Hi Annika, What is your current approach? I have not much experience with video recording from the webcam, but it sounds like something OpenCV should be able to do. You would need to install and import this Python package. Then you should be able t…

Hi Laura, Normally, you can add a column to your loop table that codes the correct response for a given trial. Then you can use this variable to set as allowed response for a particular trial. This procedure is explained in the step-by-step tutoria…

I don't know whether and how this would be possible. Can you maybe elaborate in how far this would be a problem? Thanks, Eduard

Hi dn1, Do you need the RTs in the experiment, or only during data analysis? If the latter, I would suggest you don't bother to implement average RTs inside Opensesame, but only do it in the data analysis in whichever software you use. but I don't…

To add on this, it depends on the precision you need. Both keyboard responses as well as button boxes are reasonably accurate, but button boxes are generally better. If you don't run experiments in which every ms counts, a keyboard will probably do,…

Hi Marta, Have you checked other discussions? Like these here: https://forum.cogsci.nl/discussion/2535/mouse-pointer-not-hidden https://forum.cogsci.nl/discussion/comment/11667#Comment_11667 I hope it helps! eduard

HI laura, i replied in the other thread. Let's try to keep the forum clean, by not posting the same question in different threads. Thanks, Eduard

HI Laura, It isn't quite clear yet what exactly it is that you want to accomplish. If you only want the experiment to proceed if participants press the correct button, you could allow only that single button, right? Do you also need to record all …

Hey, Could you try other stimuli? Like showing another sketchpad with other stimulus information. Also, can you try a different backend? I have never seen such a problem before. Doesn't look like something Opensesame related, more like something on…

@afkeve for convenience sake, I'll move this discussion to the mousetrap channel. Maybe @Pascal can give his opinion on whether an online mousetrap plugin is soon to be expected or not. Eduard

HI Stephan, Try exp.end(), or experiment.end() (My answer is inspired from line 538 on this Opensesame file on github, but untested) Hope it helps! Eduard

I haven't followed the complete discussion, but if you have a sketchpad that is being executed (run_if statement is set to always, or evaluates to True), and there is no delay between the inline_script and the sketchpad, the sketchpad will override …

I am sorry for the confusion...and what do you mean by explicitly computing them? One by one substraction for every two consecutive item? Yes. If you want to know the time difference between sketchpad1 and sketchpad2, you compute it by presentation_…

Hi, I don't know exactly how much delay to expect, but this paper here: https://peerj.com/articles/9414/ might be a good starting point to find out. Potentially, also this website (if you use the psychopy backend): https://www.psychopy.org/general/…

Very cool! If you eventually make your experiment work, it would be nice if you could post your code/experiment. This might be interesting for other users. Thanks

Hi, I have not tested the code, but does this make sense? Basically include the drawing and showing a canvas inside the while loop. target_answer_canvas = Canvas() resp = "" #here we store the response target_answer_canvas.text = Text(…

Hi Lisa, I don't think you can directly use the pygaze functions. As these are also used by the plugins in Opensesame. Instead, I would recommend you go through the source code of Pygaze and try to follow how connections with the Eyetracker is esta…

Hi, I am pretty sure there is a related discussion but couldn't find it. I am also pretty sure, but I can't find it either. You don't need 30 sketchpads. One sketchpad is sufficient if you put the content on it by means of variables. Check out the …

Hi Schmit, I have never tried that but I doubt that this is possible. Generally, it helps to have shorter loops. So if you can see yourself shortening your loops, your delay might shrink to an acceptable level. What you can also try, is accessing …

Hi, I would like to send multiple triggers for each sentence, for example at the start of the sentence, the start of the target word and the end of the sentence. My question is how to arrange this. On the Forum I could only find examples of scripts…

Hi, I think this part of Cleroux's response is relevant: how can I restrict the click on only the ROI (ignoring a click on "nothing") ... was quite obvious using 'repeat cycle' with ''[cursor_roi] != 'Diff' and [cursor_roi] != 'Ident'' ..…
-
Hi, And also here you say "time_variablename" means the timestamp of when that sketchpad is shown since the beginning of the experiment. In my case, do I need to use that? That is up to you, most (if not all) of the response time measure …

HI Katherina, I couldnt find out what exactly is causing this weird behaviour (there are multiple aspects at work to produce such behaviour), but in any case, the attached script should solve your issues. Hope this is somewhat useful. Eduard https…

Hi DK, If your screen is made up the same way in the two phases, there is no reason why the word dog should appear at the same location. If there are other information on the screen, you indeed need to make sure that the position is close to identi…

Hi Igotta, Maybe it is already sufficient, to scale down the images? What resolution does one image have? If it is several MB, and you can reduce it to a few hundred KB, you should not run into problems. If it turns out to be too big after all, wri…

@sebastiaan, I can confirm that the generated gabors cannot be accessed. Eduard

Hi Sandy, Yes, that is what I mean. You could even write your own bat file (in which you already specified the settings for opensesamerun.bat), so that a double click on it starts the experiment right away. That shouldn't be too complicated. Ps. D…

Hi Ali, Have you already figured this out? You don't need to "bug" the experiment. If you don't run the experiment full screen, you can monitor the debug window while doing the experiment. Eduard
