been quite helpful. Ok, so we have established that the issue relates to the parsing of the condition under the "Run if" parameter when the experiment is runni…

Hi @Mnemosyne, The simplest method to display one picture after a correct response and another after an error is to include two feedback objects in your sequence and condition their appearance using the "Run if" parameter in the sequence s…

Hi @MelieMeric, It looks like you're using a form_base, but these are not supported under OSWeb, so I'm a little puzzled by your post. Are you using Open Sesame 4? Perhaps you can upload a stripped down version of your task with the form? Best, Fabr…

Hi @MelieMeric, I'm a little puzzled by your attempt to edit the sequence script. You shouldn't modify it, whether you're running your task in OS or in the browser. You'd only use Javascript in inline:Javascript objects, not in the script of sequenc…

Hi @Zehan, I understand you don't want the pairs of pictures to be fixed and the same for all participants but I don't really understand the rest of your description. Are you using different sets of pictures for conditions A and B or are they all dr…

Hi @Zehan, I'm having some difficulty understanding your description but I think that what you mean is that you want to run two conditions (A and B) with different probabilties: A should run 60 times and B should run 40 times. The simplest way is to…

Hi @multanip, If I understand correctly your description, you are using a single loop with 40 rows and present it sequentially (that is in the same fixed order for all participants, not in a random order), There are several ways in which you can ins…
-
Hi @Lorenzon, @eduard's suggestions should both be able to solve your issue. A third way would be to have a trial inclusing a sound, the visual stimulus and a sound again, and to condition the presentation of the first and the second sound (using th…
-
Hi @reirei, This is happening because you placed a single instance of the log at the end of your task. The logger saves all of the variables from the task with the value they contain at the moment the log is run. Hence, if you run the log only once …

Hi @SpacePenguins & @Silk, It canm be done with eveything inside an inline_HTML object. I've tested the following task with OSWeb 2.1.2.0 and again after updating to 2.2.1.1, using Chrome and using Edge in Windows. Worked without any issue. Not …

Hi @sotake24, The form_base is indeed not currently supported in OSWeb. However, you can use the inline_javascript or the inline_html to achieve the same result. A simple way to show a picture and take a response frmo the participant is to use the h…

Hi @ypark133, You should use the feedback object instead of a sketchpad, because as I pointed out in my reply to your other message (https://forum.cogsci.nl/discussion/comment/29490#Comment_29490), sketchpads are drawn before the trial runs, such th…

Hi @elisevt, Glad I could help! Good luck with your experiment! Cheers, Fabrice.

Hi @rania_tach, Glad I could help! Good luck with your experiment! Cheers, Fabrice.

Hi @rania_tach, I believe that you are measuring time using different references. Your t1 is the response time measure by the keyboard object. The time.time() function in Python measures the current time in seconds since the Unix epoch, which is def…
-
Hi @ypark133, So, you're using two loops with 55 trials in each loop? This doesn't match pictures you showed earlier where you had at least 6 distimct sequences (one called Trial1, another called Trial2 etc.). I think you haven't grasped the concept…
-
Hi @ypark133, Just dragging the code written for another program into yours is likely to present problems. You need to adapt it to your task. In the present case, based on your description, the error message is telling what's going on: when the code…
-
Hi @ypark133, I saw your reply by chance. Best is to use user handles (e.g., @Fab), that way, I get notified of the arrival of a message where I'm mentionned. I'm a little puzzled by your message and your use of a unique sequence for each trial. Is …
-
Hi @ypark133, Yes, both things are possible. Regarding issue (1) which is not strictly counterbalancing but more randomization of subsets of your trials, the simplest method is to place your Q1-Q4 trials in a first loop, and your Q5-Q8 trials in a s…
-
Hi @CarlaC, I don't think there is a way to prevent that. You may want to examine whether your experiment can be condensed using some coding (if the expeirment contains a lot of redundancies, it most often be shortened using some programming). Also…
-
Hi @elisevt, Here's a hybrid solution using code inspired from that you found. It kind of works, with one limitation: it is not possible to enforce a strict timeout on the keyboard object using that method. This is because the keyboard call awaits a…

Hi @zhane, Please do not double post, as it just creates confusion. I'm closing this thread. Please you your first message: https://forum.cogsci.nl/discussion/9151/help-needed-with-response-keys-in-open-sesame#latest Fabrice.
-
Hi @zhane, Difficult to tell what is going on without more information and possibly having a look at your task or a stripped down version of it. It the task worked and it suddenly no longer does, you mat have introduced some change, so it's a matter…

Hi @bkogan86, Can you clarify what kind of object contains that text? inline_javascript? inline_html? Something else? Fabrice.
-
Hi @CarlaC, The following method might for for you (I tried it and it worked in Chrome; I assume it should work in all browsers): Insert a inline_javascript object with the following code at the very beginning of your task: document.querySelectorAll…
-
Hi @LillianCox, I'm not involved in the development of Open Sesame, but I don't think what you are trying to do is possible. I'm pretty sure that verion 4 contains changes under the bonnet that are saved with the experiment and that version 3 isn't …
-
Hi @CarlaC, It is generally not a good idea to multiply the loggers, but it's not really possible to address the issue in your specific cae without seeing exactly how you've implemented the logger. Could you post your experiment to this forum (or a …
-
Hi @sophiie, The easiest way to deal with if your experiement was not running in a browser would be to use the constrain command in the loop's script. However, This function is not currently supported by OSWeb. So I can think of two options in your …
-
Hi @Greg, You'll need to modify your task to replace all the keyboard oobject by mouse response objects and add in the necessary bits to identify what participants have clcked on (or in your case, touched). You can find information about the mouse r…

Hi @CarlaC, I'm not sure how you display your circles, whether you somehow draw then using coding or whether you're using pictures (most probably you're doing the latter). Regions of interest are indeed related to the objects and pictures are rectan…
