Hi Timo, To quote @sebastiaan : (Quote) If you switch them off, do you still get the error? Still, it shouldn't crash normally, even if those extensions are installed, but handle it somewhat more gracefully. Maybe you can make a bug report on gith…

Hi Celine, How do you present the images? In sketchpads or via inline_scripts? If sketchpads, then have a look at the beginner's tutorial. It is described how to present images there. If you use python code, check out this part of the documentation…

Hi, Attached an example script that should get you started. Hope this helps. Eduard (Quote) Check out our tutorials and browse through the documentantion. You will learn a lot by doing so!

Hi, The search function is actually on the left side (see attachment) and (somewhat) limit the search to the forum. Are you using the correct search field? Eduard

Hi Edwin, If you need just one block, you just wouldn't add any block loop, This is certainly possible. Attached you find a simple example of an experiment with only one block of 10 trials. (Quote) Not sure what you mean by that. If you want your …

Hi Anysha, If the experiment worked before and you just changed the file names and files, this error shouldn't occur (as it has nothing to do with images per se). However, from the error message itself it is hard to say what is going on. Would you …

Hi Andrada, What you are describing is very similar to the idea behind the experiment in the step-by-step tutorial. If work through it you should learn how to randomize stimuli across trials and how to present them at certain locations in the displ…

Hi Andrea, (Quote) See the attached screenshot.

Hi, I don't think such a platform exists. You would probably have to instruct participants how to install Opensesame. Maybe this here is also something for you: https://www.labvanced.com/index.html Good luck, Eduard
-
You mean the entire discussion? If you managed, could you share your code for other users that might have similar ideas? Thanks, Eduard
-
Yes, that's right. If I have time in the next days, I will write a little template for you. If you look for " moving stimuli" you'll probably (hopefully) find something. Also keep in mind that the new Opensesame (3.2) comes with very rel…

Hi Biff, Quite certainly, yes. This shouldn't be a problem. If you browse the forum, you should find a few discussion that might get you started. Good luck and if you get stuck let us know. Eduaard

Hi Kiki, No, in this case it is not necessary to have multiple target variables and correct_response variables. I assumed you meant multiple targets within a a single trial iteration, but given your trial structure, this is not the case. Hm, if yo…
-
Hi Andrea, (Quote) The default documentation that you use when you go on www.osdoc.cogsci.nl, is for the most recent version of Opensesame, which is currently 3.2. I suppose you are still using 3.1.9? The change from lower to uppercase was introduc…
-
Hi Rachel, Could this be because you don't have a question defined for most of the sentences in your loop table? Also, I recommend that you don't run it randomized, but sequentially. Like that you have more control over when exactly something break…
-
Hi, (Quote) I would, but I generally prefer inline_scripts. Maybe you can accomplish your design also with loop tables, but I can't think of an easy way to do that. One thing, I'm not sure I get correctly: (Quote) That is, 20 trials with the all …
-
Hi Maxime, Sorry for the delay. I hope it will still be useful to you... (Quote) That is weird. Your experiment is very simple and I don't see where very long delays should originate from. One thing that you can do is set the sound field in the s…
-
Hi, I'm not sure what exactly is going on here, but your experimental sequence is a little messed up. The variable Statement appears in the variable list, but is defined in a source (block_loop_1), that itself doesn't really exist, or at least only…
-
Hi Michael, Can you share your experimental structure with us? That way, it will be easier to find out what is wrong with your code. Eduard
-
Hi, If you run your experiment for a few trials (without coding all special cases), you can have a look at the logfile and check out the all the variables. You will see that Opensesame automatically generates count_XX variables. These keep track h…
-
Hi, The current problem with your experiment is that you haven't specified which sound you want to play in the sound_sampler item (see step8). If you pay close attention to the error message in the debug window, you might be able to fix these kind …
-
Hi David, Would you mind sharing your experiment? Then, I could have a look. Besides, the newest version of Opensesame (3.2.1), has a new feature that is called form validation. With that you don't need to have this extra inline_script, but you ca…
-
Hi Darvas, You have two options here. 1) Set the run_if field of the next stimulus to [response] != 't' However, this only works if the next stimulus that you refer to, is not the next trial, but just another stimulus in the current trial_sequence…
-
Hi stacey, Do the images have at least the same ratio? If so, you could compute the scaling factor based on the information you have, that is, image dimensions and screen dimensions: var.scale = image_width / float(var.width) # var.width represent…
-
Hi Naomi, Did you manage to fix this by now? (Quote) This approach looks very reasonable (except the typo...). Can you test whether this works? So, just create a brief testing experiment and see whether you can access the list at a later stage in …
-
Hi Paul, The trick is to set the timeout of the keyboard response to a very low number. Like that Opensesame won't wait for a long time until a click occurs, but just keeps on running code. If you have all the code in a while loop, Opensesame keeps…
-
Hi, Set the timeout of the sketchpad to 0 instead of keypress. Normally this resolves the issue. Does it for you? Eduard
-
It might be less messy, if you use the same variable names in all sequences. At least, you will end up with less columns, but it is very possible that data analysis gets messier because of that. Try if for yourself and see what it shall be :smile: …
-
Hi Naomi, Instead of a circle, draw an image. To change the calibration sound, try to add this code here to the loop Sebastiaan posted earlier. src = pool['bark.ogg'] # replace bark.ogg with the sound you wish and put that sound file in the file …
-
Hi Tim, Did you have a look at this page? it describes how to write a co-routine with inline_scripts (it behaves a little different than other items). By the way, there is also the responses object. It has the history of all keyboard presses in it…
